Psoriasis is characterized by skin cells that multiply up to 10 times faster than normal. As underlying cells reach the skin's surface and die, their sheer volume causes raised, red plaques covered with white scales. Psoriasis typically occurs on the knees, elbows, and scalp, and it can also affect the torso, palms, and soles of the feet.
The symptoms of psoriasis vary depending on the type you have. Some common symptoms include plaques of red skin, often covered with loose, silver-colored scales; these lesions may be itchy and painful, and they sometimes crack and bleed. In severe cases, the plaques of irritated skin will grow and merge into one another, covering large areas.
It can also cause disorders of the fingernails and toenails, including discoloration and pitting of the nails. The affected nails may also begin to crumble or detach from the nail bed. Some sufferers have plaques of scales or crust on the scalp.
Many factors ranging from emotional stress and trauma to streptococcal infection can cause an episode of psoriasis. Recent research indicates that some abnormality in the immune system is the key cause of psoriasis. As many as 80% of people having flare-ups report a recent emotional trauma, such as a new job or the death of a loved one. Most doctors believe such external stressors serve as triggers for an inherited defect in immune function.
Injured skin and certain drugs can aggravate psoriasis, including certain types of blood pressure medications (like beta-blockers), the anti-malarial medication hydroxychloroquine, and ibuprofen.
Psoriasis tends to run in families, but it may be skip generations; a grandfather and his grandson may be affected, but the child's mother never develops the disease. Although psoriasis may be stressful and embarrassing, most outbreaks are relatively harmless. With appropriate treatment, symptoms generally subside within a few months.
Choosing a natural product which is clinically proven and tested is a good start to manage psoriasis effectively.
