Allergology in Japan

Allergology is the branch of medicine that deals with the study, diagnosis, and treatment of allergies. Allergies are the immune system’s response to substances that can be harmful to the human body (allergens). Allergens can be found in the air, certain foods, everyday objects, drugs, and pets. 

A doctor who specializes in the treatment of allergies is called an allergist, while a scientist who studies allergology is called an allergologist. They can examine allergic pulmonary and skin diseases in both children and adults. In addition, they are able to examine the ear, nose, and throat diseases that are related to allergic problems. Allergist usually works with other specialists, such as ENT (ear, nose, and throat) doctors, dermatologists, internists, or gynecologists. Some of the most common allergy that allergists can help treat include:

• Food allergies (such as peanuts, cow’s milk protein, meat, and fruit)
• Animals (such as insects and feathered or furry animals)
• Dust mites (tiny bugs that can be found in dust in carpets, mattresses, and furniture)
• Pollens (trees, grasses, herbaceous plants)
• Latex
• Mould
• Certain metals
• Sun.

The specialty of adult allergology focuses on the treatment of atopic eczema and urticaria, asthma and obstructive pulmonary diseases, chronic maxillary sinusitis, allergic eye symptoms, as well as drug and food allergies. Pediatric allergology concentrates on treating atopic eczemas and asthma in children of all ages, in addition to food allergies and other types of allergies.

Allergists can perform a wide range of tests and procedures, including:

• Allergy skin testing, including prick skin testing and intradermal skin testing
• Food challenges
• Aspirin desensitization
• Blood tests
• Physical exam
• Spirometry (lung function tests)
• Medication/drug challenge
• Patch testing
• Allergy shots
• Prescribing medications, such as emergency epinephrine and antihistamine.

How Long Should I Stay in Japan?

You should be able to leave the clinic or hospital on the same day as your allergy test or treatment. However, it is advisable that you stay at least 2 to 3 days after an allergy test to wait for the results. You will need to visit your allergist who will explain the results to you and discuss the best treatment option. If you need allergy shots, you usually require them every 2 to 4 weeks for 4 to 5 months. You can choose to travel multiple times or stay in Japan until the whole treatment is finished.

What's the Expected Recovery Time?

There is little to no recovery times after allergy tests or treatments. You should be able to resume your normal activities as soon as you do not experience symptoms that interfere with your ability to perform your daily activity.

What Aftercare is Required?

Your doctor will give you instructions to prevent an allergic reaction from happening in the future, which usually includes avoiding your allergens. In some cases, they will give you an emergency epinephrine autoinjector and teach you how to use it. Make sure to keep the product near you at all times. You may also be advised to let your family, friends, or those closest to you know where you keep the epinephrine and how to use it. 

What's the Success Rate?

Diagnosis and treatment of allergy are becoming more successful and safer now thanks to the continuous advancement of allergology. For example, around 85% of people who receive regular allergy shots for 3 to 5 years, experience permanent results. Medicines can also control the symptoms much better now. However, some types of treatments do have side effects and risks, such as reactions that appear as hives at the site of the injection, redness, nasal congestion, sneezing, and itchy skin.

Are there Alternatives?

In most cases, you will need to see an allergist diagnose and treat allergy, but you can also see an immunologist as the alternative. If your symptoms are found to be caused by other problems unrelated to allergy, your allergist will refer you to the relevant specialist.
