Low blood sugar is an uncommon side effect of Wegovy and Mounjaro, affecting fewer than 1 in 100 people without type 2 diabetes.
It’s more likely to affect people who have type 2 diabetes, particularly those taking other medications such as insulin that lower blood sugar levels.
Common symptoms of low blood sugar include:
- Feelings of hunger, dizziness, confusion, tiredness, or weakness
- Mood changes such as anxiety or irritability
- Sweating
- Shaking
- Tingling lips
- Heart palpitations
- Changes in vision including blurred vision
| When to Contact Your GP or call 111 |
If you experience any of the above symptoms you should call 111 immediately. Have something sugary straight away - like fruit juice, a fizzy drink, glucose tablets or sweets. Once you start feeling better, follow up with something longer-lasting, like a slice of bread or some biscuits, to help keep your blood sugar steady.
If you’re having low blood sugar episodes often, it’s important to speak to your GP. Make sure you tell them you have been taking weight loss medication and please inform your MedExpress clinical prescriber via email.
| When to Seek Urgent Help |
In rare cases, you could lose consciousness if your blood sugar drops too low. This is a medical emergency. If you think someone has very low blood sugar and they are not responding normally, call 999 or go to A&E.
