Causes Behind Psoriasis!

Psoriasis is a skin condition marked by red, itchy and scaly patches on the skin although the problem of psoriasis extends to even deeper parts under the skin. People who suffer from psoriasis face an increased likelihood of contracting other serious medical conditions such as cardiovascular diseases, diabetes, and psoriatic arthritis.

The condition has no definite cure but the symptoms can be treated and managed.

Causes of psoriasis:

The following factors are proven to have contributed to cases of psoriasis:

  1. HIV: Human immunodeficiency virus adversely affects the immune system and increases susceptibility of all kinds of infections and diseases. HIV-positive individuals have been found to have an increased risk of psoriasis than HIV-negative people.
  2. Genetics: More than 32% of the cases of psoriasis have been linked to genes. In case of identical twins, if one twin has the disease, the other has a 70% chance of getting it too. There are several genes associated with the disease and most of these genes are related to the immune system. T cells (lymphocytes which affect cell specific immunity) can also cause psoriasis.
  3. Medication: Antimalarial, anti-inflammatory and blood pressure medicines can cause psoriasis as a side effect. The disease is also an effect of withdrawal from topical steroid creams and other steroid-based medication.
  4. Other diseases: Diseases like strep throat, chronic infections, skin infections and stress may be responsible for the condition. Other factors like obesity, alcoholism, skin dryness and smoking can also lead to psoriasis. If you wish to discuss about any specific problem, you can consult a Dermatologist.
