Sulfur burps and heartburn on a GLP-1: foods that can help

Burps that taste of rotten eggs and a burning feeling behind your breastbone are two things people often mention on a GLP-1 medicine. This guide covers what the labels say, why a slower stomach plays a part, and the food steps that can make meals feel easier. Questions about your dose, or whether a medicine for reflux is right for you, are for your prescriber.

Are burping and heartburn side effects of Ozempic?

Yes, burping and reflux are both listed in the label, though the word “sulfur” isn’t.

The Ozempic prescribing information lists dyspepsia (indigestion), eructation (the medical word for burping), flatulence and gastroesophageal reflux disease (GERD) among the stomach reactions seen in trials. The Wegovy label lists eructation, dyspepsia and GERD among its common reactions, and its Medication Guide names belching, heartburn and upset stomach among the most common side effects. The Zepbound (tirzepatide) label lists eructation, dyspepsia and GERD too.

None of these labels describes burps as smelling of sulfur. That detail comes from people’s own reports.

Why does a GLP-1 cause burping and reflux?

These medicines slow how fast your stomach empties, so food and gas can stay there longer.

The Ozempic, Wegovy and Zepbound labels all say the medicine delays gastric emptying. A fuller stomach for longer means more chance of pressure, burping and food or acid coming back up. The Zepbound label notes the delay is largest after the first dose and eases over time.

Why some burps smell of sulfur isn’t well studied. We couldn’t find good research on GLP-1 medicines and sulfur burps specifically.

Which eating habits help with heartburn and burping?

Smaller meals, less fat, slower eating and staying upright after meals are the steps with the most backing.

A 2022 expert consensus on GLP-1 stomach side effects suggests:

• Smaller portions, more often. Several small meals instead of two or three big ones.
• Less fat. Reduce the fat in meals, and go easy on fried and heavily processed food.
• Eat slowly. Stop when you feel full, and eat only when you’re actually hungry.
• Stay upright. Avoid lying down after a meal, and don’t eat too close to bedtime.

The NIDDK’s reflux advice lines up. It says eating meals at least 3 hours before you lie down or go to bed may improve symptoms. For night-time reflux, it suggests raising your upper body in bed by about 6 to 8 inches with a foam wedge or extra pillows.

For more on portion size, see when you’re not hungry.

Which foods and drinks can make heartburn worse?

Fatty and fried food, alcohol, fizzy drinks, coffee, chocolate, mint, spicy food, citrus and tomato are the usual ones.

The NIDDK lists acidic foods such as citrus fruits and tomatoes, alcohol, chocolate, coffee and other sources of caffeine, high-fat foods, mint and spicy foods as commonly linked to reflux symptoms. The 2022 consensus adds carbonated drinks. The 2025 joint advisory from ACLM, ASN, OMA and TOS says alcohol may make nausea and reflux worse on a GLP-1.

Not everyone reacts to every item. The NIDDK suggests talking with your doctor about the foods and drinks that seem to set off your own symptoms. Nothing here has to go forever. See foods that can feel harder for gentler swaps.

Do sulfur-rich foods cause sulfur burps?

Maybe for some people, but the evidence is anecdotal, so treat food lists as a starting point to test rather than rules.

Foods people often mention include eggs, broccoli, cabbage and cauliflower, onions and garlic, beans and lentils, red meat, and some protein shakes. Many of these are also good sources of protein and fiber, which matter on a GLP-1, so cutting them all at once can cost more than it saves.

A practical approach:

• Change one thing at a time. Swap or shrink one suspect food for a few days and see if anything changes.
• Make portions smaller first. A smaller serving of eggs or beans may sit fine where a big one didn’t.
• Spread protein out. Several small protein servings across the day can feel easier than one large one. The protein guide has ideas.
• Note the pattern. Write down what you ate when the burps came, and bring it to your next appointment.

What can I eat when my stomach feels unsettled?

Small, plain, lower-fat foods, with a drink sipped slowly alongside.

When nausea makes eating hard, the joint advisory suggests breakfast, then small meals every 3 to 4 hours with enough fluids. It also mentions ginger or peppermint tea. Mint is on the NIDDK’s reflux list, though, so ginger may suit you better if heartburn is the main problem. The queasy days guide has more gentle meal ideas.

When should I call my care team?

Call if symptoms are severe, don’t settle, or come with any warning sign.

The NIDDK says to see a doctor if reflux doesn’t improve with over-the-counter medicines or lifestyle changes. Its warning signs include chest pain, persistent vomiting, problems or pain when swallowing, vomit that contains blood or looks like coffee grounds, and black, tarry stools.

The GLP-1 labels also warn about pancreatitis and gallbladder problems. The Wegovy Medication Guide says to call your provider right away for severe stomach pain that won’t go away, with or without vomiting, sometimes felt in your back.

How does Imi help?

Imi takes care of the food side when your stomach feels touchy.

• Gentler days. Lighter meals are planned after a dose or when you log nausea.
• Quick check-ins. Track side effects in a tap, so patterns are easier to share with your prescriber.
• Easy swaps. Ask Imi to “make dinner gentler” and it swaps the meal.
• Protein and water first. Your targets sit at the top of every day, so smaller meals still add up.

Imi helps with food. Your prescriber handles your medication. For the bigger picture, read eating well on a GLP-1 or visit the GLP-1 hub.
