Ozempic Gas Smells Like Farts — Is This Normal

You’re Not Alone — Ozempic Frequently Does Cause Foul-Smelling Burps

When your belching starts smelling like sewage after starting Ozempic, this is among the most widely reported side effects of this class of medication.

What You Need to Know

• It’s extremely common
• It’s caused by hydrogen sulfide gas
• It’s temporary for the vast majority
• You don’t have to just suffer through it
• There’s no health risk from the burps themselves

What Makes It So Awful

Hydrogen sulfide (H2S) is perceivable by humans at just 0.5 parts per billion. A microscopic quantity of H2S makes your burps smell terrible. Humans evolved to detect it because in nature, it signals danger — hence the intense reaction.

How to Stop the Smell

Immediate Relief

Pepto-Bismol should be your first grab for neutralizing the odor because it directly neutralizes hydrogen sulfide — a chemical solution to a chemical problem.

Activated Charcoal (NOW Foods) — traps gas before it reaches your mouth. Between-meal dosing is key. Remember the 2-hour medication gap.

Prevention

Digestive Enzymes (Enzymedica) — take with every meal. Breaks down protein before bacteria can ferment it.

Probiotics (Garden of Life) — daily for microbiome rebalancing. The slow game — but may eliminate burps permanently.

What to Eat (and Avoid)

Minimize these until burps resolve:

• Eggs, notably fried or scrambled
• Steak, burgers, sausage
• Brassicas
• Raw garlic especially

Replace with:

• Easily digestible starches
• Lean white protein
• Simple fruits

Together of reducing triggers and using treatments typically resolves sulfur burps within 2-4 weeks on Ozempic.
