Hot flashes, brain fog, weight gain, and issues with sleep are all symptoms women may experience in midlife. Here we’ll break down their potential causes, looking at whether they’re impacted by fluctuating hormone levels commonly experienced during the menopause transition, or if they’re due to the natural process of aging; spoiler alert, in most instances both things are at play.¹

Aging and Hormones: What’s the Relationship?

While menopause is a natural part of aging, it can’t immediately explain all the physical changes you may experience in your 40s and 50s. Some symptoms, like irregular periods and hot flashes , are considered hallmark symptoms of perimenopause and menopause, respectively. With other symptoms, like sleeplessness and changes in cognition, the root cause may be completely unrelated to your hormones – making it more difficult to understand and manage these disruptions.

Menopause vs. Aging: Symptom Breakdown

A woman is considered to be in menopause once she has gone a complete 12 months without a period; aging, on the other hand, is considered to be a gradual, lifelong process.² The two life stages often occur simultaneously, making it difficult to pinpoint what’s causing certain changes in our health and wellness.

Here we’ll outline a few symptoms and physical changes often associated with aging and/or menopause and explain if they originate as symptoms of menopause, are due to natural aging, or are an effect of both.^{3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19}

Symptom	What It Is	Menopause	Aging
Vasomotor symptoms	Hot flashes and night sweats may cause sudden, intense periods of warmth and sweating.	Yes. Hormonal fluctuations starting during perimenopause affect areas of the brain that regulate body temperature.	No. Aging itself doesn’t directly cause hot flashes or night sweats, though they may occur due to other medical reasons related to age.
Irregular periods	Periods may be lighter, heavier, longer, shorter, or less predictable. You may also skip some periods.	Yes. As ovulation shifts, becoming irregular or ending completely, hormones change which impacts periods.	No. Aging itself doesn’t directly cause irregular periods, though perimenopause typically occurs in midlife (40s–50s).
Vaginal dryness	Vaginal tissue may become drier, thinner, and less elastic, causing irritation or pain during sex.	Yes. Declining estrogen levels may lead to genitourinary symptoms such as vaginal dryness, itching, irritation, and pain during sex.	No. Aging does not directly cause vaginal dryness but it could be a risk in those with underlying medical or surgical conditions.
Sleep changes	Sleep changes refer to difficulties falling or staying asleep or not getting enough restful sleep.	Yes. Menopause symptoms such as night sweats, mood changes, and sleeplessness may contribute to problems sleeping.	Yes. Sleep patterns may change with age, making it more difficult to fall or stay asleep.
Mood changes	Mood changes may refer to feelings of irritability, rage, and sadness as well as mental health issues such as anxiety or depression.	Yes. Per ACOG, around 4 in 10 women experience mood shifts during perimenopause that are similar to hormone-driven premenstrual syndrome symptoms.	Yes. Many variables cause mood changes with age, including stress, medical conditions, mobility limitations, sleep problems, loneliness, and brain disorders such as stroke, cancer, or dementia.
Cognitive decline	Cognitive decline includes brain fog, trouble focusing, and memory problems.	Yes. Studies show many women in perimenopause report symptoms of cognitive decline, likely due to changing hormones, sleep disruption, and other menopause symptoms.	Yes. Cognitive decline may occur over time as the brain ages.
Weight gain	Changes may include gaining fat, losing muscle, or storing fat differently.	Yes. Declining estrogen levels may slow metabolism and affect where the body stores fat, most notably increasing storage around the belly.	Yes. Aging slows metabolism, which may cause weight gain and muscle loss.
Bone loss	Bones gradually lose density and strength, increasing risks for osteoporosis.	Yes. A drop in estrogen may accelerate bone loss during perimenopause and menopause.	Yes. Bone loss continues with age.
Heart health changes	Cardiovascular changes include high cholesterol, high blood pressure, and increased risks for heart disease and stroke.	Yes. Declining estrogen may contribute to changes in cholesterol, blood pressure, and other heart health risks during and after menopause.	Yes. Cardiovascular risk increases with age.

Talk With Your Healthcare Provider About Normal Aging vs. Menopause Symptoms

Menopause is a natural part of aging, but that doesn’t mean you need to accept discomfort or assume every new symptom is due to shifting hormones in midlife. Be sure to talk with a healthcare professional about what you’re experiencing to help determine potential causes and gain advice on whether any of your symptoms warrant management or further evaluation.
