1, oral reasons, such as poor oral hygiene, gingivitis, periodontitis, dental caries, oral mucosal diseases and other diseases;
2. Nasopharyngeal problems such as chronic rhinitis and chronic pharyngitis;
3, respiratory problems, lung problems;
4. Gastrointestinal diseases.
If there is nothing wrong with the mouth, nasal cavity and respiratory tract, it is simply gastrointestinal disease. If you mainly check the problems of stomach diseases, such as chronic gastritis and functional gastroenteropathy, it is easy to have indigestion, acid reflux and belching. This problem needs to be examined. For example, gastroscopy can rule out whether there are organic lesions in the stomach, such as tumors and ulcers. After examination, the diagnosis and treatment of the corresponding diseases were confirmed. In addition, we can do the detection of helicobacter pylori and carbon 14 breath test. If the test result is positive, Helicobacter pylori will be eradicated and stomach trouble may be cured. Because chronic gastritis, ulcers, and even other malignant lymphoma diseases of the stomach are related to Helicobacter pylori.
