Anyone can develop psoriasis. About a third of instances begin in childhood. These factors can increase the risk of developing the disease:
• 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.
• Smoking: Smoking tobacco not only increases the risk of psoriasis but also may increase the severity 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
• Temporary skin color changes (post-inflammatory hypopigmentation or hyperpigmentation) where plaques have healed
• 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
