Overview of Psoriasis

Psoriasis is a long-term, chronic autoimmune skin condition that causes skin cells to multiply rapidly, resulting in thick, scaly, red patches that are often itchy or painful. It commonly affects the scalp, elbows, knees, back and even fingernails or toenails. Psoriasis is not contagious but can significantly impact quality of life due to its visible symptoms and discomfort. While there is no permanent cure, effective treatments can help manage the condition and reduce flare-ups.

Types of Psoriasis

1. Plaque Psoriasis: Most common type; thick, raised, red patches covered with silvery-white scales.

2. Scalp Psoriasis: Affects the scalp with flaky, crusty skin that resembles dandruff but is more persistent and inflamed.

3. Guttate Psoriasis: Appears as small, dot-like lesions; often triggered by infections like strep throat.

4. Inverse Psoriasis: Smooth, red patches found in skin folds such as underarms, groin, or under the breasts.

5. Genital Psoriasis: Affects the skin of the genital area and may cause itching, discomfort, or pain.

6. Nail Psoriasis: Causes pitting, thickening, or discoloration of fingernails or toenails; nails may also separate from the nail bed.

7. Pustular Psoriasis: Characterised by white pustules surrounded by red skin; may be localized or widespread.

8. Erythrodermic Psoriasis: A rare but severe form causing widespread redness, itching, and shedding of skin in sheets.

Flaky skin on the scalp resembling dandruff

Skin rash that may worsen during cold weather or due to stress

Causes of Psoriasis

Overactive immune response causing rapid skin cell turnover

Genetic predisposition (runs in families)

Infections, such as strep throat, triggering flare-ups

Skin injury or trauma (Koebner phenomenon)

Certain medications like beta-blockers or antimalarials

Stress, which can trigger or worsen symptoms

Environmental factors like cold, dry weather

Hormonal changes or smoking

Complications in Psoriasis

Nail damage causing loss of nail function or separation from nail bed

Risk Factors of Psoriasis

Family history of psoriasis or autoimmune diseases

Being aged between 15 to 35 years when symptoms first appear

Experiencing frequent infections, especially strep throat
