Western Governors University Abstract
Article Larose J; Sigal RJ; Khandwala F; Prud'homme D; Boulé NG; Kenny GP. (2011 January). Associations between Physical Fitness and Glucosylated Hemoglobin in Type 2 Diabetes Mellitus. Diabetologia, 54(1), 93-102. Retrieved May 17, 2012, from MEDLINE database. 20953579

Background Information Exercise and physical activity has shown to be a significant factor in the management and treatment of diabetes. What is unknown is how benefits from physical activity directly correlate to glucose control as manifested in low glucosylated hemoglobin (HbA1c) levels in diabetic people. The study aims to prove that the decrease in HbA1c is a result of greater aerobic fitness and strength in patients that are performing aerobic or anaerobic exercise. Secondly, it is related to the changes in strength and aerobic fitness that are performing cardiovascular exercise and resistance training.
Review of Literature The purpose of the article is to assess the correlation of reduced HbA1c to physical activity. It is hypothesized that this reduction is related to the changes and increase in aerobic fitness and strength in diabetic people who are engaged in aerobic and anaerobic exercise. The result from the study showed that the link between the changes in glucose control during exercise training is not that high nevertheless; physical activity offers health benefits to diabetic patients.
Methodology The study used experimental method by randomized controlled trial. Random sampling of 251 patients between 39-70 years old with type 2 diabetes mellitus that were previously sedentary was allocated aerobic, resistance, or aerobic plus resistance, or to a control group that was sedentary.
The participants were evaluated prior to the run-in phase (baseline) and at the end of intervention (6 months). The trials consist of 4-week run-in phase and followed by a 22-week intervention phase. Participants performed 15-20 minutes aerobic exercise at moderate intensity (60% VO2 peak) three times a week and one to two sets of seven resistance exercises at moderate intensity twice a week under supervision. Included on the randomization are participants who joined in 10 or more exercise session in the run-in period. Randomization was stratified by age and sex.
HbA1c and cardiorespiratory fitness level from each participant were measure to establish baseline and post intervention testing.

Data Analysis The article analyzed the collected data by measuring health status at baseline, midpoint and end of the study. Factors measured in the study included methods of exercise, which are resistance, aerobic, a combination of both and control. Physical fitness and changes in HbA1c among the exercise groups, was measured of peak oxygen consumption, workload, treadmill time, ventilatory threshold, seated row, leg press and bench press
Conclusion The results of the research showed that both aerobic and resistance training alone lead to the decrease in HbA1c when compared to the control group. There was a greater decrease in HbA1 in the group that performed both aerobic and anaerobic training. There is noted significant reduction in body weight in aerobic training participants. No significant changes in weight where noted in the group that did combined exercise training compared to the aerobic group. Improvements in cardiorespiratory fitness also resulted in better HbA1c. The study also shows that the gains in strengths as a result of resistance training have a direct correlation to improvements in HbA1c. The experiments supports the notion that combined exercise training is the most effective and beneficial for people with type 2 diabetes and improvements in fitness level as a result of aerobic and resistance training are associated with better glucose control.

A3. Assessment of Evidence:
In review of the article, the experiment was well developed and established. A run-in phase was done prior to the implementation phase. Only those that participated in 10 or greater schedule exercise sessions where included in the randomization to maintain compliance. Baseline data was established prior to the run-in phase and at the end of the intervention to establish a comparison.
Results indicate that cardio-respiratory changes as a result of aerobic training is a much better indicator of lowering levels of Hb1Ac than strength training. Much less conclusive is a possible strong connection between fitness and glucose control which suggesting that changes in glucose control during exercise training are not entirely dependent on improvements in fitness.

A4. Ethical Issues:
It was stated that participants for the study were recruited by word of mouth, physician encouragement and advertising. Informed consent was obtained accordingly but it was not stated in the paper how the results from the study was going be utilize and who will have access to the data. It was not mentioned whether the results would be shared to the participants individually or as a group, which can be a source of concern for some individuals since some people are very private. Health status is something that is very personal. The researchers have to be cautious and sensitive to this because the participants may not want their health status known to the group.

A5a. Types of Research:
The research was a primary research that used a randomized controlled trial. A random sampling of 251 participants with type 2 diabetes was recruited. Final participants where selected by implementing a run-in phase where only those that attended 10 or more scheduled sessions were included in the implementation phase for the next 6 months. The participants were divided into different groups. One group performed aerobic exercise that lasted 15- 20 minutes at moderate intensity that gradually increased to a maximum of 45 minutes at high intensity three times a week. The second group performed resistance training that involved two different seven training exercises, which focused on all major muscle groups two times a week. The third group performed both the aerobic and resistance training exercises. A control group was also established and remained sedentary.

