Sinusitis (or rhinosinusitis) is a common condition caused by inflammation of the sinuses, often alongside nasal inflammation. Typical symptoms include nasal blockage or discharge, facial pressure or pain, and a reduced sense of smell.

🔹 Acute sinusitis lasts less than 12 weeks and often follows a cold
🔹 Chronic sinusitis persists beyond 12 weeks and may be linked to underlying conditions like nasal polyps

🔍 How is it diagnosed and treated?

Healthy sinus function depends on open drainage pathways, effective mucus clearance, and a well-regulated immune system. Specialists assess these through detailed evaluation, including nasal endoscopy, imaging (such as CT scans), and allergy or blood testing where needed.

Symptoms are graded by severity to guide treatment, which is often medical and tailored to the underlying cause. Seeing a specialist ensures an accurate diagnosis and a personalised treatment plan based on the latest evidence.

If you’re experiencing persistent nasal symptoms, they could be a sign of acute or chronic rhinosinusitis, both of which require proper diagnosis and personalised treatment.

20/03/2026

Asthma is defined as a chronic inflammatory disease of the airways characterised by variable airflow obstruction (intermittent breathlessness as air cannot enter or leave the lungs) and associated airway symptoms of chest tightness, cough and wheeze.

Sometimes, in the most severe forms of asthma, airway narrowing remains fixed because the airway has structurally changed or remodelled. There are at least three major distinct inflammatory subtypes and a rare type termed paucigranulocytic. The latter typically has no excess inflammation and is considered driven by primary airway smooth muscle dysfunction, leading to bronchospasm.

Approximately 5-10% of asthma patients have treatment-refractory, severe, and debilitating disease. Unfortunately, allergic rhinitis and chronic rhinosinusitis are commonly associated with asthma. Treating sinonasal disease improves asthma control and treatment outcomes.

Expert care is available at London Allergy Nose and Sinus Clinic (LANSC). Dr. Harsha Kariyawasam, our lead physician, has particular expertise in asthma diagnosis and matching the right treatment to the right asthma subtype, which is termed precision medicine. With a PhD in allergy and asthma and subspecialist expertise in rhinitis and sinusitis, Dr. Kariyawasam integrates both upper and lower airway care. Rather than seeing an individual Allergist, ENT and Respiratory Medicine specialist, he can provide triple-specialty care for his asthma patients at any visit.

At LANSC we use a personalised approach to help you better understand and control your symptoms.

A key part of this care is our Airway Function Unit, where advanced testing helps assess how your airways are working. These detailed assessments allow us to diagnose conditions more accurately and guide the most effective treatment
plan.

Tired sneezing, an itchy, runny nose that is blocked? Having the feeling of a head cold in Spring or Summer or with dusty environments?

Nearly 30% of the UK population can suffer from nose allergy termed allergic rhinitis.

Long-term relief could be possible with immunotherapy at London Allergy Nose and Sinus Clinic (LANSC).

Instead of simply managing symptoms, immunotherapy works by gradually training your immune system to tolerate allergens such as pollen, dust mites, and in some patients, animal dander. Over time, this can significantly reduce the severity of allergic reactions and improve your quality of life.

At LANSC, Dr. Harsha Kariyawasam, an expert immunotherapy, provides personalised immunotherapy treatment plans designed to target the root cause of your allergies and help you achieve lasting relief.

Why consider Immunotherapy?
✔ Targets the underlying cause of allergies
✔ Can provide relief that lasts for years and sometimes even cure
✔ Helps reduce reliance on daily allergy medications


🌼 Don’t wait for the 2027 pollen allergy season to take control.
Starting immunotherapy early can make a real difference, but you need to start planning treatment now.

😖 Suffering from sinus pain, pressure, or facial congestion?

Sinusitis, whether acute or chronic, can make everyday life a struggle. It is the same as having a head-cold that never gets better, and often worse with environmental triggers. Whilst facial pain can occur with sinusitis, it is only common in acute infection related sinusitis. The clinical dilemma is facial pain/pressure or congestion if severe and if present beyond 12 weeks, is often not sinusitis but headache, commonly migraine. With migraine, nasal mucus and nasal congestion often co-exist due to the same nerves that generate pain activating nasal nerve reflexes. Thus expert review and precise diagnosis is the key step to effective treatment.

