Psoriasis

A common, chronic immune-mediated disease that is far more than a skin rash.

What it is

A long-term immune-mediated disease

Psoriasis is a chronic disease in which an overactive immune system speeds up the skin's growth cycle, building up raised, scaly plaques. It affects roughly two to three percent of people and tends to flare and settle over a lifetime.

More than skin-deep. Psoriasis is driven by inflammation throughout the body, not just in the skin. That same inflammation is linked to disease in the joints, heart, and metabolism, so it is best managed as a whole-body condition.

Signs and symptoms

What it can look like

  • Well-defined, raised plaques with silvery or grey scale
  • Common on the elbows, knees, scalp, and lower back
  • Itching, burning, or soreness
  • Nail pitting, ridging, or lifting
  • Flares triggered by stress, infection, or skin injury

Associated conditions

Comorbidities to know

Psoriasis can travel with other conditions, which is why whole-person assessment matters, not just treating the skin.

  • Psoriatic arthritis. Joint pain, stiffness, and swelling that can cause lasting damage if missed
  • Cardiovascular disease. A higher risk of heart attack and stroke from chronic inflammation
  • Metabolic syndrome. Obesity, type 2 diabetes, high blood pressure, and high cholesterol
  • Mental health. Higher rates of depression and anxiety
  • Inflammatory bowel disease. An associated inflammatory condition of the gut
  • Fatty liver disease. Linked to the same metabolic inflammation

The burden

Why it matters to patients

Visible plaques, persistent itch, and pain affect sleep, work, relationships, and confidence, and the stigma of a visible disease adds a real emotional weight.

Care has expanded

There is more help than ever

Treatment has expanded well beyond topicals and phototherapy. Targeted therapies can now calm the specific immune signals that drive psoriasis, with treatment choices that require accurate diagnosis, severity assessment, and monitoring. Matching the right option, and screening for joint, heart, and metabolic disease, calls for specialty assessment.
