Anyone can develop psoriasis, but these factors can increase your risk of developing the disease:
Apr. 11, 2014
- Family history. Perhaps the most significant risk factor for psoriasis is having a family history of the disease. Having one parent with psoriasis increases your risk of getting the disease, and having two parents with psoriasis increases your risk even more.
- Viral and bacterial infections. People with HIV are more likely to develop psoriasis than people with healthy immune systems are. Children and young adults with recurring infections, particularly strep throat, also may be at increased risk.
- Stress. Because stress can impact your immune system, high stress levels may increase your risk of psoriasis.
- Obesity. Excess weight increases the risk of psoriasis. Plaques associated with all types of psoriasis often develop in skin creases and folds.
- Smoking. Smoking tobacco not only increases your risk of psoriasis but also may increase the severity of the disease. Smoking may also play a role in the initial development of the disease.
