Does Ozempic make you break up with your boyfriend? The social media theory about the GLP-1 divorce There’s still a lot of confusion surrounding the drug and love

You start taking a GLP-1 drug, lose weight, lose the food noise, lose interest in aperitivo, and at some point you look at your significant other and think: “Why is this person still in my living room?” It’s not exactly the side effect listed in the leaflet, but it’s one of the new theories making the rounds on TikTok, Reddit, and everywhere in between. It’s called Ozempic divorce. People are sharing stories about leaving their partners after starting Ozempic, Mounjaro, or other GLP-1 drugs. Not because the injection whispered leave him in their ear, but because something about the way they relate to themselves, desire, and what they were willing to tolerate from other people seems to have changed. One woman told Dazed that she decided to leave her husband a few weeks after starting treatment with tirzepatide. She had already been thinking about leaving, but credits the drug with contributing to her newfound self-esteem and ability to set boundaries. Meanwhile, online, another woman wrote “I filed for divorce after three weeks on Ozempic. I didn’t even suffer” under a video about post-Ozempic breakups, collecting likes and giving the internet its latest romantic plot twist.

Has your boyfriend become the new food noise?

GLP-1s seem to affect desire itself. Not just the desire to eat. People taking semaglutide or tirzepatide often say that their food noise, the persistent, almost automatic stream of thoughts about food, gets turned down. The cake is still good; you just don’t think about it while working, watching a series, or sitting on a call. And if the brain stops chasing a reward with the same intensity, it’s natural to wonder what happens to the others. Alcohol, compulsive shopping, video games, sex, hobbies: on forums, people have started sharing stories about losing interest in these activities too. In a Reddit thread from January 2026, one user said they had gradually lost interest in the gym, hiking, and cycling while simultaneously becoming much more intolerant of a stagnant relationship, to the point of wondering whether they were finally seeing the relationship for what it was — or whether the drug was changing the way they experienced pleasure. And so comes the million-dollar question, or at least the question worth one dose of semaglutide: “If it changes what you desire, can it also change who you desire?” Other people, however, said they had noticed just one thing: they no longer thought about food constantly. In other words, there is no universal romantic revolution. Just one giant it depends. Science doesn’t have a definitive answer yet. Some research is looking at the relationship between GLP-1s, the reward system, dopamine, and compulsive behaviours, but evidence on effects on relationships and sexuality is still limited and mixed. A 2025 Kinsey Institute study, for example, found that 18% of respondents reported increased sexual desire while taking GLP-1s, while 16% reported a decrease. A 2025 analysis of FDA data, meanwhile, identified 185 reports of sexual dysfunction. Translation? There is still no romantic version of the drug leaflet saying “may cause a sudden urge to dump Matteo.”

No, Ozempic isn’t making you dump your boyfriend

Ozempic is not couples therapy, it’s not a truth serum, and, most importantly, it doesn’t contain a tiny inner voice that tells you to move out once it’s injected. There is no evidence that GLP-1 drugs cause romantic breakups. But they can change quite a few things around a relationship. Your body changes. Your habits change. Your self-esteem can change. And, above all, the way you experience pleasure can change. If, for years, your relationship has also been built around Friday-night pizza, wine on the sofa, Sunday brunch, and “shall we get something to eat?” as the official language of communication, taking food out of the centre of the scene also means rewriting part of your life as a couple. Dr Niamh Martin explains to Dazed that eating and drinking are social rituals, and if they suddenly become less rewarding, they can also change the way someone experiences their relationship with their partner. Then there’s the question of what happens when you start liking yourself more. Losing weight can mean feeling more comfortable in your body, having more energy, and receiving different kinds of attention. And along with that new attention can come a question you might not have previously dared to ask: “But what am I doing here?” That doesn’t mean the drug created the problem. It may simply have made it harder to ignore. There’s a difference between causing a breakup and removing something that had been acting as glue for years. A 2018 Swedish study on bariatric surgery also observed changes in relationship status following significant weight loss, but a separation remains the result of many different factors. After all, relationships rarely end because one thing went wrong. Usually, there’s a whole condominium meeting of problems.

What if it isn’t falling out of love, but anhedonia?

Alongside people who say they finally felt free to leave unsatisfying relationships, there are others on social media talking about anhedonia, meaning a reduced ability to experience pleasure or interest. Not just in food. In friends. Sex. The gym. Work. That series that kept you awake until 2 a.m. the week before. On social media, this feeling of emotional flattening, of living life with the volume turned down, has been dubbed Ozempic personality. The distinction between wanting and liking can help explain why the issue is so complicated. As Il Post has noted, neuroscientist Kent Berridge has spent years studying the difference between wanting something and experiencing pleasure when we finally get it. GLP-1s are also being studied for their possible role in the brain circuits involved in desire and reward-seeking. This has led to the hypothesis that if the drive to seek gratification decreases, some people may perceive changes in other areas of their lives too. A review published in Nature Mental Health in 2025 suggested that the same mechanism capable of reducing certain compulsive behaviours could, in some people, contribute to anhedonia. But hypothesis is the key word here. So no, it doesn’t necessarily mean that once you start Ozempic, you’ll look at your boyfriend the way you look at a carbonara at 11:47 p.m. when you’ve already taken tirzepatide. You might lose interest in the second glass of wine. You might feel more confident. You might change your routine. You might simply realise that a relationship that worked perfectly when everything else in your life was working too is no longer enough for you. Or you might notice absolutely nothing, except that the pizza you would once have finished now leaves you happily with three slices on your plate. GLP-1s may change your relationship with desire; turning that automatically into a breakup button, however, is mostly an internet theory.
