Perimenopause vs Menopause: Difference and Comparison

The reproductive life of a woman begins to culminate when she enters her forties or fifties. The entire spectrum of the process is normal as a woman comes to age, and there’s nothing to worry about.

However, there are quite a few symptoms that are found to be common before and after the period of culmination. The entire process of termination is divided into three stages – perimenopause, menopause, and post-menopause.

Key Takeaways

  1. Perimenopause is the transitional phase leading to menopause, characterized by hormonal fluctuations and irregular periods.
  2. Menopause marks the end of a woman’s reproductive years, defined by the absence of menstruation for 12 consecutive months.
  3. Symptoms during perimenopause can include hot flashes, mood swings, and sleep disturbances, while menopause relieves these symptoms.

Perimenopause vs Menopause

Perimenopause is the medical term that describes the stage in a woman that occurs before the start of menopause, and it happens in the early forties. Menopause is the medical term that describes the stage in a woman’s life when her menstruation cycle stops, and it occurs during old age.

Perimenopause vs Menopause

Perimenopause refers to the stage that occurs before the beginning of menopause. This happens when a woman enters her 40s.

However, some women may find perimenopausal symptoms surfacing as early as when they are 30. The term perimenopause can be translated to ‘around menopause’ and can also be referred to as ‘menopausal transition’.

Menopause is a natural biological process that occurs in women between the age of 45-50.

In the United States, most women experience this when they reach the age of 51! However, for all women, menopause marks the end of their reproductive life. The menopausal stage begins 12 months after a woman has stopped menstruating.

This period occurs years before the menopause period. Generally, a woman is in her 30s or 40s when she experiences this.

During perimenopause, the ovaries in a woman reduce the production of oestrogen over time. The average time when a woman experiences this is 4 years.

However, some women may even have it for a few months or even 10 years. When a woman does not get her menstrual period for a total of 12 months, the stage of perimenopause ends.

Some common symptoms that women experience during perimenopause include hot flashes, low sex drive, breast tenderness, fatigue, irregular periods, worsened premenstrual syndrome, vaginal dryness, urine leakage, urinary urgency, mood swings, trouble sleeping, etc.

Some women may even experience heavy periods or spotting after sex.

Women should get themselves checked by a medical professional whenever they experience these symptoms. A doctor diagnoses a woman with perimenopause based on these symptoms only.

A blood test to check hormone levels may also prove to be useful. Interestingly, a woman can get pregnant even while she experiences perimenopause.

There are many causes other than the age factor due to which menopause occurs in women. For example, chemotherapy and radiation can induce menopause and cause dire symptoms such as hot flashes and night sweats.

Another example is primary ovarian insufficiency. This is when the ovaries fail to produce a natural number of reproductive hormones.

It affects about 1% of women and causes them to experience menopause before the age of 40. This is also called premature menopause. For women who experience this, hormonal therapy is recommended.

  1. It’s quite worrisome that a woman in her 30s can start experiencing perimenopausal symptoms. This is not good.
