4 Things You Need To Know About Psoriasis

Some Common Causes Of Psoriasis

The causes of psoriasis remain a mystery, but researchers believe there are genetic and environmental components involved. In people who are genetically predisposed to develop psoriasis (usually an inherited gene mutation), the skin condition may be set off by any number of environmental stressors or traumas, which are called “flares.”

Flares can include bug bites, scrapes, cuts, bad sunburns, and excessive scratching. Flares are usually some form of skin injury, an infection, and sometimes even HIV. Behavioural flares may include drinking alcohol in excess, smoking, and stress. There are also medications, such as lithium and blood pressure medications, that can cause a flare-up.
