The Basics of Psoriasis: What Is It Really?
Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. These skin patches are typically red, itchy, and scaly. While the exact cause of psoriasis remains unknown, it's believed to be related to an immune system problem with T cells and other white blood cells, called neutrophils, in your body.
Why Does Psoriasis Happen?
-
Genetic Factors: If one of your parents has psoriasis, you have a 10% chance of developing it. If both parents have it, the risk increases to 50%.
-
Immune System Malfunction: Psoriasis is an autoimmune condition, where the immune system attacks healthy cells by mistake.
-
Environmental Triggers: Stress, smoking, heavy alcohol consumption, and certain medications can trigger psoriasis or make it worse.

There are several types of psoriasis, each with unique characteristics:
-
Plaque Psoriasis: The most common type, characterized by dry, raised, red skin lesions covered with silvery scales.

Guttate Psoriasis: Often starts in childhood or young adulthood, characterized by small, water-drop-shaped, scaling lesions.

Inverse Psoriasis: Causes bright red lesions that are shiny and smooth, typically found in body folds.
