5 Psoriasis Triggers And How It Differs On Skin

Psoriasis is widely known as a skin disease that can exist as patches on skin surfaces. The condition varies for those suffering from it. It can be a mild itchy condition for some, but it might be a long-term chronic disease for others. To avoid long lasting effects, here are some common triggers that you should be aware of.  

What Are the Triggers of Psoriasis?

Psoriasis signs and symptoms differ based on the type of psoriasis you have. The following are the top five psoriasis symptoms:

  • Rashes or red, inflamed patches of skin, typically covered in loose, silver-coloured scales; in extreme instances, the plaques can expand and merge into one another, covering large regions.

  • Itchy, inflamed skin that cracks and bleeds

  • Scratches on the affected skin cause little patches of blood.

  • Discolouration and pitting of your fingernails and toenails, as well as crumbling or detachment of the nails from the nail bed.

  • Scaly plaques on the surface of the scalp.

Psoriasis may also lead to psoriatic arthritis, which causes swollen, achy joints. This painful joint condition affects between 10% and 30% of patients who have psoriasis.

What Causes Flare-Ups?

Every individual who suffers from this condition has a unique set of triggers. Things that cause your psoriasis to flare up may have no effect on another person's psoriasis.

You'll be able to better regulate your symptoms if you figure out what causes your skin to flare up.

Psoriasis is a disorder of the immune system. Certain triggers may aggravate your symptoms, such as:

  • Cold, dry weather: Any climate that alleviates dry skin will be beneficial. Spend some time in warm, sunny weather with a high level of humidity.
  • Stress: Keep your cool and try to relax. When you're stressed, flares are more likely to occur.
  • Certain Medication: Some “beta-blocker” medicines used to treat high blood pressure and heart disease, lithium, a bipolar disorder treatment, and malaria medicines are among them. If you have psoriasis and are being treated for any of these conditions, tell your doctor.
  • Infections: A small list of infections, such as strep throat and tonsillitis, may cause a unique kind of psoriasis outbreak. It appears as little drops that mostly appear on your chest and limbs. Infection with HIV may exacerbate the problem.
  • Skin Injury: Even minor cuts, bruising, and burns might trigger an outbreak in some individuals. Even tattoos and insect bites have the potential to cause a new lesion. To prevent a break in your skin, put on gloves or an additional layer of clothing.
  • Alcohol: Drinking, particularly excessive drinking in young men, may worsen symptoms and make treatment more difficult. Certain psoriasis medications might have dangerous side effects when used with alcohol, particularly for women in their reproductive years.
  • Smoking: Tobacco use or exposure to secondhand smoke increases your chance of developing psoriasis and worsens existing problems.

Psoriasis With Different Skin Tones

Psoriasis can affect people of all skin tones, although it appears differently on darker skin.

Psoriasis in African Americans is often purplish in hue, with gray-scaled scaling. Psoriasis may be dark brown and difficult to spot on extremely dark skin.

Lighter in colour, Hispanic skin is prone to psoriasis that is dark pinkish in hue and has a silvery-white scale.

Furthermore, areas that are lighter or darker than the surrounding skin may persist for some time after psoriasis has cleared on certain skin types (dyspigmentation).

These are not scars, and they will fade with time, which might take anywhere from a few months to a year or more. Your dermatologist or a skin doctor may be able to help them clean up faster. If the look of the patches disturbs you, seek professional advice.

This particular skin can negatively impact your self-confidence. Do bear in mind that with appropriate care from a trained medical professional, this condition can be managed well and symptoms can improve with time.
