Psoriasis is a long-term immune condition that makes skin cells build up too quickly. It causes thick, red or dark patches with silvery scales, often on the elbows, knees, scalp and lower back. It is not contagious.
Possible triggers
- Stress
- Infections, such as a sore throat
- Skin injury, including scratches and tattoos
- Smoking and alcohol
- Some medicines; tell your doctor about everything you take
- Sudden stopping of steroid tablets
Living with psoriasis
- Moisturise daily to reduce scaling and itch
- Take short, lukewarm baths
- Use medicines regularly as prescribed, even when skin looks better
- Small amounts of sensible sunlight may help some people; ask your doctor first
- Look after your overall health; psoriasis is linked to joint pain, weight and heart health
Treatment
Treatment depends on how much skin is affected and may include creams, scalp treatments, phototherapy and tablets or injections for more severe disease. A dermatologist will tailor treatment and monitor you.
