Loss of weight either suddenly, over a short period of time or progressively over many months is a common problem and of particular concern in persons with symptomatic HIV disease.

Causes

Opportunistic infections (especially MAI), diarrhoea, anorexia, mouth problems, depression and anxiety can all contribute. A more specific cause is the direct effect of HIV on the gut and increased energy requirements needed by the body to fight infection.

What to do

Dealing with or preventing weight loss is an important aspect of general treatment of HIV disease. Specific problems such as diarrhoea, acute and chronic infections and nausea should be investigated and treated. Medical advice and help from a dietician should be sought and supplementary measures such as high calorie drinks, vitamins and appetite stimulants may be of help.
