Many people think that it is easy to get angry, and oral diseases can also cause bad breath, but if it lasts for a long time, it often has bad breath and has not improved, or it may be the software of the cancer sound system. In medicine, patients with esophageal symptoms or stomach tumors will continue to have bad breath, and this persistent bad breath will often get worse after meals.

In addition, if there is weight loss, loss of appetite and a more prominent feeling of flatulence in the mouth, you need to be careful of gastric cancer.

Long-term bad breath should be noted that many patients are in the second half of the stage when they are diagnosed with gastric cancer, and the treatment effect is not good. In fact, careful observation of physiological changes, early detection of abnormal symptoms and early prevention, early diagnosis and early detection can greatly improve the cure rate of gastric cancer. Long-term bad breath is one of the symptoms that need to be careful. Helicobacter pylori can live in dental plaque with many pathogenic bacteria in the mouth, thus forming urease, dissolving urea in the mouth, and finally forming substances with ammonia odor, so many patients infected with HP have oral odor. HP infection is classified as a class I carcinogen by WHO and is one of the main causes of gastric cancer. HP infection will cause inflammatory changes in gastric mucosa, and with the passage of time, inflammation will also make gastric mucosa evolve into gastric cancer. Therefore, if there is persistent and stubborn sour smell or carrion smell in the mouth, we must pay attention to it.

The above symptoms are all distress signals sent by the body, and patients need to go to the hospital for examination in time.
