Other Causes of Menopause
When Menopause Comes Early or Unexpectedly
While most women enter menopause naturally between 45 and 55, some experience it much earlier—either due to medical treatment, surgery, or underlying conditions. These are known as induced, premature, or secondary causes of menopause.
These situations often bring on symptoms more suddenly and can be more intense than the gradual transition of natural menopause. At The Menopause Association, we provide specialized guidance for women navigating these complex scenarios.
Surgical Menopause
The surgical removal of the ovaries causes immediate menopause, regardless of age. This is often done during a hysterectomy or as a preventive measure for women at high genetic risk of ovarian cancer.
What to expect:
- Sudden onset of hot flashes, mood changes, and sleep disruption
- Increased risk of bone loss and heart disease due to abrupt estrogen loss
Strong consideration for early hormone replacement therapy
Chemotherapy and Radiation
Cancer treatments can damage ovarian function, leading to early menopause. This can be temporary or permanent, and symptoms may start during or after treatment.
Women in this situation often need support for both physical and emotional symptoms, including help with fertility questions, vaginal dryness, and fatigue (link to physical and emotional symptoms).
Premature Ovarian Insufficiency (POI)
POI refers to menopause that occurs before age 40 without a clear medical trigger. It may be caused by autoimmune conditions, genetic factors, or unknown reasons.
Symptoms mimic perimenopause but appear earlier than expected. POI increases the need for monitoring and early preventive care due to longer-term risks associated with low estrogen.
Women with POI are often candidates for hormone therapy to protect bone and heart health well into their 40s and 50s.
Menopause After Hysterectomy (Uterus Removed, Ovaries Intact)
If only the uterus is removed, periods stop, but menopause still occurs naturally once the ovaries stop functioning. Without periods as a signpost, some women are surprised by brain fog, hot flashes, or low libido later on.
Tracking other symptoms and considering hormonal testing can help determine where you are in the transition.
You Deserve a Personalized Approach
