fémallergia

Fémallergia, also known as nickel allergy, is an adverse reaction to nickel, a metal commonly used in jewelry, coins, and various industrial applications. The condition is characterized by an immune system response that causes inflammation and irritation in the skin, often resulting in redness, itching, and swelling. Fémallergia typically affects the skin, but it can also manifest in the mucous membranes, leading to symptoms such as mouth ulcers or throat irritation.

Nickel allergy is more common in women, particularly those who wear jewelry, and it is often triggered by prolonged exposure to nickel-containing products. The diagnosis of fémallergia usually involves a patch test, where a small amount of nickel is applied to the skin and observed for a reaction. Treatment options include avoiding nickel-containing products, using nickel-free alternatives, and in severe cases, topical corticosteroids or antihistamines.

The prevalence of fémallergia has been increasing in recent years, likely due to the widespread use of nickel in consumer products and the growing awareness of the condition. It is important for individuals with fémallergia to be vigilant about their exposure to nickel and to seek medical advice if symptoms persist or worsen.
