Causes and Risk Factors

Although the exact cause of psoriasis is yet to be found, researchers believe a combination of genetic, environmental, and immune factors may be involved.

Genetics

• The risk of getting psoriasis increases if a close biological relative has it.
• If one of your parents has psoriasis, you stand 10-25% chance of developing it.
• If both of your parents have it, your odds increase to 50%.

Obesity

• Researchers have suggested that psoriasis patients are more likely to be obese than the general population.
• Studies have shown that losing weight can help with symptoms of psoriasis and make treatments more effective.
