What are the symptoms of hyperglycemia? I've drunk a lot of water recently ~

Generally speaking, there are no special symptoms. If you drink too much and pee, go to the hospital as soon as possible. My blood sugar was high at that time. I bought a Sanofizim+blood glucose meter in our drugstore. I measure my blood sugar every day with high accuracy. I adjusted my diet according to my blood sugar level, and now my blood sugar level is very good.
