Dermatologists Warn Skin Conditions Often Signal Deeper Health Problems
During National Healthy Skin Month in November 2026, the American Academy of Dermatology is urging people to pay attention to skin changes that may point to internal health issues. Dermatologists say skin conditions can be early indicators of diabetes, insulin resistance, autoimmune diseases, and inflammatory bowel disease.
The American Academy of Dermatology is using National Healthy Skin Month in November 2026 to remind people that skin conditions are often the first visible sign of internal health problems.
Dermatologists say the skin barrier plays a central role in overall health, and changes in the skin can signal conditions including diabetes, insulin resistance, autoimmune diseases, and inflammatory bowel disease, sometimes before other symptoms appear.
The AAD is encouraging people to schedule professional skin examinations, not just for cancer screening, but as part of a broader health check. Skin changes such as unusual dryness, discoloration, rashes, or new growths can all point to systemic issues that need medical attention.
Diabetes, for example, can cause a range of skin changes including dark patches in skin folds, slow-healing wounds, and frequent skin infections. Autoimmune conditions like lupus and psoriasis often show up on the skin before affecting other organs.
Dermatologists also note that the skin barrier, when compromised, can allow allergens and irritants to enter the body more easily, contributing to inflammation that affects other systems.
The AAD recommends daily moisturizing, sun protection, and avoiding harsh soaps to maintain a healthy skin barrier. For people with chronic skin conditions, consistent treatment and regular follow-up with a dermatologist can help prevent flares and catch related health issues early.
National Healthy Skin Month runs throughout November and includes public education campaigns, free skin screenings at participating clinics, and resources for patients managing chronic skin conditions.
