Why Am I Suddenly Allergic to Red Meat? The Tick Bite Nobody Warns You About

Alpha-gal syndrome is an allergy to alpha-gal, a sugar found in cows, pigs, sheep, deer, and other mammals. It is not found in humans, poultry, or fish.

In the United States, alpha-gal syndrome is most commonly associated with the lone star tick. After a bite, your immune system may begin producing antibodies that react to alpha-gal. This can cause an allergic reaction after eating beef, pork, lamb, venison, or other mammal-derived products—even if you have eaten them safely for decades.

Unlike most food allergies, alpha-gal symptoms are delayed. Reactions usually begin two to six hours after eating. You could eat a burger for dinner and wake up during the night with:

● Hives, itching, or swelling
● Stomach pain, nausea, or diarrhea
● Coughing, wheezing, or difficulty breathing
● Dizziness or fainting
● Anaphylaxis in severe cases

Some people experience only digestive symptoms and assume they have reflux, a food intolerance, or irritable bowel syndrome.

Stop guessing about which foods are making you sick. We can evaluate your symptoms, food history, and test results to help identify possible allergic triggers.

Contact Primary Prevention Center today to schedule your IgE Allergy Explorer with Alpha-Gal.

IgE stands for immunoglobulin E, an antibody produced by your immune system in response to an allergen.

The IgE Allergy Explorer with Alpha-Gal is a blood test that looks for IgE antibodies associated with alpha-gal and other food allergens. Testing may help determine whether an allergic immune response is contributing to your symptoms.

Results should always be interpreted with your symptoms, the timing of your reactions, and possible tick exposure. A positive result shows sensitization but does not confirm alpha-gal syndrome by itself.

It May Be More Than Red Meat

Possible triggers can include:

● Beef, pork, lamb, and venison
● Bacon, sausage, hot dogs, and meat-based gravies
● Gelatin and animal fats
● Dairy products in some people
● Certain medications, supplements, and capsules

If alpha-gal syndrome is suspected, do not intentionally test foods at home. Reactions can be unpredictable and potentially life-threatening.
