Diagnosis and treatment of alpha-gal syndrome

What is alpha Gal syndrome?

Alpha-gal syndrome, also known as alpha-gal allergy, is an immunological reaction of the body to the carbohydrate alpha-galactose, which is found in certain meat products. People with this allergy can develop an allergic reaction after eating meat from mammals such as beef, pork or sheep. This reaction can range from mild symptoms such as a skin rash and stomach discomfort to more severe symptoms such as anaphylaxis. This allergy is often caused by a tick bite, as ticks can transmit the alpha-gal molecule.

Some people develop the allergy after a tick bite, especially from the lone star tick in the US. Avoiding tick bites is important as the allergy may subside if no further bites occur.
