What is the cause of dry mouth after waking up?

After waking up, bitter mouth and dry mouth are considered to be caused by poor oral hygiene, liver and gallbladder damp heat, strong stomach fire, etc., as follows:

1. Poor oral hygiene

If the patient does not pay attention to oral hygiene at ordinary times, food residues may accumulate in the teeth, tongue and other parts for a long time, causing bitter mouth and dry mouth symptoms.

2. Liver and gallbladder damp

heat has the function of producing and excreting bile. If damp heat accumulates in the liver and gallbladder, it may lead to abnormal liver and gallbladder drainage function, causing bitter mouth and dry mouth.

3. Strong stomach fire

If the patient likes to eat fat meat, fried chicken, French fries and other rich and sweet foods at ordinary times, it may cause strong stomach fire, affecting the normal decomposition function of the stomach, thus causing food accumulation in the stomach to produce gas, and reverse to the mouth, causing the above symptoms.
