Let’s talk about the one side effect that nobody wants to mention at a dinner party, but almost everyone on a GLP-1 journey experiences at some point: sulfur burps.
If you’ve ever woken up in the middle of the night feeling like there is a “rotting egg” sensation in your throat, you aren’t alone. Whether you are on Zepbound, Mounjaro, or Wegovy, this side effect is more than just embarrassing—it’s a sign that your digestion has hit a standstill.
As someone who has lost 113 pounds on this journey, I’ve learned that we can’t just “tough it out.” To keep losing weight and feeling our best, we have to understand why this is happening and how to fix it so we can keep hitting our protein goals without the discomfort.

💨 Why Does it Smell Like Sulfur?
The “why” is actually quite scientific. GLP-1 medications work by slowing down gastric emptying. This means that the high-protein meals we eat to protect our muscles stay in our stomachs significantly longer than they used to.
When protein sits in the warm environment of your stomach for too long without being broken down properly, it begins to ferment. This process releases hydrogen sulfide gas—hence the “rotting egg” smell. Essentially, your protein is “sitting still” instead of moving through your system and fueling your body.
✨ 3 Quick Tips to Use Today
While your enzymes get to work, here is what I do when I feel a “burp” episode coming on:
- Sip Ginger or Peppermint Tea: If you love Ginger Tea, it’s a natural prokinetic, meaning it helps gently nudge your stomach to empty.
- Smaller, Frequent Protein Hits: Instead of one large meal, try having a small high-protein snack or half a shake, then finishing the rest an hour later.
- The “Blender Hack: If you’re drinking your protein, use a high-speed blender for at least 60 seconds to ensure it’s perfectly smooth. Any undissolved clumps are even harder for your stomach to process when your digestion is slowed!
