What’s wrong with waking up every day with a very smelly and bitter mouth?

Getting up every day with a very smelly and bitter mouth may be related to chronic gastritis, cholecystitis and periodontal disease.
1. Chronic gastritis: it is one of the more common digestive diseases, including chronic erosive gastritis, atrophic gastritis, etc. It is usually accompanied by different degrees of dyspepsia, and because of the overnight accommodation, patients may have different degrees of bitter mouth or bad breath after waking up in the morning. Generally, the diagnosis can be clarified through fasting gastroscopy.
2. Cholecystitis: When the gallbladder wall is irritated by bad eating habits or gallbladder stones, causing an inflammatory reaction, the patient will also have a bitter and dry mouth after waking up in the morning. As cholecystitis can also cause indigestion, very few people will have bad breath. Generally, ultrasound examination can make a clear diagnosis.
3. Periodontal disease: Root canal inflammation, pulpitis and periodontal abscess can cause bad breath due to the growth of bacteria. An examination by a dentist may reveal abnormalities.
Since there are many factors affecting this, an interview with the doctor is required.
