- Anemia - when you do not have enough blood
anemia - a condition characterized by low levels of hemoglobin and red blood cells.There are several types of anemia, each of which has its reasons.Anemia can be temporary or chronic, and proceed in various ways, from mild to severe.
Symptoms Symptoms and signs of anemia may vary depending on the reasons, but most often it is accompanied by symptoms:
- Fatigue, lethargy, pallor
- Fast and / or irregular pulse
- Dyspnea Dizziness
- Problems with thinking
- Cold hands and feet
Usually anemia occurs first very mild and hardly noticeable.However, as the disease progresses the patient's condition may be exacerbated.
Consult your doctor if you often feel tired for no apparent reason, since anemia may be a sign of serious illness.
Lack of red blood cells in the blood can be, if the body does not produce red blood cells in sufficient amounts, resulting in a large blood
The red blood cells contain hemoglobin - iron-rich protein in red, by which red blood cells are supplying oxygen to the various tissues of the body.It also transports the carbon dioxide to the lungs, whereupon it is excreted.
Red blood cells are constantly produced in the bone marrow, located in cavities of large bones.To produce hemoglobin and red blood cells, the body needs iron, vitamin B12, folic acid Folic acid - the value is difficult to overestimate and many other nutrients.
most common causes of anemia:
- iron deficiency.If the organism is lacking in iron, bone marrow can not produce enough red blood cells and hemoglobin, resulting in anemia.
- vitamin deficiency can also cause anemia, even with adequate iron intake.The body of some people can not extract vitamins from food in sufficient quantities and it also causes anemia, and it can not be managed only by a change in diet.
- chronic diseases.Some chronic diseases, such as cancer, HIV and AIDS, rheumatoid arthritis Arthritis - a variety of forms and complications , Crohn's disease can disrupt the production of red blood cells.
- Aplastic anemia - a rare, life-threatening condition in which the production of red blood cells and hemoglobin is broken due to an infection, medication or certain autoimmune diseases.
- bone marrow disease.Various diseases, such as leukemia and myelodysplasia can cause anemia, since they affect the bone marrow.Other types of cancer, such as multiple myeloma, myeloproliferative disorders and lymphoma, less often, but can also become a cause of anemia.
- Hemolytic anemia.Violations related to this group, develop when red blood cells are destroyed faster than the bone marrow time to produce them.Some blood diseases may accelerate the destruction of red blood cells.Hemolytic anemia can be hereditary and develop at an early age;however, it can occur and lifelong.
- Sickle cell anemia.This innate and sometimes dangerous form of anemia caused by a defective form of hemoglobin that causes red blood cells to make them not peculiar shape of sickle or crescent.These abnormal erythrocytes live less than healthy cells and because of this level of red blood cells is reduced.
Factors that increase the risk of anemia:
- Malnutrition.As discussed above, anemia is caused by lack in the diet of certain nutrients.
- Disorders of bowel How to organize the work of the intestine - a phased process can impair the absorption of nutrients.These disorders include, for example, celiac disease Celiac - not quite intestinal pathology and Crohn's disease;removing portions of the small intestine is surgically can have the same effect.
- menstruation.As a rule, women before menopause, the risk of developing anemia is higher than in men.
- pregnancy is associated with an increased risk of anemia due to the increased volume of blood in the body and because of the fact that iron is now necessary not only the woman but also her unborn child.
Other factors, such as drug therapy, exposure to chemicals and stress also increase the risk of anemia.
