Anemia is a disease caused due to the lack of red blood cells or RBC in the blood of a human body. Red blood cells carry oxygen to the various parts of the body and thus are the vital part in blood. The common symptoms of anemia are tiredness, pale skin and dizziness. These symptoms did not become clear until the condition gets worse and the only way to detect this disease is through blood test.
- Deficiency of Vitamin B12– Vitamin B12 directly impacts the production of hemoglobin and thus lack of Vitamin B12 in a human’s diet can lead to anemia. Vitamin B12 is mainly found in non vegetarian food so the chances of its deficiency in vegetarian are more in compare to non vegetarians. The deficiency of vitamin B12 can also be due to the lack of ability of absorbing Vitamin B12 from stomach’s wall. Anemia due to the deficiency of vitamin B12 is more common in people having diabetic problem, person suffering from thyroid and ages more than 40.
- Deficiency of Iron– The daily iron requirement of body to produce optimum amount of hemoglobin is 1mg which if not met can lead to anemia. The reason behind deficiency of iron can be improper diet and it usually happens in women who are menstruating heavily. The other reasons which can lead to deficiency of iron are hemorrhoids, ulcer, chronic ulcer and chronic bleeding of gums.
- Hemolysis – It happens when red blood vessels starts to break because of toxin, poison or immune reaction.
- Blood Loss– Blood loss is common in women who are heavily menstruating and can leads to anemia if proper care is not taken.
- Reduction in cell production by Bone marrow– Bone marrow is a soft and fatty tissue which is found inside the bones of body. In case due to any reason bone marrow malfunctions or becomes defective than it can lead to abnormality in the production of mature blood cells thus resulting in less production of red blood cells or increase in the loss of red blood cells in the body.
- Cancer Therapy– The treatment procedure like chemotherapy used in curing cancer effects the production of red blood cells of bones which decreases the oxygen carrying capacity resulting in anemia.
- Excessive intake of alcohol– Excessive intake of alcohol can lead to deficiency of vitamin in the body and the person ends up with Anemia. Alcohol is a stimulant thus it is recommended that men should not take more than two drinks a day and one drink a day for women.
- Smoking–It is worldwide known that Smoking causes the reduction of oxygen levels in blood cells and also cause blockage in the absorption of vital nutrients like vitamin c and folate acid which increases the risk of anemia caused due to the deficiency of vitamin.
- Kidney Diseases– Erythropoietin is a hormone released by kidney which helps in the production of red blood cells. The body of a person who is suffering from chronic kidney disease release less amount of erythropoietin which in turn reduces the production of red blood cells thus causing anemia.
- Chronic Diseases– Anemia can also be caused to a person who is suffering from any type of chronic disease. Science has not yet uncovered the exact mechanism but it is been medically proven that any prolong medical condition can lead to Anemia.
There are several other less common causes which lead to anemia. These causes are parasitic infections, insecticide exposure, lead poisoning, liver diseases, autoimmune diseases, AIDS, malaria, viral hepatitis.
