When is it time to go to hospital regarding blood sugar level?

Does she have type 1 or type 2? Is she on medication or insulin? Does she have urine strips on hand to check for ketones? Is this unusual? It sounds like the blood sugar is going down. What accounts for the rise and the drop in your view?

Would ask her doctor, see how that can be avoided in the future, and have a follow-up appointment with possible med or insulin change and referrals to a Certified Diabetes Educator (CDE), Registered Diabetes Nutritionist (RDN) and Exercise Physiologist if necessary.

@chaparrar13 welcome to Mayo Clinic Connect. I’ve been a diabetic for 50ish years. I think the 2 members above have brought up some good questions and suggestions. I’m assuming your mom has been diagnosed with some form of diabetes. Has she had training on how to care for herself? If so, would she be willing to share this information with you so you can support her care. If she hasn’t had any training yet perhaps the 2 of you could start lining up these resources and learn together. Usually a provider will set a blood sugar range for the patient to try to stay within. This also includes what do if the patient is out of range. It is important to learn this. Low blood sugar can happen quickly and be life threatening. High blood sugar usually takes longer to develop but can lead to bad complications over time. That is why your question is so important. There is a condition called diabetic ketoacidosis (DKA) that is the result of high blood sugar. It is a toxic amount of ketones in the blood stream and is very serious. You and your mom need to learn about these things and how to prevent them from happening. I would suggest in the meantime if this happens again to call ER or urgent care and ask whether you should bring your mom in. That is what they are there for. I would be inclined to err on the side of caution.
