Psoriasis is a chronic autoimmune condition that affects the skin. The exact cause of psoriasis is not fully understood, but it is thought to be a combination of genetic and environmental factors.
In psoriasis, the immune system mistakenly attacks healthy skin cells, causing them to grow too quickly and build up on the surface of the skin. This leads to the formation of thick, scaly patches or plaques on the skin that can be red, itchy, and painful.
Research has shown that certain genes are associated with psoriasis, and that environmental triggers such as stress, infections, injuries, and certain medications can also play a role in triggering or worsening psoriasis symptoms. Additionally, the immune system dysfunction that occurs in psoriasis is believed to involve the overproduction of inflammatory molecules known as cytokines.
Overall, psoriasis is a complex condition with multiple factors contributing to its development and progression. While there is no cure for psoriasis, there are effective treatments available to help manage symptoms and improve quality of life for those affected by the condition.
