Aoa. My son agee 12 years is diabetic type 1. His bsr is 51 before lunch. Kindly tell me can hee take insuline after lunch. Thnx?

Yes. You still need to cover the carbs he had for lunch; check his blood sugar as directed by his treating physician. He should have specific instructions on how to manage his diabetes- insulin: carb ratio/ correction, what to do when low , how much carbs to give when active etc. Education is key to success! you need to understand ; be comfortable about diabetes to be able to control it better .
