What is PSORIASIS

 What i psoriasis

Psoriasis is a medical condition that occurs when skin cells grow too quickly. Faulty signals in the immune system cause new skin cells to form in days rather than weeks. The body does not shed these excess skin cells, so the cells pile up on the surface of the skin and lesions form. 

 





   signs and symptoms?

•  The lesions vary in appearance with the type of psoriasis. There are five types of psoriasis: 

         *Plaque, guttate, pustular, inverse, and erythrodermic. About 80% of   

           people living with psoriasis have plaque (plak) psoriasis, also called “  

           psoriasis vulgaris.”

• Plaque psoriasis causes patches of thick, scaly skin that may be white, silvery, or red. Called plaques (plax), these patches can develop anywhere on the skin. The most common areas to find plaques are the elbows, knees, lower back, and scalp. 

• Psoriasis also can affect the nails. About 50% of people who develop psoriasis see changes in their fingernails and/or toenails. If the nails begin to pull away from the nail bed or develop pitting, ridges, or a yellowish-orange color, this could be a sign of psoriatic arthritis.

What causes PSORIASIS

• Stress
• Sunlight
• Excessive alcohol consumption
• seasonal changes
• Hormonal changes

• because of certain drug withdraw with corticosteroid,lithium,choroquine.

Psoriasis is not contagious. You cannot get psoriasis from touching someone who has psoriasis, swimming in the same pool, or even intimate contact. Psoriasis is much more complex. 

Causing new skin cells to form in days rather than weeks. The reason T cells trigger this reaction seems to lie in our DNA. People who develop psoriasis inherit genes that cause psoriasis. Unlike some autoimmune conditions, it appears that many genes are involved in psoriasis.

Side Effected

When psoriasis flares, it can cause severe itching and pain. Sometimes the skin cracks and bleeds. When trying to sleep, cracking and bleeding skin can wake a person frequently and cause sleep deprivation.

A lack of sleep can make it difficult to focus at school or work. Sometimes a flare-up requires a visit to a dermatologist for additional treatment. Time must be taken from school or work to visit the doctor and get treatment.
