Why does Mounjaro cause sulphur burps?

Mounjaro contains tirzepatide, which intentionally slows down stomach emptying (gastric emptying). Because food stays in the stomach for longer, it has more time to ferment, leading to hydrogen sulphide gas production, bloating, and egg-like smelling burps.

Which foods trigger sulphur burps on Mounjaro?

Certain foods are more likely to produce hydrogen sulphide gas when digestion is delayed. Main triggers include eggs, red meat, onions, garlic, high-fat or greasy meals, and cruciferous vegetables like broccoli and cauliflower.

How can I reduce nausea and stomach issues on Mounjaro?

You can manage gastrointestinal symptoms by eating smaller, slower meals, avoiding greasy and high-fat foods, staying well-hydrated, and remaining upright for at least two hours after eating to reduce reflux and gas buildup.

Should I stop taking Mounjaro if I get sulphur burps?

Not necessarily. Sulphur burps alone are not a medical reason to stop treatment. They are uncomfortable but usually temporary and manageable with dietary and behavioural changes. If symptoms are severe or persistent, speak to your prescriber about adjusting your titration schedule.
