Chronic Cough Specialist in Sharjah

What is a chronic cough investigation?

Doctors group adult coughs by how long they have lasted. A cough that settles within three weeks is usually the tail end of a cold or chest infection. One that continues beyond eight weeks is defined as chronic, and at that point it has usually moved on from the original trigger and is being kept going by something else.

A chronic cough investigation is a structured search for that something else. It combines a detailed history, an examination and a small number of targeted tests, chosen in a sensible order so that the most likely explanations are confirmed or set aside first. The aim is a named cause and a treatment aimed at it, in place of a series of cough syrups and courses of antibiotics.

At Dar Al Kamal Hospital, Sharjah, the investigation is led by the hospital's pulmonologist, who coordinates the lung tests, the imaging and any input from other specialties.

Who needs it

An assessment is worthwhile for any adult whose cough has lasted longer than eight weeks, or sooner when it is disturbing sleep, work or family life. It is especially useful for people who:

• Have a dry, tickly cough that returns every time they talk, laugh or step into cold air
• Clear their throat constantly or feel mucus running down the back of the nose — a pattern linked to post-nasal drip, which our ENT allergy testing service can help explore
• Cough after meals, on lying down, or first thing in the morning, which can point to acid reflux even when heartburn is absent
• Take a blood pressure medicine from the ACE inhibitor group, a well-recognised cause of a persistent dry cough
• Smoke cigarettes, shisha, dokha or e-cigarettes, or have smoked in the past
• Work around dust, fumes or chemicals, for example in construction or industry
• Have noticed a change in a long-standing cough

The three most frequent causes — asthma, post-nasal drip and reflux — often cause a cough on their own, with none of their classic symptoms. Cough-variant asthma, for example, can produce a cough with no wheeze at all.

What happens

The first visit centres on the history. Your pulmonologist asks when the cough started, whether it is dry or brings up phlegm, what sets it off, whether it is worse at night, and about your home, work and smoking history. In the UAE, questions about air conditioning, mould at home, sandstorms and dusty workplaces are part of that conversation, because they are common local triggers. A full list of your medicines is reviewed at this stage.

After an examination, the first tests are usually:

• A chest X-ray, arranged through radiology, to look at the lungs and heart outline
• Spirometry, a breathing test in which you blow hard into a mouthpiece, to check for airway narrowing typical of asthma or COPD

Depending on the results, further steps may include full pulmonary function testing, a CT scan of the chest for a more detailed view (see chest imaging), or bronchoscopy, where a thin flexible camera is passed into the airways to look directly and take samples. Blood tests and a sputum sample are sometimes added.

Often the most informative step is a treatment trial: a targeted treatment for the most likely cause, followed by a review of how the cough has responded. A clear improvement confirms the diagnosis.

Preparing for it

Bring a written list of every medicine you take, including blood pressure tablets, inhalers and anything bought over the counter. Bring previous chest X-rays, CT scans and reports, however old, since comparison with earlier images is valuable.

A short cough diary kept for a week or two before the visit helps greatly: note when the cough happens, what triggers it, and anything that eases it. If you use inhalers, bring the actual devices so your technique can be checked. Your team will advise whether any inhaler should be paused before spirometry.

Afterwards

Once a cause is identified, your pulmonologist explains it and agrees a plan with you, which may involve treating asthma, reflux or nasal symptoms, adjusting a medicine together with the doctor who prescribes it, or support to stop smoking. When more than one cause is contributing, each is addressed in turn. A follow-up appointment checks progress.

Keep taking your prescribed medicines unless your doctor advises a change. Do not stop a blood pressure medicine on your own; ask the prescribing doctor to switch it.

Contact the hospital promptly if you cough up blood, lose weight without trying, or have drenching night sweats or ongoing fever — these need prompt review. If you have severe breathlessness, chest pain or blue lips, call emergency services or go to the nearest emergency department.

Cost and insurance

Most UAE health insurance plans cover a specialist consultation, chest X-ray and spirometry for a persistent cough. CT scans and bronchoscopy often need pre-approval from your insurer, which the hospital can help request once the test is recommended.
