I have been diagnosed with allergic asthma my ige was above 700 the range is 0-100. I wanted to know if high ige can be caused by food allergens such as dairy,wheat,soy etc. Or it is only caused by pollen dander or dust etc. I dont have any hives or any skin issues except i have a red rash under my eyes(its not lupus i have ruled that out.) Other symptoms i have is chronic cough, shortness of breath and fatigue. I wanted to know why is my ige high ? Doctor's just prescribe me drugs and then tell me nothing.
