GERD and bloating: what should you know?

GERD happens when stomach contents move back towards the food pipe, causing burning, sour fluid, throat irritation or upper abdominal discomfort. Bloating is a feeling of fullness or visible abdominal swelling. Swallowed air, constipation, food intolerance and changes in gut movement can cause it, while conditions such as Irritable Bowel Syndrome, Lactose Intolerance, Food Intolerance, Coeliac Disease, Giardiasis or Helicobacter Pylori Infection may need consideration.

Reflux and bloating can reinforce each other: a distended abdomen may increase pressure on the stomach, and discomfort can encourage shallow eating or extra air swallowing. The timing of symptoms matters more than the label. Note whether symptoms follow meals, particular foods, lying down or medicines.

Keep a simple diary of meals, reflux, bowel movements and bloating. Eat slowly, choose smaller meals, avoid lying down soon after eating, and reduce personal triggers rather than removing many foods at once. Gentle movement can support digestion. A clinician or Nutrition Counselling service can help test dietary changes safely, especially if you are losing weight or avoiding major food groups. Do not start a gluten-free diet before discussing Coeliac Disease testing, because this can affect test results.

Arrange a medical review if symptoms persist, repeatedly disturb sleep, or come with difficulty swallowing, repeated vomiting, black stools, persistent abdominal pain, unexplained weight loss, fever or a new change in bowel habit. Seek urgent help for severe sudden pain, vomiting blood, fainting or marked weakness.

Could reflux and bloating have different causes? Which symptoms would make you test for intolerance, infection or Coeliac Disease? Should I review any medicines, and how long should I try a food or meal-timing change?
