    Anemia is a lack of iron or a deficiency of oxygen carrying capacity in red blood cells. Iron deficient anemia is a result of inadequate supply of dietary iron. It can also be a result of blood loss, usually during heavy menstruation.

    Anemia is a condition in which your blood does not have enough red blood cells. Red blood cells carry oxygen to your body organs to help them use energy. If you don’t have enough red blood cells, your organs may not work as well as they should. This may make you look pale and feel tired, or you may not have any noticeable symptoms right away.

    Anemia is a condition in which the blood is deficient in red blood cells or the hemoglobin (iron-containing) portion of red blood cells. As noted, the primary function of the red blood cells (RBCs) is to transport oxygen from the lungs to the tissues of the body in exchange for carbon dioxide. The symptoms of anemia, such as extreme fatigue, reflect a lack of oxygen being delivered to tissues and a buildup of carbon dioxide.

    Anemia is a decrease in the amount of oxygen-carrying substance (hemoglobin) found in red blood cells. Anemia causes weakness, pale skin, and general tiredness (fatigue).

    Anemia can be caused by blood loss or bleeding, an increase in the destruction of red blood cells, or a decrease in the production of red blood cells. Types of anemia include iron deficiency anemia, folic acid deficiency anemia, and vitamin B12 deficiency anemia, among others. Each type of anemia is treated differently.

  • Anemia is a condition in which the number of red blood cells, the amount of hemoglobin (a part of the red blood cell), or the total volume of blood is less than normal, resulting in less oxygen being carried to the body's cells. Anemia can be caused by chronic kidney disease, low iron or folate levels, or bleeding problems. Anemia causes a feeling of extreme fatigue.
