Most people have experienced heartburn at some point. That burning sensation in the chest after a heavy meal or a cup of coffee is uncomfortable but usually temporary. However, when acid reflux happens repeatedly over time, it can develop into a chronic condition called gastroesophageal reflux disease, or GERD.
GERD affects millions of Americans and can range from a persistent nuisance to a condition that significantly disrupts sleep, eating, and quality of life. Left untreated, it can also cause serious complications. The good news is that GERD is highly manageable with the right combination of lifestyle changes, medication, and in some cases, a minor procedure.
What Is GERD?
GERD stands for gastroesophageal reflux disease. It occurs when stomach acid repeatedly flows back up into the esophagus, the tube connecting your mouth to your stomach, causing irritation and inflammation of the esophageal lining.
The key structure involved is the lower esophageal sphincter (LES), a circular band of muscle at the base of the esophagus. Normally the LES opens to allow food into the stomach and then closes tightly. In people with GERD, this sphincter weakens or does not close properly, allowing acid to leak back up.
Occasional acid reflux is common and not a cause for concern. GERD is diagnosed when reflux becomes frequent enough to cause bothersome symptoms or damage.
Common Symptoms of GERD
The most recognizable symptom of GERD is heartburn, but the condition can produce a wider range of symptoms than most people realize.
- Heartburn: a burning sensation in the chest, often starting behind the breastbone and sometimes reaching the throat, typically worse after eating, at night, or when lying down
- Regurgitation: backwash of food or sour liquid into the throat or mouth
- Upper abdominal or chest pain
- Trouble swallowing (dysphagia): a feeling that food is sticking or not going down properly
- Sensation of a lump in the throat
Note: Nighttime acid reflux can cause additional symptoms including a persistent cough, laryngitis, and new or worsening asthma. Many people do not realize their chronic cough or voice changes are connected to GERD.
When to Seek Immediate Care
Chest pain is a symptom of both GERD and heart attack. Do not assume chest pain is just heartburn.
Call 911 or go to the ER immediately if chest pain is accompanied by:
– Shortness of breath – Pain radiating to the jaw or arm – Sweating or nausea without an obvious food-related cause
These are warning signs of a possible heart attack.
For GERD-related concerns without emergency symptoms, see a provider if:
– You are using nonprescription heartburn medication more than twice a week – Symptoms are severe or significantly affecting your sleep or daily life – You have difficulty swallowing or feel like food is getting stuck – You have unexplained weight loss alongside reflux symptoms
What Causes GERD?
GERD develops when the lower esophageal sphincter weakens or relaxes inappropriately. Several factors contribute to this.
- Obesity: excess abdominal weight puts upward pressure on the stomach and sphincter
- Hiatal hernia: when the upper part of the stomach bulges through the diaphragm into the chest cavity
- Pregnancy: hormonal changes and abdominal pressure both contribute
- Connective tissue disorders such as scleroderma
- Delayed stomach emptying (gastroparesis)
Note: Common lifestyle triggers that worsen reflux include smoking, eating large or late meals, consuming fatty or fried foods, drinking alcohol or caffeinated beverages, eating chocolate or peppermint, and wearing tight clothing around the waist.
Complications of Untreated GERD
Chronic acid exposure in the esophagus causes progressive damage over time. Key complications include:
Esophagitis: Inflammation of the esophageal lining from repeated acid contact. Can cause pain, bleeding, and open sores in the esophagus.
Esophageal stricture: Repeated acid damage leads to scar tissue formation, gradually narrowing the esophagus and making swallowing increasingly difficult.
Barrett esophagus: Chronic acid damage can alter the cellular lining of the lower esophagus, creating precancerous changes associated with a significantly increased risk of esophageal cancer.
Note: Barrett esophagus typically produces no additional symptoms beyond those of GERD itself. Regular endoscopic monitoring is the only way to detect it and track for cancerous changes.
How Is GERD Diagnosed?
A provider can often diagnose GERD based on symptoms and medical history. When symptoms are severe, atypical, or do not respond to initial treatment, additional testing may be ordered.
Upper endoscopy: A thin, flexible tube with a camera is passed through the mouth to inspect the esophagus and stomach directly. The most reliable way to evaluate esophageal inflammation, ulcers, strictures, or Barrett esophagus. A biopsy can be taken during the procedure if needed.
Ambulatory acid (pH) probe test: A small monitor placed in the esophagus measures acid levels over 24 to 48 hours to determine how frequently acid is reaching the esophagus.
Esophageal manometry: Measures the strength and coordination of esophageal muscle contractions during swallowing. Particularly useful when difficulty swallowing is prominent.
