Sickle Cell Anemia Essay

Anemia is a condition where the number and quality of erythrocytes in the blood decreases. There are several factors that may prompt anemia: blood loss, complications in erythrocyte production, increased erythrocyte destruction, or a combination of these. There are different types of anemia, and they are distinguished by size, shape, or the erythrocyte’s substance.

There are several different types of anemia. Some of those are hemorrhagic, iron-deficiency, aplastic, and pernicious. Pernicious anemia is a type of anemia due to a vitamin B-12 deficiency and

The most prominent cause of Iron Deficiency Anemia is bleeding. Blood loss from the Gastrointestinal Tract is a significant cause of anemia for both men and women. When blood is present in excrement, a gastrointestinal problem exists. Many times, people are unaware of these problems with their waste products. When they begin to feel the symptoms of anemia and undergo tests that determine that they are anemic, it begins the process of discovering more health problems. Anemia can serve as the precursor of certain diseases. There are many instances when it is merely a sign of severe disease such as a peptic ulcer disease, gastritis, hemorrhoids, angiodysplasis of the colon, and colonic adenocarcinoma (http://www.physsportsmed.com/issues/sep_96/browne.htm).

Iron deficiency anemia, one of the most common types of anemia, is a blood disorder where

Then anemia as previously meantioned kills red blood cells. Causing a veriaty of different trouble across the board with the body, along with substanial fatigue. This type of anemia is called low iron-anemia, which goes along with its cause. for this reason it is obvious to see why doctors and scientist believe that iron defiecency is one of the causes for lupus. Low iron enemia as well as chronic enemia wich is passed down through heretity is also suspected to be one of the reasons for lupus.

People with sickle-cell anemia have to take penicillin, get extra vaccines, and get many tests done. Like most people they need to also exercise every day, have a nourishing diet, and get enough sleep every night. Sickle-cell anemia is most common in African Americans, 1 out of 365 African American children are born with two mutated hemoglobin genes or sickle-cell anemia. Sickle-cell anemia is a negative mutation of the hemoglobin gene because it prevents the oxygen from the lungs to the places its needed through the

* Anemia-related fatigue occurs when there is a decrease in red blood cells (RBCs). This happens when myeloma cells replace RBCs in the bone marrow.

Conferring to the case study 1 of Ms. A, who is suffering from iron deficiency anemia. “People who experience iron deficiency anemia lack adequate iron required to produce hemoglobin. Hemoglobin supports red blood cells in carrying oxygen all through the body” (Mayo Clinic, 2014). In this presentation, the writer will provide rationales where Ms. A is presenting signs and symptoms of Iron Deficiency Anemia.

Anemia is a condition in which the concentration of red blood cells or hemoglobin in the blood is below normal. Hemoglobin is a substance in red blood cells that carries oxygen to the tissues of the body. Anemia results in not enough oxygen reaching these tissues.

Your doctor will look for symptoms of anemia and other physical clues that might point to a cause. There are basically three different causes of anemia: blood loss, decreased or faulty red blood cell production, or destruction of red blood cells Complete blood count (CBC), which determines the number, size, volume, and hemoglobin content of red blood cells . Blood iron level and your serum ferritin level, the best indicators of your body's total iron stores . Levels of vitamin B12 and folate, vitamins necessary for red blood cell production . Special blood tests to detect rare causes of anemia, such as an immune attack on your red blood cells, red blood cell fragility, and defects of enzymes, hemoglobin, and clotting Reticulocyte count, bilirubin, and other blood and urine tests to determine how quickly your blood cells are being made or if you have a hemolytic anemia, where your red blood cells .Only in rare cases will a doctor need to remove a sample of bone marrow to determine the cause of your anemia.Medical professionals use medication,therapy, surgery, and

According to the American Society of Hematology, approximately 35 million people in the United States are over the age of 65, and almost 10 percent of this population is currently anemic. Anemia occurs when red blood cell counts drop, or when red blood cells do not contain enough hemoglobin. In chapter seven of Biology Today and Tomorrow without Psychology, we learned hemoglobin is an oxygen-binding protein in red blood cells that consists of four polypeptides (2-alpha globins & 2-beta globins). Each globin holds a cofactor called a heme, and each heme has an iron

Ms. A. a 26-year-old white woman had been experiencing increased shortness of breath, low energy levels and these symptoms got worse during her menstruation periods. She had also been experiencing Menorrhagia and dysmenorrheal for the last 10-12 years. There is a possibility that Ms. A could be suffering from anemia. Moreover, on the day she was taken to the emergency clinic, she experienced light-headedness the attending physician’s notes indicated a temp of 98 degrees F, an elevated heart rate and respiratory rate, and low blood pressure. According to a study done by Ilyas , et al. (2012 ), Iron deficiency (ID) is majorly responsible for the cause of nutritional anemia. Specifically Menorrhagia responsible for loss of more than 80 mL during the menstrual periods is the most common cause of anemia in young women. Consequently, anemia commonly causes reduction of oxygen movement in the blood, causing fatigue and a diminished physical capacity. In addition, even moderate anemia can bring about shortness of breath, rapid heart rate, lightheadedness as well headaches.

Anemia is the medical condition that results from blood not carrying enough oxygen to the body through the blood. It is sometimes caused by a loss in the percentage of red blood cells in the blood. While nearly one in five seniors have anemia, the condition is the result of other medical issues and not age. The most common reason for anemia in seniors is a lack of Vitamin B12. Other reasons include a folate deficiency or gastrointestinal bleeding.

In this type of anemia, heme synthesis is decreased, renal production and/or response to erythropoietin is decreased, liver synthesis of hepcidin is increased and serum ferritin is increased (in contrast to iron deficiency anemia, in which serum ferritin is low). Chronic severe anemia (e.g., hemoglobin less than 5 g/dL) is a risk factor for high-output heart failure, in which cardiac output is high, but still insufficient to meet metabolic demands of the body.

Iron deficiency anemia is quite common in children, as iron is needed to support growth. A lack of iron in the diet can cause delays in brain development, which may be irreversible. Common symptoms of iron deficiency anemia include irritability, palor, weakness, and cold hands and feet. Prevention of anemia is crucial for expectant mothers, as anemic women are at a higher risk for delivery complications such as hemorrhaging and having infants of low-birth weight. (Frantz, C. 2010).
