What causes gas?

Gas forms when you swallow too much air or when your body doesn't digest certain foods properly. Everyone gets it and most people pass it 13 to 21 times a day.1 In normal people, about 50% of the gas passed from the rectum comes from swallowed air.2

Gas is a source of abdominal bloating and discomfort, too. Many people who have heartburn experience gas as well.

What are the symptoms of gas?

It's easy to identify if you have gas. Symptoms include:

  • Belching or burping: The release of gas through the mouth.
  • Bloating: An uncomfortable, full sensation, or swelling in the abdomen.
  • Flatulence: The release of gas through the anus.

Gelusil® provides gas pressure relief — and relief from heartburn symptoms, too.

The American College of Gastroenterology suggests that simethicone — the active anti-gas ingredient in Gelusil® — may help to prevent excessive belching.3 Simethicone actively works to break down gas bubbles, alleviating painful pressure. Because Gelusil® also contains an antacid, it relieves multiple symptoms that include heartburn and indigestion.

When to see your doctor.

If you're bothered by excessive flatulence, bloating, or discomfort, see your doctor. A medical professional can help to determine or rule out lactose intolerance, gluten intolerance, irritable bowel syndrome, or another medical condition. Ask if Gelusil® is a good choice for you.
