Could combinations of foods cause different allergic reactions?

Possible: Anything about food allergy is likely possible but I must admit that there has been no study ,to my knowledge, addressing this issue.

What type of benadryll and how much benadryll should I give my 17 month old baby? She is also 18 lbs..She has a minor food allergy..

What type of benadryll and how much benadryll should I give my 17 month old baby? She is also 18 lbs..She has a minor food allergy..

Maybe none...: Benadryl only relieves symptoms, it is not needed just because there is an allergy. It helps if the symptoms are hives or runny nose, but likely won't help if the symptoms are diarrhea, vomiting, eczema, or asthma. The best treatment is to avoid what she is allergic to. If she does need benadryl, make sure it has no other ingredients, only diphenhydramine, and the dose is about 1/2 tsp. ...Read more

I have developed over 40 different food allergies in less than 6months. Full blood work and they can't tell me why? Its only getting worse. Help.

Be wary of labels: Some of the available skin tests are easily over interpreted as can blood tests. I suppose you didn't get labeled with many of these food allergies until the tests were done with no clear symptom patterns beforehand. Any such labels should be verified by an experienced board certified Allergist. These can happen but having been through much of this myself, I would be cautious in accepting it all ...Read more

Is a skin test for food allergies reliable? If i've tested negative can I assume that I am safe ingesting all types of foods?

Don't count on it: People can have adverse reactions to foods that are significant but have nothing to do with allergy. About 1/4 adults are intolerant to lactose sugar in regular milk & have a variety of symptoms. Red food dye #40 can give similar symptoms in many. Skin tests can be a guide, but maintaining a food diary & being vigilant about your changes in symptoms is often the best approach. ...Read more
