Being too hungry or too full can affect normal sleep and cause patients to have difficulty falling asleep. Because when a person is hungry, the patient will have symptoms such as panic, palpitations, sweating and hand trembling, which, together with psychological and mental factors, can easily lead to insomnia. At night, if there is a reaction of low blood sugar when hungry, it is necessary to elevate blood sugar by eating to slow down the patient’s hunger. However, patients should not eat too much before going to bed. In this case, it is recommended that patients can eat some food like milk, which can slowly raise blood sugar, delay hunger and improve the feeling of satiety. Especially for those who usually have poor sleep quality, drinking milk is a very good choice. Patients should also avoid excessive hunger, because hunger is prone to hypoglycemia, and hypoglycemia may lead to hypoglycemic encephalopathy and problems with consciousness.