Upper GI X-ray (barium swallow): After drinking a barium liquid that coats the digestive tract, X-rays are taken to evaluate the structure and function of the esophagus. Helpful for identifying narrowing or structural abnormalities.
Lifestyle Changes That Help
Lifestyle modifications are the foundation of GERD management and can significantly reduce symptoms.
Maintain a healthy weight: Excess abdominal fat pushes acid upward. Even modest weight loss can meaningfully reduce GERD symptoms.
Stop smoking: Smoking directly weakens the lower esophageal sphincter.
Elevate the head of your bed: For nighttime reflux, raise the head of the bed 6 to 9 inches using blocks or a wedge under the mattress. Adding extra pillows under your head alone is not effective.
Sleep on your left side: This position reduces the likelihood of nighttime reflux due to the anatomy of the stomach.
Wait before lying down: Allow at least 3 hours after eating before lying down or going to bed.
Eat slowly and chew thoroughly: Putting your fork down between bites and chewing fully reduces the volume of food entering the stomach at once.
Avoid trigger foods and drinks: Common triggers include alcohol, coffee and caffeine, chocolate, fatty and fried foods, peppermint, citrus, and tomato-based foods.
Avoid tight clothing: Anything fitted tightly around the waist increases abdominal pressure on the sphincter.
Note: Alternative remedies such as ginger, chamomile, and slippery elm are sometimes recommended for GERD. None have been clinically proven to treat GERD or reverse esophageal damage. Discuss any complementary approaches with your provider before trying them.
Medications for GERD
When lifestyle changes alone are not enough, several medication options are available from fastest-acting to most powerful.
Antacids: Products like Tums, Rolaids, and Mylanta neutralize stomach acid immediately and provide quick relief but do not reduce acid production or heal esophageal damage. Best for occasional use.
H-2 Blockers: Medications including famotidine (Pepcid AC) and cimetidine (Tagamet HB) reduce the amount of acid the stomach produces. Slower to act than antacids but provide relief for up to 12 hours. Available over the counter and in stronger prescription doses.
Proton Pump Inhibitors (PPIs): Including omeprazole (Prilosec), lansoprazole (Prevacid), and esomeprazole (Nexium), these are the most effective GERD medications. They significantly reduce acid production and allow the esophagus time to heal. Available over the counter and in stronger prescription formulations. Long-term use may reduce absorption of B-12 or magnesium in some people.
Potassium-Competitive Acid Blockers (P-CABs): A newer class including vonoprazan (Voquezna) that may be considered when other medications have not provided adequate relief.
Note: If you are taking any heartburn medication more than twice a week without discussing it with a provider, underlying esophageal damage may be going unaddressed. Let your provider know so they can evaluate and manage appropriately.
Procedures and Surgery for GERD
For people whose GERD does not respond to medication or who prefer to avoid long-term medication use, procedural and surgical options are available.
Fundoplication: The most established surgical treatment. The top of the stomach is wrapped around the lower esophageal sphincter to reinforce it. Most commonly performed laparoscopically. Nissen fundoplication involves a complete wrap; Toupet uses a partial wrap.
LINX device: A small ring of magnetic beads implanted around the junction of the stomach and esophagus. The magnetic force keeps the sphincter closed against reflux while allowing food to pass normally. Placed laparoscopically with no impact on airport security or MRI scans.
Transoral Incisionless Fundoplication (TIF): A newer endoscopic procedure performed through the mouth with no external incision. Tightens the lower esophageal sphincter using polypropylene fasteners. Shorter recovery time than traditional surgery. Not suitable for patients with a large hiatal hernia, though it may be combined with laparoscopic hernia repair in some cases.
Weight-loss surgery: For patients with both GERD and significant obesity, bariatric surgery may address both conditions by reducing abdominal pressure on the stomach.
Note: Surgery is generally considered when symptoms are severe and not controlled by medication, when the patient wants to avoid lifelong medication, or when complications like Barrett esophagus require more definitive management.
Questions to Ask Your Doctor About GERD
Before your appointment, prepare by:
– Writing down all your symptoms, how often they occur, and what triggers them – Noting whether symptoms wake you at night or affect your ability to swallow – Listing all medications, vitamins, and supplements you currently take
Key questions to bring:
- What is the most likely cause of my symptoms?
- Do I need any tests, and how should I prepare for them?
- Is my condition likely to be temporary or will I need long-term management?
- What treatment do you recommend starting with?
- Are there foods, drinks, or activities I should specifically avoid?
- How will I know if treatment is working?
- When should I come back if symptoms are not improving?
