Why it happens

Slower stomach emptying keeps food in place longer, and slower gut movement lets gas build up. Together they create that tight, puffy feeling.

Constipation, carbonated drinks, sugar alcohols and a sudden jump in fiber or protein shakes can all add to bloating.

When it starts and fades

Bloating is most common early in treatment and after dose steps, similar to other stomach side effects that were mostly mild to moderate in trials.

It often improves as you adjust portions and keep bowel movements regular.

What helps

  • Keep meals small and eat slowly.
  • Limit carbonated drinks and gum, which add swallowed air.
  • Watch for sugar alcohols in low-sugar bars and shakes.
  • Increase fiber gradually and drink more water with it.
  • Walk for 10 to 15 minutes after meals.
  • Treat constipation early, since it often drives bloating.

Common questions

How common is bloating on Wegovy?

In the trials behind the label, 7% of people on Wegovy reported it, vs 5% on placebo.

Why am I so bloated on Zepbound?

Tirzepatide slows digestion, and gas and constipation can build up. Smaller meals and steady fluids help many people.

Does GLP-1 bloating go away?

It often eases after the step-up phase as you adjust how and what you eat.

Can bloating hide weight loss on the scale?

Yes, short term. Gut contents and water can shift the scale by a few pounds, so watch your trend over weeks.
