Reflux / GERD
Learn about GERD- Risk factors, Symptoms, Test & Diagnosis
Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus.
Risk factors
Conditions that can increase your risk of GERD include:
- Obesity
- Bulging of the top of the stomach up into the diaphragm (hiatal hernia)
- Pregnancy
- Connective tissue disorders, such as scleroderma
- Delayed stomach emptying
Factors that can aggravate acid reflux include:
- Smoking
- Eating large meals or eating late at night
- Eating certain foods (triggers) such as fatty or fried foods
- Drinking certain beverages, such as alcohol or coffee
- Taking certain medications, such as aspirin
Symptoms
Common signs and symptoms of GERD include:
- A burning sensation in your chest (heartburn), usually after eating, which might be worse at night
- Chest pain
- Difficulty swallowing
- Regurgitation of food or sour liquid
- Sensation of a lump in your throat
If you have nighttime acid reflux, you might also experience:
- Chronic cough
- Laryngitis
- New or worsening asthma
- Disrupted sleep
When to see a doctor
Seek immediate medical care if you have chest pain, especially if you also have 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
- Take over-the-counter medications for heartburn more than twice a week
Test and Diagnosis
Your doctor might be able to diagnose GERD based on a physical examination and history of your signs and symptoms.
To confirm a diagnosis of GERD, or to check for complications, your doctor might recommend:
- Upper endoscopy. Your doctor inserts a thin, flexible tube equipped with a light and camera (endoscope) down your throat, to examine the inside of your esophagus and stomach. Test results can often be normal when reflux is present, but an endoscopy may detect inflammation of the esophagus (esophagitis) or other complications. An endoscopy can also be used to collect a sample of tissue (biopsy) to be tested for complications such as Barrett's esophagus.
- Ambulatory acid (pH) probe test. A monitor is placed in your esophagus to identify when, and for how long, stomach acid regurgitates there. The monitor connects to a small computer that you wear around your waist or with a strap over your shoulder. The monitor might be a thin, flexible tube (catheter) that's threaded through your nose into your esophagus, or a clip that's placed in your esophagus during an endoscopy and that gets passed into your stool after about two days.
- Esophageal manometry. This test measures the rhythmic muscle contractions in your esophagus when you swallow. Esophageal manometry also measures the coordination and force exerted by the muscles of your esophagus.
- X-ray of your upper digestive system. X-rays are taken after you drink a chalky liquid that coats and fills the inside lining of your digestive tract. The coating allows your doctor to see a silhouette of your esophagus, stomach and upper intestine. You may also be asked to swallow a barium pill that can help diagnose a narrowing of the esophagus that may interfere with swallowing.
