fotosensitiivsust

Fotosensitiivsus, also known as photosensitivity or sun sensitivity, refers to an increased susceptibility of the skin to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. This heightened sensitivity can manifest in various ways, including exaggerated sunburn, rashes, or other skin reactions that occur more readily or severely than in individuals with normal skin.

The causes of fotosensitiivsus are diverse. Some individuals are born with a genetic predisposition to sun sensitivity, often associated with underlying medical conditions. Others develop fotosensitiivsus as a side effect of certain medications, including some antibiotics, diuretics, and anti-inflammatory drugs. In some cases, exposure to certain chemicals or plants can also trigger a photosensitive reaction.

Symptoms of fotosensitiivsus can range from mild redness and itching to severe blistering and pain. The specific reaction depends on the underlying cause and the individual's level of sensitivity. Photodermatoses are a group of skin disorders characterized by abnormal skin reactions to light.

Preventing and managing fotosensitiivsus primarily involves minimizing UV exposure. This includes using broad-spectrum sunscreen with a high SPF, wearing protective clothing, seeking shade, and avoiding peak sun hours. For individuals with medication-induced fotosensitiivsus, consulting with a healthcare provider about alternative treatments may be necessary. Diagnosis often involves a thorough medical history, physical examination, and sometimes specific tests like phototesting to determine the type and severity of the photosensitivity.
