Norovirus Cases on the Rise in the UK: Stay Safe While Using Mounjaro or Wegovy
With norovirus cases climbing across the UK, it’s important to take extra care, especially if you’re using Mounjaro or Wegovy (medications often prescribed for weight management). Norovirus, a highly contagious stomach bug, can cause nasty symptoms like vomiting and diarrhoea, which might feel harder to handle if you’re on these medications. Don’t worry—we’ve got you covered with practical tips to help you prevent, manage, and recover if you’re affected.

Norovirus, Mounjaro or Wegovy? What’s the difference?
If you’re using Mounjaro or Wegovy, your body might react a little differently to norovirus. Here’s why:
- Slower Digestion: These medications slow down digestion, which can make it tougher for your body to clear the virus quickly. This might mean nausea and vomiting stick around longer.
- Higher Dehydration Risk: If you’re eating less while on these medications, norovirus can drain your fluids faster, leaving you feeling weak or dizzy.
- Electrolyte Imbalance: Vomiting and diarrhoea can zap your body’s sodium, potassium, and magnesium levels, which might leave you feeling tired or achy.
- Lower Energy Reserves: Eating less food or protein while on these medications might make it harder for your body to fight off infections like norovirus.
Prevention Tips: How to Reduce Your Risk
The best way to deal with norovirus is to avoid it altogether. Here’s how you can protect yourself:
- Wash Your Hands Often: Use soap and water for at least 20 seconds—especially before eating or touching your face. Hand sanitiser won’t cut it against norovirus!
- Clean Surfaces Regularly: Use bleach-based cleaners to wipe down countertops, doorknobs, and other high-touch areas.
- Be Smart About Food: Avoid risky foods like shellfish, leafy greens, and pre-prepared meals that might carry the virus.
- Support Your Gut Health: Consider adding a probiotic to your routine to help keep your digestion strong and resilient.
If You Catch Norovirus, Mounjaro or Wegovy users: How to Handle It
If you do get hit with norovirus, don’t panic. Here’s how to manage your symptoms and feel better faster:
- Stay Hydrated: Sip on fluids with electrolytes, like rehydration solutions (Dioralyte), coconut water, or broth. Small, frequent sips are easier on your stomach.
- Replenish Lost Salts: Try salty snacks or electrolyte drinks to replace the sodium and potassium you lose from vomiting or diarrhoea.
- Stick to Simple Foods: When you feel ready to eat, try bland, easy-to-digest options like bananas, rice, applesauce, or toast (the BRAT diet).
- Rest and Monitor: Take it easy and keep an eye on your weight. A sudden drop might mean you’re dehydrated, not losing fat.
Should You Adjust Your Medication?
If you’re on Mounjaro or Wegovy and catch norovirus, here’s what to consider:
- Mild Symptoms: You can likely continue your medication, but focus on staying hydrated and resting. Drink plenty of fluids and take it easy.
- Severe Symptoms: If vomiting or diarrhoea is intense, consider skipping your next dose until you’re eating and drinking normally again.
- Not Improving?: If symptoms last more than 48 hours or feel unmanageable, reach out to your GP or pharmacist for advice. They can help you figure out the best next steps.
Final Thoughts
Norovirus is no fun, but with a little preparation and care, you can get through it—even while using Mounjaro or Wegovy. Focus on staying hydrated, eating simple foods, and keeping your environment clean. And remember, if you’re ever unsure or feeling worse, don’t hesitate to reach out to a healthcare professional for support.
Stay safe, take care of yourself, and here’s to feeling better soon!
