Introduction
Frequent oral ulcers may result from either hyperactive autoimmune responses or, more commonly, severe immune dysfunction. In addition, recurrent oral ulcers are often primarily caused by infections with certain bacteria, viruses, and other microorganisms. Patients with systemic diseases are prone to developing oral ulcers, mainly due to immune system impairment.
Oral and tongue ulcers are common mucosal disorders of the mouth, also known as stomatitis. They cause significant pain during active episodes but often resolve spontaneously without specific intervention. They are also referred to as recurrent aphthous ulcers. So, what causes frequent oral ulcers?
What Causes Recurrent Oral Ulcers?
Recurrent oral ulcers may result from either hyperactive autoimmune responses or, more commonly, severe immune dysfunction. In addition, infection by certain bacteria, viruses, or other microorganisms is likely a major contributing factor in recurrent cases. Patients with systemic diseases are particularly prone to developing oral ulcers—primarily due to underlying immune system impairment. Oral ulcers have been associated with gastric ulcers, duodenal ulcers, ulcerative colitis, Crohn’s disease (regional enteritis), and hepatitis. Research indicates that 30%–48% of individuals with recurrent oral ulcers also suffer from gastrointestinal symptoms such as abdominal distension, diarrhea, or constipation. Chronic sleep deprivation, poor sleep quality, and adverse environmental factors can also predispose individuals to oral ulcers. Deficiencies in trace elements—including zinc and iron—as well as folate and vitamin B12, are additional recognized risk factors.
Management strategies following onset of oral ulcers include maintaining optimal oral hygiene. When diagnosed with stomatitis, remember to clean your mouth thoroughly both morning and night. If possible, brush your teeth twice daily to prevent bacterial proliferation within the oral cavity. Additionally, avoid spicy foods that may irritate the ulcers. Maintain a positive mental attitude—even for minor illnesses—and ensure adequate, restorative sleep to support the body’s natural healing processes.
Therefore, it is essential to regulate your lifestyle rhythm and maintain nutritional balance. Vitamin deficiencies are sometimes the underlying cause of oral ulcers; thus, increasing intake of vegetables and other vitamin-rich foods is highly recommended. Furthermore, develop regular bowel habits—promptly responding to the urge to defecate. We hope this article has been helpful to you!
