Where is the problem with bad breath?

Halitosis and bitter mouth may be problems in the mouth, stomach and gallbladder. The specific analysis is as follows:

1.

Oral diseases such as periodontitis, gingivitis and oral ulcers are easy to cause oral flora disorder, resulting in halitosis and bitter mouth.

2.

Stomach diseases such as acute gastritis, chronic gastritis and duodenal ulcer are easy to cause increased gastric acid secretion, which will stimulate stomach tissue contraction and cause gastric acid to be discharged through the mouth, causing halitosis and bitter mouth.

3.

Gallbladder diseases such as gallbladder stones, acute cholecystitis and chronic cholecystitis will affect bile secretion, causing food to be unable to digest in time. If it stays in the stomach for a long time, it will decompose and ferment to produce gas, causing halitosis and affecting the oral microecological environment.
