Do you fart less on Mounjaro?

Does Mounjaro Reduce Flatulence—Or Make It Worse?

Despite what some might hope, Mounjaro doesn’t help you fart less—in fact, it may do the opposite. While many people taking this medication wonder if it eases digestive symptoms like gas, the reality is a bit more uncomfortable. Mounjaro works by mimicking a hormone that regulates blood sugar and appetite, but one of its side effects is slowing down the digestive process.

When your stomach empties more slowly, food sits longer in your digestive tract. This extended breakdown can lead to increased gas production, leaving many users dealing with more bloating, trapped wind, and yes—more flatulence. It’s not just about occasional discomfort; some people also report experiencing sulphur burps, a distinct and unpleasant side effect caused by the breakdown of certain foods over time.

So, rather than reducing gas, Mounjaro can actually contribute to it. This doesn’t happen to everyone, but it’s common enough to be noted. The good news? For many, these symptoms tend to improve over time as the body adjusts to the medication.

If you're on Mounjaro and noticing more gas than usual, you're not alone. Far from reducing flatulence, Mounjaro may actually increase it due to slowed digestion and greater gas buildup. Simple dietary tweaks—like avoiding gas-producing foods or eating smaller meals—can help ease the discomfort. As always, talking to your healthcare provider about persistent or severe symptoms is wise.
