Anemia, Type Not Specified (Adult)

Red blood cells carry oxygen to the tissues and organs of your body. Anemia is a condition in which your blood makes fewer than normal, healthy red blood cells. You need iron to make hemoglobin in red blood cells. Hemoglobin is the iron-rich protein that carries oxygen. Iron deficiency anemia is the type of anemia caused due to low-iron levels. It is the most common cause of anemia. Iron deficiency anemia may be caused by:

• Blood loss. This can be caused by heavy menstrual periods. It can also be caused by bleeding from the stomach or intestines.

• Major surgery or physical trauma

• Pregnancy

• Certain medicines or treatments, such as chemotherapy

• Not eating enough foods that contain iron.

Other causes of anemia include certain vitamin deficiencies, chronic kidney disease, genetic diseases, and other chronic illnesses.

Anemia makes you feel tired and run down. When anemia becomes severe, your skin becomes pale. You may feel short of breath or have chest pain during and after physical activity. Other symptoms include:

• Headaches

• Extreme fatigue and weakness

• Chest pain or shortness of breath

• Fast or irregular heartbeat

• Pounding or whooshing in your ears
