Psoriasis is a skin disease characterised by grey or silvery flaky patches on the skin which are red and inflamed when scratched.
What causes psoriasis? Psoriasis is the growth of too many skin cells - eight times more than the average. The first outbreak is often triggered by stress.
What triggers psoriasis? Triggers include streptococcal infection, sun exposure, alcohol, drug reactions, hormonal factors and psychological factors.
What are the psoriasis risk factors? The disease is genetic and the most significant risk factor is a family history of the condition.
What is the topical treatment for psoriasis? Some patients respond well to ointment or cream forms of corticosteroids, vitamin D3, retinoids, coal tar or anthralin. The medication that is best may depend on the type and location of the psoriasis.
What is the phototherapy treatment? Phototherapy treatment uses ultraviolet (UV) light to kill T cells in skin, reducing redness and slowing the overproduction of skin cells that causes scaling.
What is the systemic treatment for psoriasis? This involves taking medicines internally by pill or injection. Systemic psoriasis treatment drugs include methotrexate, retinoids, cyclosporine.
