Clinical Report: Hormonal and Ovarian Changes After Bariatric Surgery in Women

Overview

This prospective study evaluated 67 women with BMI ≥35 undergoing robotic bariatric surgery, assessing hormonal profiles and ovarian morphology preoperatively and at 3 and 6 months postoperatively. Significant improvements were observed in weight loss, androgen levels, ovarian morphology, and clinical symptoms related to reproductive health.

Background

Obesity disrupts hormonal balance in women of reproductive age, affecting ovarian and adrenal hormones critical for reproductive function. Bariatric surgery is an effective intervention for morbid obesity, promoting weight loss and metabolic improvements through multiple physiological mechanisms. Prior studies have shown bariatric surgery improves fertility, ovulatory function, and pregnancy outcomes by modulating hormonal profiles. However, detailed longitudinal data on hormonal and ovarian structural changes post-surgery remain limited.

Data Highlights

Key Findings

• Robotic Roux-en-Y gastric bypass was performed in 76.7% of patients; sleeve gastrectomy in 23.9%.
• Significant postoperative weight loss was associated with decreased androgen levels (total testosterone, androstenedione, DHEA-S).
• Ovarian morphology improved post-surgery, with reduction in polycystic ovary features on ultrasound.
• Clinical symptoms such as hirsutism and dysmenorrhea showed significant improvement by 6 months postoperatively.
• Hormonal changes included normalization of FSH, LH, and increased SHBG levels, indicating improved reproductive hormonal balance.
• Comorbidities such as diabetes and hypothyroidism were present in about one-third of patients, highlighting the complex metabolic profile of the cohort.

Clinical Implications

Bariatric surgery in women with morbid obesity leads to substantial improvements in hormonal profiles and ovarian morphology, which may enhance fertility and reduce symptoms of hyperandrogenism. Monitoring hormonal and ovarian changes postoperatively can guide clinicians in managing reproductive health and optimizing outcomes in this population.

Conclusion

This study demonstrates that bariatric surgery induces favorable hormonal and structural ovarian changes in women with obesity, supporting its role in improving reproductive health. Continued research is warranted to elucidate long-term effects and individual patient variability.
