Psoriasis is a chronic autoimmune skin condition that speeds up the life cycle of skin cells, causing red, scaly patches, itching, and inflammation. It is not contagious and can vary in severity from mild to severe.

The exact cause of psoriasis is unknown, but it is believed to be linked to an overactive immune system that mistakenly attacks healthy skin cells. Genetics, stress, infections, and environmental factors can trigger or worsen the condition.

No, psoriasis is not contagious. You cannot catch it from someone else through physical contact, sharing personal items, or being in close proximity.

Symptoms vary, but the most common include:

• Red patches with silvery-white scales

• Dry, cracked skin that may bleed

• Itching, burning, or soreness

• Thickened or ridged nails

• Stiff or swollen joints (in psoriatic arthritis)

There are several types, including:

• Plaque Psoriasis (Psoriasis Vulgaris) – The most common type, characterized by red, scaly patches.

• Guttate Psoriasis – Small, drop-like spots often triggered by infections.

• Inverse Psoriasis – Red, shiny patches in skin folds (under breasts, armpits, groin).

• Pustular Psoriasis – White pustules surrounded by red skin, usually on hands and feet.

• Erythrodermic Psoriasis – A severe form causing widespread redness, peeling, and extreme discomfort.

Yes, psoriasis is linked to psoriatic arthritis (PsA), which causes joint pain, stiffness, and swelling. It is also associated with other health conditions like heart disease, diabetes, and depression.

Triggers vary per person but may include:

• Stress

• Infections (such as strep throat)

• Cold or dry weather

• Skin injuries (cuts, burns, insect bites)

• Certain medications (beta-blockers, lithium, NSAIDs)

• Smoking and excessive alcohol consumption

A dermatologist typically diagnoses psoriasis through a physical exam and by reviewing medical history. In some cases, a skin biopsy may be done to rule out other conditions.

There is no cure, but treatments can help manage symptoms:

• Topical Treatments: Corticosteroids, vitamin D analogs, moisturizers.

• Phototherapy: Controlled exposure to UV light.

• Systemic Medications: Oral or injectable drugs like biologics and immunosuppressants for severe cases.

• Lifestyle Changes: Stress management, a healthy diet, and avoiding triggers can help reduce flare-ups.

Yes! With proper management, people with psoriasis can lead healthy, fulfilling lives. Support groups, lifestyle adjustments, and the right treatment plan can improve quality of life.
