"Ozempic Divorce" Is a Real Phrase. The Divorce Data Behind It Isn't About Ozempic.

"Ozempic divorce" has become one of those phrases that sounds like a diagnosis. Fox News ran a version of it in April. PureWow ran another, with a psychologist attached. Marriage and family therapists have built content calendars around it. The number doing the work — patients on GLP-1 drugs are roughly twice as likely to divorce — gets repeated with enough confidence that it reads as established fact. It isn't. No peer-reviewed study has followed a group of GLP-1 users long enough, or in large enough numbers, to measure their divorce rate against anyone else's. The number everyone is quoting comes from a different intervention entirely: bariatric surgery.

Fox News's April 10 piece, "Divorce boom may follow use of Ozempic and other GLP-1 drugs, experts warn," opens with the bariatric-surgery divorce statistic and folds it directly into a headline about GLP-1 drugs. PureWow's "Can Ozempic Lead to Divorce?", published in January 2025, quotes Rachel Goldman, a clinical psychologist and clinical assistant professor at NYU Grossman School of Medicine, who says of the surgery-linked pattern, "Yes, and it's nothing new. We've seen it post-bariatric surgery" — then adds that she's "seeing a similar increase" among patients on GLP-1s, an observation from her own practice rather than a study. A marriage and family therapist writing on her own coaching site puts it more flatly still, describing the lead researcher on the bariatric-surgery data as having "been explicit that similar mechanisms are likely to occur with GLP-1 receptor agonists such as Ozempic and Mounjaro." That researcher is real. He did talk to Fox News about GLP-1 drugs. That is not, however, what he told them.

The 2018 study everyone is citing is real, peer-reviewed, and genuinely striking on its own terms. Gustaf Bruze and colleagues published two Swedish cohorts in JAMA Surgery. The first followed 1,958 bariatric-surgery patients against 1,912 matched 'obese' controls for a median of ten years: among the 2,871 who were married or partnered at baseline, surgery patients divorced or separated at an adjusted hazard ratio of 1.28 (95% CI, 1.03–1.60; P=.03) compared with controls — a 10-year cumulative incidence of 17.1 percent versus 11.6 percent. The second cohort, drawn from Sweden's national surgery registry, compared 29,234 gastric-bypass patients with 283,748 general-population comparators over a median of 2.9 years: among those married at baseline, the adjusted divorce hazard ratio was 1.41 (95% CI, 1.33–1.49; P<.001), a 4-year cumulative incidence of 14.4 percent versus 8.2 percent. Both are observational cohorts, not randomized trials — they establish association, not causation, and the authors themselves note that ending an unhealthy relationship is not automatically an adverse outcome.

A second, independent US study reached a similar order of magnitude. Wendy King and colleagues at the University of Pittsburgh followed 1,441 patients who had gastric bypass or sleeve gastrectomy between 2006 and 2009, tracking marital status annually for five years. Among the 827 who were married going in, 8 percent had divorced and another 5 percent had separated without divorcing by year five, against a five-year divorce rate of roughly 3.5 percent in the general US population. What gets left out of nearly every "Ozempic divorce" piece is the other half of both studies: among the 999 single participants in the Swedish cohort, marriage or a new relationship occurred at a 10-year cumulative rate of 34.8 percent, against 19.4 percent for controls — a wider gap than the divorce finding. King's cohort showed the same shape: 18 percent of the 614 unmarried patients married within five years, against roughly 7 percent of unmarried US adults generally. Surgical weight loss is associated with more new relationships forming than existing ones ending, in both papers. The framing that survives online is the half that's louder. The "similar mechanisms" claim traces back to Per-Arne Svensson, a researcher at the University of Gothenburg's Sahlgrenska Academy and one of the Bruze et al. study's own co-authors. Here is what he actually told Fox News:

That is a hypothesis about weight-loss magnitude eventually converging between surgery and medication — not a claim that GLP-1 drugs will produce the same divorce numbers. The word "mechanisms" does not appear anywhere in the Fox News piece; the coaching site's paraphrase is a stronger claim than the reporting it says it's summarizing.

No peer-reviewed cohort study has tracked divorce or relationship dissolution specifically among GLP-1 users, in the published medical literature as of this writing. One unreviewed working paper has: Harvard economist Rebecca Diamond's NBER paper, circulated in June 2026, followed 242 women who had started a GLP-1 against 850 matched women who wanted the drug but hadn't started yet, using quarterly panel data from the Understanding America Study. Among the women who were already partnered when they started, it found no measurable rise in breakups — a 0.0-percentage-point change, with a margin of error of 1.7 points. Single women in the same data married or moved in with a partner at rates 18 to 29 percentage points higher than before starting, a shape closer to the bariatric cohorts' new-relationship finding than to their divorce one. It's one study, on 242 women, not yet reviewed by other researchers — nowhere near enough to settle anything on its own. But it is the only research that has looked directly at GLP-1 users' relationships, and what it found runs the opposite direction of the divorce headlines. Until a peer-reviewed cohort exists, the number attached to Ozempic remains a number about surgery, dressed up. The reader this matters to is the one on a GLP-1 prescription who has been told, by osmosis, that her marriage is now statistically at risk — using a study that never enrolled anyone taking her drug.
