I cannot with these sulfur burps anymore y'all. I'm on tirz 7.5mg, week 3, and I am BELCHING rotten eggs every 30 minutes. My husband literally left the bedroom last night. My coworker asked me if something died in my office. I'm not even exaggerating.
I've tried:
- Pepto Bismol — helps for like 20 minutes then they come back
- Eating smaller meals — doesn't matter
- Gas-X — lol no
- Cutting out eggs and dairy — nope still happening
PLEASE someone tell me this goes away because I love what this drug is doing for my appetite and weight but I cannot live like this 😭
Oh god I feel this in my SOUL. I had the exact same thing at 7.5mg. It was genuinely affecting my social life. Like I would avoid going to restaurants.
What finally worked for me (combination approach):
- Align probiotic — took about 5 days to kick in but made a massive difference
- Digestive enzymes with meals — specifically ones containing alpha-galactosidase
- STOP eating within 3 hours of injection — this was the biggest one. I inject at night now and don't eat after 6pm on injection day
- Peppermint tea — sounds like BS but genuinely helped
The burps mostly resolved by week 6-7 for me. Your gut microbiome adjusts. Hang in there 🤢→😊
Gastroenterologist here. The sulfur (hydrogen sulfide) eructation is one of the most common complaints I hear from my tirzepatide patients, probably affecting 15-20% to some clinically meaningful degree.
The mechanism is likely related to delayed gastric emptying — food sits in the stomach longer, sulfur-reducing bacteria (particularly Desulfovibrio species) produce H₂S gas from dietary sulfur-containing amino acids (methionine, cysteine). Tirzepatide slows gastric motility significantly, especially during dose escalation.
Evidence-based interventions that actually have some data behind them:
- Bismuth subsalicylate (Pepto) — binds H₂S directly but short-acting, as you've discovered
- Probiotics — can shift gut flora away from sulfur-reducing bacteria. Lactobacillus and Bifidobacterium strains have the most support
- Reducing high-sulfur foods — cruciferous vegetables (broccoli, cauliflower, cabbage), alliums (garlic, onions), and high-protein meals are the main dietary sources. Dairy and eggs are less impactful than people assume
- Simethicone (Gas-X) — not effective for sulfur burps specifically. It breaks up gas bubbles but doesn't address H₂S production
It does typically improve within 4-8 weeks as the gut adapts. If it persists beyond dose stabilization, consider a short course of rifaximin — talk to your GI or PCP.
