What causes psoriasis?
Psoriasis is an autoimmune disease where your immune system mistakenly attacks healthy skin cells. This causes your body to produce new skin cells much faster than normal—every few days instead of about once a month.
The exact reason why the immune system overreacts isn't fully understood, but it likely involves a combination of genetic and environmental factors.
Genetic factors:
If psoriasis runs in your family, you're at higher risk. If one parent has psoriasis, there's about a 28% chance their child will develop it. That jumps to 65% if both parents have it.
Researchers have identified specific genes and genetic markers associated with psoriasis, though having these genes doesn't guarantee you'll develop the condition.
Common triggers that can cause flare-ups:
- Stress
- Skin injuries (cuts, scrapes, sunburn, bug bites)
- Infections like strep throat
- Certain medications (beta-blockers, antimalarial drugs, lithium)
- Smoking tobacco
- Excessive alcohol use
- Cold, dry weather
- Allergic reactions
While we can't pinpoint one single cause, understanding your personal triggers can help you manage your psoriasis more effectively.
