Psoriasis is an autoimmune disorder that speeds up skin cell turnover, leading to scales, redness, and inflammation. It affects over 125 million people worldwide and can cause pain, sleep disruption, and difficulty concentrating. Its cause is not fully understood, but genetics and environmental factors play a role.
There are five types of psoriasis, each with unique characteristics:
- Plaque Psoriasis: The most common type, with raised, itchy patches covered in silvery scales, often on elbows, knees, and scalp.
- Guttate Psoriasis: Small, teardrop-shaped spots that appear after infections like strep throat, mostly on the torso and limbs.
- Inverse Psoriasis: Appears as smooth, shiny, red patches in skin folds, worsened by friction or sweating. It can be triggered by fungal infections.
- Pustular Psoriasis: Characterized by white pustules surrounded by red skin, often accompanied by fever or chills. It can be localized or widespread and needs medical attention.
- Erythrodermic Psoriasis: The rarest and most severe type, causing widespread redness, scaling, and shedding of skin. It can be life-threatening and requires immediate medical care.
Psoriasis can also affect nails, causing thickening, discoloration, or detachment, which may indicate psoriatic arthritis. If you notice symptoms, consult a dermatologist for proper care.
