When the blood sugar value is higher than the normal range, it is called hyperglycemia, and hyperglycemia is also one of the “three highs”, and the other “two highs” are hypertension and hyperlipidemia. The normal value of fasting blood sugar is below 6.1mmol/L, and the normal value of blood sugar two hours after meal is below 7.8mmol/L. If it is higher than this range, it is called hyperglycemia. There are more than three situations that can indicate hyperglycemia at night! One, hunger People with high blood sugar, even if they eat dinner late, will have hunger before going to bed, and they will be in a poor mental state, which is related to the abnormal metabolism of blood sugar. When the blood sugar in the patient’s body is too high, the body cannot absorb enough energy, which will lead to their own depressed mental state, and the blood sugar in the body cannot be used effectively, and people will have a strong feeling of hunger. Second, itching Patients with high blood sugar will have itchy and dry skin before going to bed, whether they take a bath or not! This is caused by the slow metabolism when blood sugar is too high. If the patient has a similar phenomenon, it is necessary to pay attention to blood sugar to avoid complications of diabetes! Third, numbness When blood sugar is abnormally high, it will affect the speed and operation of the entire blood circulation in our body. Once the blood circulation in the body is slowed down, it will make the blood flow at the end of the limbs inaccessible, which leads to numbness and coldness in the hands and feet. Therefore, if the patient sleeps before and after, feel the numbness of the hands and feet, we should pay more attention, it is likely to be the signal of elevated blood sugar! Fourth, polyuria The typical symptom of high blood sugar is polyuria, which is due to the abnormal metabolism of blood sugar, resulting in the malfunction of renal tubular reabsorption, the formation of osmotic diuresis and increased urination. Under normal circumstances, the number of bedtime + night urination per person is generally not more than 3 times, if the patient is higher than this value, we should pay attention to whether their own blood sugar is elevated. Diabetes itself is not fatal, but the resulting complications can be frightening. So don’t think that it doesn’t matter if your blood sugar is high, once it develops to a serious level it’s too late, and the control of indicators for people with three highs is not something that can be achieved overnight by medical science, it should be an attitude and persistence towards life, diet and scientific management of health.
