Heartburn occurs when stomach acid percolates up into the esophagus, creating a burning sensation. Taking an over-the-counter antacid medication usually provides the best relief from heartburn.

But a few lifestyle modifications can also reduce the frequency of heartburn.

Control your weight

Being overweight ranks near the top of the risk factors list for heartburn. Excess pounds put pressure on your abdomen, pushing up your stomach and causing acid to back up into your esophagus.

Go with smaller meals

This can help reduce pressure on the lower esophageal sphincter, and prevent the valve from opening and acid from washing back into your esophagus.

Loosen your belt

Tight-fitting clothes can put pressure on the abdomen and the lower esophageal sphincter.

Watch what you eat

Limit fried foods, alcohol, peppermint, chocolate, garlic, onion and caffeine. These are among the most common triggers for heartburn.

Avoid the bends

Avoid stooping or bending for extended periods, especially soon after eating.

Stay upright after eating

Lying down makes it easier for stomach acid to flow back up the esophagus. So don't lie down for a nap following a meal.

When you do lie down, keep your head elevated in bed, about 6 to 9 inches. The best ways to do this is by elevating the head of the bed by placing wooden or cement blocks under the feet at the head end.

Don't smoke

Smoking may increase stomach acid, so lay off the tobacco. Better yet, quit smoking.

Most instances of heartburn prove a temporary annoyance. But if it occurs on a more regular basis, then it could be a sign of gastroesophageal reflux disease (GERD). Persistent heartburn may require a doctor's attention.
