Psoriasis and other illnesses1

Psoriasis is a complex disease that can have effects, sometimes serious, on more than just the skin. The inflammation seen on the skin can also occur in other parts of the body, leading to conditions such as:

  • Psoriatic arthritis: affecting up to 35% of people with psoriasis.

  • Cardiovascular disease: strongly increased risk of angina, heart attack and blood clots.

  • Metabolic syndrome: increased risk of type 2 diabetes.

  • Obesity: 50% increased risk compared to the general population.

  • Inflammatory bowel disease: nearly 3 times increased risk of developing Crohn’s disease compared to the general population.

  • Depression: up to 60% of people with psoriasis also have depression.



Do you experience joint symptoms?

Joint symptoms can be a sign of psoriatic arthritis. If you experience joint symptoms discuss them with your doctor.

Record any symptoms you experience:

  • Tenderness, pain and swelling over tendons.

  • Swollen fingers and toes.

  • Stiffness, pain, throbbing, swelling and tenderness in one or more joints.

  • Reduced ability to move a joint.

  • Nail changes, e.g. the nail separates from the nail bed, becomes pitted or appears to  be infected with a fungus.


Steps you can take to stay healthy

  • See your GP for regular general health check-ups, including your emotional health.

  • Maintain a healthy weight by exercising regularly, eating a healthy diet and moderating your alcohol intake.

  • Don’t smoke, and if you do, speak to your doctor about how you could stop.

By treating your psoriasis and looking after your general health you can reduce your risk of developing conditions associated with psoriasis.
