AIDS-related wasting syndrome (AWS)
Changes in body composition during weight loss
like starvation or marasmus
Weight loss or wasting even with adequate or
increased kcal intake, may be immune mediated
Decrease in LBM even without weight loss
Nutrition Therapy
Nutritional Implications
Reduction in muscular protein influenced by medications
Changes in macro- and micronutrient status
Lower serum selenium, zinc, magnesium, calcium, iron,
manganese, copper, carotene, choline, glutathione, vitamins A,
B6, B12, E
Nutrition Therapy
Nutritional Implications
