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.
