Early & Premature Menopause

There isn't always an identifiable reason. Early or premature loss of ovarian function may be associated with:

• Genetics or chromosomal conditions 

• Autoimmune conditions 

• Surgery involving the ovaries 

• Chemotherapy or radiation therapy 

• Certain medical conditions or treatments 

Some women experience menopause naturally before age 45 without surgery or another obvious medical cause.

Family history may play a role, and having a mother or sister who experienced menopause early may increase the likelihood of an earlier menopause transition.

Some treatments intentionally or unintentionally reduce or stop ovarian function. Depending on the treatment, this may be temporary or permanent.

Because hormone levels can change more rapidly than they do during natural perimenopause, symptoms may also appear more suddenly.

Surgical menopause occurs when both ovaries are removed before natural menopause.

Unlike natural menopause, in which ovarian hormone production usually changes gradually, removal of both ovaries causes estrogen and other ovarian hormone levels to fall abruptly.

This can mean that symptoms begin quickly and may initially feel more intense. Because hormone levels fall abruptly, menopause symptoms may begin suddenly and can initially be more intense than symptoms that develop during a gradual natural menopause transition. 

Removal of the uterus alone does not necessarily cause surgical menopause if the ovaries remain, although menstrual periods will no longer occur.

Chemotherapy, radiation involving the ovaries or pelvis, and some hormone-related cancer treatments can affect ovarian function.

For some women, periods and ovarian function return after treatment. For others, the change is permanent. The likelihood depends on factors including age, treatment type and dose.

Women facing cancer treatment who may want children in the future should ideally have the opportunity to discuss fertility preservation before treatment begins, whenever circumstances allow.

Management of menopause symptoms after cancer can also be more complex, particularly with hormone-sensitive cancers, so treatment decisions should be individualized with the appropriate healthcare team.

Experiencing menopause considerably earlier than the average age means spending more years with lower levels of ovarian hormones.

That makes long-term health an especially important part of care.

Estrogen helps protect bone. Earlier estrogen loss can increase the risk of reduced bone density and osteoporosis over time.

Depending on your age, medical history and circumstances, your healthcare provider may discuss bone-density assessment as well as adequate calcium and vitamin D, weight-bearing and resistance exercise, smoking cessation, alcohol intake and other measures that support bone health.

Earlier menopause is also associated with increased cardiovascular risk. That doesn't mean cardiovascular disease is inevitable. Rather, it makes established heart-health measures particularly important, including:

• Regular physical activity 

• Not smoking 

• Maintaining healthy blood pressure 

• Managing cholesterol 

• Managing blood glucose 

• Following a balanced dietary pattern 

• Maintaining a healthy weight appropriate for you 

Regular preventive healthcare becomes particularly valuable when menopause occurs early.
