11 Silent Autoimmune Alarms Your Dermatologist Won't Catch

11. Non-Healing Mouth Sores or Ulcers

Occasional canker sores are common, but when sores inside the mouth become frequent, persistent, or slow to heal, your immune system may be reaching out for extra attention. Autoimmune conditions such as lupus, celiac disease, or Behçet’s can present with recurring ulcers or sores that don’t respond well to typical home remedies. These aren’t always visible to dermatologists and might also fly under the radar at dental or routine medical checkups.

Giving Yourself Permission to Seek More Answers

Experiencing any one of these symptoms doesn’t mean you have an autoimmune disease—life is full of surprises and unexplainable shifts. But when patterns form, and several of these gentle warnings appear without clear cause, it’s a sign your body wants to be heard. Letting yourself see these subtle alarms as acts of inner wisdom, not weakness, is a powerful act of self-care.
