How do urticaria occur?
The main cause of hives is through an allergic reaction . When this takes place, the body reacts through the immune system, the one in charge of defending us against diseases. In this case, the immune system makes the antibodies bind to the allergen that has invaded our body. The antibody that plays a major role in hives and most allergies is immunoglobulin E. This involves the activation of 2 primordial cells that release histamine into the bloodstream, causing itching and swelling.
The types of urticaria according to evolution are the following:
- Acute urticaria. The duration of symptoms is less than 6 weeks.
- Chronic urticaria. Lesions remain for more than 6 weeks.
- Intermittent hives
Causes of hives
In general, when an acute urticaria occurs, the one that usually disappears in a few hours, is usually related to foods such as:
- Dairy products such as: milk, cheese, yogurt.

However, the main cause of hives are certain medications such as penicillin and other antibiotics, aspirin, among others.
Hives can occur in the following situations:
- Person who when he comes into contact with an element that causes him allergy, suffers the release in his body of the substances that cause hives. This takes place in the case of food, medicines, some materials such as latex and insect bites.
- Respiratory or gastrointestinal infections, very common in children.
- By some bacteria, food chemicals or blood transfusions.
- As a reaction to cold temperatures, by rubbing, contact with sunlight or while doing sports.
Symptoms of hives
The most frequent signs that indicate that we may suffer from this allergic reaction are the following:
- Edema: swelling in some area of the skin’s surface.
- Pruritus: itching, which can vary in intensity.
- Erythema: redness of the affected skin area.
It is also possible that the condition occurs in the mucous membranes and the dermis, one of the layers that makes up the skin. In this case it is angioedema , which occurs under the surface of the skin.

On the other hand, if it is detected that the condition is serious, affecting breathing or that angioedema exists, the patient is treated with corticosteroids (Urbason) in order to combat it. The use of adrenaline or steraids may also be required in cases where, for example, inflammation in the throat occurs with the risk of obstructing the airways.
