Psoriasis is a chronic, non-contagious skin condition with different types. **Plaque Psoriasis** causes “red patches with silvery scales,” while **Guttate Psoriasis** appears as “small, drop-shaped spots.” **Pustular Psoriasis** leads to “red skin with pus-filled blisters,” **Inverse Psoriasis** affects moist skin folds, and **Erythrodermic Psoriasis** is a severe emergency, causing “widespread redness and peeling.”

The condition results from immune system dysfunction, where “T-cells attack healthy skin cells,” combined with genetic factors. Triggers include “alcohol, certain medications, and infections.”

Doctors diagnose psoriasis through a physical exam and, in some cases, a biopsy. While there’s no cure, treatments help control symptoms and improve quality of life.
