The Relationship Between Anemia and Nutritional Issues
INTRODUCTION
"Anemia can be defined as a decrease in the oxygen-carrying capacity of the blood caused by low hemoglobin concentration" ("A Practical Guide", 1). "Cells in the body require oxygen to fully utilize fuels. The oxygen is transported from the lungs to tissues throughout the body via red blood cells. Oxygen binds to hemoglobin, a specific molecule within each red blood cell. This molecule consists of heme, which is a red pigment, and globin, which is a protein. If the amount of functioning hemoglobin is reduced, a condition known as anemia arises" ("Anemia", 1). "The anemia that may result can take many forms, including that caused by a low iron level (iron deficiency anemia), a vitamin deficiency (megaloblastic anemia), a thyroid deficiency, the premature destruction of red blood cells (hemolytic anemia), replacement of normal bone marrow cells by cancer cells or leukemia (myelophthisic anemia), injury to bone marrow (aplastic anemia), and inborn structural defect in red blood cells (e.g. sickle-cell anemia), inhibition of erythropoietin production by the immune system (anemia of chronic disease), and a normal or high iron level but an inability to manufacture hemoglobin or make use of the iron (sideroblastic anemia)" ("Anemia", 2). There are also several other less common types of anemia including: aplastic anemia, Thalassemia, acquired hemolytic anemia, inherited hemolytic anemia, sickle cell anemia, and anemia caused by miscellaneous factors ("Anemia", 3-4). All of these different types of anemia can be grouped into categories according to their causes and treatments. "In all, more than 400 different forms of anemia have been identified, man...

Malnutrition is common in haemodialysis patients due to specific characteristics of chronic renal insufficiency such as insufficient filtration ability and accelerated protein degradation. A deteriorated nutritional condition threats chronic dialysis patients lowered mobility and poor outcome include increased mortality (Carrero et al., 2013; Locatelli et al., 2002; Vannini, Antunes, Caramori, Martin, & Barretti, 2009). Thus there are several malnutrition indicators of haemodialysis patients were proposed such as SGA, GNRI and albumin level. Nevertheless, detection rate of each indicators seems to differ to each other (Pifer et al., 2002) and consideration of particular characteristics of haemodialysis patients is required for the practical apply. Hence, use of sensitive identifying assessment method and early intervention on malnourished patients are quite meaningful.
Thalassemia is an inherited blood disorder characterized by low amounts of hemoglobin and a low count of erythrocytes in the body. Thalassemia is caused by mutations in the deoxyribonucleic acid of cells, which makes hemoglobin. The mutations are passed from parent to child. The mutations vary depending on the type of Thalassemia inherited. The variation in the mutation occurs from the number of gene mutations, which are inherited, as well as mutation within the hemoglobin molecule. Clinical manifestations are diverse ranging from asymptomatic, to those who are carriers of the thalassemia, which may have mild symptoms, there also people who posses the trait, who may have severe symptoms which lead to death.
Sickle-cell anemia is a genetic disorder that makes your body produce red blood cells that are abnormal in shape. This disease is also widely known as hemoglobin SS disease. Unlike normal red blood cells, sickle cells are rigid and tenacious. Due to their shape and rigidness, they can block blood flow. In turn, this could cause organ damage to the body. Sickle cells are also fragile and die very easily due to the fact sickle cells have a lifespan of twenty days instead of the normal one hundred and twenty days for normal red blood cells.This causes the body to have a lower blood cell count, hence the name anemia in sickle cell anemia.
Thalassemia also known as Cooley’s anemia (Catlin 2003) was originally described by Thomas Cooley in 1925 (Starr 2012). The name Thalassemia came from the Greek name for sea (thalassa). This was due to the fact that for many years, those who had been most affected lived in the vicinity of the Mediterranean Sea (Starr 2012). Beta thalassemia occurs most frequently in people from Mediterranean countries, North Africa, the Middle East, India, Central Asia, and Southeast Asia. Thalassemia is a genetic blood disorder that is inherited from parents. The absence or reduction in the production of hemoglobin is the cause of thalassemia. Hemoglobin is in the red blood cells, it is a protein that carries oxygen to cells throughout the body (Catlin 2011)). Thalassemia is characterized by quantitative defects in the synthesis of either the alpha hemoglobin for Alpha Thalassemia or the beta hemoglobin for Beta Thalassemia (Starr, 2012). It is not widely known how many people are affected by Thalassemia but the US populatio...
