ESSAY ON ANAEMIA
Anemia is a deficiency of red blood cells or hemoglobin in the blood. The word anemia comes from two Greek roots, together meaning “without blood.” At the beginning of the nineteenth century, “anemia” referred to the pallor of the skin and mucous membranes. After medical science advanced, blood cell counts could be done. Anemia became the disease we know today.
Mild anemia may have no outer symptoms. Weakness, fatigue, and pallor are very common symptom. Symptoms of severe anemia are shortness of breath, rapid heartbeat, lightheadedness, headache, ringing in the ears, irritability, restless leg syndrome, mental confusion, dizziness, fainting, and dimmed vision.
Iron deficiency anemia- the most common type of anemia; occurs because of low iron levels. Folic acid deficiency anemia- levels of folic acid are low because of inadequate dietary intake or faulty absorption. Pernicious anemia- inability of the body to properly absorb vitamin B12
Hemolytic anemia- red blood cells are destroyed prematurely.
Sickle cell anemia- inherited abnormality of hemoglobin; occurs mainly in people of African or Mediterranean decent.
Thalassemia anemia- inherited disorder in the synthesis of hemoglobin.
A plastic anemia- decreased bone marrow production.
Determining the cause of anemia is very important because it may be the sign of a very serious illness. A physician should ask about family history of anemia, gallbladder disease, jaundice, and enlarged spleen. A stool test should be done and the physician should check for swollen lymph nodes, an enlarged spleen, and pallor. Laboratory tests can test both the numbers of red blood cells as well as look at their appearance.
Because there are so many different types of anemia as well as causes, treatments vary widely. If the type of anemia results from a vitamin deficiency and there is no underlying cause, treatment

Chronic Anaemia Essay

...Chronic anaemia may result from the malnutrition in dominant EB in recessive forms of EB there is still research being conducted. The rate of anemia is normally higher in EB affected persons than non EB affected persons. There are many reasons the anemia occurs in the EB population. Iron deficiency and protein loss from unhealed wounds are main proponents. Blood transfusions are a tricky topic for this area as some populations may have an iron overload such as those predisposed to sickle cell anemia. Other complications include chronic blood loss from scarring resulting in reduced hemoglobin (Hwang, Shelley Ji Eun et al. 2015).Cardiomyopathy may result as a complication this is where the heart has has a difficult time pumping blood to your...

Discussion Essay

...ASSIGNMENTS 2 DISCUSSION ESSAY Topic: Iron deficiency anaemia is a condition which affects many women during pregnancy, in developing countries. Discuss the causes and effects of iron deficiency anaemia on both mother and baby. Introduction Anaemia in pregnancy continues to be a major public health problem and it affects more than 56 million women worldwide (Imdad, & Bhutta, 2012). The world health organisation estimates that 58% of pregnant women in developing countries are anaemic. The greatest burden of anaemia is borne by Asia and Africa where it is estimated that 60% and 52% of women, respectively, are anaemic, and between 1% and 5% are severely anaemic (Guidotti, 2000). Multiple factors lead to anaemia in pregnancy, nutritional iron deficiency is the most common cause of anaemia (Guidotti, 2000). Iron deficiency anaemia (IDA) is due to insufficient iron, without enough iron, human body can't produce enough haemoglobin, which a substance in red blood cells, so that they cannot carry oxygen to body tissues (Mayo Clinic, 2014). Yong children and pregnant and postpartum women are the most commonly and severely affected because of the high iron demands of infant growth and pregnancy. IDA in pregnancy can be a risk factor for preterm delivery and subsequent low birth weight, and possibly for inferior neonatal health (Allen, 2000). This essay will discuss some of the causes and effects of iron deficiency anaemia on both mother and baby. Body One of the reasons...

Impact of Sickle Cells on Individual

...Freddie Ntunga | Student ID Number: 21608670 Bucks New University Abstract An Essay Discusing the ImpacT of Sickle Cells on an Individual Health & Illness across the Life Span Introduction The concept of health is purely abstract in form and therefore remains indefinable to a great extent. It may be referred to an aspect that is considered to be prima facie with regard to the fulfilment of all kinds of objectives of human life. Being healthy does not essentially refer to being disease free only, as the World Health Organiastion definition of health encompasses a state of well being from the mental, psychological, social and physical perspectives. For providing a comprehensive definition to the concept of health it is vital to focus on the various aspects of health. The definitions of health can either address the functional needs of the humans which would put more attention on the individual’s ability to deal with various kind of situations and head towards its destination or from the humanist approach it can be considered as the state of self actualization that can be linked with empowerment. Health in other words can be stated as a pulpit which begets achievement. Health is the result of the natural environment, the built up environment and the social environment that the individuals are surrounded with from the time of its very conception ( Zhang et al,.2011). The natural environment constitutes the genetic background of the individuals involving certain unique...

