Part 1: What It Is and Why So Many Women Have Never Heard of It
Many women enter midlife expecting to experience symptoms such as hot flashes or changes in sleep. These symptoms are widely discussed and commonly associated with menopause.
Far fewer women are warned about another set of changes that can occur in the same transition, those affecting the vagina, vulva, bladder, and surrounding pelvic tissues.
These changes are collectively known as Genitourinary Syndrome of Menopause (GSM).
Despite being extremely common, GSM remains one of the least discussed aspects of menopause.
What Is Genitourinary Syndrome of Menopause?
Genitourinary Syndrome of Menopause refers to a group of symptoms affecting the vaginal and urinary systems that arise as estrogen levels decline during the menopause transition.
The term GSM was introduced in 2014 by the International Society for the Study of Women’s Sexual Health and the North American Menopause Society to replace older terms such as vaginal atrophy.
The new terminology reflects a more accurate understanding that these changes affect multiple tissues and systems, not just the vagina.
GSM can involve the:
• vagina
• vulva
• bladder
• urethra
• pelvic floor tissues
Because these structures share common hormonal influences, symptoms often appear across both the reproductive and urinary systems.
How Common Is GSM?
Genitourinary Syndrome of Menopause is extremely common.
Research suggests that 27% to 84% of postmenopausal women experience symptoms associated with GSM.
The prevalence increases with time since menopause. Studies estimate that approximately 65% of women experience symptoms within the first year after menopause, rising to over 80% several years later.
Despite this high prevalence, many women never seek medical advice.
Estimates suggest that only about one quarter of women discuss these symptoms with a healthcare professional, and fewer than 10% pursue treatment.
For many women, embarrassment, lack of awareness, or the assumption that these changes are simply a normal part of aging prevent them from seeking support.
Why Many Women Have Never Heard the Term
Part of the reason GSM remains underrecognized is historical.
For many years, these symptoms were described using terms such as vaginal atrophy, which focused narrowly on structural tissue changes.
However, research has shown that declining estrogen affects multiple interconnected systems, including:
• vaginal tissues
• bladder and urethral tissues
• the vaginal microbiome
• pelvic floor muscle function
• local blood circulation
The term Genitourinary Syndrome of Menopause better reflects the broader physiological changes that occur during this stage of life.
Common Symptoms of GSM
The symptoms associated with GSM can vary widely between individuals. Some women notice only mild changes, while others experience more persistent symptoms.
Common symptoms include:
• vaginal dryness
• irritation or burning
• discomfort or pain with intercourse
• urinary urgency or frequency
• recurrent urinary tract infections
• decreased lubrication
Because these symptoms affect areas of the body that are not always openly discussed, many women assume they are simply something they must tolerate.
In reality, these changes reflect a biological response to declining estrogen.
A Different Kind of Menopause Symptom
It is important to understand that GSM behaves differently from some other menopause symptoms.
Symptoms such as hot flashes and night sweats often improve over time as the body adapts to shifting hormone levels.
GSM symptoms, however, reflect changes in the health and structure of estrogen-sensitive tissues.
Because estrogen levels remain low after menopause, these tissue changes typically do not resolve on their own and may gradually worsen without support.
Understanding this distinction helps women recognize why these symptoms deserve attention rather than dismissal.
Why Awareness Matters
Many women experience GSM symptoms without realizing they are related to menopause.
Without a clear explanation of the underlying physiology, it is easy to assume something is wrong with the body or that these changes are simply part of aging.
Increasing awareness of GSM helps women recognize that these symptoms are common, biologically driven, and treatable.
Coming Next in the Series
In Part 2 of this series, we’ll take a deeper look at why genitourinary changes occur during menopause, exploring the physiology of estrogen-sensitive tissues and how hormonal changes influence the vaginal microbiome, tissue structure, and bladder function.
Understanding the mechanisms behind these changes can help remove confusion and provide a clearer framework for supporting midlife health.
