Psoriasis is a chronic skin condition that speeds up the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. These extra skin cells form scales and red patches that can be itchy and sometimes painful. While psoriasis can occur on any part of the body, it most commonly affects the elbows, knees, and scalp. People of any age can develop this condition, though it typically appears in early adulthood.
The symptoms of psoriasis vary from person to person but generally include red patches of skin covered with thick, silvery scales. These patches might be small or large and can sometimes merge to cover extensive areas. Other symptoms can include dry, cracked skin that may bleed, itching, burning sensations, thickened or ridged nails, and swollen, stiff joints. The severity of the condition can range from mild to severe, and it may worsen or improve unpredictably over time.
Treatment for psoriasis focuses on controlling symptoms and preventing infections. Common treatments include topical creams and ointments that reduce inflammation and slow down the rapid turnover of skin cells. Light therapy, where skin is exposed to natural or artificial ultraviolet light, can also be helpful. For more severe cases, oral or injected medications that affect the whole body might be prescribed by a healthcare provider. Making lifestyle changes such as maintaining a healthy diet, managing stress, and avoiding triggers can also help manage the condition effectively.
