The inability to eat in the advanced stage of AIDS is usually caused by physical exhaustion and psychological stress, and timely medical treatment is recommended. Patients in the advanced stage of AIDS will develop many kinds of serious infections and malignant tumors due to the extreme decline of body resistance, and slowly develop systemic organ failure. In this case, they should go to a specialized hospital as early as possible, and be given enteral or parenteral nutritional support, as well as treatment of complications, in order to fight for the opportunity to fight the virus and prolong their lives. In addition, the patient may also be under great psychological pressure while his body is failing. Family members and doctors can accompany and enlighten the patient more, so that he or she can reduce psychological pressure, maintain emotional stability, put down the burden of thought, and try to drink some easy-to-digest food such as rice soup, milk or soybean milk when hunger pangs appear.
