What are the Causes of Psoriasis?

While the exact cause of psoriasis is still unknown, medical science holds these factors responsible for the disease.

Psoriasis is an autoimmune disease caused by the rapid growth of the skin cells. Consequently, the skin is teemed with the dead cells on the surface. They look like raised and dry patches. It is usually found on the knees, elbows, and scalp, though it occurs on the legs, nails and trunk.

So what are the triggers leading to psoriasis? Or what cause psoriasis?

Well, the exact cause of psoriasis isn’t still understood. However, medical science believes that psoriasis is due to the combination of factors like genetics, environmental factors and the immune system. Psoriasis is found in the members of the same family. Or defects in immune system (when it mistakenly kills healthy cells instead of foreign bodies) can play a major role. Inflammation can be a reason sometimes. However, the exact cause of psoriasis is still a mystery.

Here we have discussed the possible causes (according to researches so far) of psoriasis.

Hereditary:

If you have psoriasis, someone may be in your family may have had it too. It means that it can be genetic. 20% people with psoriasis reported that they have a relating with the same disease. According to some researches, 10% of general population may carry one or more genes that lead them to psoriasis, though only 2%-3% of people with gene are actually prone to the disease.

Injuries to the Skin:

Sometimes cuts, scrapes, bug bits, wearing poorly fitted shoes and sunburns can cause enough skin irritation or injury to trigger psoriasis, also known as Koebner phenomenon. It occurs as neat and linear plaques that rise directly from the site of previous scrape or cut. Top of that, scientists don’t know what causes Koebner’s phenomenon. Some research suggests that it may be due to changes in the blood capillaries delivering to the skin, which somehow prompt inflammation. It is likely to occur more in winter; and people with high flare up rate are more prone to it.

Defects in the Immune System:

The immune system protects when foreign particles like virus enters the body. But sometimes the immune system mistakenly kills the health cells by taking them as intruders. People with psoriasis have an overactive immune system. It leads to inflammation inside the body, which creates the signs occurring on the skin. This way, it boosts the production of the cells that occur as the raised skin on the surface. Generally, it takes about a month for your skin cells to go across the body. But with psoriasis, it just takes days. The body is not able to shed skin cells that quickly, therefore the cells continue to build on the surface of the skin.

Viral and Bacterial Infections:

People with HIV are more prone to psoriasis than people with healthy immune systems. Kids and older adults with recurring infections like strep throat are also at risk.

Stress:

Stress prompts immune systems to release inflammation that add to a psoriasis flare. A recent study by National Psoriasis Foundation linked psoriasis to stress related disorders.

So these are the causes of psoriasis as suggested by the researches so far. Keep in mind that psoriasis is not curable. However, the symptoms are controlled with medications. If you are suspect of psoriasis, contact your doctor to get the treatment on time. You are also required some lifestyle changes given below:

• Minimizing Stress
• Wear sunscreen and clothes to protect the skin from the sun.
• Practice Good Hygiene
• Take a healthy diet as obesity can turn your psoriasis worse.
• Use topical treatments like to control the itch and inflammation.
