Psoriasis

Description and Symptoms

Psoriasis sufferers produce the new cells at a much faster rate than normal, resulting in a raised, red patch of skin, which can be overlaid with white or silver scales.

Chronic plaque psoriasis is the most common type and most often occurs on the elbows and knees, scalp, lower back, genitals, and can sometimes occur on the trunk and limbs.

The nails can also be affected and can appear like a fungal infection.

Psoriasis of the scalp will affect most people who develop psoriasis. Scaliness occurs around the hairline, and is often itchy. A family history of psoriasis is common.

Who does it Affect?

Factors such as infection, sunburn, stress, hormonal changes or taking certain medications can aggravate the problem.

Drugs such as lithium and withdrawal from cortisone treatment are thought to exacerbate psoriasis, as well as cigarette smoking and alcohol consumption. Beta-blockers, antimalarials, and NSAIDs also have been implicated.

The National Psoriasis Foundation has reported that researchers now have evidence that psoriasis is an autoimmune disorder.

There is another school of thought who believes the appearance of the skin is caused by the body attempting to rid itself of toxins, and that the problem is not a true "skin" problem.

This theory bases itself on the belief that a sluggish elimination system is unable to cope and the toxins eventually make their way out through the skin. Diet and lifestyle is believed to play a significant role.
