Doctor's answer (1)
Dr. Li Jingli
The causes of dry cough are diverse, and mainly include the following:
1. Respiratory diseases: Such as chronic pharyngitis, bronchitis, interstitial pneumonia, bronchial asthma, and pulmonary tuberculosis. These conditions may cause dryness and itching in the throat, airway hyperresponsiveness, or lung infection, leading to dry cough.
2. Environmental factors: Dry air, inhaled allergens such as pollen, dust, animal dander, or long-term exposure to polluted environments may also trigger dry cough.
3. Medication factors: Certain medications, such as ACE inhibitors used to treat hypertension, may cause chronic dry cough.
4. Diseases of other systems: For example, gastroesophageal reflux, where stomach acid irritates nerves in the throat and mouth area, may also lead to dry cough.
If experiencing symptoms of dry cough, it is recommended to seek medical attention promptly.
