Summary:
- Menopause is the cessation of menstrual periods for 12 consecutive months due to declining ovarian function and estrogen levels, typically preceded by perimenopause.
- Aging reduces ovarian responsiveness to follicle-stimulating hormone (FSH), increasing FSH levels and decreasing estrogen. Early menopause (ages 40-45) affects 5% of women, while premature ovarian insufficiency occurs before age 40 in about 1%.
- Symptoms vary, with over 75% of women experiencing hot flashes and night sweats, along with genitourinary issues, sexual dysfunction, and sleep difficulties.
- Many experience mood swings, irritability, cognitive changes, and an average weight gain of 2.3 kg (5 lbs), often around the midsection.
Menopause occurs with declining ovarian function, resulting in lower estrogen levels and no menstrual periods for 12 months. This is typically preceded by perimenopause marked by hormonal fluctuations. Aging reduces the ovaries’ response to follicle-stimulating hormone (FSH), leading to increased FSH and decreased estrogen. Early menopause can arise from genetics or medical treatments, while some may face premature ovarian insufficiency before age 40.
Understanding menopause and perimenopause is crucial for women in this pivotal moment of their lives.
Understanding Menopause and the Perimenopausal Transition
Menopause occurs when ovarian function declines, leading to significantly lower estrogen levels and the absence of menstrual periods for 12 consecutive months. This phase is typically preceded by perimenopause, a transitional period marked by fluctuating hormone levels, irregular menstrual cycles, and symptoms commonly associated with menopause.
Cause of Menopause
As women age, the ovaries gradually become less responsive to follicle-stimulating hormone (FSH). This hormone is released by the brain and normally prompts the ovaries to produce estrogen and develop follicles for egg release.
In response to this decreased sensitivity, FSH levels rise, but over time, the ovaries reach a point where they no longer respond to FSH, ceasing both follicle production and significant estrogen contribution.
A Note About Earlier Menopause
Some individuals may experience early menopause due to factors like genetics, surgery, or treatments for other conditions, such as cancer. For instance, certain chemotherapy medications can induce menopause.
In some cases, however, menopause occurs earlier than expected without a clear reason.
- Early Menopause occurs when menopause takes place between the ages of 40 and 45, affecting about 5% of women.
- Premature Ovarian Insufficiency (POI) occurs when menopause begins before the age of 40, affecting about 1% of women.
Symptoms of Menopause
Managing menopause symptoms varies from person to person. While some may not need treatment, others may benefit from personalized options based on their symptoms, medical history, and family history.
Vasomotor Symptoms of Menopause (VMS)
Hot flashes and night sweats—sudden, intense sensations of heat—affect over 75% of women, with 20% experiencing severe symptoms that significantly impact daily life. Effective treatments are available for vasomotor symptoms of menopause (VMS).
Genitourinary Symptoms of Menopause (GSM)
A range of physical changes linked to estrogen deficiency can occur, including vulvovaginal dryness, burning, irritation, painful intercourse, and urinary symptoms such as urgency, painful urination, or recurrent urinary tract infections (UTIs). There are good treatments for GSM, and suggestions can be made for other symptoms of menopause as well.
Lower Libido
Over half of postmenopausal women experience sexual dysfunction, often influenced by a variety of factors.
Sleep Difficulties
Many individuals face challenges such as difficulty falling asleep, waking up frequently, and trouble returning to sleep. If night sweats are contributing to nighttime disturbances, several treatment options are available.
Changes in Mood and Cognition
Many individuals experience irritability and mood swings during menopause, which may be more pronounced for those with a history of postpartum depression. Additionally, cognitive changes, such as difficulty finding the right words, can occur during this time.
Weight Gain
Weight gain during menopause varies, averaging around 2.3 kg (5 lbs), and is often associated with aging and changes in activity levels. This weight is typically distributed around the midsection.
Understanding the Effects of Menopause
Menopause and the perimenopausal transition involve hormonal changes due to decreased ovarian function and lower estrogen levels. Early menopause can result from genetics, surgery, or medical treatments, while some women may face premature ovarian insufficiency before age 40. Symptoms can vary widely, including hot flashes, genitourinary issues, sexual dysfunction, and mood swings.
While not everyone requires treatment, effective options are available to manage these symptoms and enhance your quality of life during this transition.
