Psoriasis is a chronic skin condition with several types: Plaque Psoriasis,
marked by red patches with silvery scales; Guttate Psoriasis, characterized by
small, drop-shaped spots; Pustular Psoriasis, featuring red skin with pus-filled blisters; Inverse Psoriasis, which affects moist skin folds;
and Erythrodermic Psoriasis, a severe, emergency condition with widespread redness and peeling.
It is not contagious. The causes include immune system dysregulation, where T-cells attack healthy skin cells, and genetic factors.
Common triggers include alcohol, certain medications, and infections. Diagnosis is through a physical exam and sometimes a biopsy.
Though incurable, treatments can manage symptoms and improve quality of life.
