How Do You Get Psoriasis?
Around the world, one to three percent of the total population is affected by psoriasis. While not deadly, this uncomfortable dermatological disorder causes its victims occasional flare-ups of red patches covered with flakes. While the condition is normally confined to the scalp, it is known to appear anywhere on the body, and there are many causes of psoriasis.
The primary cause of this debilitating disorder is due to abnormalities in the immune system with a root cause being the accumulation of white blood cells known as T cells. When these cells proliferate in the area where the psoriasis is located, they begin to attack that area of the skin.
While studying the accumulations of T cells, scientists made a discovery regarding what causes psoriasis outbreaks. Large populations of T cells were observed in these areas; rather than protecting the body from outside invaders, they instead cause the skin to grow at a rapid rate.
When analyzing what causes psoriasis, there are other factors to consider. For example, the type of psoriasis is key since there are various forms with unique characteristics. What causes scalp psoriasis varies compared to inverse psoriasis causes. Those suffering from scalp psoriasis has a higher chance of an outbreak during times of stress or weather change while inverse psoriasis victims need to beware of obesity and injuries to the skin.
Psoriasis is a broad term which refers to a plethora of specific forms, however they all share common characteristics. All forms of psoriasis are due to abnormalities in the T cells. In determining what are the causes of psoriasis, studies have shown that in 66 percent of cases, a family history of the disease existed. This strongly suggests that genetics plays a significant role in determining who may be at risk.
Many psoriasis sufferers notice a time of the year when their condition seems to clear up only to return at a later time. Commonly, wintery conditions cause these flare-ups as the drier air helps foster development. There are also certain medications such as Lithium used for high blood pressure that are prone to triggering outbreaks. Other causes include infections and high-stress situations.
