The symptoms of HIV infection are multiple and varied and can either be caused by the direct effect of HIV on the body or be a consequence of the complications of a severely damaged immune system. It is also worthwhile remembering that people with HIV can develop symptoms due to medical conditions that are entirely unrelated to HIV, and it is not always appropriate to assume that HIV is the cause of all symptoms.

The following list is not meant to be exhaustive but describes the most common HIV-related symptoms, their causes and what to do if they occur. If you are at all worried by any symptoms or problems you should always discuss them with your doctor.
