(There are as many as 25 genetic mutations that make someone more likely to develop psoriasis.) But only 2 to 3 of people will develop the disease, according to the national Psoriasis foundation (NSF). Therefore, researchers believe that psoriasis is caused by a certain combination of genes that spring into action after being exposed to a trigger. Common triggers include stress, an infection (like strep throat and certain medications (like lithium). Cold, dry weather and sunburns may also trigger psoriasis flares. When someone with psoriasis is exposed to a trigger, their immune system scrambles to defend itself by producing T cells, a type of white blood cell that helps ward off infections and other diseases. With psoriasis, however, t cell-production goes into overdrive, eventually causing inflammation and faster-than-usual growth of skin cells, leading to psoriasis symptoms. Psoriasis symptoms The signs and symptoms of psoriasis vary depending on the type and severity of the skin disease.
The lesions look like large sheets rather than small spots, as if the area has been burned, and tend to be severely itchy and painful. A flare-up can trigger swelling, infection, and increased heart rate. Psoriasis is not contagious—its a genetic, autoimmune disease. Psoriasis lesions cannot infect other people; likewise, people cant catch psoriasis from someone else, whether through touching, sexual contact, or swimming in the same pool. Its unclear, however, whether a majority of the general public is aware of this fact. In a small 2015 survey in the. Journal of the American Academy of Dermatology, about 60 of people said they thought that psoriasis was infectious, while 41 said they thought the lesions looked contagious.

An estimated 10 of people inherit at least one of the genes that can cause psoriasis.
bumps filled with white pus) appear on the skin. In a typical cycle, the skin will turn red, break out in pustules, and then develop scales. There are three types of pustular psoriasis: von Zumbusch pustular psoriasis (which appears abruptly and can be accompanied with fever, chills, and dehydration palmoplantar pustulosis (which appears on the soles of the feet and the hands and acropustulosis (a rare form of psoriasis that forms. Guttate psoriasis is a type of psoriasis that appears as red, scaly teardrop-shaped spots. (The word guttate is Latin for drop.) During a flare-up, hundreds of lesions can form on the arms, legs, and torso, although they can also appear on the face, ears, and scalp. Guttate is the second most common type of psoriasis, occurring in about 10 of all people with the disease. Its most likely to appear in people who are younger than 30, oftentimes after they develop an infection like strep throat. Inverse psoriasis is a type of psoriasis that appears as smooth, bright red lesions in the armpit, groin, and other areas with folds of skin. Because these regions of the body are prone to sweating and rubbing, inverse psoriasis can be particularly irritating and hard to treat. Erythrodermic psoriasis is rare but can require immediate treatment or even hospitalization.

Research published in haircuts 2015 in the. Journal of Clinical Medicine suggested that infants and children with psoriasis may be particularly likely to be misdiagnosed with eczema because they may have less scaling than adults. Related: Whats That Rash? Back to top, types of psoriasis, psoriasis can range in severity, from mild patches to severe lesions that can affect more than 5 of the skin. There are five types of the disease: plaque psoriasis, pustular psoriasis, guttate psoriasis, inverse psoriasis, and erythrodermic psoriasis. Some people will have one form, whereas others will have two or more. Plaque psoriasis appears as red patches with silvery white scales, or buildup of dead skin cells, called plaques. Its the most common type of psoriasis, affecting up to 90 of all people with the disease, according to the aad.

Psoriasis is a disease in which red, scaly patches form on the skin, typically on the elbows, knees, or scalp. An estimated.5 million people in the United States will develop the disease, most of soorten them between the ages of 15 and. Many people with psoriasis experience pain, discomfort, and self-esteem problems that can interfere with their work and social life. Although the exact cause of psoriasis is unknown, researchers say the disease is largely genetic—its caused by a combination of genes that send the immune system into overdrive, triggering the rapid growth of skin cells that form patches and lesions. Eczema, a dermatologist can likely tell the difference between psoriasis and eczema, but to the untrained eye, these skin conditions can appear similar. Generally speaking, psoriasis appears as thick, red patches that have a scaly buildup on top, according to the American Academy of Dermatology (AAD). These lesions are usually well defined, whereas eczema tends to cause a rash and be accompanied by an intense itch. In addition, psoriasis tends to occur on the outside of the knees and elbows, and on the lower back and scalp; eczema usually covers the elbow and knee creases and the neck or face.
