Psoriasis
Psoriasis is a long-term, non-contagious autoimmune skin disorder that causes the rapid buildup of skin cells. This results in scaling on the skin’s surface, inflammation, redness, and sometimes painful lesions. It is a chronic condition that can vary in severity and often goes through cycles—flaring up for a few weeks or months and then subsiding.
Causes of Psoriasis:
The exact cause of psoriasis is not fully understood, but it is believed to be linked to an immune system malfunction that causes skin cells to regenerate too quickly. Common contributing factors include:
- Genetic predisposition (family history)
- Immune system dysfunction
- Stress and anxiety
- Skin injuries or infections
- Certain medications (e.g., beta-blockers, anti-malarials)
- Weather changes, especially cold and dry climates
- Alcohol and smoking
Symptoms of Psoriasis:
Symptoms vary from person to person and may include:
- Raised red patches of skin covered with thick silvery-white scales (commonly on elbows, knees, scalp, and lower back)
- Dry, cracked skin that may bleed
- Itching, burning, or soreness
- Thickened or ridged nails
- Joint pain or stiffness (in cases of psoriatic arthritis)
Types of Psoriasis:
There are several types of psoriasis, including:
- Plaque Psoriasis – Most common type, with thick red patches and silver scales
- Guttate Psoriasis – Small, dot-like lesions usually triggered by infections
- Inverse Psoriasis – Bright red, shiny lesions in skin folds
- Pustular Psoriasis – White pustules surrounded by red skin
- Erythrodermic Psoriasis – Severe, rare type with widespread redness and peeling
Treatment Options:
While there is no cure for psoriasis, it can be effectively managed. Dr. Preeti K Sheth offers a wide range of tailored treatment options based on the type, severity, and location of the condition:
- Topical Treatments: Steroid creams, vitamin D analogues, coal tar, and moisturizers to reduce scaling and inflammation
- Phototherapy (Light Therapy): Controlled exposure to natural or artificial UV light to slow down cell growth
- Systemic Medications: Oral or injectable drugs that affect the whole body, such as methotrexate or cyclosporine
- Biologic Therapies: Advanced targeted treatments that block specific immune responses causing psoriasis
- Lifestyle & Skincare Advice: Personalized recommendations for skincare routines, diet, and stress management
Prevention & Flare-up Management:
While psoriasis cannot always be prevented, flare-ups can be reduced or managed by:
- Avoiding known triggers (stress, smoking, certain foods, and infections)
- Keeping the skin well-moisturized
- Following prescribed treatments consistently
- Eating a balanced, anti-inflammatory diet
- Staying active and managing stress levels
- Regular follow-ups with a dermatologist
