Alpha-Gal Syndrome: When a Tick Bite Changes the Way You Eat
When the tests look normal, but you don't feel normal, there may be more to the story.
By Dr. Charlie Roach, D.Ac., L.Ac., FMP
If you live in the mountains of North Carolina, you've probably heard someone talk about Alpha-Gal. Maybe you've even had a friend who suddenly couldn't eat steak. Or someone who developed hives, stomach problems or another unusual reaction several hours after eating meat. For some people, a tick bite can completely change the way they eat and live.
This condition is called Alpha-Gal Syndrome, and it is something I see with increasing frequency in our region. One of the things that makes Alpha-Gal so frustrating is that the reaction often doesn't happen immediately. You can eat a hamburger at dinner, feel perfectly fine, and then wake up several hours later with symptoms. That delay can make it incredibly difficult to figure out what's happening.
What Is Alpha-Gal?
Alpha-Gal is short for galactose-α-1,3-galactose, a carbohydrate found in most mammals.
Humans don't naturally produce it. After certain tick exposures, some people develop an immune response to Alpha-Gal and begin producing specific IgE antibodies against it. Once sensitized, exposure to mammalian products can trigger an allergic reaction.
For some people, beef, pork and lamb are obvious triggers. For others, dairy, gelatin or other mammalian-derived ingredients may also cause problems. And the severity can vary considerably.
The Tick Connection
In the United States, Alpha-Gal Syndrome is strongly associated with bites from the Lone Star tick, which is common throughout the Southeast and Appalachian region.
Not everyone who is bitten develops Alpha-Gal. But if you have developed Alpha-Gal, avoiding additional tick bites becomes especially important.
This is one reason I spend time talking with patients not only about food, but also about their outdoor environment and tick prevention.
Why Is Alpha-Gal So Difficult to Figure Out?
The timing is one of the biggest problems. With many food allergies, the reaction happens relatively quickly. Alpha-Gal can be different.
Symptoms may not appear until several hours after exposure. That means you may have no idea that the steak you ate at 7 p.m. was responsible for the reaction you experienced at midnight.
Patients sometimes spend months or even years trying to identify what is causing their symptoms. Once the pattern becomes clear, however, things can start to make much more sense.
What Can Alpha-Gal Look Like?
Symptoms can include:
Hives or itching
Flushing
Swelling
Abdominal pain
Nausea
Vomiting
Diarrhea
Gastrointestinal distress
Respiratory symptoms
Dizziness
More serious allergic reactions, including anaphylaxis
Not everyone experiences the same combination of symptoms. And if you've experienced difficulty breathing, significant swelling, fainting or anaphylaxis, this needs to be taken seriously. Emergency planning and appropriate allergy care are essential.
How Is Alpha-Gal Diagnosed?
If I suspect Alpha-Gal, one of the important pieces of the evaluation is an Alpha-Gal-specific IgE blood test. But I don't believe the laboratory result should be interpreted in isolation.
We need to look at the history.
What happened after the tick bite? What foods trigger symptoms?
How long after eating do symptoms appear?
Are there reactions to dairy or gelatin?
Have symptoms changed over time?
And has the person had additional tick exposure?
The laboratory result is important, but so is the story.
My Approach to Alpha-Gal at Root & Branch
This is where my approach differs somewhat from simply handing someone a list of foods to avoid.
SAAT (Soliman Auricular Allergy Treatment) is my front-line treatment approach for Alpha-Gal at Root & Branch.
SAAT uses specific auricular acupuncture treatment protocols designed to address the allergic response associated with Alpha-Gal.
For patients who are appropriate candidates, this is where I generally begin.
The goal is to address the Alpha-Gal sensitivity itself rather than simply telling someone, "Don't eat beef anymore." That distinction is important.
Avoidance remains an important part of keeping someone safe while we work through the condition. But my goal is to help patients move toward greater tolerance and a less restrictive life, rather than accepting permanent dietary restriction as the only option.
I also explain to patients that Alpha-Gal is an immune-mediated allergy and that responses can vary. SAAT should therefore be viewed as part of an individualized clinical approach rather than a guarantee of eliminating the allergy.
SAAT Isn't the Only Part of the Conversation
Even when SAAT is the primary treatment, I still want to understand the rest of the person.
How healthy is the gut?
What is the patient's overall nutritional status?
Are there other food sensitivities?
Are there environmental triggers?
What is happening with sleep and stress?
Have there been repeated tick exposures?
Are there other allergic or mast-cell-type symptoms?
These questions don't mean that every Alpha-Gal patient has "gut problems" or MCAS. They simply help me understand the patient's overall situation. And sometimes there are additional factors that need attention.
Food Avoidance Still Matters
One of the biggest mistakes someone can make after being diagnosed with Alpha-Gal is assuming that treatment means they can immediately go back to eating whatever they want.
I don't recommend that.
If you have known reactions to mammalian products, avoidance and safety come first. That means learning your individual triggers, reading labels, asking questions at restaurants and understanding less obvious sources of mammalian-derived ingredients. If you've had a severe allergic reaction, you should also have an appropriate emergency plan and discuss epinephrine with your medical provider.
SAAT doesn't replace emergency treatment. It is a therapeutic approach intended to address the underlying allergic sensitivity.
Don't Forget the Tick
There is another piece of Alpha-Gal that I don't want patients to overlook. Avoid additional tick bites.
If you have developed Alpha-Gal and continue getting bitten by ticks, you may be repeatedly exposing your immune system to the same trigger associated with the development of the condition.
When you're hiking, working outside or spending time in the woods, take precautions.
Check yourself.
Check your clothing.
Check your pets.
Pay attention to the areas where ticks tend to attach. Tick prevention isn't glamorous, but it matters.
You Can Still Have a Life After Alpha-Gal
An Alpha-Gal diagnosis can be overwhelming.
Suddenly you're reading every food label. You don't know whether you can eat at a restaurant. You start wondering about dairy, gelatin, medications and supplements. Food becomes something you think about constantly.
I've seen how much anxiety that can create. My goal with treatment isn't simply to give you a longer list of things you can't eat.
It's to help you understand what's happening and, when appropriate, work toward greater freedom with food.
That's why SAAT is my starting point for Alpha-Gal patients at Root & Branch. We address the Alpha-Gal sensitivity first, while maintaining appropriate avoidance and safety measures. Then we look at the rest of the picture and support the patient's overall health and resilience.
Alpha-Gal can change your life. But it doesn't have to define your life.
If you live in the Appalachian region and you've experienced unexplained allergic reactions, particularly reactions occurring several hours after eating mammalian meat, Alpha-Gal may be worth discussing with your healthcare provider. And if you've already been diagnosed, there may be more options to explore than simply accepting a lifetime of increasingly restrictive eating.
