Alpha-Gal Info
Alpha-gal syndrome (AGS) is a serious, potentially life-threatening allergy and tick-borne disease. Alpha-gal is a molecule (galactose-α-1,3-galactose) that is naturally produced in the bodies of most mammals but not in people. It is also found in the saliva (spit) of some ticks.
When a tick bites, it can transfer alpha-gal from its saliva into a person's blood. The body's natural defenses, or immune system, can identify alpha-gal as a threat and trigger an allergic reaction. Symptoms occur after people eat red meat or are exposed to other products made from mammals. Because of this, AGS is also known as a red meat allergy or a tick-bite meat allergy.
