Daily fibre target for constipation on Mounjaro / Wegovy — plus gentle food ideas and how fast to increase.
Daily fibre target
30g
~12g from gentler soluble sources · raise by ~5g/week · drink ≥2.2 L water

GLP-1-friendly fibre ideas
- Oats or overnight oats (gentle soluble fibre)
- Berries, kiwi or pear with skin
- 1–2 tbsp ground flaxseed or chia in yoghurt
- Cooked lentils, beans or chickpeas (small portions)
- Steamed vegetables + a side salad if tolerated
- Increase fibre by ~5 g/week — jumping too fast can worsen bloating on slowed gastric emptying.
- Pair every fibre bump with extra water; fibre without fluid can worsen constipation.
- Prefer cooked / soft fibres if raw salads feel heavy after dose increases.
- If constipation is severe or lasts days, speak to your pharmacist or prescriber before relying on supplements.

Fibre and constipation on GLP-1 medication
Constipation is one of the most discussed GLP-1 side effects (and shows up in Search Console for queries like “mounjaro constipation” and “constipation relief mounjaro”). Slowed gut transit plus lower food volume means fibre needs a careful, gradual approach with enough water — not a sudden bran overload.
