What does a sweet allergy look like in children

allergija na sahar - 9Allergy to sweets occurs mainly in children, but less often it manifests itself in other categories of the population. When the first signs of individual intolerance appear, it is important to identify the product that caused such a reaction of the body, to diagnose it, and to prescribe the appropriate treatment.

Main symptoms

For an accurate diagnosis, it is important to know what a sweet allergy looks like. Usually, allergies are manifested by the following main symptoms:

  • Itching, redness, rash and peeling of the skin,
  • swelling of the face and lips,
  • stomatitis,
  • allergic rhinitis, nasal congestion,
  • Quincke’s edema in especially severe cases.

The first 3 symptoms are most often observed. In this case, the signs may not appear immediately, but some time after the use of sweets, cakes or other sweets.

Sometimes a sweet allergy is confused with diathesis, dermatitis, or hives. An allergist will be able to distinguish these diseases, who will then prescribe the appropriate therapy.

But a characteristic symptom of allergies can be considered the onset of symptoms immediately after eating sweets.


When an allergen first enters the human body, the immune system begins to produce a specific protein – type E immunoglobulin.

At this stage, there are no signs of an allergic reaction to sweets. When the allergen re-enters the body, mast cells are activated, which are one of the components of the neuroimmune system.

When stimulated with immunoglobulin E, histamine is released, which causes an immediate allergic reaction.

Allergy occurs not to the sweet itself, but to its individual components. So, sucrose and fructose are considered one of the allergens. In addition, honey allergy is considered one of the strongest types of allergic reactions.

The irritating factor in this case is plant pollen. Allergy can be to other components of the sweet: lactose, maltose, dye. Nuts and cocoa, which are popular allergens, are often added to sweets or chocolate.

Also, the cause of allergy to sweets can be a violation of the digestive processes responsible for the digestion of sugar-containing foods.

With a lack of amylase, an enzyme responsible for the breakdown of carbohydrates, fermentation processes occur in the intestine. Intermediate decay products enter the circulatory system and, in large quantities, contribute to the occurrence of individual intolerance.

There are additional factors that increase the risk of allergies several times:

  • Excessive consumption of fast carbohydrates.
  • Genetic predisposition.
  • Changes in hormonal levels during pregnancy, due to menopause, taking hormonal drugs and a number of other reasons.
  • The impact of industrial waste and tobacco smoke on the body.

It is possible to establish the correct diagnosis and determine the exact allergen only after a comprehensive examination of the body. There are several methods for this.

Detonic – a unique medicine that helps fight hypertension at all stages of its development.

Detonic for pressure normalization

The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.

Detonic not addictive and withdrawal syndrome, since all components of the product are natural.

Skin tests

The method allows you to determine which allergens cause signs of the disease in a person. Skin tests are done with an injection or micro-scratching.

During testing, the body reacts to a foreign substance: histamine begins to be produced. This indicates the presence of an allergy to a specific substance, in particular, to sweets.

Attention: after the tests, slight swelling and redness of the skin, other signs of allergy in a mild form are possible.

Specific Antibody Testing

This type of analysis allows you to isolate a whole group of causal allergens. The sample for analysis is blood from a vein.

Elimination test

The elimination test is carried out with constant contact of the body with the allergen. Elimination is the temporary removal of the allergen.

With the elimination diet, sweets are completely excluded from the diet for a certain period of time, usually 1-2 weeks. If, after excluding sweets from the diet, there is an improvement in the condition, then it means that it is the true cause of allergies. Additional tests are usually prescribed.

Provocative test

An analysis is prescribed only if the cause of the allergy is unclear even after a skin test. In this case, a small amount of the substance is injected into the area under the tongue or bronchi, an immediate reaction to the body’s allergen is considered.

The test is quite dangerous, because it can cause severe allergies, so it should be carried out strictly under the supervision of a doctor.


When all the symptoms of intolerance are found, the first thing to do is to eliminate the immediate allergen (sweet) from the diet. A complete rejection of sweets helps to get rid of negative symptoms, both in a child and an adult.

Treatment can be supplemented with antihistamines, which block the production of histamine and prevent allergies from developing. It is better to choose drugs of the third or new generation, because they have the most pronounced effect and almost do not cause side effects.

But the funds of the first or second generation often cause numerous side effects: drowsiness, irregular heartbeat, headaches, high or low blood pressure. This therapy helps to quickly relieve itching, redness and swelling.

If antihistamines do not help, then hormone therapy may be prescribed for the allergic person. But hormones can be treated only in severe cases or in case of complications.

It is possible to cure an allergy to sweets completely or by 90% only by taking allergen-specific immunotherapy. This method is based on the introduction of an allergen substance into the body in small portions.

Gradually, the amount of the introduced allergen increases, and the body gets used to the once foreign substance, and a negative reaction to it no longer occurs.

Specific immunotherapy involves long-term treatment (at least a year), usually at the end of the first year, positive dynamics are already observed, but the full course lasts 3-5 years.


Unfortunately, there is no specific prevention of allergies. If you have a genetic predisposition, it is important to eat sweets as little as possible or eliminate them entirely, and also be monitored regularly by a specialist allergist.

After detecting the symptoms of allergy to sweets, the question arises of what to do next and how to treat the disease. Remember that only a competent doctor can identify the true cause of allergies and prescribe competent treatment.
