Skin Psoriasis Causes And Triggers You Probably Don’t Know

Skin Psoriasis Causes And Triggers That May Surprise You

In skin Psoriasis Causes turns your skin cells into Type A overachievers: They grow about five times faster than normal skin cells. And your body can’t keep up. The old ones pile up instead of sloughing off, making thick, flaky, itchy patches.Why do these cells go a little haywire? There’s more going on under the surface of this skin disease.Researchers think something sets off your immune system. The exact reason is a mystery. But it’s likely a combination of genetics and triggers.

Your Genes and Your Immune System

Little bits of your DNA, called genes, are instructions for your cells. They control things like your eye and hair color, if you can taste certain things, and other ways your body works. Some genes are only active at certain times.When you have psoriasis, the genes that control your immune system signals get mixed up. Instead of protecting your body from invaders as it’s designed to do, it promotes inflammation and turns skin cells on overdrive.Scientists have found about 25 genes that are different in people with psoriasis. They think it takes more than one to cause the disease, and they’re looking for the main ones.

Triggers

If you’ve got the right combination of genes, something can turn psoriasis “on” or start a flare.

Skin injury: A cut, scrape, bug bite, infection, bad sunburn, or even too much scratching can trigger the condition.

Infections: Strep infections, in particular, are linked with guttate psoriasis, which looks like small, red drops. Kids will often have strep throat before their first flare. Earaches, bronchitis, tonsillitis, or a respiratory infection such as a cold, the flu, or pneumonia can also set off your skin problems.

HIV : Psoriasis usually is worse in the beginning stages of the disease, but then it gets better after you start certain treatments.

Medications : Some can make psoriasis worse.

  • Lithium, which treats bipolar disorder and other mental illnesses
  • High blood pressure and heart medicines, including propranolol(Inderal) and other beta blockers, ACE inhibitors, and quinidine
  • Antimalarial, including chloroquine, and hydroxychloroquine(Plaquenil), and quinacrine
  • Indomethacin (Indocin), which treats inflammation

Stress : Scientists think your immune system may respond to emotional and mental pressures the same way it does to physical problems like injuries and infections.

Weight : People who are obese tend to get plaques in their skin creases and folds.
