Hysterectomy is associated with postmenopausal body composition characteristics.

Area of Science:

• Gynecology
• Endocrinology
• Body Composition Analysis

Background:

• Hysterectomy is a common surgical procedure for women.
• The effects of hysterectomy without oophorectomy on long-term body composition and weight gain remain an area of interest.
• Understanding these effects is crucial for post-surgical patient care and management.

Purpose of the Study:

• To investigate the impact of hysterectomy without oophorectomy on body composition.
• To assess postmenopausal weight gain in women who have undergone hysterectomy compared to natural menopause.
• To explore potential contributing factors to observed changes.

Main Methods:

• Study included 184 Viennese females aged 47-57 years.
• Comparison between women who underwent hysterectomy (without oophorectomy) and those who experienced spontaneous menopause (controls).
• Assessment of body weight, fat tissue distribution (especially abdominal), and bone mass.

Main Results:

• Hysterectomized women were significantly heavier than control subjects.
• Increased fat tissue, particularly in the abdominal region, was observed in hysterectomized women.
• Women who had hysterectomies reported significantly greater weight gain since menopause (9.1 kg vs. 6.0 kg).
• No significant differences in bone mass were detected between groups.

Conclusions:

• Hysterectomy without oophorectomy is associated with increased body weight and abdominal adiposity.
• This surgical intervention may contribute to accelerated postmenopausal weight gain.
• Hormonal changes and psychological stress are discussed as potential underlying mechanisms.
