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):

1. Align probiotic — took about 5 days to kick in but made a massive difference
2. Digestive enzymes with meals — specifically ones containing alpha-galactosidase
3. 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
4. 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.

OH. I've been eating broccoli every single day because "healthy eating" while on tirz. BROCCOLI. The high-sulfur food. I am a clown. 🤡

NOT THE BROCCOLI 💀💀💀
