Gastroesophageal Reflux Disease (GERD)
What is Gastroesophageal Reflux Disease (GERD)?
Gastroesophageal reflux disease, or GERD, happens when stomach acid flows backward into your esophagus. The esophagus is the tube that carries food from your mouth to your stomach. This backward flow irritates the lining of your esophagus and causes uncomfortable symptoms.
Everyone experiences acid reflux occasionally, especially after a big meal. GERD is different because it happens frequently, usually twice a week or more. Over time, repeated acid exposure can damage the esophagus and lead to more serious health problems.
GERD affects about 20 percent of people in the United States. While it can be uncomfortable and disruptive, GERD can often be managed with lifestyle changes, medications, and sometimes medical procedures. Understanding your symptoms and their root causes is the first step toward feeling better.
Symptoms
Common symptoms of GERD include:
- Heartburn, a burning sensation in your chest that often occurs after eating
- Regurgitation of food or sour liquid into your mouth
- Difficulty swallowing or a feeling of food stuck in your throat
- Chest pain, especially when lying down or bending over
- Chronic cough or hoarseness, particularly in the morning
- Disrupted sleep due to nighttime reflux
- Sore throat or a feeling of a lump in your throat
- New or worsening asthma symptoms
- Tooth enamel erosion from stomach acid
Some people with GERD experience mostly digestive symptoms, while others have respiratory or throat symptoms. Symptoms often worsen at night or when lying down.

Causes and risk factors
GERD develops when the lower esophageal sphincter, a ring of muscle at the bottom of your esophagus, becomes weak or relaxes at the wrong times. This sphincter normally acts like a one-way valve, opening to let food into your stomach and closing to keep acid where it belongs. When it malfunctions, stomach acid escapes upward. Factors like obesity, pregnancy, and hiatal hernia can put extra pressure on your stomach and weaken this valve.
Certain lifestyle habits and foods can trigger or worsen GERD symptoms. Smoking weakens the lower esophageal sphincter and increases acid production. Large meals, fatty foods, chocolate, caffeine, alcohol, and acidic foods like tomatoes and citrus can all trigger reflux. Eating close to bedtime or lying down soon after meals also increases your risk. Some medications, including certain blood pressure drugs and pain relievers, can contribute to GERD.
How it's diagnosed
Most doctors diagnose GERD based on your symptoms and medical history. If lifestyle changes and medications do not help, your doctor may recommend additional tests. An upper endoscopy allows a doctor to examine your esophagus with a small camera and check for damage or complications. A pH monitoring test measures acid levels in your esophagus over 24 hours to confirm reflux.
In some cases, blood tests can help identify underlying factors that may contribute to GERD. Gastrin is a hormone that signals your stomach to produce acid. High gastrin levels can lead to excessive acid production, which may worsen reflux symptoms. Histamine is another substance that increases stomach acid. While GERD is not caused by high gastrin or histamine alone, testing these markers can help identify root causes of excessive acid production. Talk to our doctor about whether specialized testing might be helpful for your situation.
Treatment options
Treatment for GERD typically includes a combination of approaches:
- Eating smaller meals throughout the day instead of large meals
- Avoiding trigger foods like chocolate, caffeine, alcohol, fatty foods, and acidic foods
- Maintaining a healthy weight through diet and regular physical activity
- Elevating the head of your bed by 6 to 8 inches
- Avoiding eating within 3 hours of bedtime
- Quitting smoking, which weakens the esophageal sphincter
- Wearing loose-fitting clothing around your abdomen
- Over-the-counter antacids for quick relief of occasional symptoms
- H2 blockers like famotidine to reduce acid production
- Proton pump inhibitors like omeprazole for longer-lasting acid control
- Prescription medications if over-the-counter options are not effective
- Surgical procedures in severe cases that do not respond to other treatments
Work with your doctor to find the right treatment plan for you. Many people find relief through lifestyle changes alone.
Frequently asked questions
Acid reflux is the occasional backward flow of stomach acid into your esophagus. GERD is a chronic condition where acid reflux happens frequently, typically twice a week or more. While everyone experiences acid reflux sometimes, GERD requires ongoing management and can lead to complications if left untreated.
GERD rarely goes away completely without treatment, but symptoms can be well-managed. Lifestyle changes like losing weight, avoiding trigger foods, and eating smaller meals can significantly reduce symptoms. Some people need medications to control acid production. Working with your doctor helps you find the right approach for lasting relief.
Common trigger foods include chocolate, caffeine, alcohol, fatty or fried foods, tomatoes, citrus fruits, garlic, onions, and mint. Spicy foods and carbonated drinks can also worsen symptoms. However, triggers vary from person to person. Keeping a food diary helps you identify which foods affect your symptoms most.
Untreated GERD can lead to serious complications over time. Chronic acid exposure can damage your esophagus, leading to ulcers, strictures, or difficulty swallowing. In some cases, long-term GERD can cause changes in esophageal cells called Barrett's esophagus, which slightly increases cancer risk. Proper treatment helps prevent these complications.
Blood tests cannot directly diagnose GERD, but they can identify factors that contribute to excessive acid production. Tests for gastrin and histamine levels may reveal underlying causes of increased stomach acid. These insights can help your doctor develop a more targeted treatment plan. Your doctor may also recommend other tests like endoscopy or pH monitoring.
Over-the-counter antacids provide relief within minutes but last only a few hours. H2 blockers typically work within an hour and last up to 12 hours. Proton pump inhibitors may take 1 to 4 days to provide full relief but offer longer-lasting control. Lifestyle changes can take several weeks to show significant improvement.
Stress does not directly cause GERD, but it can worsen symptoms. Stress may increase stomach acid production and make you more sensitive to pain. It can also lead to behaviors that trigger reflux, like eating quickly, overeating, or choosing less healthy foods. Managing stress through relaxation techniques, exercise, and adequate sleep may help reduce GERD symptoms.
Many people safely take GERD medications for years when needed. However, long-term use of proton pump inhibitors has been linked to potential risks like nutrient deficiencies and bone fractures. Your doctor can help you find the lowest effective dose and determine if periodic breaks are appropriate. Regular monitoring ensures your treatment remains safe and effective.
Some types of exercise can trigger GERD symptoms, especially high-impact activities or exercises that involve bending over. Running, jumping, and abdominal exercises may worsen reflux. However, regular moderate exercise helps with weight management, which reduces GERD symptoms overall. Try low-impact activities like walking or swimming, and avoid eating within 3 hours before exercising.
See a doctor if you experience heartburn more than twice a week or if over-the-counter medications do not provide relief. Seek immediate medical attention for chest pain, especially if accompanied by shortness of breath or arm pain, as these may indicate a heart problem. Also see your doctor if you have difficulty swallowing, persistent nausea or vomiting, or unintended weight loss.
