AI Summary GERD is defined by troublesome symptoms or complications from stomach contents flowing back into the esophagus, and heartburn and regurgitation are its hallmark symptoms.

GERD (Gastroesophageal Reflux Disease or Chronic Acid Reflux)What GERD is, how it is diagnosed, and what to do about it

Medically reviewed.

GERD (gastroesophageal reflux disease, also called chronic acid reflux) happens when stomach contents flow back into the esophagus and cause troublesome symptoms or complications. Heartburn and regurgitation are the hallmark symptoms. GERD is a digestive condition, not a liver condition, but some steps that calm reflux, such as weight loss, also support liver health. Ask your doctor about any symptom that does not improve.

About GERD

What GERD Is and How Doctors Grade It

GERD is a condition in which stomach contents flow back (reflux) into the esophagus, the tube that carries food to your stomach. When this reflux causes troublesome symptoms or complications, doctors call it GERD. The hallmark symptoms are heartburn and regurgitation.

Doctors confirm GERD in one of two ways. The first is visible injury to the lining of the esophagus, such as erosive esophagitis, seen during an endoscopy (a camera exam of the upper digestive tract). The second is an abnormal amount of acid in the esophagus, shown on a reflux monitoring study.

GERD is a complex condition that shows up in different ways from person to person, so doctors no longer treat it as a single disease. Some people have visible injury to the esophagus. Others have symptoms with no visible injury.

When injury is present, doctors grade erosive esophagitis with the Los Angeles (LA) classification. The grade helps show how firmly the findings point to GERD.

Know the signs

Symptoms and Warning Signs

Heartburn and regurgitation are the classic signs of GERD. Some symptoms need prompt attention from a doctor.

Hallmark Symptoms

  • Heartburn
  • Regurgitation (stomach contents coming back up)

Symptoms Outside the Esophagus

  • Chronic cough
  • Hoarseness or laryngitis
  • Frequent throat clearing
  • Asthma

Alarm Symptoms

  • Difficulty swallowing (dysphagia)
  • Weight loss
  • Gastrointestinal bleeding

Getting a diagnosis

How Doctors Diagnose GERD

Doctors often start with your symptoms. If the cause is unclear or symptoms persist, they use tests to look for injury or measure acid in the esophagus.

Trial of Acid-Reducing Medicine
Doctors may first try an 8-week course of a proton pump inhibitor (PPI), a medicine that lowers stomach acid. If symptoms do not improve enough, or return right after you stop, further testing is the next step.
Endoscopy
A camera exam of the esophagus. Doctors use it first when you have alarm symptoms such as trouble swallowing, weight loss, or bleeding. They also use it when a PPI trial fails or when you have several risk factors for Barrett's esophagus. For non-urgent cases, it is ideally done after you have stopped PPI therapy for 2 to 4 weeks.
Reflux Monitoring
A wireless capsule or a thin tube through the nose measures how much acid reaches the esophagus and whether your symptoms line up with reflux events. Doctors use it when GERD is suspected but endoscopy shows no injury. It is usually done with PPIs stopped for 7 days.

Why Testing Matters

Symptoms alone do not always show whether reflux is the cause. Tests help your doctor confirm GERD, check for injury, and choose the right treatment.

Why follow-up matters

When Reflux Causes Lasting Changes

Erosive Esophagitis

Repeated reflux can injure the lining of the esophagus. Doctors grade this injury during endoscopy. Severe grades (C and D) call for a follow-up endoscopy after treatment to confirm the lining has healed.

Barrett's Esophagus

Severe inflammation can hide Barrett's esophagus, a change in the esophagus lining, so doctors look for it after treatment. If abnormal cells or early cancer appear, procedures done through an endoscope can remove them and prevent progression to esophageal cancer. Reflux control remains important during this care, and people with Barrett's esophagus need ongoing surveillance.

Risk factors

What Makes Reflux Worse

Some habits and body factors make reflux more likely or worse, especially at night. Many of them are within your control.

Body and Lifestyle Factors

  • Overweight or obesity
  • Tobacco use and smoking
  • A large hiatal hernia (part of the stomach pushing up through the diaphragm)

Nighttime Habits

  • Eating meals within 2 to 3 hours of bedtime
  • Sleeping on your right side, which increases reflux at night compared with sleeping on your left
  • Nighttime symptoms without the head of the bed raised

Small Changes Add Up

Changing weight, smoking, and bedtime habits together gives you the best chance of easing reflux. Obesity and smoking are also risk factors for esophageal cancer in people with Barrett's esophagus.

