Psoriatic disease is a systemic condition, meaning that the inflammation associated with it also has the potential to affect other parts of the body. When this occurs, it is called a comorbidity.
Other diseases that are more likely to occur simultaneously with psoriasis include rheumatoid arthritis, inflammatory bowel disease, diabetes, obesity and heart disease.1 Having psoriasis does not mean that you will experience these other conditions, just that you are at a somewhat increased risk of doing so.
