Dr. Liu, otorhinolaryngologist specialist at Shanghai Jiahui International hospital kindly accepted to answer our questions about allergies and give us some tips to overcome allergic rhinitis.

Allergy is a hypersensitive disorder of the immune system. It means your body has overreactions to allergens. There are four types of allergic reactions and among them, allergic rhinitis is type I.

The first time a person is exposed to a type of allergens, the body does not show any allergic symptoms. However, B cells in your immune system will produce corresponding specific antibodies, called IgE. When you encounter this unique allergen again, it will combine with IgE, leading to extensive mass cell degranulation, releasing a variety of transmitters, and therefore resulting to a series of allergic reactions.

Actually, we cannot prevent or cure allergies. What we can do is to prevent or control the allergic reactions. Patients usually feel like their allergies are gone when they do not experience any symptoms.

Due to China’s vast territory, seasonal allergies vary from locations. Different regions have different allergens. The best way to protect yourself is to first do an allergen test.


By doing so, it can exactly tell you what kind of allergens you are allergic to. After knowing the allergen types, you can choose to avoid them physically in order to prevent allergic reactions. Wearing masks or avoiding areas with high concentrations of the specific allergen can be helpful.

Sneezing, runny nose, itchy nose and nasal obstructions will be presented. Some severe cases may company with other symptoms like asthma, itchy eyes and skin lesions.

A multi-centre study shows that in 2011, the prevalence rate of allergic rhinitis in China is 17.6%. This number shows that every 1 of 5 person in China will have allergic rhinitis.

At Shanghai JIAHUI International hospital, we have 4 different methods for coping with allergic rhinitis:

1. Physically keeping the allergens away from your body.

Firstly, use a nasal mucosal blocker. Other than wearing masks or moving away from certain areas, nasal mucosal blockers have been largely used because they can create a physical film to prevent allergens from being inhaled in
