Anemia

Anemia

Anemia is a condition characterized by too little hemoglobin or too few red blood cells in the blood. It is considered a symptom of an underlying disease or condition rather than a disease itself. The most common causes of anemia are deficiencies of iron, vitamin B12 and folic acid. Anemia may also be caused by loss of blood through gastrointestinal bleeding; common causes are medications such as aspirin and ibuprofen, and cancer.

Two other forms anemia are hemolytic anemia, in which red blood cells are destroyed more quickly than normal; and sickle-cell anemia, in which the body produces abnormal hemoglobin. Anemia occurs when there is too little iron stored in the body. Young children and adults on restricted diets may not get enough iron in the foods they eat; this can lead to anemia.

The digestive system may not be able to absorb enough iron; this occurs most often when part of the stomach has been removed. A person may become anemic through excessive loss of blood; this can affect women with heavy menstrual periods, and people with a stomach ulcer, duodenal ulcer, hemorrhoids, or cancer of the stomach or large intestine.If you suspect that you have anemia, it's important to visit your doctor.

Anemia can weaken body's resistance to illness or injury, and limits your energy and productivity. It can also indicate a more serious medical condition. Anemia is confirmed through a blood test. Treatment for anemia may be iron supplements or injections.
