These skin patches are typically red, itchy, and scaly. They may vary in severity from small and localized to complete body coverage.
It typically affects the outside of the elbows, knees or scalp, though it can appear on any location. Some people report that psoriasis is itchy, burns and stings. Psoriasis is associated with other serious health conditions, such as diabetes, heart disease and depression.
If you develop a rash that doesn't go away with an over-the-counter medication, you should consider contacting your doctor.
While scientists do not know what exactly causes psoriasis, we do know that the immune system and genetics play major roles in its development. Usually, something triggers psoriasis to flare. The skin cells in people with psoriasis grow at an abnormally fast rate, which causes the buildup of psoriasis lesions.
Men and women develop psoriasis at equal rates. Psoriasis also occurs in all racial groups, but at varying rates. About 1.9 percent of African-Americans have psoriasis, compared to 3.6 percent of Caucasians.
Psoriasis often develops between the ages of 15 and 35, but it can develop at any age. About 10 to 15 percent of those with psoriasis get it before age 10. Some infants have psoriasis, although this is considered rare.
Psoriasis is not contagious. It is not something you can "catch" or that others can catch from you. Psoriasis lesions are not infectious.Top
Psoriasis is a skin disorder driven by the immune system, especially involving a type of white blood cell called a T cell. Normally, T cells help protect the body against infection and disease. In the case of psoriasis, T cells are put into action by mistake and become so active that they trigger other immune responses, which lead to inflammation and to rapid turnover of skin cells.
In many cases, there is a family history of psoriasis. Researchers have studied a large number of families affected by psoriasis and identified genes linked to the disease. Genes govern every bodily function and determine the inherited traits passed from parent to child.
People with psoriasis may notice that there are times when their skin worsens, called flares, then improves. Conditions that may cause flares include infections, stress, and changes in climate that dry the skin. Also, certain medicines, including beta-blockers, which are prescribed for high blood pressure, and lithium may trigger an outbreak or worsen the disease. Sometimes people who have psoriasis notice that lesions will appear where the skin has experienced trauma. The trauma could be from a cut, scratch, sunburn, or infection.Top
Getting familiar with your psoriasis symptoms will help you be prepared for a conversation with your doctor.
Not everyone with psoriasis experiences the same symptoms, which can vary from person to person based on the severity and type of psoriasis. However, common symptoms may include:
Occasionally, doctors may find it difficult to diagnose psoriasis, because it often looks like other skin diseases. It may be necessary to confirm a diagnosis by examining a small skin sample under a microscope.
There are several forms of psoriasis. Some of these include:
Another condition in which people may experience psoriasis is psoriatic arthritis. This is a form of arthritis that produces the joint inflammation common in arthritis and the lesions common in psoriasis. The joint inflammation and the skin lesions don't necessarily have to occur at the same time.Top
No. Research studies have not shown it to be contagious from person to person. A person cannot catch it from someone else, and one cannot pass it to anyone else by skin-to-skin contact. Directly touching someone with psoriasis every day will never transmit the condition.Top
Although psoriasis is not contagious from person to person, there is a known hereditary tendency. Therefore, family history is very helpful in making the diagnosis.Top
Psoriasis is a fairly common skin condition and is estimated to affect approximately 1%-3% of the U.S. population. It currently affects roughly 7.5 million to 8.5 million people in the U.S. It is seen worldwide in about 125 million people. Interestingly, African Americans have about half the rate of psoriasis as Caucasians.Top
Psoriasis can show up anywhere—on the eyelids, ears, mouth and lips, skin folds, hands and feet, and nails. The skin at each of these sites is different and requires different treatments.
Light therapy or topical treatments are often used when psoriasis is limited to a specific part of the body. However, doctors may prescribe oral or injectable drugs if the psoriasis is widespread or greatly affects your quality of life. Effective treatments are available, no matter where your psoriasis is located.
Scalp psoriasis can be very mild, with slight, fine scaling. It can also be very severe with thick, crusted plaques covering the entire scalp. Psoriasis can extend beyond the hairline onto the forehead, the back of the neck and around the ears.
Facial psoriasis most often affects the eyebrows, the skin between the nose and upper lip, the upper forehead and the hairline. Psoriasis on and around the face should be treated carefully because the skin here is sensitive.
Treat sudden flares of psoriasis on the hands and feet promptly and carefully. In some cases, cracking, blisters and swelling accompany flares. Nail changes occur in up to 50 percent of people with psoriasis and at least 80 percent of people with psoriatic arthritis.
The most common type of psoriasis in the genital region is inverse psoriasis, but other forms of psoriasis can appear on the genitals, especially in men. Genital psoriasis requires careful treatment and care.
nverse psoriasis can occur in skin folds such as the armpits and under the breasts. This form of psoriasis is frequently irritated by rubbing and sweating.Top
Psoriasis can be mild, moderate or severe. Your treatment options may depend on how severe your psoriasis is. Severity is based on how much of your body is affected by psoriasis. (The surface area of the hand equals about 1 percent of the skin.) However, the severity of psoriasis is also measured by how psoriasis affects a person's quality of life. For example, psoriasis can have a serious impact on one's daily activities even if it involves a small area, such as the palms of the hands or soles of the feet.
Mild psoriasis covers less than 3 percent of the
Moderate psoriasis covers between 3 and 10 percent of the body.
If psoriasis covers more than 10 percent of your body, it is severe.
Topical treatments, such as moisturizers, over-the-counter and prescriptions creams and shampoos, typically are used for mild psoriasis.
Treating moderate to severe psoriasis usually involves a combination of treatment strategies. Besides topical treatments, your doctor your doctor may prescribe phototherapy (also known as light therapy). Your doctor may also prescribe systemic medications, including biologic drugs, especially if your psoriasis is significantly impacting your quality of life.Top
There are many effective treatment choices for psoriasis. Doctors generally treat psoriasis in steps based on the severity of the disease, size of the areas involved, type of psoriasis, where the psoriasis is located, and the patient's response to initial treatments.
Treatments applied directly to the skin may improve its condition. Doctors find that some patients respond well to ointment or cream forms of corticosteroids, vitamin D3, retinoids, coal tar, or anthralin. Bath solutions and lubricants may be soothing, but they are seldom strong enough to improve the condition of the skin. Therefore, they usually are combined with stronger remedies.
Natural ultraviolet (UV) light from the sun and controlled delivery of artificial UV light are used in treating psoriasis. It is important that light therapy be administered by a doctor. Spending time in the sun or a tanning bed can cause skin damage, increase the risk of skin cancer, and worsen symptoms.
Another type of UVB, called narrowband UVB, emits the part of the UV light spectrum band that is most helpful for psoriasis. Narrowband UVB treatment is superior to broadband UVB, but it is less effective than PUVA treatment (see next paragraph). At first, patients may require several treatments of narrowband UVB spaced close together to improve their skin. Once the skin has shown improvement, a maintenance treatment may be all that is necessary. However, narrowband UVB treatment is not without risk. It can cause more severe and longer lasting burns than broadband treatment.
For more severe forms of psoriasis, doctors sometimes prescribe medicines that are taken internally by pill or injection. This is called systemic treatment.
Chinese medicine is rooted in philosophies dating back thousands of years.Chinese treatment theory, we should treat the psoriasis start from the internal organs and blood, finally the skin problem will disappear. And the medicine should choose the safe and long term herb medicine. The treatment is to adjust your immune system and based on your own condition.
