Psoriasis Signs and Symptoms – Health

Psoriasis is a disease that kicks skin-cell production into overdrive. New cells surface in a matter of days, instead of weeks, piling up faster than theyre shed. With plaque psoriasis, the most common type of this skin condition, rapid skin-cell renewal creates scaly, raised patches, called plaques, on the skins surface.

Psoriasis is an autoimmune disease, meaning the bodys own immune system is somehow tricked into attacking healthy cells. In the case of psoriasis, this process causes the skin to become scaly and inflamed.

Why does this happen? Its clear that the genes you inherit play a role, since psoriasis tends to run in families. But even if you have a genetic predisposition, it doesnt mean you will develop the skin condition. Scientists think something in your environmentbe it stress, injury, infection, medication, or weather (particularly extremely cold or dry air)must trigger or worsen symptoms.
