Intolerance of food

Intolerance of food

Are you sensitive to what?

Sometimes, a few hours after a meal you feel nausea, your face is covered with cold sweat, your hands are shaking, you are upset, your heart is blinking quickly, you feel an unbearable headache, it catches you feelings of panic …

Think about what you have eaten before. It may be an intolerance to food. Namely, the symptoms of food intolerance are very unspecific and persistent, and the search for the right diagnosis is slow.

When should I suspect?

A person can hardly associate his or her problems with the introduction of some food, it continues to be kept in the usual way until the body can depreciate it. When the burden becomes too high, the defense mechanisms slow down and the reaction of “rebellion” arises in the form of various symptoms … In this way, there are numerous pathological conditions and chronic diseases for which medicine often has no real therapeutic solutions.

Symptoms of intolerance to food can occur on the skin: rash, persistent itching, hemorrhage, angioedema, eczema, psoriasis, acne. Common symptoms are swollen nose, rhinitis, sinusitis, irritation of the throat, asthma, dry cough. There are cramps in the stomach, fever in the oral cavity, nausea, gases, diarrhea, constipation and irritable bowel syndrome. Often is high blood pressure, arrhythmias, circulatory disorders occur. Problems in metabolism are elevated sugar and fat, obesity, cellulite. Hormonal disorders: clinical disorders, irregularity of the menstrual cycle are not uncommon. Neurological problems occur in the form of headache, migraine, dizziness or fainting. Loss of motivation, feeling of anxiety, lethargy, depression, fatigue, and in children in the form of hyperactivity are not uncommon, as are joints, arthritis, obesity.

Allergy or intolerance – the difference exists

Intolerance occurs due to the lack of specific chemical substances or enzymes required for digestion of food, but also due to pathological reactions to some substances commonly present in food. In practice, there is often a confusion in the diagnosis of allergy and food intolerance.

Food intolerance or nonalergic hypersensitivity to food is a delayed pathological reaction to food, drink, and food additives. Causes a variety of symptoms, not just in digestive organs.

Food allergy is an immunologic hypersensitivity that most often occurs in response to proteins of milk, eggs, seafood, shellfish, soybean, nuts, wheat and peanuts.

Food intolerance is a chronic phenomenon, often with masked symptoms and it is more difficult to diagnose than an allergy. Symptoms of intolerance vary considerably from person to person. IgE antibodies in allergy produce a clear and burning image, while intolerance symptoms occur for several hours to two days after taking food or drink.

How does the organism react to food ingredients?

The answer is: creating antibodies that, after digestion, merges with specific food antigens, forming immune complexes that create a network of so-called. circulating immunocomplexes. As a consequence, other elements of the immune system stimulate and localized inflammation of the tissue occurs, which can be manifested as well as increased permeability of the intestinal wall. A large amount of circulating immunocomplexes can increase colloidal-osmotic pressure of the blood plasma, which leads to the retention of a greater amount of fluid inside and outside the cells. The consequence is damage to different cells and tissues, but also the formation of edema with the consequence of weight gain.

The guilty lack of enzymes?

The reason for certain lack of confidence when it comes to food intolerance stemmed from the inability to determine the cause of the symptoms, or the lack of validated scientific methods of testing. However, a study conducted at the York Nutritional Laboratory suggests that the lack of a single enzyme in the body is the cause of intolerance. Enzymes are responsible for degradation and resorption of food, and due to the lack of some of them, there is an intrusion of foods into the bloodstream. The organism reacts with the development of IgG antibodies which, due to the accumulation and formation of immune complex in the blood, release toxins and other chemical substances causing delayed immune response. These “slow” antibodies occur after an organism in a food ingredient has recognized an antigen that has to be eliminated from its territory. The more antigen is, the less elimination possibility, and our antibodies, which are related to antigens, roam the organism creating problems wherever they are kept in large numbers.

How to detect “slow” antibodies?

Diagnosis is based on personal and family history and skin and serological tests to eliminate other causes. After eliminating “real” food allergies and other possible causes, a food intolerance test is initiated. This test demonstrates the pathological presence of specific IgG antibodies.

Certain groups of drugs, such as corticosteroid therapy, immunosuppressants, chemotherapy, or cytostatics, affect the immune status of the organism and may affect the test result. It is therefore a recommendation to consult a physician before testing.


In the VIZIM Health Center you can make an intolerance test on food, such as:

  • Screening test – a method primarily for patients with high body weight, undernourished people, elevated triglycerides, cholesterol, and blood glucose. In VIZIM is tested for 349 different foods.
  • Immunological test – a method intended for people with severe dermatological problems (acne, eczema, psoriasis), digestive tract problems, and respiratory organs. In the Health Center VIZIM you will get results for 90 different foods.

What after testing?

After the test, patients talk to a dietician, a doctor, a nutrition specialist who will explain the results. An unhealthy way of life, smoking and alcohol, impair the immune response in the individual, and we can expect a close connection with food intolerance. Eliminating one or more food types in more than two thirds of the cases leads to improvement, but it is necessary to listen to additional medical advice for the complete success of the therapy, and with regular controls you will achieve the desired goal.
