Levonorgestrel intrauterine devices improve body constitution deviations in the perspective of traditional Chinese medicine and quality of life in patients with chronic pelvic pain and heavy menstrual bleeding.

Objective: This study aimed to investigate whether the use of levonorgestrel intrauterine devices (LNG-IUD) in the perspective of traditional Chinese medicine (TCM) can improve the body constitution deviations and quality of life (QoL) in patients with chronic pelvic pain (CPP) and heavy menstrual bleeding (HMB).

Materials And Methods: To understand the TCM body constitution differences between patients, patients with CPP from a gynecology clinic were first compared to a healthy control group from the Academia Sinica Taiwan Biobank (TWB). Patients with CPP were also compared with patients with pelvic diseases from the TWB. Patients with CPP and HMB, some who under LNG-IUD treatment, underwent tests for physical consistency. After 6-8 months, the TCM body constitution and QoL of patients who received LNG-IUD treatment were reanalyzed. The questionnaires used included the Self-Assessment Chart of Menstrual Bleeding, the Taiwanese version of the Pictorial Blood Loss Assessment Chart, the TCM Body Constitution Questionnaire, the 6-point Behavior Rating Scale, and the Taiwanese version of the Short Form-36 Health Survey. All data were analyzed using Wilcoxon's signed-rank test in SAS 9.4 software.

Results: In total, 2932 healthy women and 724 women with pelvic diseases were present in the TWB project. Moreover, 376 patients with CPP were admitted to a gynecology clinic, of whom 42 received LNG-IUD treatment. After LNG-IUD treatment, the primary endpoint was regarded as an improvement in Yang-Xu (lack of energy), Yin-Xu (lack of material), and phlegm stasis (accumulation of pathological products). These findings indicated an improvement in menstrual blood loss, pelvic pain, physical functioning, physical problems, body pain, general health, and emotional problems (p < 0.05).

Conclusion: LNG-IUD treatment improves body constitution deviations in TCM and QoL in patients with CPP and HMB. Our results provide a valuable reference for the use of modern medicine and TCM in treating CPP and HMB.
