Low blood sugar (hypoglycaemia) is not usually caused by GLP-1 treatment on its own. It can happen if you have diabetes and take certain diabetes medicines alongside your GLP-1 treatment (injection or tablet), such as insulin or a sulfonylurea like gliclazide. Due to this risk our service is not suitable for patients with Type-1 diabetes or on a sulphonylurea such as gliclazide or insulin.
What does it feel like?
Symptoms can include:
- Shaking
- Sweating
- Weakness
- Dizziness
- Hunger
- Confusion
- A fast heartbeat
What should I do?
Seek medical attention as soon as possible.
If you have symptoms of low blood sugar, follow the hypoglycaemia advice from your healthcare professional and take a source of fast-acting sugar if you are able to.
Take 15 to 20g of fast-acting sugar straight away, such as glucose tablets, a small glass of fruit juice or a sugary drink. Avoid chocolate at first, as the sugar is absorbed more slowly. Check again after 15 to 20 minutes and repeat if you are still low. Then eat a longer-acting carbohydrate, such as a sandwich, biscuits or fruit.
