Weight loss Weight loss, or wasting, is one of the commonest symptoms of HIV infection, and can occur at any stage of infection. It needs to be taken seriously because unintentional loss of weight is often a sign that you may have an active HIV-related infection or disease.
Malnutrition can also reduce the effectiveness of the immune system.
Causes of weight loss Weight loss occurs when the body is using up more nutrients than it is absorbing from food. The most important ways to prevent weight loss are to treat HIV-related infections promptly, and to ensure that your nutritional intake is adequate. It is much easier to prevent weight loss in the first place, rather than to try to regain it afterwards. It is sensible to arrange to see an NHS dietitian soon after you are diagnosed HIV-positive, rather than to delay until you have already started to lose weight. A dietician can help you look at your diet to ensure that you have an adequate intake of all the main types of nutrients, and recommend any changes to fit in with any drugs you are taking and to help you cope with problems such as nausea.
