For some years, emergency doctors and allergists were puzzled by people who started having extremely serious allergic reactions in the middle of the night, a long time after they had eaten or drunk anything or had any contact with obvious allergens. Smart sleuthing from our guest and his colleagues determined that a tick bite can set a person up for an unusual hours-delayed allergic reaction to eating beef, pork, lamb or any other type of mammalian meat. We call this type of reaction after the bite of a lone star tick an alpha-gal allergy. People with this condition have to avoid red meat. Some of those who suffer from it say that they can’t even drink milk or eat cheese.
Dr. Scott Commins was part of the original research team that identified this problem. He can explain exactly what is going on and why people may react in such varied ways to an alpha-gal allergy. If you have experienced alpha-gal and you have questions about it, Dr. Commins can answer them.
Have you ever had an allergic reaction to an insect sting? What should you do about it? Ask Dr. Commins for advice on this common summertime hazard.
We will also discuss a few of the other concerns that may arise around a tick bite. In addition, we’ll consider food allergies in adults and kids. The alpha-gal picture for people who are allergic to meat is unusual partly because of the delay. Most food allergies strike quickly. How should you respond? Is there a way to be prepared for an allergic reaction?
