What does unintentional weight loss feel like with HIV infection?

The change may be subtle, with looser clothes, reduced strength, or tiredness becoming noticeable before the scale is checked. HIV infection can affect appetite and the body’s response to illness; mouth or swallowing problems, diarrhoea, nausea, and other infections can also make eating difficult. Some people have no obvious symptoms for a long time, so how weight loss feels cannot identify HIV infection.

Many conditions and medicines can cause unintentional weight loss. If HIV exposure is a concern, testing is the way to assess it rather than trying to interpret symptoms.

Arrange medical care for ongoing unexplained weight loss, especially with fever, night sweats, persistent diarrhoea, swollen glands, recurrent infections, or mouth problems. Ask about an HIV test if there has been a possible exposure; confidential testing and treatment can be discussed with a clinician. Record appetite, bowel symptoms, fevers, medicines, and weight changes. Keep fluids up and choose manageable foods while awaiting assessment.

Seek urgent help for severe dehydration, confusion, fainting, breathing difficulty, severe weakness, inability to swallow fluids, or rapidly worsening illness. Contact a clinician promptly if weight continues to fall, diarrhoea persists, fever does not settle, or infections keep returning. Early assessment can identify treatable causes and guide appropriate support.

Could an HIV test be appropriate for me? What other causes of weight loss should we check? Do my fever, bowel, or mouth symptoms need assessment? How can I protect nutrition and hydration while waiting for results?
