Psoriasis
What is it?
Psoriasis is a chronic inflammatory skin condition characterized by red, thickened, and scaly plaques.
Who gets psoriasis?
This condition affects 2–4% of the population and occurs in both males and females. Psoriasis can start at any age, with peaks of onset typically between the ages of 15–25 years and 50–60 years.
Causes
- Genetics: Family history increases the risk.
- Immune System Dysfunction: T-cells attack healthy skin cells, triggering inflammation.
- Triggers: Stress, infections, injuries to the skin, certain medications, and lifestyle factors like smoking or excessive alcohol use.
Symptoms
- Scaly Plaques: Red patches with a silvery-white scale, commonly found on the scalp, elbows, and knees.
- Shiny Skin Folds: In areas like the groin or under the breasts, plaques may appear moist and shiny.
- Persistent Lesions: Psoriasis plaques can remain untreated for long periods without intervention.
General Advice:
- Avoid smoking, excessive alcohol, and maintain a healthy weight.
- Stay informed about the condition and treatment options.
Topical Therapy:
Mild psoriasis is often managed with:
- Emollients
- Coal tar preparations on the scalp
- Salicylic acid
- Vitamin D analogs (e.g., calcipotriol)
- Topical corticosteroids
- Calcineurin inhibitors (e.g., tacrolimus)
Procedure
Systemic Therapy
For moderate to severe cases, systemic medications may be required, often combined with phototherapy.
Prevention Tips
- Avoid known triggers such as stress and injuries.
- Use gentle skincare products suitable for sensitive skin.
