Everything You Should Know About Psoriasis

What is Psoriasis?

Psoriasis is a skin disease that makes the skin cells abnormally multiply ten times faster than normal.  It causes a rash with itchy, scaly patches, most commonly on the knees, elbows, trunk and scalp.

What are the symptoms?

The symptoms vary based on the type of psoriasis you have. Some common symptoms of plaque psoriasis (the most common variety of the condition) are:

  • Raised patches of skin that appear red, brown, or purple
  • Whitish-silver scales or plaques on the red patches or grey scales on purple and brown patches
  • Dry skin associated with cracking and bleeding
  • Soreness around patches
  • Itching and burning sensation
  • Thick, pitted nails
  • Painful, swollen joints

What causes psoriasis?

The two factors that are believed to cause psoriasis are:

  • The immune system: It is an autoimmune condition. Autoimmune conditions are the result of your body attacking itself (self-attack).
  • Genetics: Some people inherit genes that make them more prone to develop psoriasis.

What are the risk factors for psoriasis?

Common psoriasis risk factors include:

  • An injury to your skin
  • Excessive intake of alcohol
  • Smoking
  • Stress
  • Hormonal changes
  • Certain medications
  • Immune diseases (HIV)

What is the diagnosis for psoriasis?

To diagnose psoriasis, your dermatologist will examine your skin, nails, and scalp for signs of psoriasis. The dermatologist will also ask if you have any: 

  • Symptoms like itchy skin
  • Joint problems (pain and swelling or stiffness when you wake up)
  • Blood relatives who have psoriasis
  • Stress

Biopsy:

If your symptoms are not clear, or your dermatologist wants to confirm the diagnosis, they will take a small sample of your skin; this procedure is called a biopsy.

It is then sent to a lab for analysis. This biopsy examination can diagnose the type of psoriasis you have. 

What is the treatment for psoriasis?

The primary aim of psoriasis treatment is to stop the abnormal multiplication of skin cells and the removal of scales.

The treatment options include:

  • Creams and ointments
  • Light therapy (phototherapy)
  • Oral or injected medications

How to prevent psoriasis?

The best way to prevent or reduce the risk of spreading psoriasis is to avoid the triggers. 

Check out some of the things you can do to prevent or reduce the risk of psoriasis flare-ups:

  • Reduce your stress
  • Avoid certain medications
