What is Psoriasis?
Psoriasis is a chronic skin disease. Although it does not affect overall health, the visibility of the lesions can impact the patient’s social interactions.
It is characterized by the appearance of red, scaly, inflamed plaques, sometimes accompanied by intense itching. These lesions typically appear on the scalp, elbows, knees, and lower back.
Causes of Psoriasis
Psoriasis is a chronic and recurrent skin condition caused by an abnormally accelerated renewal of the outer skin cells, leading to the accumulation of dead cells that shed as scales. The exact cause is still unknown, but there is a known genetic predisposition, along with triggering factors such as stress, infections, hormonal changes, excessive alcohol consumption, and certain medications.
Diagnosis of Psoriasis
Psoriasis is diagnosed through a clinical evaluation performed by a doctor, usually a dermatologist. During the evaluation, the doctor will examine the skin and look for the characteristic signs of psoriasis.
In addition to the physical examination, the doctor may take the following steps to confirm the diagnosis:
-
Medical history: The doctor will gather information about the symptoms, how long they have been present, and any potential triggers. They will also explore any family history of psoriasis or related conditions.
-
Skin biopsy: In some cases, the doctor may perform a biopsy of the affected skin. A small sample is taken and examined under a microscope to confirm the diagnosis and rule out other skin conditions.
In general, the diagnosis of psoriasis is based mainly on the typical appearance and distribution of the lesions. There is no specific test to diagnose psoriasis, but in more atypical or complex cases, additional tests may be requested to rule out other skin diseases with similar symptoms.
Treatment for Psoriasis
It is important to note that psoriasis is not contagious. While there is currently no cure for psoriasis, there are treatments that can help manage symptoms and reduce the frequency and severity of flare-ups. If you think you may have psoriasis, it is advisable to consult a dermatologist to obtain an accurate diagnosis and an appropriate treatment plan.
Although it has no definitive cure, early diagnosis, personalized treatment, and proper follow-up by a dermatologist can help prevent serious complications and significantly improve the quality of life for those affected.
