Health Desk. Lack of blood in the body, called anemia, is often ignored, but it can pose a serious threat to health. When the amount of red blood cells (RBC) or hemoglobin in the body decreases, sufficient oxygen cannot reach the organs. This may result in increased risk of many serious diseases.
1. Iron deficiency anemia
This is the most common type of anemia, which occurs due to iron deficiency in the body. Its symptoms include extreme fatigue, weakness, irritability and difficulty concentrating.
2. Aplastic anemia
Aplastic anemia is a rare but serious condition in which the bone marrow stops making enough blood cells. This increases the risk of infection and bleeding in the body can become uncontrolled.
3. Sickle cell anemia
Sickle cell anemia is a genetic disease in which red blood cells take a sickle-like shape. These abnormal cells can obstruct blood flow, causing damage to organs and severe pain.
4. Thalassemia
Thalassemia is also a hereditary disorder in which the body is unable to produce enough hemoglobin. In severe cases, patients may require regular blood transfusions throughout their lives.
5. Heart related problems
Lack of blood also affects the heart. If the heart does not get sufficient amount of oxygen, it has to work harder. This can cause abnormal heartbeats (arrhythmia), heart enlargement, and an increased risk of heart failure in the long run.
