Weight changes during perimenopause: what should you discuss with your doctor?

Weight or body shape can change in midlife for more than one reason. Learn what is worth discussing with a doctor, and why hormones are not the only explanation.

Dr Nuwanthi Nandasiri

Some women notice their weight, clothes or body shape changing in midlife and wonder whether perimenopause explains it. Sometimes weight is the concern. Sometimes it is where the body is carrying fat, or a change in strength, even when the scales have barely moved.

This article is about that conversation. It does not list the wider symptoms of perimenopause or explain when bleeding needs urgent care. For that, read when should you see a doctor about menopause symptoms?.

Weight and body composition can both change in midlife

The Australasian Menopause Society describes an average gain of about half a kilogram a year between the ages of 45 and 55. That figure is an average across studies, not a prediction for you. (Australasian Menopause Society)

The same society notes that hormonal changes around menopause are associated with more body fat and less lean mass, and that fat may settle more around the abdomen than around the hips and thighs. Those composition changes can occur even when overall weight does not simply rise. (Australasian Menopause Society; Australasian Menopause Society)

Do not assume hormones are the whole explanation

Weight gain during and after menopause has more to do with lifestyle and ageing than with hormonal changes alone. Hormones are part of the picture, not an automatic cause of every change you notice. (Australasian Menopause Society)

Obesity is also shaped by environmental, social, biological and behavioural factors acting together. (World Health Organization) A similar change can have different contributors for different people, which is why a doctor looks at your situation rather than assigning one cause.

What might a clinician explore?

Lifestyle factors discussed around menopause include sleep, eating patterns and physical activity, along with smoking and alcohol. Sufficient sleep, a healthy diet and regular physical activity are among the strategies the Australasian Menopause Society describes for this stage of life. What suits you depends on your health and circumstances, and plans are meant to be individual. (Australasian Menopause Society; Australasian Menopause Society)

You can also mention medicines and supplements you take. This article does not identify which medicines affect weight. Raising them lets your doctor consider them with the rest of your history.

Other health issues can sit alongside midlife changes. Say what else is worrying you, rather than deciding in advance that hormones explain it.

Health goals can be broader than a number on the scales

Fat carried around the abdomen is associated with cardiovascular disease and diabetes, so health around menopause is not only about what the scales say. (Australasian Menopause Society) Overweight and obesity also contribute to other preventable chronic conditions, including some cancers. (Australian Institute of Health and Welfare)

You might care about energy, strength, sleep, mood, or how you move. Those are reasonable things to put on the agenda. Nothing in this article promises a particular weight, waist or symptom result.

When might an individual assessment help?

Menopause is described as a useful time to speak with a doctor, look at overall health and talk about lifestyle changes that fit you. (Australasian Menopause Society)

Consider a routine appointment if weight or body composition is bothering you, if changes are affecting daily life, or if you want those changes considered together with sleep, eating, activity or other symptoms.

For symptoms such as hot flushes, mood or bleeding, use when should you see a doctor about menopause symptoms?. This article does not replace that guidance.

Midlife weight changes are worth a conversation

A consultation can look at what has changed for you, including sleep, eating, activity and your wider health. No particular change in weight can be guaranteed.
