Psoriasis is a chronic skin condition characterized by patches of red, inflamed skin covered with white or silvery scales. These patches can appear anywhere on the body but are commonly found on the elbows, knees, and scalp. Psoriasis is not contagious and cannot be spread through physical contact.
Psoriasis occurs when the life cycle of skin cells speeds up. Skin cells grow, die, and fall off in a month. However, in the case of psoriasis, this process is expedited, taking just a few days. This rapid turnover of skin cells results in the build-up of scales and red patches. The condition is linked to an overactive immune system, although its exact cause remains unclear.
There are different types of psoriasis, with plaque psoriasis being the most common. Other forms include guttate psoriasis, inverse psoriasis, pustular psoriasis, and erythrodermic psoriasis. Each type has its own symptoms, but they all share the common feature of abnormal skin patches.
Although there is no cure for psoriasis, treatments are available to manage its symptoms. Topical creams, light therapy, and medications are commonly used to reduce inflammation and skin cell turnover. Lifestyle changes like stress management, a balanced diet, and regular exercise can also help manage the symptoms.
Several factors can trigger or worsen psoriasis. These include stress, infections, injuries to the skin, and certain medications. Alcohol and tobacco use have also been linked to the severity of psoriasis symptoms. Therefore, avoiding these triggers may help control flare-ups.
While psoriasis can be long-term, many people find relief through treatment and lifestyle changes. Consulting a dermatologist for an accurate diagnosis and appropriate treatment plan is essential.
