Sleep and wake up, why?

1. Physiological factors

If the patient has recent psychological stress or overeating before bed, eating too much high-fat food, etc., it will produce more bile during sleep. When he wakes up from sleep, the symptoms of bitter mouth may occur

due to bile reflux gastritis, reflux esophagitis and other reflux diseases, which will lead to poor upper digestive tract motility and slow gastrointestinal emptying, causing bile reflux and bitter mouth when he wakes up from sleep.

3. Hepatobiliary diseases

When he has cholecystitis, gallstones, hepatitis and other diseases, it will lead to abnormal bile metabolism and excretion, resulting in bitter mouth when he wakes up from sleep.
