Heartburn is a common ailment that may affect the vast majority of people at some point in their lives. It can be an uncomfortable and concerning symptom. But understanding heartburn and what to do about it can help prevent further complications and keep you on track to better health.

Heartburn is a burning sensation that usually starts in the lower chest and spreads up towards the throat. It’s often accompanied by a sour or acidic taste in the mouth. The pain is caused by acid reflux, which occurs when the stomach's corrosive fluids back up into the esophagus—the tube that connects the throat to the stomach.

There are several factors that can contribute to heartburn, including certain foods, certain medicines, pregnancy, obesity, and certain lifestyle habits such as smoking or drinking alcohol. Eating large meals and lying down soon after eating can also bring on heartburn.

Although heartburn is usually not a sign of a serious health condition, it can be uncomfortable and can interfere with your daily activities. Fortunately, you don’t have to suffer with heartburn. There are some things you can do to help prevent and treat it, such as making simple changes to your diet and lifestyle.

One of the best ways to reduce your risk of heartburn is to adjust your diet. Avoid foods that are known to trigger heartburn, such as spicy foods, citrus fruits, garlic, chocolate, and peppermint. Eating smaller, more frequent meals and drinking more water can also help.

Quitting smoking and reducing the amount of alcohol you drink can also decrease your risk of getting heartburn. Maintaining a healthy weight is also associated with a reduced risk for heartburn. Losing weight if you are overweight or obese can help reduce your risk.

If you do experience heartburn, there are some over-the-counter remedies that may help. An antacid, such as Tums or Rolaids, may help to neutralize stomach acid and provide immediate relief. Acid-blocking drugs, such as Zantac or Prilosec, can also help to reduce stomach acid and relieve symptoms.

Heartburn can be a troubling symptom, but understanding what it is and what you can do to treat it can help you take control. Make simple dietary and lifestyle changes, and talk to your doctor if you’re still having symptoms. With the right treatment, you can get your heartburn under control.
