Aging and Digestion: What Changes and How to Feel Better

As people age, the GI tract can slow and nerves/muscles may misfire, leading to more reflux, slower stomach emptying, thinner stomach lining, and greater susceptibility to gastritis or ulcers. Small-bowel and colon motility can worsen, increasing bloating, diarrhea, or constipation, and many medications add GI side effects. Practical tips include chewing thoroughly (15–20 times per bite), boosting plant-based fiber and hydration, staying active after meals, prioritizing 7–9 hours of sleep, and reviewing medications with a doctor. If persistent or alarming symptoms (trouble swallowing, weight loss, blood in stool, or vomiting), consult a gastroenterologist for tests like bloodwork, endoscopy, or colonoscopy.
