Psoriasis Guide

What is Psoriasis?

Psoriasis is a chronic autoimmune skin condition that causes rapid skin cell buildup, leading to scaling, inflammation, redness, and discomfort. It is a lifelong condition that can vary in severity, with periods of flare-ups and remission. While it primarily affects the skin, psoriasis is also linked to other health issues, such as psoriatic arthritis and cardiovascular disease.

Classify Psoriasis

• Condition – Psoriasis is a chronic inflammatory skin disorder caused by an overactive immune system. It is classified as an autoimmune disease because the body’s immune system mistakenly attacks healthy skin cells, triggering excessive skin cell production.

Psoriasis Statistics

• An estimated 125 million people worldwide (about 2–3% of the global population) have psoriasis.
• In the United States, around 7.5 million adults are affected.
• Psoriasis can develop at any age, but it is most common between 15 and 35 years old.
• Up to 30% of people with psoriasis also develop psoriatic arthritis, a painful condition that affects the joints.

Types of Psoriasis

There are several types of psoriasis, each with distinct characteristics:

1. Plaque Psoriasis (Psoriasis Vulgaris) – The most common type, causing raised, red patches covered with silvery-white scales.
2. Guttate Psoriasis – Small, red, drop-shaped spots, often triggered by infections like strep throat.
3. Inverse Psoriasis – Smooth, shiny red patches in skin folds (e.g., under the breasts, armpits, or groin).
4. Pustular Psoriasis – White pustules (blisters filled with pus) surrounded by red skin, usually on the hands and feet.
5. Erythrodermic Psoriasis – A severe, life-threatening form that causes widespread redness, severe pain, and peeling of the skin.
6. Nail Psoriasis – Causes pitting, discoloration, and nail detachment.
7. Psoriatic Arthritis – A combination of psoriasis and joint inflammation, causing pain, swelling, and stiffness.

Health Signs and Symptoms

Early Signs:

Psoriasis can start with mild redness, small patches of scaling, or irritation in specific areas.

Common Symptoms:

• Red patches of skin covered with silvery scales
• Itching, burning, or soreness in affected areas
• Cracked or dry skin that may bleed
• Thickened, ridged, or discolored nails
• Joint pain, stiffness, and swelling (in psoriatic arthritis)

Anatomy and Physiology

Psoriasis primarily affects the skin, but it can also impact:

• Immune System – Overactive immune response leads to inflammation.
• Joints – Causes psoriatic arthritis, leading to stiffness and swelling.
• Nails – Thickening, ridges, and discoloration can occur.
• Scalp – Many people experience psoriasis on the scalp, leading to dandruff-like flakes.

Causes of Psoriasis

Psoriasis is caused by an immune system malfunction that speeds up skin cell production.

Common Causes:

1. Genetics – Family history increases the risk.
2. Immune System Dysfunction – The immune system mistakenly attacks healthy skin cells.
3. Environmental Factors – Triggers such as infections, stress, and weather changes.

Common Triggers of Psoriasis

1. Stress – Emotional or physical stress can worsen psoriasis.
2. Infections – Strep throat and skin infections can trigger flares.
3. Cold, Dry Weather – Harsh weather conditions can dry out the skin.
4. Skin Injuries – Scratches, cuts, and sunburns can trigger new patches.
5. Certain Medications – Beta-blockers, lithium, and anti-malarial drugs can trigger psoriasis.
6. Smoking & Alcohol – Both increase inflammation and worsen symptoms.

Complications of Psoriasis

If not treated, symptoms may worsen and impact daily life. Potential complications include:

• Psoriatic Arthritis – Joint pain and stiffness.
• Cardiovascular Disease – Higher risk of heart attacks and strokes.
• Diabetes & Metabolic Syndrome – Increased risk of type 2 diabetes.
• Mental Health Issues – Depression and anxiety due to the visible nature of the disease.
• Eye Problems – Uveitis (eye inflammation) can occur.

Risk Factors

• Family History – Genetic predisposition increases the likelihood.
• Age – Can develop at any age, but most common between 15-35 years.
• Obesity – Excess weight can worsen psoriasis.
• Smoking & Alcohol Use – Increases severity and risk of flare-ups.
• Chronic Stress – Weakens the immune system and triggers inflammation.

Psoriasis Stages

1. Mild – Small patches of scaling and redness affecting less than 3% of the body.
2. Moderate – Covers 3-10% of the body, causing discomfort.
3. Severe – Covers more than 10% of the body, causing significant pain and itching.

Prevention

While psoriasis can’t be cured, symptoms can be managed by:

• Reducing stress with relaxation techniques.
• Moisturizing regularly to prevent dryness.
• Avoiding known triggers like smoking, alcohol, and certain medications.
• Maintaining a healthy diet and weight.

Psoriasis Diagnosis

Doctors diagnose psoriasis based on a physical exam and, in some cases, a skin biopsy.

Tests & Examinations:

• Skin Examination – A dermatologist visually inspects affected areas.
• Skin Biopsy – A small skin sample is analyzed under a microscope.
• Blood Tests – To rule out other conditions like lupus.
