Hi. After you have managed to reduce your blood sugar and ketones following some of the advice above probably going to A&E if needed, I think you may need to check your insulin balance with the nurse. It's possible your background insulin needs tweaking up a bit and the nurse can guide you. If you are not carb-counting i.e. adjusting your meal-time insulin to match the mealtime carbs then do ask the nurse for guidance. Do come back if you need more guidance but hopefully your surgery or clinic nurse can help you. Going into DKA should be a very rare event once the insulin is a balanced although some people are an exception.
