What is psoriasis?
Psoriasis is a long-term, non-contagious inflammatory condition causing scaly skin patches. Joints can also be involved.
Causes, symptoms and diagnosis
1. Definition and causes Immune changes affect skin-cell turnover. Genetics and triggers may contribute to flares, but appearance and severity vary. 2. Symptoms and assessment Scaly plaques can occur on elbows, knees or scalp. Nail changes and joint pain or stiffness may accompany them. Examination guides diagnosis. 3. Care and treatment Moisturizers, topical medicines, light therapy or systemic care are chosen by extent and impact. Benefits and risks need follow-up; no single natural product is a cure.
Warning signs and prevention
4. When to seek help Swollen painful joints, extensive or rapidly worsening rash, fever or loss of function need assessment. Early joint review may protect function. 5. Prevention and daily life Smoking, alcohol or stress affect some people. Gentle skin care, tracking triggers and long-term review support quality of life.
