What is Psoriasis?

Psoriasis meaning can be understood with the knowledge of the layers of cellular tissues that forms the skin. The entire external surface of the body is covered by the skin, it is considered the largest organ of the body. The layers of cells that form skin from outside in are the epidermis, the outermost layer, the dermis which is the second layer just below the epidermis and the hypodermis which is the bottom fat layer providing the structural support. Psoriasis is a skin disease that affects the outer layer epidermis. Psoriasis disease is mainly due to the turning and growing too rapidly of the keratinocytes becoming scaly and these usually form on the lower portion of the epidermis layer. 

What is Psoriasis of the Skin?

Psoriasis definition-  Psoriasis disease can be defined as a non-contagious and long-lasting skin condition that constitutes because of the skin cells build-up that results in the formation of dry, itchy and scaly skin patches. It is an autoimmune disease. These are severe when spread through the entire body from scalp to navel area and toes and they can be localized patches affecting only some areas of the skin. Now that we are aware of the meaning of Psoriasis, let’s understand the reason for psoriasis.

What is the Main Cause of Psoriasis? 

The reason for Psoriasis and why Psoriasis occurs is still unknown and clear. It is understood that it is an autoimmune disease and due to an unknown reason for the condition of the immune system in the body there is inflammation caused to the skin. And due to this the new skin scales usually takes 10 to 30 days to form and develop the inflammation-causing it to form within 3 to 10 days. 

This rapid growth of skin when it is multiplying at a 10 times faster rate on top of one another appears scaly and the skin is dry and patchy. It is safe to say that Psoriasis is triggered by environmental factors along with a weak immune system. 

Psoriasis is also considered to be a genetic disease, it has been observed so through many pieces of research. And when there is a family history of Psoriasis disease the chances of getting it is very high. There have been some exceptions to this case as well that even when there is no family history of Psoriasis the next generation have a 10 per cent chance of being affected by it. In other cases, it has also been observed that Psoriasis can even skip a generation. 

It is observed that the T cells of the immune system start attacking the healthy skin cells in people with Psoriasis. And T cells that function by fighting invaders start harming the internal system itself that results in stimulation of white cells which causes more rapid new skin cells production. 

The Other Triggering Causes of Psoriasis Disease are:

  • The symptoms become more severe in cold temperatures.

  • When one smokes and consumes a lot of alcohol it leads to worsened symptoms of the disease.

  • A skin injury, such as a cut, bug bite, or even sunburn by spending a lot of time under the sun results in triggering the effects of Psoriasis. 

  • When one is affected with other diseases like HIV/AIDS that weakens the immune system the cells are no longer capable of resisting the effects of Psoriasis.

  • Excessive stress and tension can also hamper the healing process and increase the severity of symptoms. 

  • Allergies and diet are other triggers of Psoriasis.
