Gas, bloating and burping: the signs, the causes, when to see a doctor, and what helps
For anyone bothered by burping, bloating, a swollen belly or passing gas, and for the people who care for them. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, part of the NIH) says having gas and some gas symptoms is normal, that many people are bothered by them once in a while, and that some people have gas symptoms that bother them often or affect their daily activities. This page passes on, by name, what NIDDK says: the signs, what is normal, and when to see a doctor; where gas comes from and the health conditions that can cause it; the questions, the exam and the tests; swallowing less air, changing your diet, and kinds of medicine; and the foods, habits and diary that can help. It builds the words to say to a doctor, and prints a card to keep.

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor or nurse has reviewed it. The facts were read on October 17, 2026 on NIDDK’s Gas in the Digestive Tract pages (NIH): the overview, Definition & Facts, Symptoms & Causes, Diagnosis, Treatment and Eating, Diet, & Nutrition, and their Spanish versions; all were last reviewed in June 2021 and say the same things. NIDDK names kinds of medicine only, and so do we. Ours: 911 for chest pain or pressure, pain that spreads to the jaw, neck, arm or back, or shortness of breath; emergency care for severe belly pain that does not ease, a hard, swollen belly, or vomiting while you cannot pass gas or stool; care right away for vomiting blood or black or bloody stool; asking before trying a new medicine or supplement; not cutting out whole food groups for long without asking; the card; 988 when it is too much; health centers when money is tight; and the order of the steps. What we left out: medicine names, brands, doses, research studies, and clinical pages for providers. This page saves nothing and loads no trackers.