A5b. Other Types of Research:
I believe that the use of randomized controlled trial was effective in determining the correlation of physical activity and improvement of glucosylated hemoglobin for the management of diabetes. Randomizing the study provides equal opportunity for the selected population group to be represented. Randomized sample selection of participants was important to preserve the objectiveness of the study.
Prior to the testing phase, the researchers ensured that the participant would be compliant with the experiment by doing a run-in phase. Only the ones that participated in 10 or more scheduled exercise session where included in the randomization. Randomization was further stratified by age and sex.
By using randomized control trial, the study was able to compare and contrast the results from participants that performed aerobic exercise, resistance training, combination exercise training and the control. It was able to effectively measure the gains of physical activity in reducing HbA1c to control diabetes.
B1. Problem:
The number of people who have diabetes in the United States is a staggering 26 million. An estimated 79 million adults are prediabetic. Prediabetes is a condition where the blood sugar of an individual is high but not high enough to be diagnosed as diabetic. A person who is prediabetic is at increase risk for developing type 2 diabetes mellitus.
It important to educated and engages this group into the benefits of physical activity and how it affects the glucose level of an individual. Being able to prevent the development of diabetes by using physical activity will significantly help the nation. The cost is remarkably less than pharmaceutical interventions. Besides lowering glucose level, physical activities have other benefits such as improved cardiovascular health, increased bone density and strengthen muscles, weight control, better self-esteem and enhanced mental health and mood.

Diabetes is prevalent not only in adults but also in adolescents. Results of engaging in physical activity are similar to adolescents when compared to adults. Adolescents who participate in exercise regimen have a lower level of blood glucose in relation to those who are sedentary. Having control of the disease during adolescent years results in better management in older years and lowers the other risk factors associated with diabetes.

In this article, the authors reviewed different studies. One of the studies included the relationship of exercise and diabetes. Exercise is one of the key components in the foundation of a healthy lifestyle. The study concludes that regular aerobic exercise enhances sensivity to insulin, promotes cardio-respiratory functions decreasing cardiovascular risk on pre-diabetic and diabetic patients. Regular monitoring of exercise effectively decreased the HbA1c level, fasting glucose level and body mass index and also improve the general over all wellbeing of patients.

The article shows evidence that both aerobic and anaerobic exercise is beneficial to diabetics. When they engage in regular physical exercise, their cardiovascular health status improves that results in a decrease in the glucose level. The research shows that aerobic exercise combined with strength training is most advantageous to managing diabetes.

B3b. Efficacy:
Overall, the articles reviewed were effectious in the research performed. The randomized controlled study and cohort methods used in research resulted in positive outcomes. Possible outcomes have been identified prior to the research implementation. The evidence shows in all the articles that exercise whether aerobic or anaerobic can have significant impact on the blood glucose level on a diabetic patient. During the research studies, it proved that consistency in participation and management of regimented exercise plan improves cardiovascular health that result in lower levels of blood glucose for diabetic patient and prevention of diabetes mellitus II in pre-diabetic individuals.

