Everything You Should Know About Menopause
Menopause occurs when a woman hasn’t menstruated in 12 consecutive months and can no longer become pregnant naturally. It usually begins between the ages of 45 and 55, but can develop before or after this age range.
Menopause can cause uncomfortable symptoms, such as hot flashes and weight gain. For most women, medical treatment isn’t needed for menopause.
Read on to learn what you need to know about menopause.

What are the symptoms of menopause?
Every woman’s menopause experience is unique. Symptoms are usually more severe when menopause occurs suddenly or over a shorter period of time.
Conditions that impact the health of the ovary, like cancer or hysterectomy, or certain lifestyle choices, like smoking, tend to increase the severity and duration of symptoms.
Aside from menstruation changes, the symptoms of perimenopause, menopause, and postmenopause are generally the same. The most common early signs of perimenopause are:
- less frequent menstruation
- heavier or lighter periods than you normally experience
- vasomotor symptoms, including hot flashes, night sweats, and flushing
Why does menopause occur?
Menopause is a natural process that occurs as the ovaries age and produce less reproductive hormones.
The body begins to undergo several changes in response to lower levels of:
- estrogen
- progesterone
- testosterone
- follicle-stimulating hormone (FSH)
- luteinizing hormone (LH)
One of the most notable changes is the loss of active ovarian follicles. Ovarian follicles are the structures that produce and release eggs from the ovary wall, allowing menstruation and fertility.
Most women first notice the frequency of their period becoming less consistent, as the flow becomes heavier and longer. This usually occurs at some point in the mid-to-late 40s. By the age of 52, most U.S. women have undergone menopause.
In some cases, menopause is induced, or caused by injury or surgical removal of the ovaries and related pelvic structures.
Common causes of induced menopause include:
- bilateral oophorectomy, or surgical removal of the ovaries
- ovarian ablation, or the shutdown of ovary function, which may be done by hormone therapy, surgery, or radiotherapy techniques in women with estrogen receptor-positive tumors
- pelvic radiation
- pelvic injuries that severely damage or destroy the ovaries
