Psoriasis is an inherited disorder of the skin, which causes red, scaling bumps and patches on the skin. It is a chronic disorder, which means that the symptoms come and go throughout a person's life.
Psoriasis causes an increase in skin cells on the outer layer of the skin. In a healthy individual, skin cells mature and shed from the surface of the body about every 28 days. People with psoriasis shed skin cells every 3 to 4 days. The excess skin cells build up and form the skin lesions of psoriasis.
Causes and risks
The exact cause of psoriasis is unknown, but it is commonly believed that the body's immune system triggers the rapid growth and shedding of skin cells. Several genes have been linked to psoriasis, which tends to run in families. However, many people with psoriasis have no family history of the disease.
Suspected triggers include the following:
Agents that damage the skin, including chemicals, electricity, and infectious agents such as bacteria
- Body wide infections, including HIV
- Excessive scratching
- Hormonal changes
- Injuries to the skin, including sunburn
- Seasonal changes in climate
- Some medicines, including beta-blockers, antimalarials, and NSAIDs
- Strep throat
Signs and symptoms
Following are the five major types of psoriasis, each with its own characteristic skin lesions:
Erythrodermic psoriasis, which causes reddening and swelling of large areas of skin
Guttate psoriasis, which causes small skin lesions that look like drops of fluid
Inverse psoriasis, which causes smooth red lesions in the folds of the skin
Plaque psoriasis, the most common type, which causes raised red skin lesions that develop silvery-white scales
Pustular psoriasis, which forms blisters filled with thick white material
Other symptoms of psoriasis are as follows:
- Crumbling or abnormal fingernails and toenails
- Thickening, cracking, and blistering of the palms or soles of the feet
The severity of symptoms may range from a mild cosmetic problem to a disfiguring, disabling condition.
Psoriasis cannot be prevented, but it can be controlled. Certain triggers may be controlled or eliminated to help curb the outbreaks. Take these measures to prevent flare-ups of psoriasis.