B3c. Tools:
The different studies used similar tools to measure the variables. For example, multiple researchers used either a treadmill or a cycling machine to control the length of aerobic exercise of the participants. Exercise equipment were utilize for anaerobic exercises. Other tools that were used are weighing scale, tape measure and sphygmomanometer. Baseline data was obtained prior to the study. Same tools were utilized to measure changes in the participant health status during and after the study. Pedometer and heart rate monitors where employed during aerobic exercises to measure activity of participants.
B3d.
The tools use for the research did not affect the results. The outcomes are measured quantitatively for example, cardiovascular fitness was objectively measured the comparing the distance covered within a period of time while performing aerobic exercise. There results from the researchers where mechanically measured that would prevent subjectivity in obtaining data. Changes in the health status of the participants were measured by comparing the results from baseline figures such as weight, heart rate, tolerance to exercise and level of blood glucose. Reported data is collected objectively by using factual results on the variable that were being measured.
B4. Evidence Summary of Articles:
In summary, active participation in consistent physical activity that involves both aerobic and anaerobic exercise is effective in improving the glycaemic control in patients with diabetes. Other benefits of exercise include increase cardiovascular fitness, weight loss, boost in self esteem and lowers additional health complications that are associated with diabetes such as peripheral neuropathy, cataracts and glaucoma.
B5. Recommendation
I believe that the different article show enough evidence to support the statement that regular physical activity is beneficial and effective in managing and preventing type 2 diabetes by lowering blood glucose level. In each of the articles, there were measurable marked improvements in the individual’s heath status.
Knowing physical activity as simple as walking and cycling can help manage and prevent diabetes is important to share this information to patients. Patient education is key in successful prevention or managing of diabetes that is responsible for reduced quality of life of those afflicted. I would create a handout that would include fact about diabetes. Definition of diabetes, complications of the disease, how to effectively manage diabetes and the importance of actively engaging and committing to life style changes will be in the handout. This will be written in laymen’s terms that is simple and easy to understand. I will review the handout with the patient and set some goals that would include physical activity. I would encourage the patient to write the goals in a journal and keep track of his/her progress weekly.
It is valuable to engage the patient in setting their own goal because they know best what their limitations and abilities are. It also critical to celebrate progress and achievement of goals as a tools for motivation for the patient.
B6. Theoretical Models: Theoretical models are important when planning the framework for nursing research. There are different types of theories from grand theories to middle range, borrowed, shared and microtherios. Each is important in creating and performing research. Results from sound and effective research studies often translate into implementation of changes in nursing practices that have opportunities for improvement. New nursing practices and standard of care are a direct result of evidence-based. Using both theoretical and conceptual frameworks is critical in establishing a well-structured research study. Research study that is logical and coherent will lend itself to become credible and allot for cross-reference and comparison among studies. Establishing a strong framework is a critical ingredient of a good research. Performing a research that is superior is of necessity because of the impact that it can create on a population of people.
Established theoretical nursing models help defined the research. It allows for promotion of new knowledge because of it’s credibility. Maintains continued knowledge exchange and synthesis of action and inquiry. Creation and implementation of research study and keeps the researchers to stay objective and factual in their pursuit.

...Diabetes Overview Almost everyone knows someone who has diabetes. An estimated 23.6 million people in the United States—7.8 percent of the population—have diabetes, a serious, lifelong condition. Of those, 17.9 million have been diagnosed, and 5.7 million have not yet been diagnosed. In 2007, about 1.6 million people ages 20 or older were diagnosed with diabetes. … Source: 2003-2006 National Health and Nutrition Examination Survey estimates of total prevalence-both diagnosed and undiagnosed-were projected to year 2007. What is diabetes? Diabetes is a disorder of metabolism— the way the body uses digested food for growth and energy. Most of the food people eat is broken down into glucose, the form of sugar in the blood. Glucose is the main source of fuel for the body. After digestion, glucose passes into the bloodstream, where it is used by cells for growth and energy. For glucose to get into cells, insulin must be present. Insulin is a hormone produced by the pancreas, a large gland behind the stomach. When people eat, the pancreas automatically produces the right amount of insulin to move glucose from blood into the cells. In people with diabetes, however, the pancreas either produces little or no insulin, or the cells do not respond appropriately to the insulin that is produced. Glucose builds up in the blood, overflows into the urine, and passes out of the body in the urine. Thus, the body loses its main source of fuel even though the blood contains large amounts of...

...Diabetes Among African Americans Diabetes has been affecting the African American community in the United States for a long time. Diabetes is a disease that occurs in people by altering the body’s metabolic process in producing insulin. Insulin is a hormone that is produced in the pancreas which regulates the amount of sugar in our blood stream, and in turn becomes energy. There are two types of diabetes: type 1diabetes and type 2 diabetes. Type 1diabetes, which usually begins during childhood or adolescence, is a condition characterized by high blood glucose levels caused by lack of insulin (American Diabetes Association). This occurs when the body's immune system attacks the insulin producing beta cells in the pancreas and destroys them. Type 2 diabetes which is the most common form of the disease, usually occurs in middle aged adults after the age of forty-five (American Diabetes Association). It’s a condition characterized by high blood glucose levels caused by either lack of insulin or the body's inability to use insulin efficiently. Forty percent of African American boys and forty nine percent of girls will develop diabetes during their lifetimes and therefore face the possibility of severe diabetes-related complications and a life span that is reduced by 4 to 23 years (Institute for Alternative Futures). In 2010, there were 5,547,700 African Americans in the United States with diabetes. African Americans have at least twice the risk of amputations, renal failure, and...

