Answer snapshot

Topic	Medical Weight Care
Plain-English answer	Gastroesophageal reflux (GER) is when stomach contents come back up into the esophagus, and GERD is the more severe, long-lasting form. NIDDK estimates about 20 percent of U.S. adults have GERD, lists overweight or obesity as a risk factor, and treats symptoms, testing, and treatment as clinical decisions made with a doctor.

Why reflux comes up in medical weight care

Medical weight-care visits often start with medication and cost questions, but reflux symptoms show up in the same conversation for two reasons. NIDDK lists being overweight or having obesity among the factors that can affect the lower esophageal sphincter and lead to GERD, and it lists losing weight, if you are overweight or have obesity, as a lifestyle change doctors may recommend to reduce symptoms.

That does not mean weight change resolves reflux for everyone, or that reflux is caused by weight alone. NIDDK describes GERD as a condition with several contributing factors, including a lower esophageal sphincter that becomes weak or relaxes when it should not, pregnancy, smoking, some medicines, and a hiatal hernia. This page stays in the education lane: what the federal sources say, in plain English, so you can prepare better questions for a clinician.

What GER and GERD mean, in NIDDK’s words

NIDDK explains that gastroesophageal reflux (GER) happens when your stomach contents come back up into your esophagus. Many people have GER once in a while, and GER often happens without causing symptoms. In some cases, GER may cause heartburn, also called acid indigestion. NIDDK notes that doctors also refer to GER as acid indigestion, acid reflux, acid regurgitation, heartburn, or reflux.

NIDDK states that gastroesophageal reflux disease (GERD) is a more severe and long-lasting condition in which GER causes repeated symptoms that are bothersome or leads to complications over time, and it adds that if you think you may have GERD, you should see your doctor. NIDDK estimates that about 20 percent of people in the United States have GERD.

Who is more likely to have GERD

NIDDK states that anyone can develop GERD, and it lists the groups who are more likely to have it: people who are overweight or have obesity, people who are pregnant, people who take certain medicines, and people who smoke or are regularly exposed to secondhand smoke.

NIDDK also names medicines that can cause GERD or make symptoms worse: benzodiazepines, which are sedatives, calcium channel blockers used to treat high blood pressure, certain asthma medicines, nonsteroidal anti-inflammatory drugs (NSAIDs), and tricyclic antidepressants. It adds that a hiatal hernia, a condition in which the opening in your diaphragm lets the upper part of your stomach move up into your chest, can also increase the chance of getting GERD or make symptoms worse.

If you take any of those medicines regularly, that is a conversation to have with the prescriber rather than a reason to stop a medicine on your own.

Symptoms, and the signs NIDDK says mean see a doctor

NIDDK describes heartburn as a painful, burning feeling in the middle of your chest, behind your breastbone, rising from the lower tip of your breastbone toward your throat. It describes regurgitation as stomach contents coming back up through your esophagus and into your throat or mouth, which may cause you to taste food or stomach acid.

NIDDK notes that not all adults with GERD have heartburn or regurgitation. Other symptoms may include chest pain, nausea, problems swallowing or pain while swallowing, and symptoms of complications in the mouth, throat, or lungs, such as chronic cough or hoarseness.

NIDDK says you should see a doctor if you think you have GERD, or if your symptoms do not get better with over-the-counter medicines or lifestyle changes. It also lists symptoms that could be related to GERD complications or other serious health problems: chest pain, loss of appetite, persistent vomiting, problems swallowing or pain while swallowing, signs of bleeding in the digestive tract such as vomit that contains blood or looks like coffee grounds or stool that contains blood or looks black and tarry, and unexplained weight loss. Our guide to warning signs that warrant contacting a clinician covers how urgent symptom questions are handled in the medication path as well.

How doctors diagnose and treat reflux

NIDDK states that in most cases doctors diagnose GER and GERD by reviewing your symptoms and medical history, and that if symptoms suggest GERD, your doctor may recommend treatment with medicines and lifestyle changes instead of doing tests. NIDDK lists three situations where testing may be recommended: symptoms that suggest a complication, symptoms that suggest another health problem with similar symptoms, and symptoms that do not improve after treatment.

Tests NIDDK describes include upper gastrointestinal (GI) endoscopy, in which a doctor uses an endoscope, a flexible tube with a camera, to see the lining of your upper GI tract and may take biopsies for a pathologist to examine, and esophageal pH monitoring, which NIDDK calls the most accurate way to detect stomach acid in the esophagus using either a catheter passed through your nose or a small wireless capsule placed with an endoscope.

For treatment, NIDDK says your doctor may recommend lifestyle changes and medicines, and in some cases surgery. The lifestyle changes it lists include losing weight if you are overweight or have obesity, elevating your head during sleep by placing a foam wedge or extra pillows under your head and upper back to raise your head off your bed 6 to 8 inches, quitting smoking, and changing your eating habits and diet.

Medicines NIDDK describes start with antacids for mild heartburn and other mild symptoms, which it says should not be used every day or for severe symptoms except after discussing antacid use with your doctor. Next come H2 blockers, which lower the amount of acid your stomach makes and can help heal the esophagus. Then come proton pump inhibitors (PPIs), which NIDDK says are better at treating GERD symptoms than H2 blockers and can heal the esophageal lining in most people with GERD. NIDDK notes PPIs are generally safe and effective with uncommon side effects including headache, diarrhea, and upset stomach, and that research suggests taking PPIs may increase the chance of Clostridioides difficile (C. diff) infection.

If symptoms do not improve with lifestyle changes and medicines, NIDDK says your doctor may recommend surgery, and it notes that you are more likely to develop complications from surgery than from medicines. The most common operation is fundoplication, in which a surgeon sews the top of your stomach around the end of your esophagus to add pressure to the lower esophageal sphincter. NIDDK adds that if you have GERD and obesity, your doctor may recommend weight-loss surgery, most often gastric bypass, and that weight-loss surgery can help you lose weight and reduce GERD symptoms. Our guide to metabolic and bariatric surgery in medical weight care covers how those operations are described.

Food, meal timing, and the questions to ask

NIDDK states that if you have GERD and you are overweight or have obesity, your doctor may suggest losing weight to reduce your GERD symptoms, and that your doctor can recommend a healthy eating plan to help you lose weight. It also states that if you have GERD symptoms at night or when you are lying down, eating meals at least 3 hours before you lie down or go to bed may improve symptoms.

On triggers, NIDDK says some people who have GERD find that certain foods or drinks trigger symptoms or make symptoms worse, and it lists those commonly linked to GERD symptoms: acidic foods such as citrus fruits and tomatoes, alcoholic drinks, chocolate, coffee and other sources of caffeine, high-fat foods, mint, and spicy foods. NIDDK advises talking with your doctor about your diet and the foods or drinks that seem to increase your symptoms.

None of this works the same way for every person, and NIDDK frames it as a discussion with your doctor rather than a fixed set of rules. If you are starting or taking a weight-care medicine and reflux symptoms change, that belongs in the same conversation.

Bring a short list to your next visit: when symptoms happen, whether they wake you at night, what you have already tried, which medicines and supplements you take, and any symptoms from the see-a-doctor list above.
