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.
