Hello,
if I understood well, you're not diabetic but you're concerned about the risk of being diabetic due to your symptoms...
The classical diabetic symptoms are excessive urine production,
weight loss and excessive thirst. You should definitely do a fasting blood
glucose test.
Did you have gestational diabetes? Do you have a family history of diabetes type 2?
The test will be decisive for the diagnosing or excluding diabetes.
Since there is suspicion for diabetes because of your symptoms, I suggest you try to avoid too many carbohydrates (particularly simple sugars), eat more fiber and avoid gaining weight.
If you do have diabetes and high blood glucose, then there is no reason for you to feel shaky because of
hypoglycemia. You may feel shaky and weak because of
dehydration. This means that you should drink enough fluids (so as to relieve your thirst) and avoid the carbs.
I hope I've been helpful for you!
If you have more questions, please ask again and I'll be glad to help you more.
Kind Regards!
