Symptoms and Signs of Anemia

Doctor's Notes on Anemia

Anemia refers to a medical condition in which the red blood cell count or hemoglobin level is less than normal. Anemia can be caused by different medical conditions and is always related to either decreased production of red blood cells or hemoglobin, or an increase in loss or destruction of red blood cells. Iron deficiency anemia is a very common type of anemia and occurs as a result of chronic blood loss for any reason, which depletes the body’s iron stores.

Some people with anemia, especially mild cases of anemia, may not have any symptoms. When symptoms do occur, the most common symptoms are tiredness, fatigue, pale appearance to the skin, shortness of breath, and heart palpitations. Other associated signs and symptoms in some people can include hair loss and worsening of heart problems.
