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 and may spread to your neck or throat.
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 is more likely if you have a hiatal hernia. A hiatal hernia is a conditions 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 medications can bring on heartburn or make it worse.
Medicines that can cause heartburn include:
Anticholinergics (e.g., for sea sickness)
Beta-blockers for high blood pressure or heart disease
Calcium channel blockers for high blood pressure
Dopamine-like drugs for Parkinson's disease
Progestin for abnormal menstrual bleeding or birth control
Sedatives for anxiety or sleep problems (insomnia)
Theophylline (for asthma or other lung diseases)
Talk to your doctor if you think one of your medicines may be causing heartburn. Never change or stop taking medicine without talking to your doctor 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 doctor if you're still bothered by heartburn after trying these steps.
First, avoid foods and drinks that can trigger reflux, such as:
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 - 4 hours of bedtime. Lying down with a full stomach cause the stomach contents to press harder against the lower esophageal sphincter (LES).
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 - 15 pounds.
Sleep with your head raised about 6 inches. 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 medications:
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.
Call your health care provider if
Get urgent medical care if:
You vomit material that is bloody or looks like coffee grounds.
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 doctor if:
You have heartburn often or it doesn't go away after a few weeks of self-care.
You lose weight that you didn't 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 without talking to your doctor first.
What to expect at your health care provider's office
Heartburn is usually easy to diagnose from the symptoms you describe to your doctor. 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 doctor will do a physical examination 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?
If your symptoms do not get better with home care, your doctor may prescribe medicine to reduce acid. These are stronger than over-the-counter medicines. Any sign of bleeding will need more testing and treatment.
