There are no so-called “three signs of high blood sugar sleep”, but high blood sugar sleep may appear hunger, increased urination at night and other manifestations. 1. Obvious hunger before going to bed. Generally speaking, you will not be hungry before going to bed after eating at night, if you are more obviously hungry before going to bed every day, or need to eat some food to fall asleep, this situation may be caused by high blood sugar. 2. Increased frequency of nocturia. Under normal circumstances at night to sleep generally urinate 0-1 times, for patients with high blood sugar, the number of urination at night to sleep may be significantly increased. If diabetes is suspected, it is recommended to go to a regular hospital and under the guidance of a doctor for standardized diagnosis and treatment, so as to avoid delaying the condition.
