Gastroesophageal Reflux Disease (GERD)
Gastroesophageal reflux disease (GERD) is a condition in which the stomach contents leak backward from the stomach into the esophagus (food pipe). Food travels from your mouth to the stomach through your esophagus. GERD can irritate the food pipe and cause heartburn and other symptoms.
When you eat, food passes from the throat to the stomach through the esophagus. A ring of muscle fibers in the lower esophagus prevents swallowed food from moving back up. These muscle fibers are called the lower esophageal sphincter (LES).
When this ring of muscle does not close all the way, stomach contents can leak back into the esophagus. This is called reflux or gastroesophageal reflux. Reflux may cause symptoms. Harsh stomach acids can also damage the lining of the esophagus. Being pregnant is a major risk factor for GERD due to increased pressure on the abdomen and hormonal changes.
Some pregnant women experience heartburn as often as every day. Other causes and risk factors:
- Consuming alcoholic, caffeinated, or carbonated beverages
- Eating certain foods, such as chocolate, citrus fruits, onions, peppermint, tomatoes, spicy, or fried foods
- Eating large meals
- Eating before bed
- Lying flat soon after eating
- Taking certain medications like aspirin, other medications including certain drugs for asthma, high blood pressure, allergies, depression, sleep disorders, and pain.
Everyone has experienced gastroesophageal reflux. It happens when you burp, have an acid taste in your mouth, or have heartburn. However, if these GERD symptoms interfere with your daily life it is time to see your physician.
Other symptoms that occur less frequently but can indicate that you could have GERD are:
Usually, your provider can tell if you have simple acid reflux (not chronic) by talking with you about your symptoms and medical history. You and your provider can talk about controlling your symptoms through diet and medications. If these strategies don’t help, your provider may ask you to get tested for GERD. Tests for GERD include:
- Upper gastrointestinal GI endoscopy and biopsy: Your provider feeds an endoscope (a long tube with a light attached) through your mouth and throat to look at the lining of your upper GI tract (esophagus and stomach and duodenum). The provider also cuts out a small bit of tissue (biopsy) to examine for GERD or other problems.
- Upper GI series: X-rays of your upper GI tract show any problems related to GERD. You drink barium, a liquid that moves through your tract as the X-ray tech takes pictures.
- Esophageal manometry: A manometry tests the functionality of the lower esophageal sphincter and esophageal muscles to move food normally from the esophagus to the stomach. Your provider inserts a small flexible tube with sensors into your nose. These sensors measure the strength of your sphincter, muscles, and spasms as you swallow.
To prevent and relieve symptoms of GERD, your doctor might encourage you to make changes to your eating habits or other behaviors.
They might also suggest taking over-the-counter medications, like:
- H2 receptor blockers
- Proton pump inhibitors (PPIs)
In some cases, they might prescribe stronger H2 receptor blockers or PPIs. If GERD is severe and not responding to other treatments, surgery might be recommended.
When To See A Doctor
Make an appointment with your doctor if you:
- Experience severe or frequent GERD symptoms
- Take over-the-counter medications for heartburn more than twice a week
