Do You Frequently Get Mouth Sores? Chronic Aphthous Stomatitis Might Be Due to This

Modern medicine describes recurrent mouth sores as recurrent aphthous stomatitis. While its precise cause remains under investigation, multiple contributing factors are recognized. These clinical findings correspond closely with the traditional concepts of heart fire and spleen-stomach dampness-heat. First, heart fire aligns closely with physiological stress responses. Under sustained stress, the hypothalamic-pituitary-adrenal axis triggers the release of stress hormones, including cortisol. While early hormonal responses can regulate immune activity, chronic activation destabilizes the immune system and promotes excessive inflammation. The oral mucosa is richly vascularized, densely populated with immune cells, and sensitive to environmental triggers; when immune regulation falters, minor irritation readily progresses into mucosal ulceration. Palpitations and disturbed sleep reflect an autonomic nervous system imbalance, which further contributes to decreased immunity and accelerated inflammatory activity. The concept of damp-heat in spleen and stomach reflects gastrointestinal health and nutritional status. Current medical research highlights the gut-brain axis, the bidirectional communication network connecting the digestive tract and central nervous system. Microbial imbalance in the gut, known as dysbiosis, can trigger a systemic inflammatory response that directly affects the oral mucosa. Furthermore, impaired spleen-stomach function mirrors compromised nutrient absorption. Individuals with chronic stomatitis frequently present with deficiencies in essential micronutrients, particularly the vitamin B complex (including vitamin B12 and folic acid), iron, and zinc. Because these nutrients are indispensable for mucosal epithelial repair and immune maintenance, their absence impairs tissue recovery and prolongs ulcer duration. Additional factors may trigger stomatitis, including sodium lauryl sulfate in toothpastes, dietary sensitivities to foods such as chocolate, coffee, and nuts, hormonal fluctuations, genetic susceptibility, and minor physical trauma. Recurrent mouth sores serve as a clear physiological indicator of chronic stress, nutritional imbalance, and decreased immunity, calling for closer attention to underlying physical health.
