Psoriasis: Complete Guide

What is Psoriasis?

Psoriasis is a chronic, autoimmune skin condition that speeds up the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. These extra skin cells form scaly, red, itchy patches that can be painful and unsightly. It’s non-contagious, but it’s long-lasting (chronic) and can fluctuate in severity — with flare-ups and remissions.

Symptoms of Psoriasis

Red patches of skin covered with thick, silvery-white scales.
Dry, cracked skin that may bleed.
Itching, burning, or soreness around patches.
Thickened, pitted, or ridged nails.
Stiff and swollen joints (in case of psoriatic arthritis).

Causes of Psoriasis

The exact cause isn’t fully understood but involves:

Immune system dysfunction — overactive T-cells attacking healthy skin cells.
Genetic predisposition — runs in families.
Environmental triggers such as:
Stress
Infections (like strep throat)
Skin injuries
Cold, dry weather
Certain medications (like beta-blockers, lithium)
Smoking and heavy alcohol use
