Psoriasis

Psoriasis is a long-lasting skin condition that causes red, scaly patches and can impact daily life. Learn about symptoms, possible triggers and treatment options to help manage and improve your quality of life.

Psoriasis is a common, long-term skin condition caused by an overactive immune response. It leads to red, inflamed patches of skin often covered with silvery white scales. Genetics and immune system factors cause skin cells to grow and shed faster than normal. Psoriasis can range from mild to widespread and may affect daily life and overall well-being.

Types of Psoriasis

  • Plaque psoriasis is the most common form, marked by raised, scaly patches.
  • Guttate psoriasis appears as small, drop-like spots.
  • Inverse psoriasis affects skin folds.
  • Pustular psoriasis causes white pustules surrounded by red skin.
  • Erythrodermic psoriasis is a severe form with widespread redness.

Symptoms to Look For

  • Red or pink plaques with thick, silvery scale
  • Itching or burning
  • Cracked or bleeding skin
  • Nail changes such as pitting, thickening or separation
  • Joint pain or swelling, which may signal psoriatic arthritis
  • Symptoms often come and go, and certain triggers may cause flares.

What Causes Psoriasis?
Psoriasis develops from a combination of genetic risk and immune system changes. Triggers may include infections such as strep throat, skin injuries, certain medications, stress, smoking, heavy alcohol use and hormonal changes. Obesity and metabolic conditions may also worsen symptoms.

Risk Factors

  • Family history of psoriasis
  • Other autoimmune conditions
  • Obesity
  • Smoking or excessive alcohol use
  • History of certain infections

Psoriasis can begin at any age but often starts in early adulthood or between ages 50 and 60.

How Psoriasis is Diagnosed
Diagnosis is usually based on a review of your health history and an exam of the skin, scalp and nails. In some cases, a skin sample may be taken to rule out other conditions. If joint symptoms are present, further evaluation for psoriatic arthritis may be recommended.