...Diabetes is a very serious disease that attacks millions of people around the world. It can strike at any age and it can happen to anyone. Diabetes is a disease where the body does not produce enough insulin or properly use insulin causing the body’s own immune system attacking and destroying insulin producing cells in the pancreas. In 2011, statistics show that in United States 25.8 million of children and adults has diabetes (ADA, 2012). Without the use of insulin, the glucose that we need to live on has a hard time entering the cells of the body that needs it. Then again, if there is too much glucose that builds up in the blood then a diabetic patient begins to have headache or blurry vision. They may become very thirsty or have dry itchy skin. If a diabetic patient blood gets too low, he or she may feel tired, hungry, or shaky. They are 3 types of diabetes, both of which are Type 1 diabetes and Type 2 diabetes. The other is gestational diabetes that happens in pregnant woman. Type I diabetes is also known as “Juvenile Diabetes” because it occurs in children and young adults. Type I diabetes that is also known as juvenile diabetes can occur at any age but it is most likely common diagnosed during childhood. In type I diabetes the body does not produce insulin. Insulin a hormone that is needed to convert sugar, starches, and other food into energy needed for daily life (ADA, 2012). This type of diabetes can be treated with either insulin shots or by using an insulin...

...Diabetes Mellitus The term "diabetes mellitus" refers to a group of diseases that affect how your body uses blood glucose, commonly called blood sugar. Glucose is vital to your health because it's an important source of energy for the cells that make up your muscles and tissues. It's your brain's main source of fuel. (Turner, 2010, p.18) of you have diabetes, no matter what type, it means you have too much glucose in your blood, although the reasons may differ. Too much glucose can lead to serious health problems. Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes — when your blood sugar levels are higher than normal, but not high enough to be classified as diabetes — and gestational diabetes, which occurs during pregnancy. (Turner, 2010, p. 22) Diabetes symptoms vary depending on how high your blood sugar is elevated. Some people, especially those with prediabetes or type 2 diabetes, may not experience symptoms initially. In type 1 diabetes, however, symptoms tend to come on quickly and be more severe. Some of the signs and symptoms of type 1 and type 2 diabetes include: Increased thirst Frequent urination Extreme hunger Unexplained weight loss Presence of ketones in the urine (ketones are a byproduct of the breakdown of muscle and fat that happens when there's not enough insulin) Fatigue Blurred vision Slow-healing sores Mild high blood pressure Frequent infections...

...ADAL Tamara Zgadzaj Tutor: Thomas Torley This plan will examine three main long term problems affecting people with diabetes: • eyes • kidneys • heart and brain People with diabetes should visit an eye doctor regularly, every year for an eye exam. Eye problems that can occur with diabetes include : cataracts ( a clouding of the lens ), glaucoma (increased pressure in the eyes ), retinopathy ( eye changes with the retina in the back of the eye ). Symtoms of eye problems are : blurred vision, spots or lines in your vision, watery eyes, eye discomfort, and loss of vision. Diabetics should check for urine problems at least once a year. Proteins in the urine are a sign of kidney disease. Also, blood pressure should be checked regularly. Symtoms of kidney problems can include, swelling of the hands, feet, and face. Weight gain from edema, itching and drowsiness. If they will get promt treatment, there is a chance to slow down the changes in the kidneys. All people with diabetes have increased chance of heart disease and even stroke. Heart disease is the major cause of death for diabetics. It's important to control other risks such as high blood pressure and high fats ( cholesterol ), as well as blood sugar. Symtoms of heart attack are, shortness of breath, feeling faint, feeling dizzy,sweating, nausea, chest pain or pressure, pain in the shoulders, jaw and left arm. Warning signs of stroke are, sudden numbness or weakness in the face,arm, or leg, usually on...

...lead to multiple life threatening diseases, such as diabetes. When people hear the news that they have been diagnosed with diabetes, it makes them feel frightened. In 2011, statistics show that in United States 25.8 million of children and adults has diabetes (American Diabetes Association, 2012). American Indians and Alaska natives have a higher percentage of adults with diabetes than other ethnicities (Collazo-Clavell et all. 2009). Diabetes is a serious life-long illness caused by high level of glucose in the blood. This condition is when the body cannot produce insulin that is located in the pancreas. Insulin is a hormone that moderates the blood level. Diabetes affects the process of how the body uses blood sugar (Collazo-Clavell et all. 2009). Glucose is significant since it is “the main source of fuel” (Collazo-Clavell et all. 2009). There is no cure for diabetes but there are ways to lower the risks. Although diabetes is a disorder, it can also lead to other factors such as heart attack, kidney failure, or death. A person with diabetes has to maintain a healthy lifestyle including eating the right food, exercising, controlling their blood sugar level, and be optimistic. Diabetes occurs in several forms but the major ones are Type I and II diabetes and gestational diabetes. Type I diabetes is also known as “Juvenile Diabetes” because it typically occurs in children and young adults. The symptoms for Type I diabetes are frequent urination, extreme thirst and hunger, unusual...

