Food Intolerance

Quite often, even when the test results are negative, complaints do not cease.  The cause behind the complaints is often chronic food sensitivity, that is, IgG mediated food intolerance.   

Symptoms of food intolerance such as general dejection, weight problems, fatigue, headaches, systemic inflammation a well as stomach and intestinal complaints usually appear only in a few days or even weeks after consumption of a particular food.

Diagnosing the Disorder

When certain segments of the intestinal wall are damaged, some foods do not break down completely and, as a result, foods that “do not belong there” pass through the damaged wall and get into the blood stream.  The body sees these as “enemy intruders” and immediately protects itself against them with the help of the immune system.

The body begins to produce specific IgG antibodies against the intruding proteins.  These appear in the blood, attach themselves to the intruders neutralizing and making them harmless.  The immune complexes resulting from the linking of the intruding proteins (antigens) and the invading IgG antibodies - as the result of a complicated process - may evoke food intolerance and cause the related symptoms.

Main Symptoms

This process differs from food allergy that affects a small (2-5%) percentage of the population and causes intense symptoms a short time after food consumption.  Allergy is caused by the over-reaction of the immune system to substances that in a healthy person do not cause any reaction.  Classic allergy is principally caused by an immune reaction in which both the mast cells and the IgE antibodies are involved. 

Food intolerance is much more prevalent than food allergy with about 15-30% of the population suffering from the disorder.  The inflammatory process accompanying food intolerance causes slow, drawn out and latent symptoms.  According to a Hungarian survey, one-half of food intolerance sufferers have irregularly manifesting digestive system complaints (stomach and abdominal cramps, nausea, diarrhea, constipation) and about one-third have complaints of skin problems (erythroderma, rash, eczema). 

Besides the above, there are frequently appearing problems affecting the quality of life (i.e., headaches, sleeplessness, depression) for which no disorder treatable with medication can be found even with the most thorough examination.

On the other hand, the most prevalent symptoms of food allergy - the production of IgE antibodies - is the sudden appearance of the most common urticaria and whole body oedema which may also be accompanied by the life threatening oedema of the throat.

Examinations and Tests

Due to the general symptoms manifested, you will first undergo a physical examination to rule out other possible disorders.  This will be followed by a blood test.  Intolerance to 30 or even 120 food proteins can be determined by a single drawing of blood. 

Treatment

It has been found that when a person suffering from a disorder did not respond to treatment and a food intolerance diet was introduced as a supplementary treatment, the symptoms generally improved and often ceased altogether.    

A pediatric neurologist while treating epileptic children who did not respond as expected to the accepted therapy, found that when the treatment was supplemented with a diet, the epilepsy treatment was much more successful.

Our experienced gastroenterologists and internists as well as dietitians would be happy to help you.  Food intolerance examination for 30, 60, or even 120 allergens may be determined through a single blood drawing.
