Elderly people who have difficulty in eating may have herpes stomatitis, esophageal cancer, Alzheimer’s disease and other conditions. 1. Herpetic stomatitis: the weak immunity of the elderly may lead to herpetic stomatitis after infection with herpes virus, which is characterized by the appearance of a large number of small blisters on the mucous membrane of the oral cavity, making it difficult to eat. 2. Esophageal cancer: Difficulty in swallowing is a typical symptom of esophageal cancer, and the proliferating cancer cells will block the esophagus, making it difficult to swallow food. Generally speaking, CT, barium esophagus meal and endoscopy can be taken to confirm the diagnosis. 3. Alzheimer’s disease: Alzheimer’s disease may cause cognitive decline and concentration disorder, which may lead to eating difficulty without eating consciousness, usually appearing in the middle and late stages of Alzheimer’s disease. There may be other reasons for elderly people to have difficulty in eating, so you can go to the hospital to complete the relevant examinations to clarify the situation.
