Psoriasis is a chronic autoimmune skin condition that affects millions of people worldwide. It occurs when the immune system mistakenly speeds up the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. This results in thick, scaly patches that can be uncomfortable, itchy, and sometimes painful. Although psoriasis is not contagious, it is a long-term condition that often comes and goes in cycles.
The exact cause of psoriasis is not fully understood, but it is believed to be linked to immune system dysfunction and genetics. People with a family history of psoriasis are more likely to develop the condition. Certain triggers can cause symptoms to appear or worsen, including stress, infections, skin injuries, cold weather, smoking, and excessive alcohol consumption.
Symptoms of psoriasis vary from person to person. The most common signs include red patches of skin covered with silvery-white scales, dry or cracked skin that may bleed, itching or burning sensations, and thickened or ridged nails. In some cases, psoriasis is associated with psoriatic arthritis, which causes joint pain, stiffness, and swelling.
