Most bloating comes from gas building up in your gut or food moving through it slowly, and the usual drivers are what you eat, how fast you eat, and constipation.
Air you swallow while eating quickly, sipping carbonated drinks, or chewing gum adds to the gas already made when bacteria break down fiber and certain sugars. Beans, onions, broccoli, wheat, dairy, and sugar alcohols such as sorbitol and xylitol are frequent culprits. If you are constipated, stool sits in the colon and gas backs up behind it, so bloating often improves once bowel habits get regular. Repeated bloating tied to specific foods can point to lactose intolerance, celiac disease, or irritable bowel syndrome, all of which a clinician can test for. Slowing down at meals, walking after you eat, drinking water, and building fiber up gradually help most people.
How to beat the bloat
Common questions
why do i bloat
Bloating happens when gas builds up in your intestines or your gut muscles move food along more slowly than usual. Common triggers include swallowed air from eating fast, carbonated drinks, chewing gum, beans, onions, wheat, and sugar alcohols like sorbitol. Constipation backs up stool and traps gas behind it. Lactose intolerance, celiac disease, and irritable bowel syndrome cause repeated bloating tied to meals. Hormone shifts before a period add water retention. Track what you eat for two weeks, cut one suspected trigger at a time, walk after meals, and drink enough water. See a clinician for bloating with weight loss, blood in stool, vomiting, or belly swelling that does not go away.
