Psoriasis - an overview
Psoriasis is a common skin disease affecting 1 in 50 people. It occurs equally in men and women. It can appear at any age. Psoriasis is a long-term condition which may come and go throughout your lifetime. It is not infectious; therefore you cannot catch psoriasis from someone else. It does not scar the skin although sometimes it can cause a temporary increase or reduction in skin colour. Although psoriasis is a long-term condition there are many effective treatments available to keep it under good control.
Psoriasis can affect the nails and the joints as well as the skin. Psoriatic arthritis produces swelling and stiffness in the joints or stiffness in the lower back and should be managed by a rheumatologist who works closely with your dermatologist and/or your GP.
Psoriasis, particularly moderate to severe psoriasis, is associated with an increased risk of anxiety, depression and harmful use of alcohol. Moderate to severe psoriasis increases the risk of heart disease and stroke and treatment of psoriasis may reduce this risk. Psoriasis can also be associated with diabetes, obesity, venous thromboembolism, high cholesterol and high blood pressure. Psoriasis is also associated with inflammatory bowel disease and there is a small increased risk of skin cancer.
