ABC NEWS – Alpha-gal syndrome (AGS) is a serious, potentially life-threatening allergic reaction that arises after people eat red meat or consume products with alpha-gal, a type of sugar found in most mammals, the CDC says. The syndrome is typically caused by a bite from the lone star tick, which transfers alpha-gal into the victim’s body which in turn triggers an immune system response. The CDC says the number of AGS cases are underdiagnosed in the U.S. and — despite the spread of the condition — many clinicians aren’t even aware it exists, let alone how to diagnose it.
