Understanding Psoriasis Symptoms, Causes, and Types

Psoriasis is a chronic skin condition that affects millions of people worldwide. If you or someone you know has been diagnosed with psoriasis, you might have questions about what it is, why it happens, and how to manage it. This article will help you understand psoriasis in simple terms, covering its symptoms, causes, types, and ways to improve your quality of life.

What is Psoriasis?

Psoriasis is an autoimmune condition where the immune system mistakenly attacks healthy skin cells, causing them to multiply too quickly. Normally, skin cells grow and shed over weeks, but in psoriasis, this process happens in just a few days. The extra skin cells build up on the surface, forming thick, scaly patches that can be red, itchy, and sometimes painful.

While psoriasis is not contagious, it can be a lifelong condition with periods of flareups and remission. The good news is that with proper care, psoriasis can be managed effectively.

Common Symptoms of Psoriasis

Psoriasis symptoms can vary from person to person, but some common signs include:

  • Red, raised patches of skin (plaques) covered with silvery white scales
  • Dry, cracked skin that may bleed
  • Itching, burning, or soreness around affected areas
  • Thickened or pitted nails (in some cases)
  • Swollen and stiff joints (if psoriatic arthritis develops)

These symptoms most commonly appear on the scalp, elbows, knees, and lower back, but they can occur anywhere on the body.

What Causes Psoriasis?

The exact cause of psoriasis is still being studied, but experts believe it results from a combination of genetic and environmental factors. Some key triggers include:

  • Family history – If a parent or sibling has psoriasis, you may be more likely to develop it.
  • Immune system dysfunction – The body’s defense system mistakenly attacks healthy skin cells.
    Stress – Emotional or physical stress can trigger flareups.
  • Infections – Strep throat or skin infections can worsen psoriasis.
  • Skin injuries – Cuts, burns, or bug bites may trigger new patches (Koebner phenomenon).
  • Weather changes – Cold, dry weather often makes symptoms worse.
  • Smoking and alcohol – These can increase the risk and severity of psoriasis.
