Why am I so bloated and gassy on a GLP-1?

The short answer: Bloating and gas come from food and gas moving through your gut more slowly — common, usually harmless, and helped by smaller meals. This is a common GLP-1 side effect.

Why it happens

Slowed digestion means food and gas linger longer, which feels like bloating and pressure. It's closely linked with constipation — when things back up, bloating follows.

How long it lasts

It usually eases as your gut adapts, and improves a lot when constipation is kept under control.

What helps

  • Smaller, slower meals; don't rush or gulp air
  • Stay on top of constipation with fiber and fluids
  • Walk after meals to move gas through
  • Go easy on carbonated drinks and known gassy foods

When to call your doctor

  • Severe, rapidly worsening bloating with pain and vomiting
  • A hard, distended belly with no gas or bowel movement passing

Track this against your dose. Logging bloating & gas week by week shows whether it's actually easing — and gives your prescriber real data.
