Psoriasis in Canada: Symptoms, Treatment, and What to Expect

Psoriasis is a chronic autoimmune condition that causes skin cells to multiply up to 10 times faster than normal. This creates thick, scaly patches that can be uncomfortable and affect quality of life. Approximately 1 million Canadians live with psoriasis. The most common type - plaque psoriasis - appears as raised, red patches covered with silvery-white scales, typically on the scalp, elbows, knees, and lower back. Other types include guttate, inverse, pustular, and erythrodermic psoriasis. Psoriasis is not contagious. It is driven by an overactive immune system, and both genetic and environmental factors play a role. Common triggers include stress, skin injuries, infections, certain medications, and cold, dry weather. Treatment options depend on severity. Mild psoriasis may respond to topical corticosteroids and moisturizers. Moderate to severe psoriasis may require phototherapy (controlled UV light treatment), systemic medications (e.g., methotrexate, cyclosporine), or biologic therapies targeting specific immune pathways. The financial burden of psoriasis treatment in Canada can be significant, especially for biologics. Provincial drug programs and manufacturer assistance programs may help offset costs. Private insurance coverage varies. A physician can assess psoriasis symptoms and initiate treatment, even through telehealth for initial evaluation. *This article is for informational purposes only.*
