Experts remind that bad breath is sometimes the manifestation of some serious medical diseases, so it cannot be ignored. For example, when kidney function is impaired, toxins accumulate in the body, and the patient will exhale a sour apple smell, which is a red flag.
Lung abscess patients are often accompanied by sputum halitosis. Such patients often have fever, purulent sputum, etc., and chest X-rays can generally confirm the diagnosis. In addition, tuberculosis hemoptysis and bronchiectasis hemoptysis often appear bloody bad breath, and patients with advanced lung cancer often have putrid smell in the mouth and exhalation.
Experts recommend that you pay attention to oral hygiene and regularly wash your teeth to prevent bad breath. For halitosis with complex causes, targeted treatment should be carried out after the diagnosis is clear.