...DIABETES Definition: Diabetes is a condition where the body fails to utilize ingested glucose. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood – it is the principal source of fuel for our bodies. It’s a metabolism disorderthat causes excessive thirst and production of large amounts of urine because the kidneys fail to conserve water. Metabolism refers to the way our bodies use digested food for energy and growth. When our food is digested, the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present. Insulin is a hormone that is produced by the pancreas. Insulin makes it possible for our cells to take in glucose. Types of Diabetes There are three (3) main types of diabetes. They are Type 1Diabetes, Type 2 Diabetes and Gestational Diabetes. Patients with Type 1 Diabetes usually develop this type of diabetes before their 40th year, often in adulthood or teenage years. In this case, the body does not produce insulin. Some people refer to this type as insulin-dependent diabetes, juvenile diabetes or early-onset diabetes. Patients with Type 1 diabetes will need to take insulin injections for the rest of their life. They must also ensure proper blood-glucose levels by carrying out regular blood tests and following a special diet. Under Type 2 Diabetes, the body does not produce enough insulin for proper function or the cells in...

...Diabetes Dr. Langston Diabetes Mellitus also known as diabetes “dates back to 1500 B.C. nearly 3,500 years ago” (Beaser and Hill, 1995, p.9). Today type 2 diabetes affects millions of people. Currently there is no cure for diabetes. “However, recent advances in genetic engineering technology now offer great promise for overcoming the problems which have frustrated researchers in the past” (Alterman and Kullman, 2000, p. 263). People with diabetes could suffer serious complications such as diabetic ketoacidosis (diabetic coma), arteriosclerosis (hardening of the arteries), hypertension (high blood pressure), heart disease, diabetic neuropathy, and diabetic retinopathy to mention a few. Diabetes is a disease that affects 25.8 million people in the United States alone. This disease results when there is a high level of sugar in the blood for an extended period of time. It can be controlled by diet, exercise, pills and insulin injections. There are three main types of diabetes--Type I, which affects primarily the younger population; Type II, which primarily affects the population above 40; and gestational diabetes, which affects women during the third trimester of their pregnancy. For some people the cause could be the body does not respond to insulin. “Virtually all cells in the body contain special proteins called receptors that bind to insulin. They work like a lock and key. In order for glucose to enter the cell, insulin (the key) must first fit into the insulin...

...wrote about diabetes for my biology research paper. I need someone to proof read for me. It is in APA style. Thank you! =) In America, the fact that fast food restaurants are located at every corner many people becomes obesity leading to huge risk factors. The various issues of unhealthy living lead to multiple life threatening diseases, such as diabetes. When people hear the news that they have been diagnosed with diabetes, it makes them feel frightened. In 2011, statistics show that in United States 25.8 million of children and adults has diabetes (American Diabetes Association, 2012). American Indians and Alaska natives have a higher percentage of adults with diabetes than other ethnicities (Collazo-Clavell et all. 2009). Diabetes is a serious life-long illness caused by high level of glucose in the blood. This condition is when the body cannot produce insulin that is located in the pancreas. Insulin is a hormone that moderates the blood level. Diabetes affects the process of how the body uses blood sugar (Collazo-Clavell et all. 2009). Glucose is significant since it is “the main source of fuel” (Collazo-Clavell et all. 2009). There is no cure for diabetes but there are ways to lower the risks. Although diabetes is a disorder, it can also lead to other factors such as heart attack, kidney failure, or death. A person with diabetes has to maintain a healthy lifestyle including eating the right food, exercising, controlling their blood sugar level, and be optimistic. Diabetes...

