Yes - the ketones are due to the body's starvation response, so when you have d&v, the body tries to break down fats for fuel, making ketones, but in the absence of sufficient insulin the ketones just build up to toxic levels. So despite not feeling like eating/drinking, if you have low/hypo BGs and high ketones, you must take in some fast acting carbs with a little insulin (we use things like ribena, sugary jelly, ice lollies, etc for this purpose). If your BG is high you can just take more insulin to clear ketones and bring down BG. If you can't manage, you MUST go to hospital for intravenous glucose and insulin. My son has had several tummy bugs over the years and they're hard work with type 1, but we've avoided hospital luckily - did have a bag packed ready once! I recommend getting your hubby to do the nursing when your little ones are sick, to reduce your risk of catching it 😉
