What cause of weight loss in CKD and HIV/AIDS can be attributed to painful sores?

Weight loss in patients with Chronic Kidney Disease (CKD) and HIV/AIDS can often be attributed to a reduction in food intake, particularly in the context of painful sores. These sores, which may appear in the mouth or throat, can make chewing and swallowing difficult and uncomfortable. As a result, individuals may avoid eating normal meals or certain foods altogether to reduce pain, leading to decreased caloric and nutrient intake.

This change in dietary habits can catalyze a cascade of negative effects, including unintentional weight loss and malnutrition, which is particularly concerning for patients with CKD and HIV/AIDS, as both conditions increase nutritional needs and can exacerbate health issues. While other factors like mental health issues, diarrhea, and fat malabsorption can also contribute to weight loss, in this specific context, the direct impact of painful sores on food consumption makes the reduction of food intake the primary cause of weight loss.
