What causes sleep pain?

Bitter taste in sleep may be caused by poor oral hygiene, indigestion, bile reflux gastritis and other reasons.

1. Poor oral hygiene

If you don't pay attention to oral hygiene daily, food residues will stay in the mouth for a long time. Under the action of temperature and bacteria, they will rot and produce odor, causing bitter taste in the mouth.

2. Indigestion

eats a lot before going to bed. Food cannot be digested normally at night. It may ferment in the stomach, resulting in bitter taste in the morning, accompanied by belching and nausea.

3. Bile reflux gastritis

If you suffer from bile reflux gastritis yourself, when you sleep, bile reflux occurs and enters the mouth, causing the above symptoms.
