What causes Psoriasis?
While the exact causes of psoriasis are not yet fully understood, two factors appear to play a key role: dysfunction in the immune system and genetic predispositions.
By understanding these internal causes of psoriasis, we hope that you can see your condition in a new light. Despite its overactive response, your body is ultimately trying to protect you.
Psoriasis starts beneath the surface. It is an autoimmune disease, meaning it is caused by an overactive immune response to an external or internal trigger. The overstimulated immune system attacks the body’s own skin cells, causing the body to make new skin cells more often, and resulting in the visible symptoms you see on the surface.
While the role of environmental triggers is well understood, it is also believed that more than 60 gene variants contribute to a person’s likelihood of developing psoriasis. However, the link is complicated. There isn’t a “psoriasis gene.” In fact, in 60% of people living with psoriasis, no other family member has previously been affected by the condition.
Certain triggers associated with psoriasis can make flare-ups more frequent and severe. Triggers may include:
Many of these triggers can be reduced by adopting a healthy lifestyle.
