Patients over the age of 65 are more likely to develop oesophageal and gastric diseases, such as motility abnormalities, gastroesophageal reflux, reflux complications (such as Barrett's, dysplasia, and oesophageal cancer), gastric ulcers, and gastrointestinal bleeding. Lower GI issues such as pelvic floor abnormalities (including fecal incontinence), constipation, diarrheal illness, diverticular disease, inflammatory bowel disease, and colon cancer are also more common and atypical in the elderly. Malnutrition and obesity are major concerns among the elderly, who face unique dietary challenges.
