One cause of anemia is diet. This might include diets short of certain vitamins or minerals, such as iron, B12, or folic acid. Anemia also can be caused by bleeding or blood loss. Other causes of anemia may be related to chronic disease or treatments for kidney disease, cancer, or HIV infection. This type of anemia will not be corrected by itself or through dietary supplements.
Anemia can produce a wide range of symptoms.
But it can also cause dizziness, headaches, loss of sex drive, inability to concentrate, and shortness of breath. The symptoms of anemia can be so severe that some people can become bedridden, unable to work, or unable to perform even basic daily activities, like food shopping or taking the dog for a walk. If you're experiencing any of these symptoms, you may have anemia without even knowing it. This requires a sample of your blood. Do not push yourself to do more than you can do.
