Dx w/ contact allergy to asteraceae fam of plants (lettuce, artichoke, sunflower, dandelion). Should I also not eat even if no prob noticed in past?

Food allergy: Patch test is used to diagnose contact allergy. If what you say is correct, you must have food patch testing, but not food prick testing. Food patch test is used to help diagnose immune cell mediated food allergy. If you ate those before without problems, you can eat those foods again. Testing for food allergy should only be done when patient is suspected to have food allergy related symptoms.

What is allergy?

Allergy: Is an exaggerated immunological reaction (sneezing, difficulty breathing, itching, skin rash) to substances (pollen, animal dander), situations or physical states that do not produce similar effects in most people. It can also be defined as altered bodily reactivity to an antigen when a person is first exposed, such as to bee venom, that is so severe that a second sting may be fatal. Hope this helps

What is an allergy?

Abnormal reaction: An allergy is an abnormal, incorrect reaction of the immune system against substances we are exposed to in our environment. This includes environmental exposures, foods, drugs, etc. Allergies must be differentiated from other reactions not mediated specifically through the immune system including irritants, intolerance, etc. In general, allergy involves the respiratory tract, skin, or GI system.

What causes allergy?

Immune reaction: Your immune system normally makes igg antibodies that recognize foreign proteins. In patients with allergy, the immune system switches to making a ige antibodies for certain proteins.

Are allergies inherited?

Are allergies inherited?

Yes.: Yes, we do see allergies in families. Your risk of allergies increases if one parent has allergies, and is even higher if both parents suffer from allergies. Interestingly, we are seeing that exposure to allergens may also play a part in the development of allergies in children. Rural areas, with high levels of plant and animal allergens, actually have lower levels of allergic disease in kids.

Are allergies heredity?

Are allergies heredity?

Is a strict sense no: Allergies do travel in families but the genetics and heritability of allergies is very complex. With two allergic parents, it is a 50/50 chance that a child would be allergic. What is passed on is the ability to be allergic not a specific allergy or a specific manifestation of allergy.

Will allergy shots work?

Will allergy shots work?

Yes: Allergen immunotherapy (allergy shots) is effective for most people and is the only "disease modifying" treatment available. In general about 30% of patients have great response, 30% have good response, 30% have a fair response and unfortunately 10% don't respond. There is no way to predict how good the response will be. It's excellent and safe therapy in the right hands (an allergist).
