Understanding Psoriasis Beyond the Skin
By Dr. Navaneeth K. Unni•Published on 2026-07-01•Patient Group: Adults
Clinical Overview & Pathophysiology
Psoriasis is often viewed as a simple skin disease characterized by red, scaly plaques. In reality, it is a chronic, systemic autoimmune inflammatory condition that affects multiple systems, including the joints and blood vessels.
Key Clinical Facts & Indicators
- Accelerated Skin Turnover: Skin cells mature in days rather than weeks, causing silvery scales.
- Symmetric Plaques: Typically located on elbows, knees, scalp, and the lower back.
- Systemic Inflammation: Associated with joint pain and stiffness (psoriatic arthritis).
- Nail Changes: Pitting, discoloration, or crumbling of finger and toe nails.
Lifestyle & Nutritional Guidelines
Psoriasis management requires addressing chronic systemic inflammation. A diet rich in anti-inflammatory omega-3 fatty acids, gluten reduction if sensitive, and daily skin moisturization are essential. Manage stress, as cortisol spikes are a primary trigger.
Frequently Asked Questions
Q: Can psoriasis affect the joints?Yes. Up to 30% of patients with psoriasis develop psoriatic arthritis, causing joint swelling, pain, and morning stiffness.
Q: What are common psoriasis triggers?Major triggers include emotional stress, skin injuries, cold weather, infections (like strep throat), and smoking.
