Beware of PM 2.5 Triggering “Allergy” – Treat Chronic Nasal Congestion in Winter with Radiofrequency


Many areas in winter in Thailand face health issues like the emergence of PM 2.5. Recently, the air quality in many areas in Bangkok has exceeded the standard safety, which may trigger symptoms of chronic allergies or rhinitis in those who have these diseases.

The toxic particles in air pollutants affect both the upper and lower respiratory tracts. The allergy symptoms may look like those of common dust allergies, such as sneezing, tickle in the nose, runny nose and postnasal drip.

Some patients may also have rhinitis which causes sores in the nose that leads to bleeding. This heavily affects patients with allergies or nasal congestion.

To be taking care of health during the emergence of PM 2.5 in the air, people who have chronic allergies should avoid outdoor activities, use respiratory protective equipment, perform nasal irrigation to wash away the dust that adheres to the mucous membrane and continue using allergy medications. In case the symptoms worsen, see a doctor to receive the right course of treatment.

In case patients do not respond to medications or have nasal congestion due to inferior turbinate hypertrophy, a technology called “RF or Radiofrequency” is used to treat the disease.

Radiofrequency is done by inserting a special needle into the nasal cavity. The radiofrequency will be transformed into thermal energy, causing the nasal turbinate to shrink. This creates more space in the nasal cavity, allowing the patient to breathe more easily.
