Do I need to take more insulin when I get sick?

If you’re taking insulin, you may require additional doses when feeling unwell, even if your food intake is reduced, or if you experience vomiting or diarrhea. Regularly monitoring your blood glucose levels can help determine if extra insulin is needed, typically in the form of a short-acting insulin, how much.

Have a sick-day action plan and consult it or reach out to your GP or diabetes healthcare provider for guidance on adjusting your insulin dosage or type during illness.

Maintaining adequate fluid and carbohydrate intake when feeling unwell is crucial to prevent dehydration and low blood sugar levels (hypoglycemia, or hypo).
