On this page 4 sections ## Common causes of bloating - Eating too fast, fizzy drinks and chewing gum increase swallowed air. - IBS and food intolerances are common causes of bloating. - Constipation often causes bloating that eases after a bowel movement. - Persistent bloating in women may rarely signal ovarian cancer — do not ignore ongoing symptoms. - Probiotics help some people with bloating, but the evidence varies. ## What is bloating? Bloating is a feeling of fullness, tightness or visible swelling in the abdomen. It is extremely common and usually not serious, though it can be uncomfortable and affect confidence. Understanding triggers helps most people manage symptoms effectively without unnecessary tests. ## Common causes of bloating Swallowed air from eating quickly, chewing gum or fizzy drinks distends the stomach. **Constipation** traps gas and causes bloating relieved by passing stool. **Irritable bowel syndrome (IBS)** causes bloating with altered bowel habit. Food intolerances such as lactose or coeliac disease may also play a role. ## Managing bloating at home Eat smaller, regular meals and chew thoroughly. Increase fibre gradually and drink enough fluids to support bowel regularity. Gentle exercise aids gut motility. Peppermint tea or oil may ease IBS-related bloating for some people. ## When to see a GP about bloating Persistent bloating for three weeks or more, especially with weight loss, appetite loss, or change in bowel habit, should be assessed. Women with ongoing bloating and pelvic discomfort should mention this to a GP — early investigation of ovarian conditions improves outcomes. ## ! When to get medical help for bloating See a GP if bloating persists for three weeks or more, is getting worse, or occurs with unexplained weight loss, blood in poo, or difficulty eating. Call **111** for urgent advice when you are unsure what to do. ## Common questions about bloating Why do I bloat after eating? Large meals, fatty foods, beans, onions and wheat can produce gas during digestion. Eating quickly and swallowing air also distend the stomach — slowing down and avoiding straws may help. Is bloating always IBS? No — while IBS is a common cause, bloating is also linked to constipation, coeliac disease, lactose intolerance and, less often, ovarian cancer. Persistent symptoms warrant investigation. Can stress cause bloating? Yes — the gut and brain are closely linked. Stress and anxiety can alter gut motility and sensitivity, worsening bloating in IBS. What dietary changes help bloating? Regular meals, adequate fibre, limiting fizzy drinks and identifying trigger foods (sometimes via a food diary) help many people. A dietitian can guide low-FODMAP approaches for IBS. ## Sources - [NHS — Bloating](https://www.nhs.uk/conditions/bloating) - [NHS — Irritable Bowel Syndrome](https://www.nhs.uk/conditions/irritable-bowel-syndrome)
