Illness and insulin
If you are ill with type 1 or 2 diabetes, more glucose is released into your bloodstream and your body becomes resistant to insulin.
If you are ill, more glucose is released into your bloodstream and your body becomes resistant to insulin, which can mean a rise in your blood glucose levels, so you may need to take a higher dose of insulin.
Use the following ‘sick day rules’ to take extra care of your diabetes.
- Call your healthcare team if you need help.
- Keep taking your insulin and/or other diabetes medications even if you don’t feel like eating. You might need more than usual.
- Test your blood glucose levels more often
- Stay well hydrated. Have lots of unsweetened drinks to avoid dehydration
- Eat little and often, and have carbohydrate-containing drinks if you cannot keep food down.
