H. pylori may cause bad breath, but not all bad breath is due to H. pylori infection.
H. pylori is a bacterium that parasitizes the human stomach. The bacterium contains a large amount of urease, which breaks down urea to produce ammonia gas, and when the gas reaches the mouth through the esophagus, it may cause bad breath.
Helicobacter pylori infection can cause some damage to the gastric mucosa, which is closely related to the development of chronic gastritis, peptic ulcer, gastric cancer and other diseases, affecting the patient’s digestion and absorption function, causing indigestion, making the food stay in the gastrointestinal tract for a longer period of time, and the decomposition of the gas produced by the ammonia-containing or nitrogen-containing gases increase, causing bad breath.
Patients with H. pylori infection may also suffer from acid reflux, heartburn, and belching (burping).
Therefore, H. pylori infection may cause bad breath, but it is not necessarily caused by H. pylori infection. Certain oral diseases, such as dental caries, gingivitis, or poor oral hygiene, can cause bad breath.
Patients with bad breath are advised to consult a doctor in time to identify the cause of the disease and carry out targeted treatment to avoid delaying the condition.
