They are accompanied by typical symptoms — on the skin suddenly appear watery blisters of different sizes, which, however, go 1-2 days later. Information about this disease was first recorded in the 4th century BC by Hippocrates.

The Mechanism of development of this allergic reaction the next. When first ingested, the allergen (substance to which a person has hypersensitivity), the immune system produces a specific protein antibodies (usually IgM). They accumulate particular cells, e.g., basophils and mast cells. In these structures accumulate biologically active substances-serotonin, histamine, heparin, and others. When re-entering the allergen into the body, its molecules connect with the antibodies, and in the future — with the fat cells which causes the release of histamine and other active substances directly into the blood and tissues.

causes of urticaria in children

Of Course, for each patient, the most important issue is the successful treatment of the disease. But in order to understand how to get rid of hives, you first see the mechanism of occurrence of this pathology. Since it is an allergic reaction, the basis of its development is the contact of the immune system to the allergen. Causes of urticaria in children as well as adults can be very different. But all of them can be divided into several large groups:

  • To start is to talk about the impact of the external environment. Cold, contact with water, exposure to ultraviolet rays, radiation — all of these can cause an allergic reaction.
  • If you are interested in the most common causes of hives in children, you should pay attention to the food, as in most cases they provoke an allergic reaction in childhood. The most active allergens include nuts, honey, cocoa and chocolate, cow's milk, seafood, eggs, and some fruits and vegetables (most often people suffer from allergies to citrus and strawberry).
  • What is urticaria? Quite often it is a side effect from medication, particularly antibiotics. Very often the Allergy develops at the use of tetracycline, rifampicin, penicillins. Potentially dangerous drugs include non-steroidal anti-inflammatory drugs. By the way, the reaction can develop gradually — often the first signs of urticaria appear within 14 days after you start taking antibiotics.
  • Causes of Allergy in adults can be in contact with various aggressive chemical substances, including latex, detergents and household cleaning tools.
  • Biting insects (usually wasps, bees and hornets) can also cause a rash.

If you are wondering what hives is, you have to understand that not always the reaction is started by contact with the external environment. Quite often, the reasons may lie within the body. A weakened immune system, hormonal disturbances, goiter, autoimmune diseases, chronic fungal and parasitic diseases — all of this can be attributed to the risk factors.

Most Often, urticaria appears on the arms, legs, rarely on the back and stomach. Blisters, usually small, but sometimes can increase and reach 10 cm in diameter. By the way, more often they go after only 24 hours after appearing, leaving the skin marks (scars, age spots, spider nets).

A Second symptom of urticaria is itching, which is amplified in the evening and at night. By the way, can itch and “clean” areas of skin (no rash). Burning and soreness in this pathology do not exist. Their appearance may indicate the development of angioedema and other complications.

  • Medicinal;
  • Autoimmune;
  • Idiopathic (a diagnosis in the case if, despite all the tests that causes an allergic reaction fails to detect);
  • Infectious (Allergy develops against the background of invasion of the body by bacteria, parasites, viruses);
  • Physical Allergy (the reaction is observed under the influence of physical factors, for example, in contact with water, when exposed to a body of cold or pressure);

The analysis of the blood can be noted the increase in ESR and white blood count, and decrease in the number of red blood cells — that evidence of the abuses by the immune system.

Further tests to determine the allergen. Quite informative are the skin tests — under the skin are small doses of various groups of potentially dangerous substances, after which the reaction is monitored.
