RESUMO
HIV affects almost all bodily systems, which can lead to recurrent opportunistic infections, weight loss, distribution of weight changes, and death. Malnutrition and wasting, two symptoms that interfere with nutrient availability, accessibility, and metabolism, are associated with higher morbidity and mortality. Nausea, vomiting, swallowing or chewing difficulties, or the response of the body to opportunistic infections or medications that are considered vital to the treatment of the disease may affect nutritional status. A positive nutritional balance may help to improve the immune and other body systems, and delay the progression of the disease, This article reviews the effect of the nutritional status on the physiologic changes in the person who is infected with HIV.
