Alpha-gal Syndrome

by Alike Medical Team ∙ Updated on June 13, 2023

General

Alpha-gal Syndrome is a recently acknowledged condition which is characterized by allergy to red meat and other products made from mammals. It is typically caused due to the Lone Star tick bite which transmits an alpha-gal molecule to the person bitten by it. This molecule may trigger an immune reaction resulting in an allergic reaction to red meat and other mammals products. It is seen in eastern and south central United States, due to the presence of the tick there.Alpha-gal syndrome also has been diagnosed in Europe, Australia and Asia, where other types of ticks carry alpha-gal molecules.
