What should you know about frequent belching and flatulence?

Belching mainly releases air from the upper digestive tract, while flatulence reflects gas moving through the bowel. Eating quickly, fizzy drinks, gum and smoking can increase swallowed air. Beans, some vegetables, lactose or other poorly tolerated foods may increase bowel gas. Reflux, gastritis, Helicobacter pylori infection, hiatus hernia and irritable bowel syndrome can also cause digestive discomfort, but gas symptoms do not prove any one diagnosis.

Eat slowly, chew thoroughly and try smaller portions. Limit fizzy drinks and gum, and note whether dairy, legumes or particular sweeteners trigger symptoms. Change one factor at a time and keep a diary of meals, stool changes, pain and bloating. Gentle movement may help gas pass. A pharmacist or GP can review medicines and discuss treatment; read about [Excessive Burping](/symptoms/excessive-burping/) and [Irritable Bowel Syndrome](/conditions/irritable-bowel-syndrome/).

Book an appointment when symptoms persist, disrupt daily life or come with ongoing diarrhoea or constipation, abdominal swelling, vomiting, difficulty swallowing, blood or black stools, or unexplained weight loss. Seek emergency help for severe sudden abdominal pain, a rigid swollen abdomen, chest pain, breathlessness or fainting. [Gastritis](/conditions/gastritis/) and other conditions may need targeted assessment.

Could food intolerance, reflux, gastritis or bowel sensitivity explain both symptoms? Should I alter my diet or have testing? Which warning signs should prompt urgent care?
