"The story of Sara B: A very typical "atypical" food allergy case."

Sara B. (not her real name), a 38 year old patient of Dr. Cynthia Jaffe, spent years suffering from vague digestive problems before learning that she had a gluten intolerance last year and occasional constipation or loose stool. .  In Sara's words, " I just wasn't functioning at my best.  I had no idea it was gluten that was causing me to be so tired all of the time.  I had an occasional upset stomach if I ate rich foods or something really spicy but nothing that really grabbed my attention that I had a digestive disorder.  Instead I was tired,  I had joint pain,  and occasional constipation.  The only real "digestive-like" problem was that I felt a bit of stomach bloating, like I was full often after I ate any kind of food."

What Sara is describing is a common scenario among delayed sensitivity allergen sufferers.   Vague digestive symptoms  and a feeling  that one is not functioning at their optimum level."  Those few vague conditions along with a past medical history of possible digestive problems as a child when she drank milk put Dr. Jaffe on the trail of testing Sara for food allergens. 

Celiac disease and food allergens

Dr. Jaffe tested Sara's blood for the presence of gliadin-sensative antibodies, including IgG and IgA along with antibodies that target tissue translgutaminase (tTG for short) to see if Sara had celiac disease, also known as a gluten intolerance.   Additionally, Dr. Jaffe ran a 164 IgA food allergen panel to look for sensitivities to not only the common allergens like diary, wheat, soy, and tree nuts, but also to gluten IgA along with seafood, spices, many vegetables, many different kinds of fruits, yeast, and more.   Sara came back celiac negative which ruled out the technical term of celiac disease.  However, that was not the end of the story.  Sara came back a very strong class 3 IgA allergen to gluten, confirming that her body was hostile to gluten.  She also came back with other IgA sensitivities that she needed to be aware of, for instance to yogurt, strawberries, egg yolk, vanilla, lettuce, milk (including goat's milk), brewer's yeast, and broccoli. 

Removal of allergens

The result of removing these allergens proved to be a remarkable change in how Sara has felt.  The fatigue lifted as if it was a heavy fog that once weighted her down and now had lifted off of her shoulders.  She had energy to do things she had stopped enjoying in her life because she was tired all of the time.   Sara really didn't recognize that it was such a problem until she appreciated the vast improvement not only in her energy level, but also in her ability to concentrate, the end of her constipation and a huge improvement in her joint pain.  The bonus for Sara was a "flatter" tummy.  No more bloating!  For those people with irritable bowel, or Crohn's disease, the results can be remarkable.  To live without stomach pain, and loose stools, and or medications can save these people from one day possibly needing part of their intestines removed.

What about other allergens besides gluten?

What is interesting is that even though celiac disease affects 30 percent of Americans, even more are affected by non-celiac gluten intolerance.  Many people also have an intolerance to many other foods they may have tested negative for in what is known as IgE testing or rash skin testing.

Most of us already know what we are IgE allergic to

IgE testing is going to give you a more acute reaction or more of an immediate mild to severe dermatologic, gastrointestinal or respiratory reaction that may cause you to end up in the emergency room for treatment. 

Most individuals know what their IgE allergens would be, but they often have no clue that they have an IgA reaction to a food because of its characteristic delay or sometimes milder symptomatology.  

The end result of a food allergen is destructive inflammation

The end result can be devastating in the case of either type of reaction.  The body recognizes something foreign, and stages an immune-system war against it.  The problem is that once the immune system if fired up, it is very difficult to get it to stop. Let's take Sara's mulitiple allergen's  that were revealed on testing.  The likely scenario is that when Sara was a child she was either IgE allergic or IgA sensitive to milk.  The immune system rose to the occasion to attack the protein in the milk.  But it couldn't stop itself.  It began to randomly tag other foods such as the lettuce, broccoli, yeast and so on.   And now a ripple effect occurred.  The inflammation keeps on going and began to attack her joints and was on its way to spread throughout the body.  This devastating reaction can even link to other auto-immune conditions such as lupus, rheumatoid arthritis, auto-immune thyroid disorder and even multiple sclerosis.

What do I do if I suspect a food allergen?

What to do? If you suspect that you may have a food allergen or a sensitivity, the first step is getting an accurate diagnosis.   You will need a food allergen test and perhaps other testing.  Call Dr. Jaffe and make an appointment to get testing today - 847-830-8748.
