If you have psoriasis, you're at greater risk of developing certain diseases. These include:
- Psoriatic arthritis. This complication of psoriasis can cause joint damage and a loss of function in some joints, which can be debilitating.
- Eye conditions. Certain eye disorders — such as conjunctivitis, blepharitis and uveitis — are more common in people with psoriasis.
- Obesity. People with psoriasis, especially those with more severe disease, are more likely to be obese. It's not clear how these diseases are linked, however. The inflammation linked to obesity may play a role in the development of psoriasis. Or it may be that people with psoriasis are more likely to gain weight, possibly because they're less active because of their psoriasis.
- Type 2 diabetes. The risk of type 2 diabetes is upped in people with psoriasis. The more severe the psoriasis, the greater the likelihood of type 2 diabetes.
- High blood pressure. The odds of having high blood pressure are higher for people with psoriasis.
- Cardiovascular disease. For people with psoriasis, the risk of heart attack is almost three times greater than for those without the disease. The risk of irregular heartbeats and stroke is also higher in those with psoriasis. This could be due to excess inflammation or to an increased risk of obesity and other risk factors for cardiovascular disease. Some psoriasis treatments may cause abnormal cholesterol levels and increase the risk of hardened arteries.
- Metabolic syndrome. This is a cluster of conditions — including high blood pressure, elevated insulin levels and abnormal cholesterol levels — that increases your risk of heart disease. People with psoriasis have a higher risk of metabolic syndrome.
- Other autoimmune diseases. Celiac disease, sclerosis and the inflammatory bowel disease called Crohn's disease are more likely to strike people with psoriasis.
- Parkinson's disease. This chronic neurological condition is more likely to occur in people with psoriasis.
- Kidney disease. Moderate to severe psoriasis has been linked to a higher risk of kidney disease.
