What Causes Psoriasis?
Psoriasis is a chronic (recurring and long lasting) skin disease that affects about 1 to 2% of the general population. It is not contagious. This skin disease is evidenced by thick, itchy, red, raised skin areas that are covered with silvery white scales that commonly affect areas such as the scalp, knees, elbows, lower back although any area of the body can be affected by psoriasis.
If you are wondering what causes psoriasis, there is currently no single identified cause although many researchers believe that certain factors such as the genes, the immune system, the environment and skin cells may play a part in the advent of psoriasis.
While genes play an important role, one will not necessarily get this disease if they have a family history of the condition and another will not avoid the condition simply because there is no family history of the condition. Understanding why psoriasis develops in a particular individual is very complicated and there are no easy or clear cut answers.
It is however accepted that the immune system is critical to the development of psoriasis. Psoriatic skin regenerates skin in three to four days which is extremely faster than the normal skin regeneration period which occurs on average after twenty eight to thirty days. The overactive skin regeneration associated with psoriasis leads to the raised skin patches or plaques.
It is greatly believed that this increased skin regeneration process is the result of “faulty wiring” in the immune system which causes abnormal reactions in the skin.
Though psoriasis can develop at any age, it is commonly diagnosed is men and women between the ages of 15 and 35. And while this condition can affect anyone of any racial background, it seems to affect less people of Native American, Japanese, Inuit, West African and African American backgrounds which leads to the conclusion that environmental factors may play an important role in the development or avoidance of psoriasis.
Psoriasis Flare-Up Triggers
Psoriasis symptoms can be triggered by various factors such as infection, the climate, some medications, injury to the skin as well as stress. When trying to control these flare-ups, it is important to recognize the particular triggers and try to control them as a way to manage psoriasis in addition to using various drugs as well as home remedies for psoriasis.
Know The Symptoms of Psoriasis
Knowing the symptoms of psoriasis will help in finding treatment as well as knowing what the trigger as that led to the development of a particular symptom. The symptoms of psoriasis vary depending on the type and severity of the psoriasis and the appearance of psoriasis can vary from one sufferer to another which also means that various treatments such as home remedies for psoriasis will affect sufferers differently.
Psoriasis usually appears as dry, red, raised, scaly patches of skin. About 15 to 30% of psoriasis sufferers also suffer from arthritis causing what is known as psoriatic arthritis evidenced by swollen, tender and stiff joints. Psoriasis can also affect the nails and cause crumbling of the nail bed as well as deformity with the nails.
There are many drug therapies to deal with the symptoms of psoriasis and many such as home remedies for psoriasis will usually involve a lot of trial and error because what will work for one sufferer may not necessarily work for another. Even though psoriasis can affect only small areas, its impact on a sufferer can still be great since we live in an image obsessed world and every slight imperfection can lead to ridicule or the loss of self esteem. The skin is the largest organ of the body and is visible to other people and suffering from psoriasis can be very burdensome.
