Anemia or anemia is a condition in which blood oxygen is reduced due to low hematocrit or low concentrations of hemoglobin in the blood. Usually, the blood contains a lower than normal number of red blood cells. Anemia occurs when there are not enough red blood cells in the body, this can happen by decreasing the production of red blood cells and bleeding also leads to the loss or destruction of blood cells. It is generally classified as chronic (long-term) or acute (sudden). Chronic anemia occurs over a long period of time and acute anemia occurs quickly. Generally, there are three types of anemia classified according to red blood cell volume. If the blood cells are smaller than normal then they are called microcytic, if the blood cells are of normal size then they are called normocytic and finally if the red blood cells are larger than normal then they are called macrocytic. At first, anemia may be very mild and go unnoticed, but symptoms get worse as the anemia gets worse. Signs such as fatigue, fainting, weakness, shortness of breath, chest pain lead to anemia. There are over 400 identified types of anemia and most of them are very rare. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”?

Iron deficiency anemia (IDA) affects many people around the world and has very harmful effects on those who suffer from this deficiency, which leads to a decrease in oxygen carrying capacity. Iron is very important for our body and is the component of hemoglobin and essential for its proper functioning. It plays an important role in many metabolic processes and can produce hemoglobin, a protein that helps red blood cells deliver oxygen throughout the body. This deficiency has visible symptoms such as fatigue, depression, hair loss, frequent headaches, brittle nails and can occur with blood loss due to menstrual periods and blood loss due to gastrointestinal bleeding. Of course, there are other causes than diet, notably for vegan people, infections, pregnancy. Diagnosis of iron deficiency anemia is made by a test called a complete blood count (CBC) which looks for the size and color of red blood cells, hematocrit, hemoglobin and ferritin. Additionally, there is another type of anemia called sickle cell disease. disease and is an inherited disorder of hemoglobin in the blood. Sickle cell disease is an anemia resulting from the production of an abnormal form of hemoglobin that causes red blood cells to become sickle-shaped at low oxygen levels. In 1949, Linus Pauling discovered adult hemoglobin HbA composed of four polypeptide chains 2-a and 2-ß, intended for physiological people in relation to people suffering from sickle cell anemia. The difference is at the 6-amino acid of the β polypeptide chain when glutamic acid is replaced by valine [glu -> val] due to the point mutation [GAG -> GTG]. The resulting hemoglobin produced by the ßs gene is called HbS. This leads to a change in the configuration of hemoglobin, as well as a change in the shape of erythrocytes, which, in conditions of lack of oxygen, take on the characteristic sickle-shaped shape. Sickle cells block the normal flow of blood through capillary vessels, causing..
