Allergic skin diseases
Allergies can manifest themselves through numerous skin changes. A specialist diagnosis allows the cause of the symptoms to be identified and the most appropriate treatment to be determined.
Allergic skin diseases include a group of conditions in which the skin is the primary organ affected by the allergic reaction. Itching, redness, hives, swelling, eczema, and hives are common manifestations that can appear suddenly or become chronic.
Although many skin lesions appear similar, the causes can be very diverse. For this reason, an allergy assessment is essential to distinguish a true allergy from other dermatological or inflammatory conditions and develop a personalized treatment plan.
What are the main allergic skin diseases?
Allergic skin reactions can affect people of any age and present with different symptoms.
Among the most common forms we find:
Skin reactions to drugs and insect bites
Some medicines and the venom of bees, wasps and other hymenoptera can cause skin reactions of varying severity, from a simple rash to more serious reactions.
Atopic dermatitis
It is a chronic inflammatory disease characterized by dry skin, eczema, and persistent itching. It may be associated with other allergic conditions such as asthma and allergic rhinitis.
Urticaria
Urticaria is characterized by the sudden onset of itchy bumps that can affect any part of the body. Episodes can be acute or chronic and sometimes associated with angioedema.
Angioedema
Angioedema causes sudden swelling of the deeper layers of the skin, especially the lips, eyelids, face, and tongue. In some cases, it requires prompt medical attention.
Allergic contact dermatitis
It appears after contact with substances to which the immune system has developed a sensitization, such as nickel, cosmetics, perfumes, latex or preservatives.
Symptoms of allergic skin diseases
Symptoms may vary depending on the pathology and the allergen involved.
The most common symptoms include:
- intense itching;
- redness of the skin;
- pomfi;
- swelling;
- eczema;
- flaking;
- vesicles;
- dry skin;
- recurrent urticaria.
If you experience sudden facial swelling, difficulty breathing, or systemic symptoms, you should seek emergency medical attention immediately.
Allergy diagnosis
An allergy visit is the starting point for identifying the cause of skin manifestations.
During the evaluation the following are analyzed:
- medical history;
- how symptoms appear;
- foods and medications taken;
- exposure to allergens;
- work activity;
- any associated pathologies.
When indicated, the following may be prescribed:
- prick test;
- patch test;
- specific IgE dosage;
- blood tests;
- further diagnostic investigations.
A correct diagnosis allows us to distinguish allergies from other dermatological diseases with similar symptoms.
