You should ask your doctor to check the amount of red blood cells in your body to find out if fatigue is caused by anemia. The red blood cells carry oxygen to all parts of your body. If you don't have enough red blood cells to deliver oxygen, you can feel fatigued. HIV, anti-HIV medications, a woman's period and other factors can cause anemia.

What You Can Do About Anemia:

* Have your red blood cell counts checked several times a year.

* Eat foods high in certain nutrients (iron, vitamin B12, and folic acid) such as fish, lean meats and poultry, spinach, asparagus and other dark leafy green vegetables.

* Talk to your doctor about treatments for anemia such as prescription drugs or a new HIV medication.
