What Causes Plaque Psoriasis-You Will Be Shocked !

Plaque psoriasis is a chronic autoimmune condition that primarily affects the skin. It is the most common form of psoriasis, characterized by the appearance of raised, inflamed, red patches (plaques) covered with a silvery-white buildup of dead skin cells. These plaques can occur anywhere on the body but are most frequently found on the scalp, elbows, knees, and lower back.

Causes:

Plaque psoriasis is an autoimmune disorder where the immune system mistakenly speeds up the lifecycle of skin cells. This causes skin cells to accumulate rapidly, leading to the thick, scaly patches. Although the exact cause is unknown, genetic and environmental factors play a significant role.

Triggers:

Certain factors can exacerbate plaque psoriasis, including:

  • Stress
  • Infections (like strep throat)
  • Skin injuries (cuts, scrapes, or sunburns)
  • Cold, dry weather
  • Certain medications (e.g., beta-blockers, lithium)
  • Alcohol or smoking

Treatment Options:

There’s no cure for plaque psoriasis, but treatments aim to reduce symptoms and improve quality of life. Options include:

  1. Topical Treatments:
    • Corticosteroids
    • Vitamin D analogs (e.g., calcipotriol)
    • Coal tar or salicylic acid preparations
  2. Phototherapy:
    • Controlled exposure to ultraviolet (UV) light
  3. Systemic Treatments:
    • Oral medications (e.g., methotrexate, cyclosporine)
    • Biologics (e.g., adalimumab, secukinumab)

Managing Plaque Psoriasis:

  • Keeping the skin moisturized
  • Avoiding known triggers
  • Following prescribed treatments
  • Seeking regular medical advice for effective management
