Psoriasis: Causes, Symptoms & Effective Treatment Options

What is Psoriasis?

Psoriasis is a chronic skin condition that causes red, scaly patches to appear on the skin. It happens when the immune system triggers rapid skin cell turnover, leading to an accumulation of dead cells on the surface. Psoriasis is not contagious, but it can be lifelong and often occurs in cycles, with flare-ups and periods of remission.

Although it can appear anywhere on the body, psoriasis most commonly affects the scalp, elbows, knees, lower back, and nails.

What Causes Psoriasis?

Psoriasis is an autoimmune disorder, meaning the body’s immune system mistakenly attacks healthy skin cells. This leads to faster-than-normal skin regeneration, causing thick, inflamed patches.

Common triggers include:

• Genetics – If someone in your family has psoriasis, your risk is higher
• Stress – Emotional stress can trigger or worsen symptoms
• Infections – Bacterial or viral infections (like strep throat) can lead to flare-ups
• Weather – Cold, dry climates may worsen symptoms
• Skin Trauma – Injuries, cuts, burns, or insect bites can cause new psoriasis patches
• Certain Medications – Some drugs (like beta-blockers or lithium) can aggravate psoriasis
• What are the Symptoms of Psoriasis?

Psoriasis symptoms can vary based on the type and severity, but common signs include:

Red, inflamed patches covered with thick, silver-white scales
Itching, burning, or soreness in affected areas
Dry, cracked skin that may bleed
Thickened, pitted, or ridged nails
Painful, swollen joints (in psoriatic arthritis)

Types of Psoriasis

There are different types of psoriasis, each with unique characteristics:

1. Plaque Psoriasis (Psoriasis Vulgaris)

Most common type (about 80-90% of cases)
Red patches covered with silvery-white scales
Often found on scalp, elbows, knees, and lower back

2. Guttate Psoriasis

Small, droplet-shaped red spots
Usually triggered by infections like strep throat
Common in children and young adults

3. Inverse Psoriasis

Smooth, shiny, red patches in body folds (underarms, under breasts, groin)
Can worsen with sweat and friction

4. Pustular Psoriasis

White pustules (blisters) surrounded by red skin
Can be localized (hands & feet) or widespread

5. Erythrodermic Psoriasis

Severe, full-body redness, peeling, and itching
Rare but requires urgent medical attention

Is Psoriasis Curable?

While there is no permanent cure, psoriasis can be effectively managed with the right treatment plan.

Treatment Options for Psoriasis

1. Topical Treatments (For Mild Psoriasis)

Corticosteroid creams – Reduce redness and itching
Vitamin D analogs – Slow down skin cell production
Coal tar & salicylic acid – Help remove scales

2. Phototherapy (Light Therapy)

Narrowband UVB therapy – Slows excessive skin growth
PUVA therapy – Combines UV light with a medication (psoralen) for better results

3. Systemic Medications (For Moderate to Severe Psoriasis)

Biologics (e.g., Adalimumab, Etanercept, Secukinumab) – Target immune system overactivity
Oral medications (e.g., Methotrexate, Cyclosporine) – Suppress the immune response

4. Lifestyle & Home Care

• Moisturize daily to reduce dryness and irritation
• Avoid harsh soaps & hot showers to prevent skin damage
• Manage stress through meditation, yoga, or therapy
• Follow a healthy diet rich in anti-inflammatory foods

Can Psoriasis Spread?

No, psoriasis is not contagious and does not spread from person to person. However, it may worsen over time if left untreated.

Psoriatic Arthritis: Should You Be Concerned?

Some people with psoriasis develop psoriatic arthritis, which causes joint pain, swelling, and stiffness. Early diagnosis and treatment can prevent joint damage.
