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.
