Gastric disharmony refers to gastric disease and gastrointestinal discomfort; restlessness is a sleep disorder, manifested by difficulty in falling asleep, sleep not deep, easy to wake up, not easy to fall asleep after waking, sleepy at night, early waking, feeling tired or lack of wakefulness after waking, etc. In general, patients with chronic gastritis, enteritis, gastric ulcer, duodenal ulcer acute phase insomnia, most of the night is not easy to fall asleep, easy to wake up after sleep, short sleep time, wake up weakness, dizziness, poor memory. It can be seen that “stomach disharmony” does have a close relationship with sleep disorders. Because the spleen and stomach are in the middle jiao, the pivot of the qi flow. If you do not eat properly, damage the intestines and stomach, then gather moisture into drinks, brew heat and phlegm, or stagnant food, congestion in the middle, turbid gas does not descend, disturbing the chest and diaphragm, the heart and mind restlessness and insomnia. Usually do not pay attention to diet, overeating, beyond the scope of stomach acceptance, especially some fried food, fatty meat, sticky rice, sticky noodles, in the stomach for too long, increasing the burden on the stomach, gastrointestinal power weakened, so that the stomach contents can not be emptied in time, there will be bloating, abdominal pain and other symptoms, thus affecting sleep.

When you sleep at night, the blood flow slows down and a large amount of blood gathers in the stomach to participate in digestion due to a full stomach, then the blood supply to the heart and brain decreases, and the chance of myocardial infarction or cerebral infarction increases dramatically.
