Psoriasis

• Fact: About 1 in every 45 people will be diagnosed with the skin disease psoriasis, often by the age of 30.
• Proportion of risk that’s in your genes: 65 percent.
• What you can do:  If the results of your genetic test indicate you are at risk of psoriasis, be on the alert for symptoms. The earlier you identify symptoms of psoriasis and begin medical treatment, the better your chances of controlling psoriasis.
• Did you know? Psoriasis may be triggered by smoking, stress, heavy alcohol use and some medications.

Psoriasis is a common – and often uncomfortable – skin disease. In those who have it, white blood cells known as T cells go on the offensive, attacking healthy skin cells by mistake. The body then makes more skin cells, as well as more T cells, and as the battles between them ensue, skin cells pile up on the outermost layer of skin. They form thick, silvery scales and itchy red patches, which can bother psoriasis sufferers to no end.

About 6.6 million Americans have psoriasis, which often runs in families. Roughly one in three people with psoriasis has a close relative who also has it.

People who possess certain genetic variants have a greater chance of developing psoriasis. Yet while genetic factors are often behind the disease’s development, lifestyle also plays an influential role.

Knowing from genetic testing that you are genetically susceptible to psoriasis could encourage you to take positive steps for your health, possibly avoiding factors that may trigger the onset. Obesity, stress and smoking are all risk factors.

Understanding your genetic background can also help you work with your doctor on early detection. Sometimes psoriasis is an unsuspected cause of other health problems such as arthritis. Although no cure for psoriasis exists as yet, treatments can offer significant relief.
