What is Psoriasis? Causes, Symptoms, Treatment, and More


Psoriasis is a common, chronic condition in which the skin develops red, itchy patches and thick, silvery scales.

Psoriasis can occur anywhere on the body but is commonly found on the elbows, knees, scalp, trunk and nails.

Psoriasis affects approximately 2 percent of people in the United States, according to the National Psoriasis Foundation. It can affect anyone at any age but is most commonly diagnosed between ages 15 and 35.

There are five types of psoriasis: plaque, guttate, inverse, pustular and erythrodermic. Plaque psoriasis is the most common type.

Psoriasis is a chronic, autoimmune disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.

Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. These skin patches are typically red, itchy, and scaly. They may vary in severity from small and localized to complete body coverage.

The most common form is known as plaque psoriasis or psoriasis vulgaris. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery-white scaly skin. These areas are called plaques and are most commonly found on the elbows, knees, scalp, and back.

Psoriasis is an autoimmune disease that causes skin cells to grow at a rapid pace. This leads to the accumulation of cells on the surface of the skin, creating raised red patches covered by a flaky, white buildup.

Psoriasis affects 125 million people around the world and can occur at any age. It most commonly shows up between the ages of 15 and 35.

The deep red color of the lesions is caused by inflammation in small blood vessels under the skin. The condition may improve or worsen with changes in immune system function and hormonal levels. The symptoms vary from person to person, but they’re usually fairly consistent over time in each individual.

The most common form of psoriasis is plaque psoriasis (psoriasis vulgaris). It appears as raised patches of red or white scaly areas on elbows, knees, lower back and scalp. Psoriatic lesions are areas where skin cells grow faster than normal. Skin cells typically reproduce every 28 to 30 days, but in people with psoriasis this process occurs much more rapidly: Skin cells reproduce every three to four days instead of one month.

The exact cause of psoriasis isn’t known but it’s likely due to a combination of genetic and environmental factors

Psoriasis is a common skin condition that can affect anyone. It causes cells to build up rapidly on the surface of the skin, forming itchy red patches and thick scales. Patches are typically found on the elbows, knees, scalp, lower back, face, palms, and soles of the feet, but can affect other places (fingernails, toenails, and mouth).

Psoriasis varies in severity from small, localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon.

Psoriasis is associated with other serious health conditions, such as diabetes, heart disease and depression.

Psoriasis is a chronic skin condition that causes skin cells to grow too quickly, resulting in thick, white, silvery, or red patches of skin. The body does not shed these extra skin cells. The extra skin cells form scales and red patches that are itchy and sometimes painful.

Psoriasis affects as many as 7.5 million people in the United States. It occurs equally in men and women and can occur at any age. However, it most commonly appears first between the ages of 15 and 25 years. Psoriasis may be mild with small areas of rash or severe with large areas affected.

Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get the patches on your elbows, knees, scalp, back, face, palms and feet. But they can show up on other parts of your body. Some people who have psoriasis also get a form of arthritis called psoriatic arthritis. It causes swelling and pain in and around the joints.

Psoriasis isn’t contagious. You can’t catch it from touching someone else who has it.

No one knows exactly what causes psoriasis, but it’s thought to be related to an immune system problem with T cells and other white blood cells, called neutrophils, in your body. T cells normally travel through the body to defend against foreign substances, such as viruses or bacteria. But if you have psoriasis, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection.

Your body responds by making new skin cells every few days instead of the usual 4 weeks. Those new skin cells move up to the outermost layer of skin too fast — in days rather than weeks. They pile up on the surface before they have a chance to mature, which is how

Psoriasis is a chronic skin condition that causes the rapid buildup of skin cells. This buildup of cells causes scaling on the skin’s surface. Inflammation and redness around the scales is fairly common. Psoriasis can develop on any part of the body and is associated with other serious health conditions, such as diabetes, heart disease, and depression. There is no cure for psoriasis, but it can be managed. Treatments include topical creams, phototherapy, and immune-suppressing drugs. Psoriasis is a type of autoimmune disease called psoriasis vulgaris. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious. The patches can range from a few spots of dandruff-like scaling to major eruptions that cover large areas. Most cases of psoriasis are mild or moderate, but some people face severe problems with cracked, bleeding skin and joints so painful it hinders their ability to perform basic tasks like walking or grasping objects. Psoriatic arthritis can cause permanent joint damage if left untreated, and having psoriasis increases your risk of heart attack and stroke.
