Sulfur Burps on Mounjaro: Causes and Remedies
Why tirzepatide causes sulfur burps and what you can do about them. Diet changes and tips to reduce this unpleasant side effect.
By Med Consumer Watch Team
Sulfur burps—burps that taste or smell like rotten eggs—are a distinctive and unpleasant side effect some Mounjaro users experience. Here's why they happen and how to reduce them.
Why Mounjaro Causes Sulfur Burps
The mechanism involves:
• Slowed gastric emptying - food sits longer in stomach
• Bacterial fermentation - gut bacteria break down food
• Sulfur-containing foods - produce hydrogen sulfide gas
• Delayed digestion - more time for gas production
The longer food sits in your stomach, the more fermentation occurs.
Foods That Make It Worse
High-sulfur foods to reduce or avoid:
- Eggs (especially yolks)
- Cruciferous vegetables (broccoli, cauliflower, cabbage)
- Garlic and onions
- Red meat
- Dairy products
- Beer and wine
Keep a food diary to identify your personal trigger foods. Everyone's different.
Remedies and Prevention
Strategies that may help:
• Eat smaller, more frequent meals
• Avoid carbonated beverages
• Eat slowly and chew thoroughly
• Try ginger or peppermint tea
• Avoid eating close to bedtime
• Stay upright after eating
• Consider probiotics
When to Seek Help
Contact your provider if:
• Sulfur burps are constant and severe
• Accompanied by significant nausea or vomiting
• You can't maintain adequate nutrition
• Symptoms worsen despite diet changes
Dose adjustment may help in some cases.
The Bottom Line
Sulfur burps on Mounjaro result from slowed digestion allowing food to ferment. Reducing sulfur-containing foods, eating smaller meals, and eating more slowly often help. While unpleasant, this side effect usually improves with dietary adjustments.
