What Causes Psoriasis?

Psoriasis is a chronic autoimmune condition that affects the skin, causing red, scaly patches to appear. But what exactly causes this condition to develop?


One of the primary factors that contribute to the development of psoriasis is genetics. Research has shown that individuals with a family history of psoriasis are more likely to develop the condition themselves. In fact, if one parent has psoriasis, the risk of their child developing it is around 10%. If both parents have psoriasis, the risk increases to 50%.

Immune System Dysfunction

Psoriasis is also closely linked to an abnormal immune response. In individuals with psoriasis, the immune system mistakenly attacks healthy skin cells, causing the rapid growth of new skin cells. This leads to the characteristic red, inflamed patches associated with the condition.

Environmental Triggers

While genetics and immune system dysfunction play a significant role in the development of psoriasis, environmental factors can also trigger flare-ups. Common triggers include stress, infections, certain medications, and even changes in weather. Identifying and avoiding these triggers can help manage the symptoms of psoriasis.

Lifestyle Factors

Additionally, lifestyle factors such as smoking, obesity, and excessive alcohol consumption have been linked to an increased risk of developing psoriasis. Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can help reduce the risk of developing psoriasis or alleviate symptoms in those already diagnosed with the condition.

By understanding the common causes of psoriasis, individuals can take proactive steps to manage their condition and improve their quality of life. While there is no cure for psoriasis, treatment options are available to help control symptoms and prevent flare-ups.
