lisäreaktiot

Lisäreaktiot, also known as allergic reactions, are the body's immune response to a foreign substance, known as an allergen. These reactions can range from mild to severe and can involve various parts of the body. Common allergens include pollen, dust mites, pet dander, certain foods, and medications.

Mild allergic reactions, often referred to as allergic rhinitis or hay fever, can cause symptoms such as sneezing, itchy eyes, and a runny nose. These reactions are typically treated with over-the-counter antihistamines or nasal corticosteroids.

More severe allergic reactions, known as anaphylaxis, can be life-threatening. Symptoms may include swelling of the throat and tongue, difficulty breathing, rapid pulse, and dizziness. Anaphylaxis requires immediate medical attention and can be treated with epinephrine (adrenaline) injections.

Allergic reactions can be diagnosed through skin prick tests or blood tests. Treatment options depend on the severity of the reaction and may include avoidance of the allergen, medication, and in severe cases, immunotherapy.

It is important to note that while allergic reactions can be uncomfortable and even dangerous, they are a normal part of the immune system's response to foreign substances. However, in some cases, allergic reactions can be a sign of a more serious underlying condition, such as asthma or eczema.

If you suspect you are having an allergic reaction, it is important to seek medical attention promptly. Early intervention can prevent complications and save lives.
