Causes of psoriasis
Although the exact cause of
psoriasis is not known, a wide number of factors interplay to cause this debilitating disorder. The defense system of the body known as the immune system is affected by these factors, which results in the formation of additional blood vessels and increased number of skin cells.
Psoriasis is said to be a hereditary (genetic) disorder, as it tends to affect members of the same family. Increased stress (both physical and emotional) has been proposed to precipitate the occurrence of psoriasis in individuals who are genetically prone to develop psoriasis. Streptococcal throat infections (tonsillitis), Candida infections (thrush) and certain yeast infections can result in flaring up of the psoriasis. Some of the medications such as lithium, beta-blockers and antimalarials have been known to aggravate the existing psoriasis. Other factors such as obesity, increased alcohol intake or smoking also have also been associated either with the occurrence or with the severity of the disorder.1,2
