Psoriasis

Overview

Psoriasis is a chronic, recurrent, inflammatory skin disease typically presenting as well-demarcated red plaques covered with silvery-white scales. Lesions may be itchy and range from small patches to widespread involvement, and skin injury can trigger new lesions (Koebner phenomenon). Patients have a higher risk of psoriatic arthritis, cardiovascular disease, and depression, and it is considered a genetically influenced condition triggered by environmental factors.

Symptoms

• Erythema
• Scaling
• Itching
• Plaques
• Cracking

Treatment

Treatment is based on topical medication and skin moisturization, with phototherapy or systemic therapy for moderate to severe cases, requiring long-term standardized dermatology care.

Dietary advice

Eat a light, balanced diet, quit smoking, limit alcohol, control weight, and eat plenty of fresh fruits and vegetables.
