Managing Sulphur Burps on Mounjaro
Some people taking Mounjaro (tirzepatide) may experience belching [1] and/or sulphur burps (burps with a strong, rotten egg smell). While not harmful, they can be unpleasant and embarrassing. This guide explains why sulphur burping on Mounjaro can happen and how to manage it. Always speak to your doctor if belching becomes persistent or severe.
Key Takeaways:
Mounjaro can slow digestion, which may cause smelly burps.
This happens because food stays in the stomach longer, allowing bacteria to create gas.
Eating smaller meals, drinking more water, and avoiding fizzy drinks can help.
Cutting down on foods like eggs, red meat, and onions may also reduce sulphur burps.
If burping is severe or comes with stomach pain or weight loss, see a doctor.
Simple remedies like probiotics, herbal teas, and light exercise may also help improve digestion.
Why Does Mounjaro Cause Sulphur Burps?
Sulphur burps happen when the digestive system produces gas containing hydrogen sulphide. This can be triggered by:
Slower stomach emptying:
Mounjaro helps control blood sugar by slowing digestion. However, this can cause food to stay in the stomach longer, allowing bacteria to ferment it and produce gas.
Changes in gut bacteria:
Mounjaro may alter the balance of bacteria in the gut, increasing the production of sulphur-containing gases.
Diet:
Eating foods rich in sulphur such as eggs, red meat, dairy and cruciferous vegetables (like broccoli, cauliflower and cabbage).
Acid reflux or bloating:
Some people on Mounjaro experience acid reflux or bloating, which may worsen burping.
How to Reduce Sulphur Burps While Using Mounjaro
1. Make Simple Dietary Changes
What you eat plays a major role in digestive health. Try:
Reducing high-sulphur foods like eggs, red meat, garlic, onions and cruciferous vegetables.
Drinking more water improves digestion and prevents food from fermenting in the stomach.
Avoiding carbonated drinks and processed foods that may cause gas build-up.
2. Eat Smaller Meals
Since Mounjaro slows digestion, large meals can sit in the stomach longer, worsening gas production. Try:
Eating smaller, more frequent meals to prevent food from fermenting.
Chewing food thoroughly to aid digestion.
3. Stay Active
Light movement after meals can help digestion and reduce gas build-up. Walking for 10–15 minutes after eating may help your stomach process food more efficiently.
4. Improve Your Gut Health
A healthy gut may reduce sulphur burps. Consider:
Probiotic foods: Eating probiotic-rich foods like yoghurt, kefir and sauerkraut may support gut bacteria.
Increasing fibre intake: Foods like oats, bananas and whole grains help digestion.
Avoiding artificial sweeteners: Some sweeteners, like sorbitol, can disrupt gut bacteria and cause bloating.
5. Try Over-the-Counter Remedies
Some medications can help relieve symptoms:
Antacids: May help reduce stomach acid and reflux.
Simethicone: Helps break up gas bubbles in the stomach.
Activated charcoal: May help absorb excess gas.
Always check with a healthcare professional before taking any new medications.
When to See a Doctor
If sulphur burps persist or are accompanied by:
Severe nausea or vomiting
Diarrhoea or stomach pain
Unexplained weight loss
Speak to a doctor, as these could indicate an underlying condition like acid reflux, an infection, or difficulty tolerating Mounjaro.
Mounjaro Burping FAQs
Can Mounjaro Cause Burping?
If you find yourself burping a lot while taking Mounjaro (tirzepatide), it could be a sign of indigestion, heartburn, or acid reflux. If the burping continues, speak to your pharmacist or doctor about a reflux treatment that can be taken alongside Mounjaro. Keeping a food diary may also help identify foods that worsen your symptoms.
How Can I Reduce Burping on Mounjaro?
You can try these simple strategies to reduce burping while on Mounjaro:
Eat slowly and avoid gulping down food.
Avoid using straws or smoking, as they can make you swallow more air.
Limit alcohol and fizzy drinks, which can cause bloating.
Avoid greasy, high-fat, or high-sugar foods, as they can trigger reflux.
Stay hydrated by drinking plenty of water.
Do light exercise such as walking, jogging, or yoga to aid digestion.
Try herbal teas like peppermint, which can soothe digestion.
Take Mounjaro with food to minimise stomach discomfort.
Consider an over-the-counter indigestion remedy, as excess stomach acid could be causing the burping.
If symptoms persist, consult your doctor or pharmacist for further advice.
Final Thoughts
Sulphur burps can be a side effect of Mounjaro due to slower digestion, diet and changes in gut bacteria. Small lifestyle changes like eating smaller meals, staying active, drinking more water and managing your gut health can help reduce symptoms. If symptoms persist, always consult your doctor.
