Mouth Sores can arise from 4 documented medical conditions. Understanding the clinical context helps identify urgent causes early.
Systemic Lupus Erythematosus (SLE)
SLE is a chronic autoimmune disease that can affect multiple organ systems including the skin, joints, kidneys, and nervous system. The characteristic butterfly rash, joint pain, and kidney disease are hallmarks; flares are managed with immunosuppressants.
Celiac Disease
Celiac disease is an autoimmune reaction to gluten that damages the small intestine villi, impairing nutrient absorption. Symptoms include diarrhea, bloating, weight loss, and fatigue; strict gluten-free diet is the only treatment.
Behçet's Disease
Behçet's disease is a systemic vasculitis causing recurrent oral ulcers, genital ulcers, uveitis, and skin lesions. It is more prevalent along the ancient Silk Road and is managed with immunosuppressive therapy.
Lichen Planus
Lichen planus is an inflammatory condition affecting skin, mucous membranes, and nails, causing intensely itchy, flat-topped, purple papules. Oral lichen planus can cause erosive lesions; topical and systemic corticosteroids are used for treatment.
