What causes bad breath and how to resolve it

Bad breath is a common symptom that may be caused by various factors. 1. Oral hygiene issues: Poor oral hygiene habits, such as inadequate tooth brushing, dental calculus, or gingivitis, can lead to bacterial growth in the mouth, resulting in bad breath. Regular tooth brushing, flossing, and using mouthwash can effectively improve oral hygiene and reduce halitosis. 2. Gastrointestinal diseases: Digestive system problems such as gastritis, gastroesophageal reflux disease (GERD), or indigestion may cause bad breath. These conditions affect digestive function and produce unpleasant odors. Attention should be paid to dietary habits, spicy and greasy foods should be avoided, and medical examinations should be conducted when necessary. 3. Systemic diseases: Systemic conditions such as diabetes, liver disease, or kidney disease can sometimes cause abnormal breath odors. These situations require blood glucose monitoring or appropriate medical examinations to identify the cause and provide treatment. If bad breath persists, consultation with a physician is recommended to determine the underlying cause and implement appropriate treatment measures.
