Weight Gain

Is there an association between hormone therapy (HT) and weight gain?

In Hormone Replacement Therapy (HRT): Side Effects of Hormone Replacement Therapy (HRT) – Weight Gain and HRT the (United Kingdom) NHS note:

“There’s little evidence that most types of HRT make you put on weight.

You may gain some weight during the menopause and as you get older, but this often happens whether you take HRT or not”.2

In Maintaining Your Weight and Health During and After Menopause: Main Points – Lifestyle Choices and Ageing Are the Main Cause of Weight Gain After Menopause, dated 05 September 2025, the Australasian Menopause Society (AMS) include:

“It is a myth that Menopausal Hormone Therapy (MHT) causes weight gain, although some women might experience some fluid retention. On the contrary, MHT can decrease the accumulation of abdominal fat after menopause. The good news is that making healthy lifestyle choices can help you to achieve and/or maintain a healthy weight and improve your future health. Healthy choices help at any age, but are even more important around the time of menopause”.3

Other Causes

If HT does not cause weight gain, what may?

In 9 Myths and Misunderstandings About Menopausal Hormone Therapy (MHT): 1. Misunderstanding – MHT Will Make You Put on Weight, dated 05 September 2025, the AMS explain:

“Women who use MHT do not gain any more weight than women who do not use MHT. Ageing, social, lifestyle and medical factors are the main causes of midlife weight gain. The hormonal changes of menopause do cause fat to move from the hips to the abdomen”.4

Lifestyle Choices

Can lifestyle choices help with a healthy weight?

The AMS encourage us to make healthy lifestyle choices:

“The good news is that making healthy lifestyle choices can help you to achieve and/or maintain a healthy weight and improve your future health. Healthy choices help at any age, but are even more important around the time of menopause”.5
