Introduction: Anemia


advertisement

Anemia: Anemia is a lack of red blood cells that thereby reduces the amount of oxygen the blood carries to the body. Symptoms for gradual onset of anemia include fatigue, weakness, and pallor and may be mild at first; see symptoms of anemia. Acute anemia such as from blood loss has more severe symptoms such as dizziness and unconsciousness. Anemia can be serious and any symptoms need prompt professional medical advice.

Anemia can result from various underlying conditions ranging from blood loss from various types of bleeding (menstruation, childbirth, gastrointestinal bleeding), to various conditions resulting in a lack of iron such as iron deficiency, malabsorption, or certain kidney diseases. There are also various medication causes of anemia.

Anemia: If your blood is low in red blood cells, you have anemia. Red blood cells carry oxygen (O2) to tissues and organs throughout your body and enable them to use the energy from food. Without oxygen, these tissues and organs--particularly the heart and brain--may not do their jobs as well as they should. For this reason, if you have anemia, you may tire easily and look pale. Anemia may also contribute to heart problems. 1
