Psoriasis

What is psoriasis?

Psoriasis is an autoimmune disease that causes red, scaly, inflamed patches of skin. These patches can develop anywhere on the body but are most common on the scalp, face, knees, elbows, and the trunk of the body. Identifying your triggers is essential to minimize your number of psoriasis flare-ups.

What are the different types of psoriasis?

The most common types of psoriasis are:

Plaque psoriasis

Plaque psoriasis, the most common type, causes red, raised patches of scaly skin to develop on the scalp, knees, back, and elbows. These lesions may be itchy and raw from scratching.

Guttate psoriasis

Guttate psoriasis is common in children and often results from a bacterial infection. If your child has guttate psoriasis, their lesions may appear teardrop-shaped. 

Nail psoriasis

Nail psoriasis causes the nails to appear curved, pitted, or separated from the nail bed. Nail discoloration and distortion are also common signs of nail psoriasis.

Psoriatic arthritis

Many people with psoriasis also develop a painful form of joint inflammation called psoriatic arthritis. Along with red, inflamed skin, psoriatic arthritis causes swollen, stiff joints.

What causes psoriasis?

Psoriasis is an overreaction from the immune system in which the skin regenerates too quickly, causing a buildup of red, scaly patches on the skin. If you already have psoriasis, certain factors can trigger flare-ups. Common psoriasis triggers include:

• Cold, dry weather
• Stress
• Smoking cigarettes
• High blood pressure medications and antimalarial drugs
• Skin injuries
• Insect bites
• Burns
• Skin infections
• Strep throat and other viral or bacterial infections

You’re more likely to develop psoriasis if a close relative, like a parent or sibling, already has the autoimmune disease. 

What are the treatments for psoriasis?

Dr. Robare and the team choose the right psoriasis treatment for you based on the type and severity of your condition. Trigger identification and avoidance are key factors in minimizing flare-ups. Other possible treatments for psoriasis include:

• Topical corticosteroids
• Retinoids
• Salicylic acid
• Light therapy
• Injectable and oral treatments

To minimize itching at home, Dr. Robare may recommend applying soothing ointments, like aloe extract. Scratching psoriasis lesions can irritate your skin and cause additional injury, so it’s important to avoid aggravating your plaques.
