Dry mouth after waking up may be related to snoring during sleep, bronchitis, heart disease, and other factors.
First of all, consider the digestive disorders of the gastrointestinal tract due to lack of dietary hygiene, excessive consumption of spicy and stimulating foods for a long time, and irregular diet, resulting in indigestion and dry mouth.
Patients who snore during sleep or have diseases such as bronchitis may breathe with their mouths open during sleep and therefore have a dry mouth after waking up.
Patients who are overworked during the day and often sleep with their mouths wide open also have a dry mouth and tongue after waking up.
