Nahärritus

Nahärritus is a term describing skin irritation or inflammation. It is a broad category that can encompass a variety of conditions, from mild redness to more severe rashes and blisters. The causes of nahärritus are diverse and can include external factors such as contact with allergens or irritants, friction, or exposure to extreme temperatures. Internal factors can also contribute, such as certain medical conditions or reactions to medications.

Symptoms of nahärritus typically include redness, itching, burning, swelling, and sometimes pain. The appearance of the affected skin can vary depending on the underlying cause and severity. Mild cases might present as a localized red patch, while more severe reactions could involve widespread rashes or blistering.

Diagnosis of nahärritus usually involves a physical examination of the skin and a review of the patient's medical history, including any recent exposures or changes in habits. In some instances, further testing, such as patch testing for allergies, may be necessary to pinpoint the exact cause.

Treatment for nahärritus depends on the underlying cause. For irritant contact dermatitis, identifying and avoiding the offending substance is key. For allergic contact dermatitis, similar avoidance is crucial, and topical corticosteroids may be prescribed to reduce inflammation and itching. Other treatments may involve emollients to restore the skin barrier, antihistamines for itching, or, in more severe cases, oral medications. Prevention often involves protecting the skin from known irritants and allergens and maintaining good skin hygiene.
