Understanding Perimenopause: Hormonal Chaos Before Menopause

Perimenopause is the transitional stage leading up to menopause, a phase every woman experiences, yet few fully understand until it’s upon them. It is more than just a warning sign of the final menstrual period; it’s a significant shift in hormonal balance that can influence every aspect of a woman’s body and mind.

Typically beginning in a woman’s forties, perimenopause can last anywhere from 1 to 10 years, with the average duration being about 4 to 6 years. It marks the beginning of the end of reproductive years and is often characterized by erratic estrogen fluctuations causing changes in  menstrual cycles and a wide range of physical and emotional symptoms.

What Exactly is Perimenopause?

As defined in a detailed article on the topic, “perimenopause refers to the phase prior to a woman’s final menstrual period, which commences when menstrual cycles start to vary in length by seven or more days, and includes the year after the final menstrual period.” This definition helps to highlight the unpredictability of the menstrual cycle during this time.

Hormonal fluctuations are at the core of perimenopause. “Leading up to menopause,” the article explains, “the normal rise and fall of the menstrual cycle becomes chaotic in perimenopause (for around 10 years).” This chaos is not just about periods becoming irregular, it is the result of hormone levels shifting erratically, especially estrogen and progesterone, which are critical to many bodily functions.

The impact of these changes is extensive because, as the article elaborates, “the receptors for these hormones are found throughout ‘every tissue of a woman’s body’ and therefore fluctuations and declines in these hormones can cause ‘widespread physical and mental impacts’.” This includes changes in mood, sleep patterns, metabolism, body temperature regulation, and even cognitive function.

Symptoms and Hormonal Interactions

Every woman experiences perimenopause differently. While some may sail through it with mild symptoms, others may find the changes overwhelming. Common symptoms include hot flashes, night sweats, irregular periods, fatigue, mood swings, and difficulty concentrating.

The article further explains that “during late-stage perimenopause and menopause, diminished oestrogen causes an increase in the levels of the hormones Follicle-stimulating Hormone (FSH) and Luteinising Hormone (LH).” These hormonal changes originate in the hypothalamus, a very important part of every one’s brain!

“The brain centre that secretes these hormones, the hypothalamus, directs many bodily functions, including body temperature, sleep patterns, metabolic rate, mood and reaction to stress,” the article continues, “so with higher levels of FSH and LH all these can be disturbed, including causing the very common hot flushes.”
