HIV and Weight Loss - Topic Overview

Weight loss in people with HIV has many possible causes. If you lose weight fast, it may be because you have another infection along with HIV. This type of illness is called an opportunistic infection.

Gradual weight loss may be due to problems with nutrition. You may lose weight if you can't eat enough food or if your body can't absorb all the nutrients from the food you eat.

Eating healthy

Eating a healthy, balanced diet with enough protein and calories may help you keep weight on. It also can help your immune system stay strong to fight infection.

Your doctor or a registered dietitian can help you make a plan that works for you.

Here are a few tips:

  • If you are sick to your stomach or don't feel like eating, discuss your medicines with your doctor. It may be possible to change medicines. Do not change medicines on your own. Always discuss changes in medicines with your doctor, and make those decisions together.
  • If you don't feel like eating, eat your favorite foods. Eat smaller meals several times a day instead of a few large ones.
  • Drink high-calorie protein shakes between meals. Try nutritious drinks, such as Ensure. Protein or energy bars are another good way to get extra calories between meals.
  • If you have diarrhea, eat bland foods like rice, bananas, or bread. Avoid high-fiber foods. Milk products can cause diarrhea for some people who react to the sugar or lactose in the milk. If you have this problem, try lactose-free or soy-based products.
  • If you have mouth sores, avoid spicy foods, hot or cold foods, oranges, grapefruit, and other citrus fruits. Stay away from hard or crunchy foods. Use a straw when you drink.
  • If you are sick to your stomach, try drinking peppermint or ginger tea.
