Quick Answer
Cough is often due to viral infection, allergy, reflux, or airway irritation. Most improve with supportive care, but persistent cough needs evaluation.
Emergency Signs
Immediate care is needed for breathlessness, chest pain, blood in sputum, bluish lips, confusion, or oxygen drop.
Common Causes
Common cold, allergic rhinitis, asthma, sinus drip, reflux, smoking exposure, and chest infections are frequent causes.
Suggested Tests
Depending on duration and exam findings, clinicians may suggest CBC, chest X-ray, spirometry, or infection-specific tests.
What To Do Now
Hydrate, avoid smoke exposure, use steam inhalation where appropriate, and follow prescribed medicines.
When To See A Doctor
Review is important if cough lasts more than 2 to 3 weeks, disturbs sleep daily, or is associated with fever, breathlessness, or weight loss.
