Gastroesophageal reflux disease (GERD) is a chronic digestive disease. GERD occurs when stomach acid or, occasionally, stomach content, flows back into your food pipe (esophagus). The backwash (reflux) irritates the lining of your esophagus and causes GERD.

Both acid reflux and heartburn are common digestive conditions that many people experience from time to time. When these signs and symptoms occur at least twice each week or interfere with your daily life, or when your doctor can see damage to your esophagus, you may be diagnosed with GERD.

Most people can manage the discomfort of GERD with lifestyle changes and over-the-counter medications. But some people with GERD may need stronger medications, or even surgery, to reduce symptoms.

    GERD signs and symptoms include:

    • A burning sensation in your chest (heartburn), sometimes spreading to your throat, along with a sour taste in your mouth
    • Chest pain
    • Difficulty swallowing (dysphagia)
    • Dry cough
    • Hoarseness or sore throat
    • Regurgitation of food or sour liquid (acid reflux)
    • Sensation of a lump in your throat

    When to see a doctor

    Seek immediate medical attention if you experience chest pain, especially if you have other signs and symptoms, such as shortness of breath or jaw or arm pain. These may be signs and symptoms of a heart attack.

    Make an appointment with your doctor if you experience severe or frequent GERD symptoms. If you take over-the-counter medications for heartburn more than twice a week, see your doctor.

      GERD is caused by frequent acid reflux — the backup of stomach acid or bile into the esophagus.

      When you swallow, the lower esophageal sphincter — a circular band of muscle around the bottom part of your esophagus — relaxes to allow food and liquid to flow down into your stomach. Then it closes again.

      However, if this valve relaxes abnormally or weakens, stomach acid can flow back up into your esophagus, causing frequent heartburn. Sometimes this can disrupt your daily life.

      This constant backwash of acid can irritate the lining of your esophagus, causing it to become inflamed (esophagitis). Over time, the inflammation can wear away the esophageal lining, causing complications such as bleeding, esophageal narrowing or Barrett's esophagus (a precancerous condition).

        Diagnosis of GERD is based on:

        • Your symptoms. Your doctor may be able to diagnose GERD based on frequent heartburn and other symptoms.
        • A test to monitor the amount of acid in your esophagus. Ambulatory acid (pH) probe tests use a device to measure acid for 24 hours. The device identifies when, and for how long, stomach acid regurgitates into your esophagus. One type of monitor is a thin, flexible tube (catheter) that's threaded through your nose into your esophagus. The tube connects to a small computer that you wear around your waist or with a strap over your shoulder.

          Another type is a clip that's placed in your esophagus during endoscopy. The probe transmits a signal, also to a small computer that you wear. After about two days, the probe falls off to be passed in your stool. Your doctor may ask that you stop taking GERD medications to prepare for this test.

          If you have GERD and you're a candidate for surgery, you may also have other tests, such as:

        • An X-ray of your upper digestive system. Sometimes called a barium swallow or upper GI series, this procedure involves drinking a chalky liquid that coats and fills the inside lining of your digestive tract. Then X-rays are taken of your upper digestive tract. The coating allows your doctor to see a silhouette of your esophagus, stomach and upper intestine (duodenum).
        • A flexible tube to look inside your esophagus. Endoscopy is a way to visually examine the inside of your esophagus and stomach. During endoscopy, your doctor inserts a thin, flexible tube equipped with a light and camera (endoscope) down your throat.

          Your doctor may also use endoscopy to collect a sample of tissue (biopsy) for further testing. Endoscopy is useful in looking for complications of reflux, such as Barrett's esophagus.

        • A test to measure the movement of the esophagus. Esophageal motility testing (manometry) measures movement and pressure in the esophagus. The test involves placing a catheter through your nose and into your esophagus.

          Over time, chronic inflammation in your esophagus can lead to complications, including:

          • Narrowing of the esophagus (esophageal stricture). Damage to cells in the lower esophagus from acid exposure leads to formation of scar tissue. The scar tissue narrows the food pathway, causing difficulty swallowing.
          • An open sore in the esophagus (esophageal ulcer). Stomach acid can severely erode tissues in the esophagus, causing an open sore to form. The esophageal ulcer may bleed, cause pain and make swallowing difficult.
          • Precancerous changes to the esophagus (Barrett's esophagus). In Barrett's esophagus, the tissue lining the lower esophagus changes. These changes are associated with an increased risk of esophageal cancer. The risk of cancer is low, but your doctor will likely recommend regular endoscopy exams to look for early warning signs of esophageal cancer.

            No alternative medicine therapies have been proved to treat GERD or to reverse damage to the esophagus. Still, some complementary and alternative therapies may provide some relief, when combined with your doctor's care.

            Talk to your doctor about what alternative GERD treatments may be safe for you. Options may include:

            • Herbal remedies. Herbal remedies sometimes used for GERD symptoms include licorice, slippery elm, chamomile, marshmallow and others. Herbal remedies can have serious side effects, and they may interfere with medications. Ask your doctor about a safe dosage before beginning any herbal remedy.
            • Relaxation therapies. Techniques to calm stress and anxiety may reduce signs and symptoms of GERD. Ask your doctor about relaxation techniques, such as progressive muscle relaxation or guided imagery.
            • Acupuncture. Acupuncture involves inserting thin needles into specific points on your body. Limited evidence suggests it may help people with heartburn, but major studies have not proved a benefit. Ask your doctor whether acupuncture is safe for you.

              Lifestyle changes may help reduce the frequency of heartburn. Consider trying to:

              • Maintain a healthy weight. Excess pounds put pressure on your abdomen, pushing up your stomach and causing acid to back up into your esophagus. If your weight is healthy, work to maintain it. If you are overweight or obese, work to slowly lose weight — no more than 1 or 2 pounds (0.5 to 1 kilogram) a week. Ask your doctor for help in devising a weight-loss strategy that will work for you.
              • Avoid tight-fitting clothing. Clothes that fit tightly around your waist put pressure on your abdomen and the lower esophageal sphincter.
              • Avoid foods and drinks that trigger heartburn. Everyone has specific triggers. Common triggers such as fatty or fried foods, tomato sauce, alcohol, chocolate, mint, garlic, onion, and caffeine may make heartburn worse. Avoid foods you know will trigger your heartburn.
              • Eat smaller meals. Avoid overeating by eating smaller meals.
              • Don't lie down after a meal. Wait at least three hours after eating before lying down or going to bed.
              • Elevate the head of your bed. If you regularly experience heartburn at night or while trying to sleep, put gravity to work for you. Place wood or cement blocks under the feet of your bed so that the head end is raised by 6 to 9 inches. If it's not possible to elevate your bed, you can insert a wedge between your mattress and box spring to elevate your body from the waist up. Wedges are available at drugstores and medical supply stores. Raising your head with additional pillows is not effective.
              • Don't smoke. Smoking decreases the lower esophageal sphincter's ability to function properly.
