Menopause and Hormone Use Linked to Bladder Health and Lower Urinary Tract Symptoms

What's new

A study published in PubMed Central investigated the relationship between menopausal status, hormone use, and bladder health in a diverse group of U.S. women [1]. The findings suggest that as women transition through perimenopause and into postmenopause, they are more likely to experience a decline in bladder health and an increase in lower urinary tract symptoms (LUTS) [1]. Surprisingly, the study also found that hormone use among postmenopausal women was associated with worse bladder health, challenging some common assumptions [1].

The science behind it

The researchers collected data from 3,423 adult women across the United States between May 2022 and December 2023, utilizing validated questionnaires to assess bladder health and LUTS [1]. Of the participants, 3,126 provided information on their menopausal status and hormone use, categorizing them as premenopausal (1,226), perimenopausal (260), or postmenopausal (1,640) [1].

Multivariable linear and logistic regression models were employed to analyze the associations [1]. The study revealed that both perimenopausal and postmenopausal women consistently reported poorer scores across multiple bladder health scales (BHS) and bladder function indices (BFI) when compared to premenopausal women [1]. Specifically, perimenopausal women showed a significantly higher likelihood of experiencing urgency urinary incontinence (UUI) and other LUTS, with an odds ratio of 2.27 for UUI compared to premenopausal women [1].

Regarding hormone use, the study observed that premenopausal women reported using hormones more frequently (38.3%) than perimenopausal (21.5%) or postmenopausal (13.2%) women [1]. Crucially, among postmenopausal women, hormone use was linked to a notable decrease in overall bladder health, with a 6.0-point lower BHS score and a 4.8-point lower BFI score compared to postmenopausal women not using hormones [1]. This suggests a complex interaction between hormonal changes, menopausal status, and bladder function.

What it means in practice

These findings underscore the importance of proactive bladder health management as women approach and navigate the menopausal transition [1]. Healthcare providers may need to increase awareness and screening for LUTS and declining bladder health in perimenopausal and postmenopausal women [1]. The association between hormone use and worse bladder health in postmenopausal women warrants further investigation to understand the underlying mechanisms and to inform clinical guidance [1]. It suggests that hormone therapy, while beneficial for some menopausal symptoms, might not universally improve or could even negatively impact bladder health in certain contexts [1]. This highlights the need for individualized assessments and discussions between patients and their doctors about the potential benefits and risks of hormone therapy, particularly concerning bladder function.

Caveats

This study is observational, meaning it can identify associations but cannot establish direct cause-and-effect relationships [1]. The data relied on self-reported questionnaires, which can be subject to recall bias [1]. Additionally, the study's definition of hormone use was broad and did not differentiate between types of hormones (e.g., estrogen, progesterone, or combination therapies), dosages, or routes of administration, which could have varying effects on bladder health [1]. The relatively low percentage of perimenopausal and postmenopausal women reporting hormone use might also limit the generalizability of findings related to hormone therapy [1]. Further research, including longitudinal studies and randomized controlled trials, is needed to confirm these findings and explore the specific impacts of different hormone regimens on bladder health across the menopausal spectrum.