...Diabetes: the most common disease that runs in my family A Research Paper Presented In partial Fulfillment of the Course PE 211 04 Health Principles To Professor Earl Henry December 4, 2013 Health Principles December 4, 2013 Abstract Diabetes is a disease that runs on my mother’s side of the family. This paper will pull out the different types of diabetes, type 1 and type 2. Each type has different symptoms that will show the requirements of receiving diabetes. Diabetes can be treated but it can’t be necessarily be curable. It is important that to motivate people to start taking care of their body’s. Young children around the world, especially in America start getting treatments for being diabetic. It is devastating to see young children suffer at young ages because of the foods they eat and not getting plenty of exercises. Having a good health is very important and for young children there should not be any excuses. The reason why I picked this topic is because my mother’s side of my family are diabetics and it is very common to them. My grandmother has to take medications everyday for her diabetes. My family has the decency to take care of their body’s, but it’s a disease that runs in our family. There is a great chance for me in the future to catch this disease if I do not pay attention to my own health. Everett Grant Professor Henry Health Principles December 4, 2013 Diabetes There are many risk factors for type 2 diabetes, it goes through family history...

Diabetes

...Diabetes Diabetes mellitus, or often referred to as diabetes, is a metabolic disease in which a person has high blood sugar. This can happen either because the body does not produce enough insulin, or because the cells in the body do not respond to the insulin that is produced. Insulin is the hormone that unwinds the cells of the body, allowing glucose to enter and fuel them. Type 1 diabetes results from the body’s failure to produce insulin. This type of diabetes is usually diagnosed in children and young adults. Another name for this type of diabetes is juvenile diabetes. Type 2 diabetes is the most common form of diabetes. In this type either the body does not produce enough insulin or the cells ignore the insulin the body produces. Another type of diabetes is Gestational diabetes, which only occurs in women because it shows up during pregnancy. (Schütze, Rix, Laws, Passey, Fanaian & Harris, 2012) Diabetes can be a serious lifelong disease; which can lead to heart attacks, kidney failures, blindness, and even death. Type 1 diabetes also known as juvenile diabetes is characterized by the body’s immune system destroying insulin-producing cells in the pancreas. Insulin helps the body store Glucose (sugar) in the body. This being said the body cannot regulate blood sugar, and glucose levels rise in the body. Type 1 diabetics need to regulate their blood sugar by taking insulin shots and like both forms of diabetes regulating what is eaten. Because their body is not...

Diabetes

...Diabetes It all starts with the consumption of food that contains carbohydrates. The carbohydrates are then metabolized into a type of sugar called glucose. The body needs glucose because glucose is a source of energy for the cells. After being metabolized, glucose moves into the bloodstream and the body detects that the blood glucose level is rising. In response to this, the pancreas, which is a little gland that sits underneath the stomach, starts releasing a hormone called Insulin. And it’s insulin that helps our bodies get the energy from the food we eat. The bloodstream then takes the glucose and the insulin to every cell in our bodies that needs it. The body functions best when the blood glucose is at an optimum level. It doesn’t respond well to high levels of blood glucose. Normally, there’s a cycle within the body that balances out the glucose and insulin levels. In this case, the food we consume or the liver releases glucose into the bloodstream and the pancreases releases the insulin that carries the glucose to the cells. However, diabetes occurs when this system fails to function properly in the bodies of many individuals today. According to the American Diabetes Association, Diabetes Mellitus is a chronic lifelong condition that affects our body’s ability to use the energy found in food. It is a cellular disease that involves the lack of glucose receptors on cell membranes. Although diabetes is a complex condition, its common theme involves either the lack of insulin...

...People with diabetes suffer from high blood glucose, or blood sugar. The foods we eat create glucose. The glucose is critical to our heath because it creates energy for the cells that make up our muscles and tissues. Insulin is a hormone that helps glucose turn into energy, without it the glucose stays in your body. There are three different types of diabetes. Type 1, your body does not produce insulin. Type 2, the more common, your body does not use or produce insulin well. Gestational diabetes happens during pregnancy, the placenta produces hormones that make cells resistant to insulin. The cause of diabetes is when the pancreas does not produce enough insulin to break down the glucose and turn it into energy. There are serious health risks having too much glucose in your system. There could be damage to the eyes, kidneys and nerves. As well as, cause strokes, heart disease and even the need to remove a limb. Some of the most common symptoms are increased thirst, frequent urination, extreme hunger and unexplained weight loss. If any or all of these symptoms are discovered consult your physician immediately. Certain people have risk factors that can be looked at when trying to diagnose diabetes. There are also genetic factors that can play a part and increase your chances of getting diabetes. Type 1 diabetes is increased if your parent or sibling has this form of diabetes. Type 2 is more likely to develop in people that are overweight or have a family history. Gestational...
