Elderly people with poor appetite should eat less and more meals and supplement with easily digestible and absorbable foods, such as millet porridge, barley porridge, noodles, steamed buns, bread, steamed eggs, fish soup, chicken soup, etc. You can also use enzyme supplement medications, such as compound digestive enzymes and Mitragynine pancreatic enzyme tablets, to help the elderly supplement digestive enzymes and promote the digestion of food. Finally, gastric motility drugs such as Mosapride, morpholine, Itopride, etc. can be taken. If the elderly eat very little, they can solve the problem of eating by inserting a gastric tube or jejunal nutrition tube. Intravenous supplementation such as amino acids, glucose, albumin, fat milk, vitamins, etc. can also be given. The cause of poor appetite in the elderly should be clarified, such as infectious diseases or diseases of the stomach itself, such as gastric ulcer, gastritis, gastrointestinal tumor, etc. The clarification of the cause is very important.
