Hi doctor,

I am a 19-year-old male. My IgE levels in the past two years were 1411 and 869.0 IU/mL respectively. Do I need to check now? Also, the absolute eosinophil counts were 800 and 240. My TSH was high and it got treated. I feel allergic to dust, eggplant (tongue itch), perfume, fragrance, etc. I cannot apply any face cream. If I do then my eyes become watery instantly and do not stop for hours. I also get a burning sensation. I have acne-prone skin. Now, my main complaint is an occasional unexplained cough for more than two years. I used to avoid chill water and cold drinks. What should be done further? I have also attached my blood report of TSH and lipid profile for your reference.



Welcome to

It seems you do have allergy tendencies in your body which are associated with asthma or allergic bronchitis and high IgE levels. Also you have associated skin issues like urticaria or atopic dermatitis which are all connected together.

Well, the first line is usually anti-allergics and that too for a long time. I will not suggest Montelukast. Take Allegra 180 mg (Fexofenadine) and Levocet 10 mg (Levocetirizine) in the morning. If not controlled we can add Atarax (Hydroxyzine). The key is to suppress the allergic cell release. If not controlled you may need a short course of steroids. Steroids work like magic in these diseases, but it is bound to relapse once you stop it. So, we have to control it with all three generations of different antihistamines. These conditions tend to fade off when you reach mid 20's. At times they linger on. We have to just wait and see. But for now, we have to control the allergic storm.

Hi doctor,

Thank you for your opinion. Is any specialized test or allergy panel test required? What are the things I should avoid? Also how do I know that I am allergic to some specific thing? In case it turns out to be chronic, hence the queries. Elevated IgE in my case could be a congenital defect or affected by environmental or lifestyle factors?



Welcome back to

Pertaining to your queries my answers are as follows:

  • The allergy test is not specific. It detects lot of things which are uncalled for and you may not be able to avoid in your usual life, thus making things more stressful. For example, even cockroach dust is tested in some tests. So, you can imagine.
  • As for allergies, it is best detected by your exposure and response. You are the best judge of it and you can know about it when you experience certain symptoms. For example simple thing like prawns. People know when they are allergic to it.
  • IgE levels are both congenital and triggered by environmental agents. It has been present since birth, but got triggered by certain environmental agents.
