If you’ve recently started Mounjaro (tirzepatide) and are experiencing digestive discomfort, you're not alone. One of the most common early side effects is constipation. For many UK patients, the question becomes: “What are the best constipation relief tips while on Mounjaro?”
At PPRX, we help our patients stay comfortable while benefiting from the full weight-loss effects of Mounjaro.
Why Does Mounjaro Cause Constipation?
Mounjaro slows down digestion to:
- Keep you feeling full for longer
- Reduce appetite
- Improve blood sugar regulation
This delayed gastric emptying can also lead to:
- Slower bowel movements
- Bloating or gas
- Mild to moderate constipation, especially in the first few weeks
Mounjaro Constipation Relief Tips (UK-Safe & Practical)
1. Hydrate Consistently
Drink at least 2 to 3 litres of water daily. Dehydration worsens constipation and is common with reduced food intake.
2. Add Fibre Gradually
Boost your intake of:
- Oats, wholegrains, and bran
- Berries, pears, and prunes
- Chia seeds and flaxseeds
If you’re not used to fibre, increase slowly to avoid gas or cramps.
3. Stay Active
Light exercise like:
- Daily walking
- Gentle yoga or stretching
- Short bike rides
…can stimulate digestion and improve regularity.
4. Consider a Fibre Supplement
If diet alone isn’t enough, consider a UK-approved over-the-counter option:
- Fybogel (ispaghula husk)
- Inulin powder
- Psyllium husk
Always take supplements with plenty of water.
5. Try a Stool Softener if Needed
Pharmacist-approved options like:
- Docusate sodium
- Lactulose syrup
- Senna (short-term use only)
Avoid using strong laxatives long-term without guidance.
6. Inject at the Same Time Each Week
Routine matters — keep your body on a consistent schedule to support digestion and reduce discomfort.
7. Limit Constipating Foods
Cut back on:
- Cheese, red meat, and processed foods
- Caffeine and alcohol (both dehydrating)
When to Speak to a Pharmacist
If constipation lasts more than 5–7 days, or becomes painful or severe, contact your GP or PPRX pharmacist. You may need a temporary pause, dose change, or additional support.