Taking action

Managing GERD

Start with Lifestyle Changes

Losing weight is the top lifestyle step if you are overweight or obese. Avoid meals within 2 to 3 hours of bedtime, raise the head of your bed if you have nighttime symptoms, and sleep on your left side instead of your right. If you smoke, quitting helps.

Take Acid-Reducing Medicine Correctly

PPIs are the main medicines for GERD. Take them 30 to 60 minutes before meals, as prescribed. Checking that you take your PPI the right way and on schedule improves symptoms in about 11% to 35% of people who did not respond at first. Never change your dose on your own.

Find the Lowest Effective Plan

People with severe esophagitis (grade C or D) or Barrett's esophagus are advised to stay on PPI therapy long term. For milder disease with symptoms under control, the goal is the lowest effective dose or taking the medicine only when symptoms occur. Your doctor decides which approach fits you.

Ask About Next Steps If Symptoms Persist

Reflux is called refractory when heartburn or regurgitation persists despite 8 to 12 weeks of double-dose PPI therapy. Antireflux surgery, such as Nissen fundoplication, is an option for people with objective evidence of GERD, especially severe esophagitis, large hiatal hernias, or those who want to avoid lifelong medicine.

Diet and Bedtime Habits

Eating and Sleeping Habits That Ease Reflux

What and when you eat can affect reflux, and it also affects your liver. Trigger foods differ from person to person, so talk with your doctor or a dietitian about which foods bother you.

A balanced eating pattern, regular physical activity, and gradual weight loss if you are overweight help both reflux and liver health. Avoiding food in the 2 to 3 hours before bedtime is one of the best-supported changes for reflux.

Habits to Build Your Day Around

  • Build your plate around vegetables, fruits, and whole grains.
  • Choose lean protein and healthy fats.
  • Eat smaller portions if you are overweight, to support gradual weight loss of 5% to 10%, and cut back on high-sugar, high-fat, and processed foods.
  • Finish your last meal at least 2 to 3 hours before bed.
  • If you have nighttime symptoms, raise the head of your bed and sleep on your left side.

Common Questions

Frequently Asked Questions

What is GERD?

GERD is a condition in which stomach contents flow back into the esophagus and cause troublesome symptoms or complications. Doctors confirm it by finding injury to the esophagus lining during endoscopy, or by measuring abnormal acid exposure on a reflux monitoring study. Heartburn and regurgitation are the hallmark symptoms. GERD is complex and shows up differently in different people, so your care plan may differ from someone else's.

What are the symptoms of GERD?

Heartburn and regurgitation are the main symptoms. Some people also have a chronic cough, hoarseness, throat clearing, or asthma, but those symptoms are not specific to GERD. Doctors recommend checking for other causes with an ear, nose, and throat or lung specialist before blaming reflux alone. See a doctor promptly if you have trouble swallowing, unplanned weight loss, or bleeding.

Does GERD cause liver disease?

GERD is a digestive condition, and there is no clear evidence here that it causes liver disease. It often appears alongside conditions that also affect the liver, such as obesity, and weight loss helps both reflux and fatty liver disease. Tell your liver specialist about reflux symptoms, and ask before starting any new medicine.

What lifestyle changes help with GERD?

The best-supported changes are losing weight if you are overweight or obese, avoiding meals within 2 to 3 hours of bedtime, and quitting tobacco. If you have nighttime symptoms, raising the head of your bed can help. Sleeping on your left side rather than your right side also reduces reflux at night. These steps work best alongside any medicine your doctor prescribes.

How is GERD treated with medicine?

The main medicines are proton pump inhibitors (PPIs), which lower stomach acid. Take them 30 to 60 minutes before meals, as prescribed. People with severe esophagitis (grade C or D) or Barrett's esophagus are advised to stay on a PPI long term. People with milder disease may use the lowest effective dose or take it only when symptoms occur. Ask your doctor before changing your dose.

When do I need an endoscopy or other tests?

Your doctor may recommend endoscopy if symptoms do not improve after an 8-week PPI trial, return right after you stop, or come with alarm symptoms such as trouble swallowing, weight loss, or bleeding. It is also used when you have several risk factors for Barrett's esophagus. When GERD is suspected but endoscopy shows no injury, reflux monitoring can confirm the diagnosis.

When is surgery considered for GERD?

Antireflux surgery, such as Nissen fundoplication, is a long-term option for people with objective evidence of GERD. Those most likely to benefit have severe esophagitis (grade C or D), a large hiatal hernia, or symptoms that respond well to PPIs but want to avoid lifelong medicine. Talk with your doctor about the risks and benefits.
