Why is it challenging to maintain or gain weight with HIV?
Managing weight with HIV can be tricky because you might experience either unintended weight loss or significant weight gain, depending on several factors.
Weight Loss Challenges:
Some people with HIV struggle to maintain or gain weight, which can put them at risk of becoming sick. Unintentional weight loss can be a concern for some individuals living with HIV.
Weight Gain After Treatment:
Interestingly, many people actually experience the opposite problem - gaining weight after starting HIV treatment. Research shows that people with HIV taking antiretroviral therapy (ART) can gain weight up to three times faster than people without HIV.
Why Weight Gain Happens:
Several factors contribute to weight changes:
- Certain ART medications are associated with weight gain as a side effect
- Immune system changes related to HIV may affect metabolism
- People with more immune activation or lower CD4 counts when starting treatment are more likely to gain weight
- As HIV treatments help people live longer, age-related weight gain becomes more common
- Other health conditions like heart disease or diabetes can affect weight
Risk Factors for Weight Gain:
Some groups experience more significant weight gain after starting treatment, including people who are assigned female at birth, less healthy when starting treatment, of lower socioeconomic status, or Black or of African descent.
Talk to your doctor about your specific weight concerns - they can help determine whether treatment adjustments or lifestyle changes might help.
