Anyone can develop psoriasis. About a third of instances begin in the pediatric years. These factors can increase your risk:
• Family history: The condition runs in families. Having one parent with psoriasis increases your risk of getting the disease, and having two parents with psoriasis increases your risk even more.
• Stress: Because stress can impact your immune system, high stress levels may increase your risk of psoriasis.
• 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.
If you have psoriasis, you're at greater risk of developing other conditions, including:
• Psoriatic arthritis, which causes pain, stiffness and swelling in and around the joints
• Eye conditions, such as conjunctivitis, blepharitis and uveitis
• Type 2 diabetes
• High blood pressure
• Cardiovascular disease
• Other autoimmune diseases, such as celiac disease, sclerosis and the inflammatory bowel disease called Crohn's disease
• Mental health conditions, such as low self-esteem and depression
