What is the reason for feeling bitter when sleeping at night

Feeling bitter at night may be related to factors such as poor oral hygiene, strong liver fire, and liver damage.

1. Poor oral hygiene

If the patient does not brush his teeth before going to bed or does not clean them properly when brushing his teeth, the food residue in the mouth will be over-fermented during sleep and produce bitter taste, and the patient may experience bitter taste symptoms.

2. Strong liver fire Traditional

Chinese medicine believes that strong liver fire can reduce the body's ability to dissolve substances, leading to food stagnation and bitter taste, causing bitter taste symptoms.

3. Liver damage

Patients with liver damage are usually accompanied by decreased liver function, which leads to disorders in bile secretion and excretion, causing bile reflux. Bile itself has a bitter taste, so patients may experience bitter taste symptoms.
