ANSWER

  • Certain factors may trigger psoriasis, including the following: Injury to the skin: Injury to the skin has been associated with plaque psoriasis. For example, a skin infection, skin inflammation, or even excessive scratching can trigger psoriasis.
  • Sunlight: Most people generally consider sunlight to be beneficial for their psoriasis. However, a small minority find that strong sunlight aggravates their symptoms. A bad sunburn may worsen psoriasis.
  • Streptococcal infections: Some evidence suggests that streptococcal infections may cause a type of plaque psoriasis. These bacterial infections have been shown to cause guttate psoriasis, a type of psoriasis that looks like small red drops on the skin.
  • HIV : Psoriasis typically worsens after an individual has been infected with HIV. However, psoriasis often becomes less active in advanced HIV infection.
  • Lithium: Drug used to treat bipolar disorder
  • Beta-blockers: Drugs used to treat high blood pressure
  • Antimalarials: Drugs used to treat malaria Emotional stress: Many people see a worsening of their psoriasis when emotional stress is increased.
  • Smoking : Cigarette smokers have an increased risk of chronic plaque psoriasis.
  • Alcohol: Alcohol is considered a risk factor for psoriasis, particularly in young to middle-aged men.
