GLP-1 Constipation: Foods That Help (Ozempic, Wegovy & Mounjaro)

By the Basilino team · Published 19 June 2026 · 5 min read

Constipation is one of the most common side effects of GLP-1 medications like Ozempic, Wegovy, Mounjaro and Zepbound. As these medicines slow digestion and your appetite drops, you are often eating less food, less fibre, and drinking less water — a combination that backs things up. The good news: a few simple food and habit changes make a real difference.

This is general information, not medical advice. If constipation is severe, painful, or lasts more than a few days, contact your prescriber — they may suggest a stool softener or other support.

Why GLP-1 medication causes constipation

Three things stack up:

  • Slower gut transit. The same slowed stomach emptying that curbs appetite also slows the whole digestive tract.
  • Eating less. Smaller portions mean less fibre and less bulk to keep things moving.
  • Drinking less. A reduced appetite often means reduced thirst, and dehydration hardens stools.

The fix targets all three: more fibre, more fluid, and gentle movement.

Foods that help with GLP-1 constipation

Add these in gradually — a sudden fibre jump can cause bloating, especially on a slowed gut.

  • Beans and lentils — among the richest fibre sources. Try our red lentil soup or tuna & white bean salad, which add fibre and protein.
  • Oats and chia seeds — soluble fibre that softens stools. Overnight oats are an easy daily habit.
  • Berries, pears, and apples — fruit fibre plus water content.
  • Vegetables — especially leafy greens, broccoli, and carrots.
  • Prunes or kiwi — both have a gentle, well-evidenced laxative effect.
  • Water — the simplest and most overlooked fix. Sip steadily through the day; fibre without fluid can make constipation worse.

Habits that keep things moving

  • Front-load fibre and fluid earlier in the day when your appetite is highest.
  • Move a little — even a short daily walk helps stimulate the gut.
  • Stay consistent — a regular eating rhythm helps establish a regular bathroom rhythm.
  • Increase fibre slowly to avoid gas and bloating on a slowed digestive system.

A simple daily approach

Aim for a fibre source at most meals: oats or chia at breakfast, beans or lentils at lunch, vegetables at dinner — each paired with a glass of water. That steady drip of fibre and fluid is far gentler and more effective than a sudden overhaul.
