All You Need To Know About Psoriasis and How to Manage the Disease
2 Causes of Psoriasis
According to science, psoriasis could be hereditary where 10% of people could inherit one or more of the genes that put them at risk of the conditon. Those having such genes and exposed to triggers (external factors causing psoriasis) are at increased risk of contracting the disease. Weakened immunity and poor hygiene can also lead to psoriasis but somehow the real cause of the disease is still a bone of contention and a subject of ongoing research.

3 Types of Psoriasis and how it occurs
Psoriasis occurs from heightened activity of white blood cells or lymphocytes. Inflammatory substances cause the skin cells to multiply faster than usual which reach the skin surface where they then die. The continuous activity causes a red plaque on the skin surface along with white scales which is characteristic of the condition.
Plaque psoriasis: Most common condition with red inflamed skin lesions and silver scales. Common to the knees and back.
Guttate Psoriasis: Common in young children. Appears as pinkish spots on the arms and legs.
Inverse psoriasis: Commonly found under armpits, groins, beneath the breasts, genital folds and anal area. Characterized by shiny red lesions.
Erythrodermic psoriasis: Appears as scaly red flaky skin that continues to shed. Can occur all over the body.
Pustular Psoriasis: Common to adults. Appears as red inflamed skin with pus filled blisters. Can be localized or all over the body.
