- Nausea
- Constipation
- Diarrhoea
- Reflux/heartburn
- Bloating/wind
- Low appetite / difficulty eating enough
- Fatigue
Practical Self-Management Strategies
The guidance below offers safe, practical starting points for managing common GLP-1 side effects. Everyone’s response is different, so individual support allows us to tailor strategies to your needs. Any medication changes should be discussed with your prescriber.
Nausea
Smaller, simpler meals can feel easier than large portions
Eat slowly and stop at comfortable fullness
Reduce very high-fat meals if they worsen symptoms
Stay hydrated with regular sips through the day
Constipation
Hydration and daily movement often help
Increase fibre gradually if tolerated (not all at once)
Consider foods that support regularity (tolerance varies)
Reflux/heartburn
Earlier, lighter evening meals may help
Avoid lying down straight after eating
Notice personal triggers (often fatty/spicy/caffeine for some)
Low appetite / not eating enough
Prioritise protein-first, small “anchor meals”
Use easy-to-tolerate options during rough days
Seek support early if intake becomes very low
These are the most common issues we’re asked about — see FAQs below for more.
Any questions about medication dosing or changes should be discussed with your prescriber.

FAQs: Managing GLP-1 Side Effects
If side effects are affecting eating, energy or day-to-day routine, these answers cover what’s normal, when to speak to your prescriber, and how our team supports you with safe, practical strategies.
1) How long do GLP-1 side effects last?
Many gastrointestinal side effects are most noticeable when starting treatment or during dose increases, and often settle over the first few weeks. If symptoms persist, worsen, or keep disrupting eating and routine, it’s worth getting structured support. Always check with your prescriber if anything feels concerning.
2) Why do GLP-1 medications cause nausea?
GLP-1 medications can slow stomach emptying and change gut motility, which may increase fullness and trigger nausea – especially if meals are larger, higher in fat, or eaten quickly. Practical adjustments to timing, portion size and food choices can make a big difference.
3) Is constipation normal on Mounjaro or Wegovy?
Yes, constipation is common. Slower gut motility, reduced intake, and dehydration can all contribute. General strategies like consistent fluids, gradual fibre increases and gentle movement help, and we can tailor a plan to your symptoms and tolerance.
4) When should I contact my prescriber about side effects?
Contact your prescriber/GP urgently if you can’t keep fluids down, have severe abdominal pain, persistent vomiting, signs of dehydration, or symptoms that are rapidly worsening. For mild to moderate symptoms, we can support you with safe self-management strategies, and will always refer you back for medical review when needed.
5) Can side effects return when I increase my dose?
Yes. Symptoms often flare during dose escalation or changes in routine (travel, stress, disrupted meals). Having a plan ahead of dose changes – including symptom-friendly food structure and hydration strategies – can reduce disruption.
6) Is it normal to feel fatigued on GLP-1?
Some people experience fatigue, often linked to reduced intake, disrupted sleep, low hydration, or difficulty meeting protein and nutrient needs. We help you stabilise intake and build routines that support energy and recovery, while your prescriber remains the right person for medical causes or persistent fatigue.
7) Should I stop GLP-1 medication if I have side effects?
Don’t stop or change medication without speaking to your prescriber. Many side effects can be managed with practical nutrition and routine changes, and your prescriber can advise if medical review or medication adjustment is needed.
8) How can professional support help with GLP-1 side effects?
Professional support helps you stay consistent and safe: we tailor symptom strategies to your appetite and routine, protect nutrition quality with smaller portions, and support habit structure during dose changes. If symptoms suggest medical review, we’ll guide you back to your prescriber promptly.
9) Do you prescribe GLP-1 medications or advise on dosing?
No. We don’t prescribe GLP-1 medications and we don’t give medication dosing advice. We work alongside your prescriber to support nutrition, behaviour change and (where helpful) therapy-led support.
10) What happens in the free 20-minute discovery call?
It’s a confidential fit check. We’ll understand which side effects you’re dealing with and what’s most disruptive, explain how support works, and outline the safest next step, including whether it’s best to involve your prescriber first.
