In the late stages of the disease, AIDS patients often suffer from generalized malnutrition due to multiple secondary infections, and patients may exhibit weight loss of more than 10 percent. Therefore, the treatment and care of patients in this period is very important. In the late stage of AIDS, the patient’s diet should be strengthened, for example, the intake of protein and vitamins should be increased, and the content of meat, eggs and dairy products in food should be increased. Since the patient’s digestive function is relatively poorer due to secondary infection, he should be given easy-to-digest food and eat as few and as many meals as possible. The patient should take appropriate exercise, such as walking, slow walking, to avoid prolonged bed rest, which may lead to lung infections and bedsores, and so on.
