Food intolerance is the immune reaction of the body to a particular product. As a rule, it manifests itself externally – rash, itching, hives, swelling and extreme – anaphylactic shock. The latter is associated with serious breathing difficulties and can be fatal.
Food intolerance occurs when the body can not digest a certain product (eg eg milk, eggs) due to the lack or absence of the enzyme responsible for its absorption.
This manifestation is also called “holey gut” syndrome, or irritable bowel syndrome (IBS). Thus, the stomach stops absorbing useful substances and digestive problems occur.
Symptoms – bloating and abdominal pain, gases, skin rashes, constipation and diarrhea. Hypersensitivity is much more common than allergies.
Each year, the number of people suffering from food intolerance is increasing. The situation is exacerbated by the fact that not everyone can tell the difference between intolerance and an allergic reaction. At the same time, there is food intolerance, which is very difficult to diagnose, due to the fact that the reaction to an unwanted product can occur within a few days. This type of food intolerance is observed in more than 20% of people. This type of intolerance is quite difficult to treat, because the symptoms are not immediately detected.
And because of the fact that the intolerance is not detected immediately, a person may suffer from the disease for many years and not guess about it. As a result, the disease may take a chronic form and can not be cured. People with food intolerance often suffer from obesity, gastrointestinal diseases and dermatitis.
In a healthy body, food is broken down effortlessly and sent to the blood. In the case of food intolerance, the food is not fully broken down and large macromolecules enter the blood. As a result, there are gastrointestinal diseases, allergic reactions.
Often the causes of food intolerance lie in existing problems with the gastrointestinal tract, frequent stress. The cause of this disease may also be the quality of products, namely, artificial colorants and additives contained in them.
Symptoms of food intolerance
The symptomatology of food intolerance is complex and non-specific. Specialists highlight the main symptoms that occur in the first few hours after eating the product. These are systemic allergic reactions and skin.
They are systemic:
- Itching of the skin
- Tongue numbness

Skin reactions are similar in children and adults. Typically, infants have a primary reaction to the product-allergen – rashes on the skin, itching, interleavage. In adults, food intolerance is accompanied by hives or atopic dermatitis.
