Psoriasis: Symptoms, Triggers and How to Manage Flare-Ups

Psoriasis is a chronic, immune-related skin condition that speeds up the life cycle of skin cells, causing them to build up into thick, scaly patches. It affects millions of people and, while it can't be cured, it can be very effectively controlled with the right care.

Common Symptoms

• Thick, red or pink patches covered with silvery-white scales.
• Dry, cracked skin that may itch, burn or bleed.
• Patches commonly on the scalp, elbows, knees and lower back.
• Nail changes such as pitting, thickening or discolouration.

What Triggers Psoriasis Flare-Ups?

• Stress and lack of sleep.
• Infections, such as a throat infection.
• Cold, dry weather.
• Skin injury, cuts or sunburn.
• Smoking and excess alcohol.
• Certain medications.

Is Psoriasis Contagious?

No. Psoriasis is not contagious — you cannot catch it from or pass it to another person. It is driven by an overactive immune system, often with a genetic component.

How Psoriasis Is Managed

Treatment depends on severity and may include medicated topical creams, phototherapy (controlled UV light) and, for moderate-to-severe disease, systemic or biologic medication. Alongside this, identifying and reducing your personal triggers, moisturising well and managing stress make a big difference to how often flares occur.
