Everything You Need To Know About Psoriasis

Psoriasis is an autoimmune condition that causes the rapid growth of skin cells. This fast skin growth results in the scaling of the skin. Psoriatic scales are thick and red patches with inflammation around the borders. If touched, these scales crack and bleed. 

The life cycle of a typical skin cell is one month. In psoriasis, the scale develops from deeper skin cells and rises to the skin surface. Ultimately, the scale falls off. But in people who have psoriasis, this cycle speeds up, and cells do not have time to fall off. Instead, they accumulate and form scales on the skin’s surface.

What Are The Specific Sites Of Psoriasis?

Psoriatic scales develop mainly on joints, including knees and elbow joints. Other sites include:

  • Face
  • Neck
  • Hands
  • Feet
  • Scalp

What Are The Different Types Of Psoriasis?

  • Plaque psoriasis:

Plaque psoriasis is the most common type of psoriatic scale that develop as red and inflamed patches over the skin. The prevalence of these types of scales is 80-90%. The scales are covered with whitish-silver scales. The most common sites of these scales are the scalp, elbows, and knees.

  • Pustular psoriasis:

Pustular psoriasis presents with pus-filled scales or blisters and is more common in adulthood. The most common location of these scales is the small body areas, such as the hands and feet.

  • Guttate psoriasis:

Gutatte psoriasis is more common in childhood. It presents as small lesions that are pink or violet in color. The most common locations of these scales include the arms, legs, and torso. Gutatte psoriasis does not present as raised lesions like the one in plaque psoriasis.

  • Inverse psoriasis:

Inverse psoriasis presents as red, shiny, and inflamed lesions. These scales or lesions are commonly found in the armpits, groin region, under the breasts, and around the genitals.

What Are The Causes Of Psoriasis?

Doctors do not have an obvious explanation of the causes of psoriasis. But a great deal of research has put forward two leading causes of psoriasis: genetics and the immune system.

  • Immune system:

Our immune system employs white blood cells to attack and destroy bacteria and other foreign agents—autoimmune conditions such as psoriasis result when the immune system works against the body’s cells. In the case of psoriasis, white blood cells called T cells, attack your skin cells. This results in your skin cells go into overdrive and multiplying a great deal which ultimately results in the piling up of skin cells forming plaques or scales.

  • Genetics:

Studies suggest that if you have an immediate family member that is suffering from this skin condition, then it is highly likely that you are at risk of developing the disease. This is because you may have inherited genes that make an individual more vulnerable to developing this condition.
