What is Psoriasis?

Psoriasis is a chronic autoimmune disease characterized by the rapid growth of skin cells that leads to scaling on the skin's surface. It is a common condition that affects millions of people worldwide and can occur at any age.

Causes

While the exact cause of psoriasis is not fully understood, it is believed to be linked to an immune system malfunction. Genetic factors also play a role, as psoriasis often runs in families. Environmental triggers such as stress, skin injuries, and certain medications can exacerbate the condition.

Symptoms

Common symptoms of psoriasis include red patches of skin covered with thick, silvery scales. These patches can appear on various parts of the body, including elbows, knees, scalp, and lower back. Other symptoms may include itching, burning, and discomfort.

Types

There are several types of psoriasis, including:

  • Plaque Psoriasis: The most common form, characterized by raised, inflamed, red lesions covered with silvery-white scales.
  • Guttate Psoriasis: Often starts in childhood or young adulthood and presents as small, drop-shaped lesions.
  • Inverse Psoriasis: Appears as bright red, shiny lesions in skin folds.
  • Pustular Psoriasis: Characterized by white pustules (blisters of non-infectious pus) surrounded by red skin.

Management

While there is currently no cure for psoriasis, various treatments such as topical therapies, phototherapy, and systemic medications can help manage symptoms and reduce flare-ups.
