What is Alpha-Gal Syndrome?
Source: CDC
Alpha-gal (galactose-α-1,3-galactose) is a sugar molecule found in most mammals.
Alpha-gal is not normally found in fish, reptiles, birds, or people.
Alpha-gal can be found in products made from mammals (including some medications, cosmetics, vaccines, gelatin, and milk products).
There is evidence that the alpha-gal molecule is found in the saliva of certain types of ticks.
What is alpha-gal syndrome (AGS)?
Alpha-gal syndrome (AGS) (also called alpha-gal allergy, red meat allergy, or tick bite meat allergy) is a serious, potentially life-threatening allergic reaction. AGS may occur after people eat red meat or are exposed to other products containing alpha-gal.
What are the symptoms of AGS?
AGS reactions can include:
Rash
Hives
Nausea or vomiting
Difficulty breathing
Drop in blood pressure
Dizziness or faintness
Severe stomach pain
Symptoms commonly appear 3-6 hours after eating meat or exposure to products containing alpha-gal (for example, gelatin-coated medications).
AGS reactions can be different from person-to-person and can range from mild to severe or even life-threatening.
If you think you may have AGS go talk to your healthcare provider.
People may not have an allergic reaction after every alpha-gal exposure.
