Heartburn is a painful burning feeling just below or behind the breastbone. Most of the time, it comes from the esophagus. The pain often rises in your chest from your stomach. It may also spread to your neck or throat.

Almost everyone has heartburn sometimes. If you have heartburn very often, you may have gastroesophageal reflux disease (GERD).

Normally when food or liquid enters your stomach, a band of muscle at the end of your esophagus closes off the esophagus. This band is called the lower esophageal sphincter (LES). If this band does not close tightly enough, food or stomach acid can back up (reflux) into the esophagus. The stomach contents can irritate the esophagus and cause heartburn and other symptoms.

Heartburn may be more likely if you have a hiatal hernia. A hiatal hernia is a condition which occurs when the top part of the stomach pokes into the chest cavity. This weakens the LES so that it is easier for acid to back up from the stomach into the esophagus.
Pregnancy and many medicines can bring on heartburn or make it worse.

Medicines that can cause heartburn include:

• Anticholinergics (used for sea sickness)
• Beta-blockers for high blood pressure or heart disease
• Calcium channel blockers for high blood pressure
• Dopamine-like drugs for Parkinson disease
• Progestin for abnormal menstrual bleeding or birth control
• Sedatives for anxiety or sleep problems (insomnia)
• Theophylline (for asthma or other lung diseases)
• Tricyclic antidepressants

Talk to your health care provider if you think one of your medicines may be causing heartburn. Never change or stop taking medicine without talking to your provider first

You should treat heartburn because reflux can damage the lining of your esophagus. This can cause serious problems over time. Changing your habits can be helpful in preventing heartburn and other symptoms of GERD.

The following tips will help you avoid heartburn and other GERD symptoms. Talk to your provider if you are still bothered by heartburn after trying these steps.

First, avoid foods and drinks that can trigger reflux, such as:

• Alcohol
• Caffeine
• Carbonated drinks
• Chocolate
• Citrus fruits and juices
• Peppermint and spearmint
• Spicy or fatty foods, full-fat dairy products
• Tomatoes and tomato sauces

Next, try changing your eating habits:

• Avoid bending over or exercising just after eating.
• Avoid eating within 3 to 4 hours of bedtime. Lying down with a full stomach causes the stomach contents to press harder against the lower esophageal sphincter (LES). This allows reflux to occur.
• Eat smaller meals.

Make other lifestyle changes as needed:

• Avoid tight-fitting belts or clothes that are snug around the waist. These items can squeeze the stomach, and may force food to reflux.
• Lose weight if you are overweight. Obesity increases pressure in the stomach. This pressure can push the stomach contents into the esophagus. In some cases, GERD symptoms go away after an overweight person loses 10 to 15 pounds (4.5 to 6.75 kilograms).
• Sleep with your head raised about 6 inches (15 centimeters). Sleeping with the head higher than the stomach helps prevent digested food from backing up into the esophagus. Place books, bricks, or blocks under the legs at the head of your bed. You can also use a wedge-shaped pillow under your mattress. Sleeping on extra pillows does NOT work well for relieving heartburn because you can slip off the pillows during the night.
• Stop smoking. Chemicals in cigarette smoke weaken the LES.
• Reduce stress. Try yoga, tai chi, or meditation to help relax.

If you still do not have full relief, try over-the-counter medicines:

• Antacids, like Maalox, Mylanta, or Tums help neutralize stomach acid.
• H2 blockers, like Pepcid AC, Tagamet, and Zantac, reduce stomach acid production.
• Proton pump inhibitors, like Prilosec OTC, stop nearly all stomach acid production.

Get urgent medical care if:

• You vomit material that is bloody or looks like coffee grounds.
• Your stools are black (like tar) or maroon.
• You have a burning feeling and a squeezing, crushing, or pressure in your chest. Sometimes people who think they have heartburn are having a heart attack.

Call your provider if:

• You have heartburn often or it does not go away after a few weeks of self-care.You lose weight that you did not want to lose.
• You have trouble swallowing (food feels stuck as it goes down).
• You have a cough or wheezing that does not go away.
• Your symptoms get worse with antacids, H2 blockers, or other treatments.
• You think one of your medicines may be causing heartburn. DO NOT change or stop taking your medicine on your own.

Heartburn is easy to diagnose from your symptoms in most cases. Sometimes, heartburn can be confused with another stomach problem called dyspepsia. If the diagnosis is unclear, you may be sent to a doctor called a gastroenterologist for more testing.

First, your provider will do a physical exam and ask questions about your heartburn, such as:

• When did it begin?
• How long does each episode last?
• Is this the first time you have had heartburn?
• What do you usually eat at each meal? Before you feel heartburn, have you eaten a spicy or fatty meal?
• Do you drink a lot of coffee, other drinks with caffeine, or alcohol?
• Do you smoke?
• Do you wear clothing that is tight in the chest or belly?
• Do you also have pain in the chest, jaw, arm, or somewhere else?
  What medicines are you taking?
• Have you vomited blood or black material?
• Do you have blood in your stools?
• Do you have black, tarry stools?
• Are there other symptoms with your heartburn?

You may need the following tests:

• Esophageal motility to measure the pressure of your LES
• Esophagogastroduodenoscopy (upper endoscopy) to look at the inside lining of your esophagus and stomach
• Upper GI series (most often done for swallowing problems)

If your symptoms do not get better with home care, you may need to take medicine to reduce acid that is stronger than over-the-counter medicines. Any sign of bleeding will need more testing and treatment.