According to the details given in case study, Ms. A has iron deficiency anemia. Iron deficiency anemia is the most common type of anemia. It is a condition where the blood lacks enough red blood cells (Clark, 2008). When there are a low number of red blood cells, it makes transportation of oxygen to parts of the body very difficult. Iron deficiency is type of anemia due to the lack of iron in the body. Without the proper amount of iron in the body, it cannot produce enough hemoglobin and since hemoglobin is the main carrier of oxygen, low levels of it can lead to tiredness and shortness of breath (Copstead, Banasik, 2010).
A patient with sickle cell has inherited the condition from both parents, and it all starts in the hemoglobin. Hemoglobin is “an iron-containing protein in red blood cells that reversibly binds to oxygen” (Reece, Urry, Cain, Wasserman, Minorsky, & Jackson, 2011). Obviously, hemoglobin is an important substance for oxygen to be transported in red blood cells. However, a patient with sickle cell has irregular hemoglobin cause by inherited genes. This “oxygen delivery” system cannot function properly because a gene
Education plays a dominant role in the lives of students all over the United States. Since most students spend roughly eight to twelve hours in school, it is important to make sure that they are provided with a healthy and nutritious breakfast, lunch and snack.
Anemia is a disease that is commonly seen in veterinary medicine. This disease can be described as having low amounts of red blood cells and a reduced amount of hemoglobin in the circulating blood, which reduces the oxygen-carrying capacity of the blood. It develops from loss, destruction or lack of production of red blood cells. Anemia is usually a secondary disease caused by another disease or medical condition. There are three different types of anemia; regenerative, non-regenerative and relative.
Thalassemia is basically a name for similar groups of inherited blood diseases that involve missing or abnormal genes regarding the protein in hemoglobin which is the red blood cells that carry oxygen throughout the body. I will discuss the different types of Thalassemia, how Thalassemia is diagnosed, and the treatments available. I will also discuss the complications and side effects of the treatments, the disease’s causes and effects, and how it is more dominant in some parts of the world than others. Thalassemia is a blood disorder which means the body makes fewer healthy red blood cells and less hemoglobin. Hemoglobin is a protein that carries oxygen throughout the body and having less hemoglobin leads to anemia. Alpha globin and beta globin are the proteins that create Hemoglobin. A defect in the gene that helps control production of alpha or beta goblin leads to Thalassemia. Fewer blood cells leads to anemia, which is the common culprit in Thalassemia.
..., non-heme iron will be the prime source of iron implicated in her diet, which has been discovered to be a less absorbing iron found in plant-based sources than in comparison to heme iron, which is predominantly found in animal products. In order to effectively enhance the absorption of non-heme iron, adequate intake of vitamin C needs to be initiated within her diet. Zinc and iron must not be consumed in excess of each other in order to prevent deficiencies of either due to their counteracting mechanisms; however, it is not a major problem in vegan diets due to its rare incidence. Although Jenny Brown does not initiate supplements in her diet, Jenny can still receive adequate nutritional benefits that are essential for her health by consuming a variety of plant-based sources and following the recommended requirements of nutritional intakes, according to her status.

Since we have been learning about nutrition in class, our task was to record a food log. Nutrition requires a well-balanced diet containing nutrient and vitamins like amino acids and fatty acids. Over the past seven days I have been recording and have been looking very carefully at my intake of nutrients, minerals, vitamins, and fats. In our task, the objective was to record the basic foods we ate during the period of seven, but it did not require recording every single detail or our intake of food. Doing this food log was a pain and it was disturbing because I never wrote about what I ate like breakfast, lunch, dinner, or additional meals. I found this food log useful because it helped me learn what I can change in my intake of foods to make my diet healthy and to see what about my diet is affecting me from being healthy because I could affect me in the future.
Thalassemia is a blood disorder transferred through families. It occurs when the body makes less hemoglobin than needed or an unusual form of hemoglobin. Hemoglobin is the protein in red blood cells that carry oxygen. The disorder makes an excessive amount of destruction of red blood cells. This eventually leads to anemia.
Proper nutrition is one of the most essential elements to being healthy and living a long life. People deal with food every day, and food has been a part of life since the beginning of civilization. What we eat becomes our diet, and our diet plays a major role in deciding how healthy we are and how well our body functions. Without proper diet, our body cannot carry out the functions it needs to perform. Most people have some common knowledge on what is good and what is bad for the human body to consume. Fruits, vegetables, nuts, and grains are some common items people think of when they think of healthy foods. However, it is not enough just to know what foods are good for your body, it is also important to understand why certain foods are good for you and what they do to help the body function.
