Common changes, and practical ways to stay comfortable.
Quick answer
After 50, digestion often slows: the gut moves food more slowly, constipation becomes more common, the body may produce less stomach acid, the gut microbiome becomes less diverse, and many people take medicines such as pain relievers, iron, calcium channel blockers or antidepressants that affect digestion. Helpful habits include eating 21 to 30 grams of fiber a day, drinking enough fluids, staying active, eating smaller meals, keeping a regular routine and reviewing medicines with your doctor. Colorectal cancer screening is recommended from age 45, and changes such as blood in the stool, weight loss or a lasting change in bowel habits should always be checked.
