A cough that won’t go away after a few weeks tends to get managed with whatever’s in the medicine cabinet — cough syrup, honey and ginger, maybe an antihistamine — long after it should have prompted an actual diagnosis. A chronic cough isn’t a condition on its own; it’s a signal pointing to something underlying, and figuring out what that something is tends to matter more than treating the cough itself. Alliance Hospital BD’s One Stop Respiratory Center in Shyamoli evaluates persistent cough to identify its actual cause, for patients across Shyamoli and nearby Mohammadpur.
This guide covers what counts as a chronic cough, the most common underlying causes, and when it’s time to see a specialist rather than wait it out.
A cough is generally considered chronic when it lasts more than eight weeks in adults (three weeks is often used as an earlier checkpoint worth noting). Anything shorter is usually just the tail end of a cold or acute infection working its way out. A cough that persists well beyond that window, or that keeps recurring in cycles, is what typically prompts further investigation.
A handful of conditions account for the large majority of chronic cough cases, and often more than one is present at once:
Because the symptom — coughing — looks the same regardless of cause, self-diagnosis based on the cough alone is unreliable. What distinguishes these causes is usually the accompanying pattern: timing, triggers, and associated symptoms a doctor asks about during evaluation.
This combination of symptoms warrants prompt evaluation rather than continued home management, as it can point toward conditions like TB or other conditions that benefit significantly from early diagnosis.
Diagnosis typically starts with a detailed history — when the cough started, what makes it better or worse, whether it’s dry or productive, and what other symptoms accompany it. This is often enough to narrow down the likely cause. Depending on the findings, a chest X-ray, pulmonary function testing, or in some cases a trial of treatment for the most likely cause (such as allergy medication or reflux treatment) may be used to confirm the diagnosis.
Cough suppressants can offer short-term relief, but they don’t address whatever is actually driving the cough — which is why symptoms often return once the medication wears off. Effective long-term relief generally comes from identifying and treating the underlying cause, whether that’s managing allergies, treating reflux, starting an inhaler for cough-variant asthma, or adjusting a medication that’s contributing to the problem.
More than one cause is common. It’s not unusual for a chronic cough to have two overlapping contributors — for example, post-nasal drip combined with mild reflux. This is part of why a proper evaluation, rather than trial-and-error with over-the-counter remedies, tends to resolve things faster.
Alliance Hospital’s Chest Medicine department is led by Prof. Dr. Md. Rashidul Hasan, holding an MD in Chest Diseases, with experience working through the range of conditions that can present as a chronic cough.

Patients from Mohammadpur, Adabor, and Kallyanpur can reach the One Stop Respiratory Center within a short drive given its location just off Ring Road in Shyamoli, with the same diagnostic evaluation available near Mohammadpur.
Dealing with a cough that’s lasted weeks without a clear explanation? Alliance Hospital’s Chest Medicine team in Shyamoli can help identify what’s actually causing it.
A cough lasting more than eight weeks in adults is generally classified as chronic and worth a doctor’s evaluation if it hasn’t already been checked, especially if it started without an obvious cause like a cold.
Yes, this is actually fairly common. Reflux can irritate the airway and trigger a cough without producing the classic burning sensation most people associate with heartburn, which is why it’s sometimes overlooked as a cause.
Not necessarily — both can stem from a range of causes, mild to serious. Whether mucus is present is one clue among several a doctor considers, not a reliable indicator of severity on its own.
Yes, a class of blood pressure medications called ACE inhibitors is a well-recognized cause of persistent dry cough in some patients. If this is suspected, the prescribing doctor can discuss alternative options.
Not always immediately, but it’s commonly used, especially if initial findings don’t clearly point to a cause, or if there are any warning symptoms like weight loss or coughing up blood.
