Kat Carter & Kim Carlos

Dr. Cathleen Brown, Medical Director at Winona, returned to The Plus SideZ Podcast to talk about a topic hosts Kat Carter and Kim Carlos know firsthand: how perimenopause can affect weight, body composition, and weight-loss progress, even for people already on a GLP-1 medication. Guest Kelly Miller also joins to share her own journey through undiagnosed perimenopause and HRT.

The conversation covers why cortisol and stress hormones drive stubborn midlife weight gain, how HRT and GLP-1 medications can work together, and a wide range of symptoms — from brain fog to genitourinary changes — that often go unrecognized. Dr. Brown also breaks down the difference between a hysterectomy and full ovarian removal, and how each affects a woman's hormone timeline.

About This Episode

Hosts Kat Carter and Kim Carlos open up about their own experiences with perimenopause disrupting years of hard-won progress on GLP-1 medications, describing sudden weight stalls, cravings, and mood changes that neither expected. Guest Kelly Miller shares her personal path to diagnosis, including major fatigue, brain fog, and the frustration of being offered birth control instead of real answers.

Dr. Brown ties it all together, explaining the cortisol-driven mechanism behind "meno belly," why HRT and GLP-1 medications can work synergistically for weight loss, and how symptoms like joint pain, TMJ, sleep apnea, and genitourinary changes are all connected to declining estrogen. She also addresses common misconceptions around hysterectomy, testosterone regulation, and where to find reliable, physician-reviewed information.

Key Takeaways

Perimenopause Can Stall GLP-1 Weight Loss Progress

Dr. Brown explains that rising cortisol during perimenopause puts the body into a stress response that can make weight management more challenging, even when someone is maintaining healthy nutrition, which is why some patients on GLP-1 medications hit unexplained “stalls” until their hormones are addressed.

HRT and GLP-1 Medications Can Work Together

Dr. Brown notes that combining hormone replacement therapy with a GLP-1 medication can be synergistic, often helping women lose more weight together than with a GLP-1 alone, especially once cortisol and sleep improve.

A Hysterectomy Doesn't Always Mean Menopause Has Started

Dr. Brown clarifies that removing the uterus alone (hysterectomy) doesn't stop ovarian hormone production, so women can still go through natural perimenopause and menopause later; only removing the ovaries (oophorectomy) causes immediate, surgical menopause.

Vaginal Estrogen Is an Option for Genitourinary Symptoms, Including for Some Breast Cancer Survivors

Dr. Brown explains that vaginal estrogen is only locally absorbed, making it a safe option for genitourinary symptoms even for women who aren't candidates for systemic HRT, including many breast cancer survivors.

Testosterone for Women Is Tightly Regulated and Often Requires In-Person Care

Because testosterone is a controlled substance and currently only FDA-approved for men, Dr. Brown explains that appropriately treating low testosterone in women often requires an in-person menopause specialist rather than telehealth.
