The psoriasis skin problems leads to the occurrence of thick red plaques that are usually accompanied by silvery scales. The areas that are commonly affected include scalp, knees, elbows and lower back. In some cases, psoriasis can also occur in body folds and nails. This is not a contagious disease and cannot be transmitted to any other person.
Different Symptoms of Psoriasis
The initial symptoms of psoriasis include small red bumps which generally become large and scaly. The appearance of the skin changes and starts to bleed if scales are rubbed or peeled. Apart from that, it has been observed on a number of occasions that it can lead to rashes and the nails become crumbly, cracked and pitted.
The Various Causes of Psoriasis
The definite causes of psoriasis skin problems are still unknown but experts believe that combination of different factors causes this disease. Immune system abnormality leads to skin inflammation which triggers the development of new skin cells rapidly. Generally, replacement of skin cells happens every twenty eight to thirty days. When a person is affected with psoriasis, the new cells move to skin surface every 3 to 4 days. The silver scales are caused by old cells build-up. Psoriasis outbreaks generally occur from different factors like skin injury (scrapes, cuts or surgery), strep infections as well as emotional stress.
The Treatment for Psoriasis
A wide range of treatments are available for psoriasis. While some treatments are aimed towards slowing down new cell production, others relieve dry skin and itching. Depending on the rash extent and other factors like overall health, age and body part affected, the appropriate treatment plan is selected by the doctor. Some of the common treatments for psoriasis are:
- Moisturizers (to treat dry skin)
- Steroid creams
- Vitamin D cream (Vitamin D in pills and food cannot effect psoriasis that is why this special form is ordered by the doctor)
- Retinoid creams
- Coal Tar (available in bath solutions, shampoos and lotions, it can treat scalp psoriasis)
For severe to moderate cases of psoriasis skin problems different methods are used by doctors which include:
- Light Therapy – Ultraviolet light of some special form combined with psoralen medicine is used for treating severe cases of psoriasis.
- Cyclosporine – This is an immune-suppressant drug used in rare cases when other modes of treatment fail. Regular monitoring is required as this medicine can cause harm to the kidneys and increase blood pressure.
- Biologic Therapies – Some other new drugs for treatment of psoriasis include Humira, Amevive, and Enbrel. These medicines are given in the form of injections which blocks the immune system of the body towards producing an autoimmune disease like psoriasis.
Even though psoriasis skin problems are untreatable but research is in progress to find better treatments and possible cure in future.
