The phenomenon of bedridden elderly people not eating is mostly due to prolonged bed rest resulting in reduced gastrointestinal motility. Hot towels can be given to repeatedly rub the abdomen to enhance gastrointestinal motility to promote digestive function. At the same time, food such as rice, meat, vegetables and fruits can be blended into a paste with a blender, which is easier to swallow and digest and absorb, and can also ensure nutritional intake. In addition, for elderly people who are unable to eat in the short term due to illness, they can be given a nasogastric tube or nasogastric tube to assist them in eating, and injected with drugs to promote digestion and other treatments through the gastric tube, and then remove the gastric tube or nasogastric tube after the physical illness of the elderly is cured so that they can resume normal eating. Other elderly people who cannot eat through the digestive tract, such as bedridden patients in coma and gastrointestinal tumors, can be given intravenous amino acids, glucose, albumin and other nutritional solutions to supplement their energy.
