Psoriasis: Types, Symptoms & Triggers
Psoriasis is a chronic skin disease causing red, itchy patches with white, silvery scales depending on the severity. This autoimmune condition, usually hereditary, puts a certain type of white blood cells known as leucocytes on high function mode making it over develop skin cells up to ten times. These skin cells surface to the top level much faster than the normal skin development cycle works and hence, expose the lesions causing itching and irritation.
There are different types of psoriasis: plaque, guttate, pustular, erythrodermic, inverse, scalp, nails and psoriatic arthritis that may affect different parts of the body. In order to have a proper treatment, it is very important to know the type of psoriasis one is suffering from.
Psoriasis is often triggered by physical and psychological exhaustion, leading to stress situations for the body and mind. An erratic lifestyle, high-pressure work situations, personal life issues could act as a trigger if the individual continues to be stressed over a prolonged period.
During winter, when the skin is most likely to dry up faster, in general, psoriatic patients have a harder time dealing with the condition due to constantly drying skin. Living in or visiting places with low or no humidity can cause flare-ups as the skin does not receive any moisture from the air and in turn dries much faster.
