Psoriasis is a chronic autoimmune condition that primarily affects the skin, leading to the rapid growth of skin cells that accumulate, forming scales and red patches that can be itchy and sometimes painful. These changes occur due to an abnormal immune response that accelerates the skin renewal process. The disease can vary in severity, with some individuals experiencing mild flare-ups while others endure more severe symptoms. Psoriasis commonly appears on the elbows, knees, scalp, and lower back, but it can occur anywhere on the body.
There are several types of psoriasis, with plaque psoriasis being the most common form, characterized by raised, inflamed patches covered with silvery-white scales. Other types include guttate, inverse, pustular, and erythrodermic psoriasis. While the exact cause of psoriasis is still not entirely understood, it is believed to involve genetic, environmental, and immune system factors. Treatments vary widely and can range from topical medications and phototherapy to systemic treatments aimed at reducing inflammation and slowing skin cell turnover. If you suspect you have psoriasis, consulting a healthcare provider is advisable to explore the most appropriate treatment options.
