Psoriasis Causes And Symptoms

June 20th, 2017

What is psoriasis?

Psoriasis is a non-communicable chronic skin disorder which manifests itself in the form of skin peeling and rashes. The disease can develop at any age, but most often psoriasis affects people of young age.

The intensity of psoriasis can vary widely at different stages. The disease can affect only minor areas of the skin or cover almost the entire body. Often the disease progresses, and patients note that over time (in the phase of intensification), psoriasis affects larger areas of the skin.

Different types of psoriasis manifest on different parts of a body. It usually emerges on the knees, elbows, and scalp, but can also affect the nails, torso, palms, and soles of the feet.

Causes and triggers of psoriasis

The development of this chronic skin disorder is triggered by:

  • Hereditary predisposition;
  • Chronic distress;
  • Hormonal disorders;
  • Viral infections;
  • HIV;
  • Excessive alcohol intake;
  • Smoking;
  • Skin injuries like a bad sunburn, insect bite, cut or scrape;
  • Obesity.

At the root of the appearance of psoriasis is the disruption of the immune system. Immune cells become aggressive towards their own skin cells, which leads to the appearance of psoriatic plaques.

Some medications could complicate the clinical course of a disorder. They include high blood pressure medications, lithium, some antimalarial drugs and Indomethacin.

Psoriasis Causes And Symptoms in Children

Pediatric psoriasis doesn’t differ much from adult and in 30% of cases is accompanied by itching. The Koebner phenomenon, which consists in the appearance of psoriatic eruptions in areas of trauma or skin irritation, is particularly prevalent in children. These rashes may be localized around injuries sustained from falling off a bicycle or even from too intense scratching. One-third of children with psoriasis suffer from nails abnormalities.

The main issues with pediatric psoriasis are severe psychological problems and risks of evolving into dangerous types (Pustular and Erythrodermic Psoriasis), that’s why it requires medical control.
The development of severe psoriasis in childhood does not mean that the person will continue to suffer from its severe form in the elder years. However, since psoriasis is a chronic disease, it is likely to persist for the whole life, periodically exacerbating and calming down.

There are 7 types of psoriasis:

  • Plaque Psoriasis;
  • Guttate Psoriasis;
  • Inverse Psoriasis;
  • Pustular Psoriasis;
  • Erythrodermic Psoriasis;
  • Nail Psoriasis;
  • Psoriatic Arthritis.

Pustular Psoriasis and Erythrodermic Psoriasis require immediate medical attention. Subjective feeling with this disorder might include fever, nausea, chills, severe itching and skin burning. Heart rate significantly increases and you might face muscle weakness.

Other types of psoriasis also should not be left self-directed. 10% to 30% of people with psoriasis develop psoriatic arthritis, and it’s essential to catch the earliest signs of this disease. Also, psoriasis causes cosmetical and psychological problems that sometimes lead to depressions and issues in communication with other people.
