How can I know if I'm still dehydrated and have low blood sugar please help?

If you get dizzy. when you stand up suddenly or if your skin "tents" when you squeeze it, you may be dehydrated. No one, however, who is not on diabetes medication or has end stage cancer, kidney or liver disease, etc. has true hypoglycemia. It's a common medical myth.
Hmmm... Hi. Drink plenty of fluids. Check your blood sugar. What do you consider low??? As an endocrinologist, I'll tell you, unless you're taking insulin, or have a rare-as-hens'-teeth tumor, you're NOT hypoglycemic. That's a self diagnosis, that I'm still waiting to be correct ONCE. Be healthy!
