Psoriasis

Psoriasis is caused by an overactive immune system that accelerates skin cell production, leading to the buildup of thick, scaly patches. It is often influenced by genetic factors and environmental triggers.

Risk factors for psoriasis include a family history of the condition, stress, obesity, infections, smoking, and certain medications, which can all exacerbate symptoms or trigger flare-ups.

Symptoms of psoriasis commonly include red patches of skin covered with silvery scales, which can cause itching, burning, or soreness. These plaques often appear on the scalp, elbows, knees, and lower back.

Psoriasis describes a group of skin conditions that include:

• Plaque psoriasis, which is most common and manifests as red patches covered in silvery scales
• Guttate, which shows up as dot-like pimples on the body
• Inverse psoriasis that appears as bright red lesions in folds, such as under the arm, or in the groin
• Pustular psoriasis, consisting of white blisters of pus surrounded by red skin
• Erythrodermic, which is an exceptionally severe form that causes bright redness over the whole body, resulting in severe itching and pain

The providers at Raleigh Dermatology do a thorough physical exam, review your symptoms, and discuss with you your medical and family history to determine if you have psoriasis. No blood test can diagnose it, but they may order a skin biopsy to see if the psoriatic skin is thicker and inflamed.

Psoriatic arthritis is a form of arthritis that can affect some people with psoriasis. It causes pain and swelling in the joints. If you have these problems, mention them to your doctor or nurse.

People with psoriatic arthritis can take medicines to reduce pain and swelling. Exercise and physical therapy can also help. Plus, some of the same medicines that help with the skin problems caused by psoriasis also help with psoriatic arthritis.
