Key takeaways:
Many women experience weight changes during perimenopause and menopause. Hormone changes, altered sleep, and lower activity levels can all contribute to weight gain.
Menopausal hormone therapy (MHT), previously called hormone replacement therapy (HRT), can help treat symptoms like hot flashes, night sweats, and vaginal dryness.
MHT may help with weight management when combined with diet changes and exercise.
Menopausal hormone therapy (MHT), formerly called hormone replacement therapy (HRT), is becoming more common for treating symptoms of perimenopause and menopause. Years ago, concerns about its safety led many people to stop using it. But newer research has shown that hormone therapy is safe and effective for many people.
Hormone therapy can help with symptoms like hot flashes and vaginal dryness. But can it also help with weight gain during menopause? Here’s what the research says about hormone therapy and weight loss after menopause.
Why causes weight gain during menopause?
Many people gain weight during menopause. This happens for several reasons:
Hormone changes: Levels of estrogen, progesterone, and testosterone begin to fall during perimenopause. These hormones help regulate how your body stores fat and builds muscle. As hormone levels change, you may gain more fat around your abdomen. You may also lose muscle mass. Because muscle burns more calories than fat, these changes can make it easier to gain weight over time.
Sleep changes: Hormone changes can cause hot flashes and night sweats that interrupt sleep. At the same time, your body makes less melatonin as you get older, which makes it harder to fall asleep and stay asleep. Poor sleep has been linked to weight gain because it can affect your appetite, energy levels, and food choices.
Stress and lifestyle changes: Menopause often happens during a busy stage of life. Many people are balancing work, family responsibilities, and caring for parents who are getting older, while also coping with mood changes related to shifting hormone levels. These stresses can leave less time and energy for regular exercise and healthy habits, which may make weight gain more likely.
Does HRT help with weight loss during menopause?
Menopausal hormone therapy isn’t approved by the FDA as a weight-loss treatment, and it doesn’t appear to cause significant weight loss on its own.
Studies suggest that hormone therapy doesn’t have much effect on overall body weight. But it may help reduce fat around your abdomen and improve how your body responds to insulin.
There’s also some evidence that MHT may help other weight-loss treatments work better. A recent study found that people in menopause who took MHT along with tirzepatide (Mounjaro, Zepbound) lost more weight than those who took tirzepatide alone. They also had similar or slightly better improvements in some markers of metabolic health.
How does HRT help with weight loss during menopause?
Researchers are still studying whether hormone therapy can help with weight loss during menopause. But there are a few ways it may make weight management easier.
Hormone therapy may improve how your body uses insulin and where it stores fat. Some studies also suggest it may help your body burn more fat for energy. But researchers are still learning how much these changes affect body weight.
Hormone therapy may also help in less direct ways. By reducing hot flashes and night sweats, it can improve sleep and help you feel more rested. Better sleep, fewer menopause symptoms, and improved mood may make it easier to stay active and keep up with healthy habits, like regular exercise.
What else can help with weight management during menopause?
Hormone therapy can be one part of a weight management plan during menopause. But it works best alongside healthy habits that support your metabolism, muscle mass, and overall health. Try these tips:
Limit alcohol. Alcohol adds extra calories and can make it harder to get good-quality sleep. Alcohol can also increase cortisol levels, which make it harder to regulate your weight.
Make sleep a priority. Aim for 7 to 9 hours of sleep each night. Poor sleep can increase your appetite, make you crave high-calorie foods, and leave you with less energy to be active.
Choose healthy foods. Eat plenty of lean protein, high-fiber foods, fruits, vegetables, and whole grains. Limiting processed foods and added sugars can also support a healthy weight.
Stay active. Regular exercise helps build and maintain muscle, reduce body fat, and support heart and bone health. Find activities you enjoy so it’s easier to stick with them over time.
Frequently asked questions
Menopausal hormone therapy (MHT) is a good option for many people who have bothersome menopause symptoms, especially if they’re younger than 60 or within 10 years of starting menopause. But hormone therapy isn’t right for everyone. People with a history of certain cancers, blood clots, stroke, heart disease, or liver disease may need to avoid it. Your healthcare team can help you decide if it’s right for you.
The average age of menopause in the United States is 52. But perimenopause starts several years earlier, often in your mid-to-late 40s. You may notice symptoms like hot flashes, irregular periods, and weight changes before your periods stop completely.
Some of the earliest signs of menopause are changes in menstruation. Periods may come at irregular intervals or be lighter or heavier than normal. Other early signs of menopause include vaginal dryness, decreased libido, and sleep changes.

The bottom line
Most people experience weight changes as a result of hormone shifts during menopause. Menopause hormone therapy (MHT) is FDA-approved for treating symptoms of menopause, like hot flashes and night sweats. MHT isn’t a weight-loss treatment. But it may help with weight management when combined with increased physical activity and a nutritious diet.
