The Connection Between HRT & GLP1 Weight Loss
Many menopausal women who have srtuggled to lose weight have found that GLP1 medications (like Ozempic and Wegovy) have helped them lose weight when nothing else has worked. Now, two recent studies from Mayo Clinic researchers suggest that women using hormone therapy may lose more weight on semaglutide, the active ingredient in Wegovy and Ozempic, than women who are not. The findings are early and observational, but they have sparked a great deal of interest among women who have struggled with midlife weight gain.
We are watching this research closely because it brings together two of the most common concerns women bring to us in midlife: bothersome menopause symptoms and stubborn weight gain.
The Difficulty of Menopause Weight Loss
Many women notice that their bodies begin to change in their forties and fifties, even when their eating and exercise habits have not. Clothes fit differently, and weight that once settled on the hips and thighs begins to collect around the waist. Familiar strategies that worked a decade earlier often stop producing results, which can be discouraging.
Several factors are at work. Aging itself gradually reduces muscle mass and slows metabolism, while sleep disruption, stress and changes in activity levels add to the challenge. Declining estrogen also appears to shift where the body stores fat, favoring the abdomen. No single hormone explains every change, which is why menopause weight loss usually calls for a broader approach than just willpower alone.
Long-term research supports this picture. The Study of Women’s Health Across the Nation, which has followed thousands of women through midlife, found that fat mass tends to rise and lean muscle tends to decline during the menopause transition, with the fastest changes occurring in the years surrounding a woman’s final period.
Researchers are now asking whether a woman’s reproductive stage, and whether she uses hormone therapy, might influence how her body responds to weight loss medications. That question matters because GLP1 drugs were largely studied in mixed groups of men and women, without close attention to menopause.
Top Dearborn Heights OBGYN Dr. Chadi Haddad evaluates menopause symptoms and weight concerns as separate issues that deserve their own assessments, even when they show up at the same time. This allows him to recommend HRT, weight management support or both based on what each woman truly needs.
Early HRT and GLP1 Research
The first study was on HRT and GLP1 medications was published in the journal Menopause in 2024. Mayo Clinic researchers reviewed the medical records of 106 postmenopausal women with overweight or obesity who had taken semaglutide for at least three months. Sixteen of them were using menopause hormone therapy, and 90 were not.
The women using HRT lost more weight at every checkpoint. After 12 months, they had lost an average of about 16 percent of their total body weight, compared with about 12 percent among women not using hormones. The difference held up after the researchers adjusted for other factors that might affect weight.
Still, this was a small study that looked back at existing records rather than randomly assigning women to add HRT. And the researchers noted that women who use HRT may differ in other ways, such as having better access to care or healthier daily habits. while the results looked promising, the authors called for larger studies to confirm the results.

Recent Evidence on HRT & GLP1 Weight Loss
A much larger study on this topic followed in October 2026. On October 20, The Menopause Society announced findings presented at its annual meeting in San Diego by Dr. Regina Castaneda of Mayo Clinic Florida. The research team reviewed records from nearly 2,400 women taking semaglutide (the active ingredient in Ozempic & Wegovy) and nearly 1,500 women taking tirzepatide (the active ingredient in Mounjaro and Zepbound). All of the women were older than 45 and had a body mass index above 27.
Among women taking semaglutide, HRT use was associated with significantly greater weight loss that was sustained over time. Women on tirzepatide who used hormone therapy also lost more weight early on, but by the end of the study the difference between the groups was no longer statistically significant. The researchers noted that the hormone therapy effect appeared stronger with semaglutide.

Why Does HRT Make Wegovy & Ozempic work Better?
Scientists have proposed one possible explanation. Laboratory and animal research suggests that estrogen and GLP1 signaling may work together in parts of the brain and body that regulate appetite and energy use. HRT may also ease hot flashes and night sweats, which can improve sleep and make it easier to stay active. These ideas remain theories, and the studies so far cannot establish whether HRT itself was responsible for the difference.
It is equally important to understand what these findings do not mean. GLP1 medications also work well without hormone therapy, and HRT is not required to benefit from Ozempic or Wegovy. The Menopause Society has stated clearly that weight loss alone is not a reason to prescribe menopause hormone therapy, and its 2022 position statement bases HRT decisions on symptoms, age, time since menopause and individual health risks.
At his Dearborn Heights practice Dr. Haddad only prescribes HRT only when it is medically appropriate for a woman’s symptoms and health history, never solely to boost GLP1 weight loss.

If you are dealing with menopause symptoms and weight gain at the same time, you deserve an evaluation that looks at both. Dr. Haddad will review your symptoms, weight history, lab work, current medications and personal goals before recommending a menopause plan.
Depending on your circumstances, the right choice may be HRT, a GLP1 medication, both or neither. Weight loss on HRT or a GLP1 medication tends to be gradual, and regular follow-up visits allow Dr. Haddad to monitor your progress, manage side effects and adjust treatment as needed. Eating enough protein, staying active and adding strength training help protect your muscle and keep your results lasting.
