What should you know about heartburn and gas chews?

Heartburn is a burning feeling caused when stomach contents move upwards into the food pipe. Gas can add pressure, belching or abdominal fullness, so the two sensations may occur after a large meal or when lying down. A chew may contain an antacid, an alginate, an antiflatulent ingredient, or a combination; check the active ingredients rather than assuming every product works the same way. Heartburn can occur with acid reflux, gastritis, a hiatus hernia or a peptic ulcer, but these symptoms alone do not identify one condition.

Follow the package directions and do not take more than the stated amount. Leave the recommended spacing from other medicines because antacids can affect absorption. Eat smaller meals, remain upright after eating, and notice whether fatty foods, spicy foods, fizzy drinks or late meals trigger symptoms. A pharmacist can check the ingredients against your medicines and health conditions. If you need chews repeatedly, discuss acid reflux medication and the underlying pattern with a clinician.

Get urgent help for chest pressure, pain spreading to the arm or jaw, severe breathlessness, fainting, vomiting blood, or black stools. Arrange prompt medical review for trouble swallowing, repeated vomiting, unexplained weight loss, severe abdominal pain, or symptoms that keep returning despite correct use. Do not assume chest burning is digestive, especially if it begins with exertion or feels different from your usual heartburn.

Ask which ingredient suits your symptoms, how it should be separated from your regular medicines, and whether recurring symptoms should be assessed for reflux or another digestive cause.
