What causes Psoriasis

Undstanding what is psoriasis you can learn how to manage this condition and live a better life.

Psoriasis is caused by a malfunction of the immune system.  Researchers have noticed that psoriasis can develop when something triggers the immune system.  T cells, a type of white blood cell, are at the root of the cause of psoriasis.  These T cells are attacking the skin where the psoriasis is located.  When doctors take a biopsy of psoriatic skin, they can see a lot of T cells underneath the plaque buildup.  The immune system in someone with psoriasis causes inflammation and rapid growth of skin cells, rather than protecting the body from foreign invaders as it is supposed to do.  Both genetics and environmental triggers seem to each play a role in the cause of psoriasis.

Psoriasis Treatment:
Psoriasis treatment is considered to be important in good management of the disease and of your overall health.  Patients can work with their doctors to decide on a course of treatment, or treatments. that can reduce or eliminate your symptoms.  Every person with psoriasis is different; what works for one psoriasis patient may not work for another.  It is important to keep trying all treatment options until you find the right one that works for you.


There are several types of treatment for moderate to severe psoriasis.  This involves a combination of topical ointments, phototherapy or systemic medications.  There are also treatments that are considered to be alternative, and these are not presently considered to be part of modern medicine.
