Risk factors & Triggers

• Genetics – some people with psoriasis have a relative who also suffers from it, however psoriasis can also occur in people with no family history of the condition.  It is thought that there are complex genetic factors leading to the presence of psoriasis in some people. 
• Stress – stress can commonly trigger an exacerbation of psoriasis
• Smoking and alcohol – studies have shown that these can worsen psoriasis
• Weather – cold, dry weather tends to aggravate psoriasis, as already vulnerable skin becomes more prone to injury in dry conditions
• Medications – certain medications may trigger psoriasis, including lithium, beta blockers, non-steroidal anti-inflammatories (eg. Ibuprofen), and antimalarials
• Upper respiratory tract infection – there is a particular type of psoriasis (guttate psoriasis) that can emerge following an infection such as streptococcus (eg. Strep throat)

What are the symptoms of Psoriasis ?

• Red skin patches with a thick white/silvery scale
• Can be sparse large patches, or many small spots
• Often on the elbows, knees, lower back, torso, and scalp
• Plaques can be itchy and uncomfortable
• Can also cause nail and joint problems
• Flares can be upsetting and cause concern regarding abnormal skin appearance 

Is Psoriasis contagious?

No, you cannot catch psoriasis by coming into contact with someone who has it. Psoriasis is not an infection on the skin, but is due to inflammation caused by the body’s immune system.
