Objective: This study aimed to evaluate the effectiveness of comprehensive Korean medicine treatments, including Banhabaekchulchunma-tang, acupuncture, and chuna therapy, in managing functional dyspepsia in a patient with cervical disc herniation. Given the connection between cervical spine disorders and gastrointestinal dysfunction, this study also explored the importance of addressing cervical disc herniation to achieve optimal outcomes in treating functional dyspepsia. Methods: A hospitalized patient presenting with functional dyspepsia and cervical disc herniation received comprehensive Korean medicine treatments, including herbal medicine (Banhabaekchulchunma-tang), acupuncture, and chuna therapy. The treatments aimed at improving gastrointestinal symptoms while addressing the underlying cervical spine pathology. The effectiveness of these treatments on functional dyspepsia was assessed using the gastrointestinal symptom score (GIS), while cervical pain and overall health status were evaluated using the numerical rating scale (NRS) and the EuroQoL 5 dimensions (EQ-5D). Results: After integrated treatments targeting both cervical disc herniation and functional dyspepsia, the patient's NRS and EQ-5D scores showed significant improvement. Changes in GIS scores indicated relief of functional dyspepsia symptoms, while the treatment of cervical spine pathology also contributed to improved gastrointestinal function and overall well-being. Conclusion: This case study suggests that comprehensive Korean medicine treatments, including Banhabaekchulchunma-tang, acupuncture, and chuna therapy, may be effective in treating functional dyspepsia, particularly in patients with cervical disc herniation. The findings indicate that while addressing gastrointestinal dysfunction is crucial, considering the treatment of cervical spine disorders may also be beneficial, highlighting the potential value of an integrated therapeutic approach.
