How to Avoid Sulphur Burps on Mounjaro

Tirzepatide, the active substance in Mounjaro, slows the rate at which food moves through the stomach. When food lingers longer than usual, sulphur-containing compounds in certain foods have more time to ferment, producing hydrogen sulphide gas — the source of that egg-like burp. This is a commonly reported effect rather than a sign that something has gone wrong.

Foods and habits that commonly make it worse

• High-sulphur foods: eggs, red meat, cruciferous vegetables (broccoli, cabbage, cauliflower, Brussels sprouts), garlic, and onions are frequent triggers. Reducing portion sizes of these — rather than cutting them completely — often helps.
• Carbonated drinks: fizzy water, sodas, and sparkling beverages introduce extra gas and can worsen burping. Still water and herbal teas tend to sit more comfortably.
• Eating too quickly or too much: because Mounjaro slows gastric emptying, large meals take even longer to clear. Smaller, slower meals reduce the gas build-up.
• Eating close to bedtime: lying down with a full stomach can make symptoms worse. Many people find a gap of at least two to three hours before sleeping makes a noticeable difference.
• Fatty or heavily processed foods: these slow digestion further and can amplify the effect.

Practical steps worth trying

• Eat smaller portions more slowly, chewing thoroughly.
• Stay well hydrated with still water throughout the day.
• Keep a note of which specific foods seem to trigger episodes — patterns vary between individuals.
• Avoid straws, chewing gum, and rushing meals, all of which increase the amount of air swallowed.

For a broader look at sulphur burps on Mounjaro — including why they happen in more detail — that page covers the topic fully. You may also find it useful to read about general burping on Mounjaro, which often overlaps with the sulphur variety. If you are on semaglutide rather than tirzepatide, the same principles apply — see sulphur burps on Wegovy for that perspective.

One of the most useful things you can do when a side effect like this keeps appearing is to log it consistently, so you can start to see your own patterns rather than guessing. GLP Trackr's side-effect tracker lets you note when sulphur burps occur, how uncomfortable they are, and how long they last — building a personal record that is genuinely useful to bring to your next prescriber appointment.

Because the app also includes food logging — with a photo-scan option that identifies what you have eaten — you can start to connect specific meals or ingredients to flare-ups. Over time, the insights surface correlations in your own data, making it much easier to spot whether, for example, eggs at breakfast or a cruciferous-heavy dinner is the culprit for you specifically.

If symptoms are severe, persistent, or are accompanied by anything that concerns you — such as stomach pain or vomiting — contact your healthcare professional promptly rather than waiting to see if they settle. GLP Trackr is a tracking tool that helps you have more informed conversations with your prescriber; it is not a substitute for their advice. Any questions about your dose or whether to continue your medication belong with your prescriber or doctor.

For a full overview of what to expect and how to manage symptoms, the Mounjaro side effects guide is a good starting point.