At London Allergy Nose and Sinus Clinic (LANSC), we offer expert care for sinusitis and rhinosinusitis, conditions that affect millions of people.

Dr. Harsha Kariyawasam leads our clinic with nearly two decades of experience in treating these complex conditions using advanced diagnostic tools and personalised treatments.

🌿 Struggling with Allergies? We’re Here to Help! 🌿

At London Nose and Sinus Clinic Medical (LNSCM), we’re proud to offer expert care for a wide range of allergy and respiratory conditions, from seasonal hayfever to chronic sinus issues. Led by Dr. Harsha Kariyawasam, one of the UK’s leading specialists in Allergy & Respiratory Medicine, we focus on treating the root causes of your symptoms for long-term relief.

🌟Did you know? 🌟
Tree and food pollen syndrome - also known as Oral Allergy Syndrome (OAS) - can cause cross-reactions between certain foods and tree pollen. This means that if you suffer from tree pollen allergies, you might experience symptoms like itching or swelling in the mouth after eating certain fruits, nuts or vegetables. But don’t worry, our team at LNSCM has the expertise to diagnose and manage these reactions so you can enjoy your meals without the discomfort. Through molecular component IgE measurement, we can differentiate harmless but bothersome allergy like the Oral Allergy Syndrome from more serious life threatening primary food allergy and even predict severity of an allergic event for some foods.

🌟 What sets us apart? 🌟
Dr. Kariyawasam's unique approach, combining both ENT and Allergy Medicine, helps us achieve better outcomes for complex allergy and airway conditions, like food allergy, chronic rhinosinusitis and allergic rhinitis.

✨ Our approach is holistic, personalised, and effective.
Dr. Kariyawasam’s inclusion in the 2026 Tatler Doctors Guide is a clear reflection of his exceptional expertise and commitment to advancing Allergy & Respiratory Medicine. This recognition highlights his outstanding contributions to the field and the high standard of care he provides to his patients. 🙌

• What hayfever is and why symptoms occur

A new era in anaphylaxis care is here 💙

EURneffy is the first needle-free intranasal adrenaline treatment approved in the UK for the emergency treatment of anaphylaxis.

Until now, adrenaline could only be given via injections such as Adrenaline Auto-Injectors (AAIs) like EpiPens. With EURneffy, patients now have greater choice in both device and delivery route.

Why EURneffy is a game-changer compared to AAIs:

✔️ Needle-free nasal spray – ideal for those with needle phobia
✔️ Simple and quick to use in an emergency
✔️ Rapid absorption through the nasal lining, even if the nose is congested
✔️ Comparable effectiveness – delivers adrenaline levels similar to a standard 0.3 mg injection
✔️ More portable & heat-stable than traditional auto-injectors
✔️ Supplied as a pair in a small, easy-to-carry case, allowing a second dose if needed after 5 minutes.

Key facts:

• Approved by the MHRA in July 2025
• Suitable for adults and children weighing 30 kg or more
• Available on the NHS and via private prescription
• Used for severe allergic reactions caused by foods, insect stings, medications and more.

At London Nose and Sinus Clinic Medical, patients can discuss whether EURneffy is a suitable option as part of their personalised allergy care with one of the UK’s leading Consultants in Allergy and Respiratory Medicine, Dr Harsha Kariyawasam.

✨ New Year. Fewer Allergies. Better Breathing. ✨

Struggling with hayfever or year-round allergy symptoms? This January could be the start of lasting relief.

Immunotherapy (allergy desensitisation) treats the root cause of allergic rhinitis, not just the symptoms. By gradually retraining your immune system, it can significantly reduce sneezing, congestion, itchy eyes, poor sleep, and even help improve allergy-related asthma.

Consider the benefits:

✔ Long-term relief (not just temporary symptom control)
✔ Effective for pollen & house dust mite allergies
✔ Can improve nasal, eye & chest symptoms
✔ Reduces reliance on antihistamines and sprays
✔ Proven to reduce symptoms by up to 60–70%

Before starting immunotherapy, it’s important to identify which allergens are causing your symptoms. This is done through skin prick testing or specific IgE allergy blood tests.

If allergies are holding you back, make 2026 the year you take control.
