Allergy is a reaction of the body’s immune system to substances that are normally safe for most people. In this case, the immune system perceives these substances (allergens) as dangerous and mobilizes defense mechanisms to fight them. This leads to a variety of symptoms.
Here are some of the most common types of allergies:
– Allergic rhinitis: characterized by runny nose, itchy eyes, sneezing and stuffy nose.
– Atopic dermatitis (eczema): Appears as itching, redness and inflammation of the skin.
– Allergic contact dermatitis: occurs when in contact with certain substances, causing itching, rashes and redness of the skin.
– Food allergies: can cause symptoms such as itching around the mouth, swelling of the throat, nausea, vomiting, diarrhea and urticaria.
– Allergic asthma: characterized by narrow bronchi, causing episodes of shortness of breath, frequent coughing and difficulty breathing.