Micardic

...Myocardial Infarction Mortality 1.0 Introduction In the UK, about 838,000 men and 394,000 women have had a myocardial infarction (MI) at some point in their lives, (NICE clinical guideline 48, 2007). The latest statistics from the British Heart Foundation state that approximately 227,000 people suffer from an acute MI (heart attack) each year (British Heart Foundation Statistics Website). To put this figure in to perspective this equates to one person every 2 minutes. Mortality is at approximately 30% which is 68,100 deaths in the UK per year. The National Service Framework (NSF) for Coronary Heart disease (CHD) is a 10-year programme published by the Department of Health in 2000 and has set key standards for the prevention and treatment of CHD. Access to the right treatment for those who suffer from an AMI, is essential to reduce morbidity and mortality and improve clinical outcomes. People with diabetes mellitus constitute a group of patients who have a higher risk of having an MI and also a poorer prognosis post infarction. The higher death and complication rates appear to be multifactorial but a significant finding in the Diabetes Mellitus Insulin-Glucose Infusion in Acute Myocardial Infarction (DIGAMI) Trial showed to reduce one year mortality by 30% (Malberg et al., 1995). It’s recommended 1.1 Primary Objective To determine the relationship between HbA1c and prognosis of patients in East Lancashire having a myocardial infarction. 1.2 Secondary Objectives To assess...

Myocardil Effusion

...The aim of this essay is to explore an acute deterioration in the health of an adult I have encountered during a clinical placement, in an acute care setting. The essay will begin with a definition of acute care, followed by the introduction of my patient and predisposing factors. This essay will include an explanation of the significant pathophysiological changes and related clinical manifestations and a critical analysis of the nursing interventions implemented during the acute episode of care, focusing on holistic care, rationale and evidence base. It will then describe the actual deterioration in the patient’s condition, and discuss the nurse’s role in the recognition and assessment of the actual deteriorating condition following the trusts policies. Assessment tools, monitoring, detecting and reporting will be considered. Finally this essay will include a discussion of the importance of multidisciplinary team collaboration in the diagnosis and provision of care during the acute episode, and a discussion on whether the deterioration could have been prevented by identifying any areas of practice which could change in relation to evidence based practice. For the purposes of privacy and confidentiality, in accordance with NMC (2008) code of conduct, the name of the patient will be changed to Peter and the placement area will remain as an acute care setting.

Undernutrition

...Proper nutrition is a powerful good: people who are well nourished are more likely to be healthy, productive and able to learn. Good nutrition benefits families, their communities and the world as a whole. Undernutrition is, by the same logic, devastating. It blunts the intellect, saps the productivity of everyone it touches and perpetuates poverty. Stunting - or low height for age - traps people into a lifelong cycle of poor nutrition, illness, poverty and inequity. The damage to physical and cognitive development, especially during the first two years of a child’s life, is largely irreversible. A child’s poorer school performance results in future income reductions of up to 22 per cent on average. As adults, they are also at increased risk of obesity, diabetes and cardiovascular disease.

...Impact of Poor Nutrition on the Academic Performance of Grade Seven learners: A Case of Zimbabwe Kudzai Chinyoka Great Zimbabwe University Department of Educational Foundations Email: chinyokak@gmail.com Doi:10.5296/ijld.v4i3.6169 URL: http://dx.doi.org/10.5296/ijld.v4i3.6169 Abstract This paper examined the impact of poor nutrition on the academic performance of grade seven learners at two primary schools in Chivi, Zimbabwe. Its main objective is to identify mitigation policies and measures designed to reduce negative effects of poor nutrition on children’s academic performance. Malnutrition remains one of the major obstacles to human well-being affecting all areas of a child's growth and development, including performance in the classroom.

...Wing 2010). It is most often seen in nullparous and younger women and there appears to be a link with lower socioeconomic status, diabetes and sickle cell disease, although not with ethnicity (Hill et al 2005, Jolley et al 2012). It is more common in the 2nd and 3rd trimester (Archabald et al 2009, Hazhir 2007, Hill et al 2005) as the presence of urinary pathogens seems to increase as pregnancy advances (Hill et al 2005). There does appear to be an association between repeated urinary tract infections and sexual activity (Bernard et al 2011, Pfau and Sacks 1992). If not effectively treated, acute pyelonephritis may have serious consequences for both the mother and fetus. Urinary tract infections in pregnancy may lead to septic shock, anaemia, respiratory insufficiency, fluid balance disorders, renal scarring, acute kidney injury, chronic renal insufficiency and death (Hill et al 2005, Jolley and Wing 2010, Jolley et al 2012, Kumar et al 2009, Nwoko et al 2012, Vasquez and Vilar 2010).
