Remember our surprising stats on just how many people suffer from Psoriasis in the US? Well, we caught up with Dr. J. Mark Jackson, board certified dermatologist, to pick his expert brain on this skin condition.

Check out the doctor's answers to our basic questions on the symptoms and how to treat psoriasis below:

What triggers psoriasis? Is it hereditary? Based on diet, lifestyle?

Psoriasis is a chronic, autoimmune inflammatory disease that appears on the skin, occurring when the immune system sends out signals that speed up the growth cycle of skin cells.

Triggers for psoriasis vary from person to person and not all triggers have been fully identified, but they can include stress, skin injury (including scratching, bug bites, scrapes and bruises or burns) and medications.

How does psoriasis trigger or lead to other diseases?

As many as 30% of people with psoriasis will eventually develop psoriatic arthritis. Patients may experience skin symptoms for 10+ years before the onset of joint symptoms.

Additionally, psoriasis may also elevate the risk of a handful of other serious health conditions including cardiovascular disease, metabolic syndrome, cancer and other immune-mediated inflammatory diseases such as Crohn's disease and multiple sclerosis.
