How can you reduce upper stomach bloating?

Bloating high in the abdomen may follow a large meal, fizzy drinks, reflux, indigestion, or swallowed air. Food intolerance can cause discomfort after particular foods, while lactose intolerance is linked to dairy for people who cannot digest lactose well. Coeliac disease, Helicobacter pylori infection, giardiasis, and irritable bowel syndrome can also cause digestive symptoms, so location alone cannot identify the cause.

Try smaller meals, eat without rushing, and remain upright after eating. A gentle walk may help movement of gas and digestion. Reduce fizzy drinks and note whether fatty meals, dairy, wheat-containing foods, or other items trigger symptoms. Avoid starting a gluten-free diet before asking about coeliac testing. A nutrition counsellor can help build a balanced plan while patterns are explored.

Arrange a review when upper abdominal bloating is frequent, unexplained, or accompanied by persistent pain, vomiting, diarrhoea, constipation, weight loss, reduced appetite, or difficulty swallowing. Seek urgent help for severe sudden pain, vomiting blood, black stools, fainting, or a rigid or rapidly swollen abdomen.

Could reflux, indigestion, food intolerance, or an infection explain the position of my symptoms? Do I need coeliac, stool, or Helicobacter pylori testing? Which changes should I try first, and for how long?
