This information is for adults with Type 1 diabetes who take multiple daily injections (e.g. background insulin and fast acting insulin) or a twice daily insulin injection (e.g. Novo mix, Humulin M3 ).
People under age 16 should follow different rules, and pregnant women should also follow other rules.
When you are unwell your body doesn’t behave normally to insulin. It is very important to keep checking your glucose levels when you are unwell and if they are above 14mmol, or you are feeling very unwell, to check your ketones.
Never stop taking your insulin
If you take fast acting insulin (e.g. Novorapid, Humalog) you may need to double your fast acting insulin dose if your ketones are above 1.5mmols.
If you take a mix insulin (e.g. Novomix, Humulin M3) and your blood glucose levels are above 14mmol and have ketones, contact the diabetes specialist nurses on 01324 566929 or NHS 24 on 111.
Top 3 tips for managing illness:
- If ketones are above 1.5mmols take extra fast acting insulin
- Drink plenty of fluids
- Eat or drink some carbohydrates
