Chronic Cough: When a “Simple Cough” Won’t Go Away
Most coughs clear within a couple of weeks after a cold or viral infection. But for some people, a cough persists for months — sometimes even years — becoming frustrating, exhausting, and socially disruptive.
At Hampshire ENT Clinics, we regularly assess patients with chronic cough, helping identify the underlying cause and provide targeted treatment to break the cycle.
What Is Chronic Cough?
A cough lasting more than 8 weeks is considered chronic.
Many patients assume the cause is a chest problem, but in reality a large proportion of chronic cough originates from the nose or throat rather than the lungs.
The most common ENT-related causes include:
Post-nasal drip (PND)
Laryngopharyngeal reflux (silent reflux)
Laryngeal hypersensitivity
Poor vocal hygiene or voice strain
Often more than one factor is involved.
Post-Nasal Drip (PND)
One of the most common causes of chronic cough is post-nasal drip, where excess mucus from the nose or sinuses drips down the back of the throat.
Typical symptoms include:
Constant throat clearing
A sensation of mucus in the throat
A tickling or irritation triggering cough
Worse symptoms when lying down
PND can be caused by:
Chronic rhinitis
Allergies
Sinus inflammation
Overactive nasal nerves
Modern Treatment: ClariFix®
For patients with persistent post-nasal drip that does not respond to medication, ClariFix® cryotherapy may be an option.
This modern treatment:
Targets the overactive nasal nerves responsible for excessive mucus production
Is performed using local anaesthetic or general anaesthetic
Can significantly reduce chronic nasal drip and cough
Many patients notice a lasting improvement in symptoms.
Reflux (Silent Reflux / LPR)
Another very common cause of chronic cough is laryngopharyngeal reflux (LPR), sometimes called silent reflux.
Unlike classic heartburn, LPR often causes symptoms in the throat rather than the chest.
Common symptoms include:
Persistent cough
Hoarseness or voice change
A lump sensation in the throat (globus)
Frequent throat clearing
Irritation when speaking
Reflux irritates the voice box (larynx) and can make the cough reflex extremely sensitive.
Treatment may include:
Dietary and lifestyle changes
Medication to reduce acid
Voice therapy and behavioural strategies
Vocal Hygiene and Laryngeal Sensitivity
Over time, chronic coughing can make the throat hypersensitive, meaning even minor irritation triggers another cough.
Poor vocal hygiene can worsen this cycle.
Helpful measures include:
Staying well hydrated
Avoiding throat clearing
Reducing caffeine and alcohol intake
Managing reflux triggers
Using voice therapy techniques
Breaking the cough reflex cycle is often a key part of treatment.

When Should You Seek Help?

Final Thoughts
Chronic cough can be incredibly frustrating, but in many cases the cause is identifiable and treatable.
Addressing issues such as post-nasal drip, reflux, or laryngeal sensitivity can dramatically improve symptoms and quality of life.
If you are struggling with a cough that simply will not go away, the team at Hampshire ENT Clinics can help identify the cause and guide the most effective treatment.
Frequently Asked Questions (FAQs): Chronic Cough
What is considered a chronic cough?
A cough that lasts longer than 8 weeks is considered chronic. If a cough persists beyond this time, it is important to investigate possible underlying causes.
What are the most common causes of chronic cough?
The most common ENT-related causes include:
Post-nasal drip (PND) from the nose or sinuses
Laryngopharyngeal reflux (silent reflux)
Laryngeal hypersensitivity
Voice strain or poor vocal hygiene
Often more than one factor contributes to symptoms.
What is post-nasal drip?
Post-nasal drip occurs when mucus from the nose or sinuses runs down the back of the throat. This can irritate the throat and trigger coughing or constant throat clearing.
How is post-nasal drip treated?
Treatment may include nasal sprays, allergy management, and saline rinses. For persistent symptoms that do not respond to medication, ClariFix® cryotherapy may be an option.
What is ClariFix® treatment?
ClariFix® is a minimally invasive treatment that targets overactive nasal nerves responsible for excessive mucus production. It is performed in clinic and can significantly reduce chronic nasal drip and cough in selected patients.
Can reflux cause a chronic cough?
Yes. Laryngopharyngeal reflux (LPR), sometimes called silent reflux, can irritate the throat and voice box. This can lead to persistent cough, throat clearing, hoarseness, or a lump sensation in the throat.
What is vocal hygiene and why is it important?
Vocal hygiene refers to habits that help keep the throat and voice box healthy. Good vocal hygiene includes staying well hydrated, avoiding excessive throat clearing, reducing caffeine and alcohol intake, and managing reflux triggers.
When should I see an ENT specialist for chronic cough?
You should seek specialist advice if:
Your cough lasts more than 8 weeks
You experience persistent throat clearing
You have hoarseness or voice change
Your cough has not improved with usual treatments
How can Hampshire ENT Clinics help?
Our ENT consultants can investigate the cause of chronic cough using examination and flexible nasendoscopy. Treatment may include medical therapy, reflux management, vocal hygiene advice, or procedures such as ClariFix® for chronic post-nasal drip.
