What is GERD?

GERD (gastroesophageal reflux disease) is a digestive disorder. It's caused when gastric acid from your stomach flows back up into your food pipe (esophagus).

Heartburn is the most common symptom of GERD.

What causes GERD?

GERD happens when gastric acid from your stomach backs up into your food pipe (esophagus).

A muscle at the bottom of the esophagus opens to let food from the bottom of the esophagus into the stomach. And it closes to keep food in the stomach. This muscle is called the lower esophageal sphincter (LES). When your LES relaxes too often or for too long, acid from your stomach backs up into your esophagus. This causes heartburn and may damage the esophagus.

Some lifestyle issues that can cause GERD may include:

• Being overweight

• Lying down or reclining after eating

• Overeating

• Eating foods such as citrus, peppermint, chocolate, and fatty or spicy foods

• Having caffeine

• Having alcohol

• Smoking

• Using aspirin and over-the-counter pain and fever medicines. These include nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen.

Who is at risk for GERD?

You may be more at risk for GERD if you:

• Have a part of your stomach slide up out of the belly cavity next to your esophagus (hiatal hernia)

• Have a weak lower esophageal sphincter or LES

• Are obese

• Are pregnant

• Use some medicines, such as aspirin or over-the-counter pain and fever medicines such as NSAIDs

• Smoke or are around secondhand smoke

• Drink alcohol

• Are older

What are the symptoms of GERD?

Heartburn, also called acid indigestion, or acid reflux, is the most common symptom of GERD. Heartburn is a burning chest pain that starts behind your breastbone and moves up to your neck and throat. It can last as long as 2 hours. It often feels worse after you eat. Lying down or bending over can also cause heartburn. Another common symptom of GERD is bringing swallowed food up again to the mouth (regurgitation). Some people can have trouble swallowing.

Heartburn is not a GERD symptom for most children younger than 12 years old, and for some adults. They may have a dry cough, asthma symptoms, or trouble swallowing instead.

Each person’s symptoms may vary. GERD symptoms can be caused by other health problems. Always see your healthcare provider to be sure.

How is GERD diagnosed?

To see if you have GERD, your healthcare provider will give you a physical exam and ask about your past health. Some people with typical symptoms may be treated without more testing.

Other tests for GERD may include:

• Upper GI (gastrointestinal) series, also called a barium swallow.  This test looks at the organs of the top part of your digestive system. It checks your food pipe (esophagus), stomach, and the first part of your small intestine (duodenum). You will swallow a chalky fluid called barium. Barium coats the organs so that they can be seen on an X-ray.

• Upper endoscopy or EGD (esophagogastroduodenoscopy). This test looks at the lining or inside of your esophagus, stomach, and duodenum. This test uses a thin, lighted tube (endoscope). The tube has a camera at one end. The tube is put into your mouth and throat while you are sedated. Then it goes into your esophagus, stomach, and duodenum. Your healthcare provider can see the inside of these organs. They can also take a small tissue sample (biopsy) if needed.

• Esophageal manometry. This test checks the pressure inside the esophagus, and evaluates for normal muscle contractions (peristalsis) that are required to push food downward through the intestine. A small tube is put into your nostril, then down your throat and into your esophagus.

• pH monitoring. This test checks the pH (acid level) in your esophagus. A thin, plastic tube is placed into your nostril, down your throat, and into your esophagus. The tube has a sensor that measures pH level. The other end of the tube outside your body is attached by a wire to a small monitor that records your pH levels for 24 to 48 hours. During this time, you can go home and do your normal activities. You will need to keep a diary of any symptoms you feel, and also of the food you eat. Your pH readings are checked and compared to your activity for that time period. Another method is to attach a capsule, about the size of a pencil eraser, to the lining inside the esophagus during an EGD. This sends pH data wirelessly to a receiver that can be worn on your wrist, or some other place. The capsule falls off in about 5 days and passes in your stool.

• Impedance testing. This test is able to see reflux of acid, plus nonacid liquid and air. It can be done with pH monitoring.

How is GERD treated?

Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.

In many cases, making diet and lifestyle changes reduces GERD symptoms. Always check with your healthcare provider before making any changes.

If you have GERD, be careful about what you eat and drink. Don’t have too much of these:

• Fried and fatty foods

• Peppermint

• Chocolate

• Alcohol

• Citrus fruit and juices

• Tomato products

• Drinks with caffeine, such as coffee, soda, and energy drinks

You should also:

• Eat smaller amounts

• Not overeat

• Quit smoking

• Not drink too much alcohol

• Wait a few hours after eating before you lie down or go to bed

• Lose weight if needed

• Raise the head of your bed 6 inches. (To do this, put bricks, cinder blocks, or bed risers under the bed legs at the head of the bed.) A "wedge" pillow can also be used while sleeping to raise (elevate) your chest and head above the level of your stomach.

Check any medicines you are taking. Some may cause problems with the lining of your stomach or esophagus. You may also want to talk with your healthcare provider about:

• Taking medicines to reduce your stomach acid (antacids)

• Taking medicines called H2-blockers and proton pump inhibitors to reduce stomach acid.

• Having surgery called fundoplication. This is reserved for severe cases of reflux to prevent the regurgitation of food from the stomach backward into the esophagus.

What are possible complications of GERD?

If GERD is not treated, it can lead to other health problems. These may include:

• Esophagitis. This is an inflammation of the esophagus caused by the acid in your stomach contents. This may lead to ulcers and bleeding in the lining of the esophagus.

• Narrowing of the esophagus, also called strictures. This can make it hard to swallow.

• Chronic cough, laryngitis, or breathing problems.  This happens when stomach contents from your esophagus go into your lungs.

• Barrett’s esophagus.  This complication of GERD occurs when the cells in the lining of your esophagus change, becoming more like the lining of the small intestine. In some cases, it can lead to esophageal cancer.

What can I do to prevent GERD?

Some of the same diet and lifestyle changes that are used to treat GERD can also help to prevent it.

Living with GERD

Your healthcare provider will give you advice on how to manage your GERD symptoms. In most cases, you will need to make some diet and lifestyle changes so that GERD pain won’t get in the way of your normal activities.

When should I call my healthcare provider?

Call your healthcare provider if:

• Your GERD symptoms don’t get better with treatment, or they get worse

• You have new symptoms

• You start vomiting

• You have involuntary weight loss

• You have trouble or pain with swallowing

• You have a new cough or trouble breathing

• You have small amounts of blood in your vomit or stool

• You are losing weight unintentionally
