<p>Women with obesity and diabetes taking weight loss and diabetes drugs Mounjaro and Zepbound for over a year lost more weight than their male counterparts—but also experienced more nausea and vomiting, according to new research.</p>



<h2 class="wp-block-heading" id="h-key-facts">Key Facts</h2>



<p>Researchers from Eli Lilly who tracked weight changes for a group of 4,677 people with Type 2 diabetes and obesity found female participants lost up to 24.6% of their body weight during treatment, while males lost up to 18.1% of their body weight.</p>



<p>The participants—2,999 females and 1,678 males—were followed for between 72 and 88 weeks, according to research presented this week at the Annual Meeting of The European Association for the Study of Diabetes.</p>



<p>These participants took different doses of once weekly tirzepatide—the generic name for Eli Lilly’s Mounjaro and Zepbound—shots during this time period.</p>



<p>The researchers noted although safety levels were similar for both sexes, women experienced nausea and vomiting—two of the most common side effects of tirzepatide—at significantly higher rates than their male counterparts.</p>

<p>“More research is needed to understand the mechanism by which females may experience more weight reduction in these trials,” Dr. Luis-Emilio García-Pérez, lead author and associate vice president of the Diabetes Global Medical Affairs team for Eli Lilly, said in a statement. However, previous research suggests there may be several factors that play a role in the difference of weight loss between men and women who take tirzepatide and other GLP-1 drugs. The differences in hormones between the two sexes may be the reason women lose more weight, according to a 2022&nbsp;<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8950819/" rel="noreferrer noopener" target="_blank">study</a>. A&nbsp;<a href="https://www.sciencedirect.com/science/article/pii/S073510972407445X?via%3Dihub" rel="noreferrer noopener" target="_blank">study</a>&nbsp;published last month in the Journal of the American College of Cardiology found women with obesity and heart failure taking GLP-1s lost more weight than male participants, and suggested differences in metabolism may be the reason. “As a general rule, females have more fat in their bodies, and it is distributed in a different way, which may respond to the mechanisms of action of this medication better,” Dr. John Lowe, a gastroenterologist and physician at Restore Care,&nbsp;<a href="https://www.healthline.com/health-news/wegovy-more-weight-loss-women#Why-Wegovy-might-help-females-lose-more-weight" rel="noreferrer noopener" target="_blank">told</a>&nbsp;Healthline. Lowe went on to add women suffer different societal pressures than men when it comes to body image, so this factor could make women more likely to stick to lifestyle changes—like diet and exercise—while adhering to the drug.</p>



<h2 class="wp-block-heading" id="h-key-background">Key Background</h2>



<p>Glucagon-like peptide-1 (<a href="https://www.ncbi.nlm.nih.gov/books/NBK551568/" rel="noreferrer noopener" target="_blank">GLP-1</a>) receptor agonists are a class of drugs used to treat diabetes and weight loss by interacting with the hunger part of the brain to suppress the appetite, and lowering blood sugar and A1C. Two of the most popular GLP-1s are semaglutide (brand name&nbsp;<a href="https://www.forbes.com/sites/ariannajohnson/2022/12/26/what-to-know-about-ozempic/">Ozempic</a>, Wegovy and Rybelsus) and tirzepatide, but other drugs in this class include dulaglutide, exenatide, liraglutide and lixisenatide. Tirzepatide is a two-part medication, as it’s a GLP-1 and glucose-dependent insulinotropic polypeptide (<a href="https://my-bmi.co.uk/medical-therapy/what-are-gip-receptor-agonists/#:~:text=GIP%20receptor%20agonists%20work%20with,few%20benefits%20for%20certain%20patients." rel="noreferrer noopener" target="_blank">GIP</a>), which works with the GIP hormone in the brain to increase insulin production and control appetite.</p>

<p>9 million. That’s about how many prescriptions of Ozempic, Wegovy, Mounjaro and Zepbound were written in the fourth quarter of 2022, according to&nbsp;<a href="https://www.cnbc.com/2023/09/27/ozempic-wegovy-drug-prescriptions-hit-9-million.html" rel="noreferrer noopener" target="_blank">data</a>&nbsp;from CNBC.

Women Taking Mounjaro And Zepbound Lose More Weight Than Men, New Study Suggests: What To Know


<h2 class="wp-block-heading" id="h-topline">Topline</h2>



<p>New study results found weight loss and diabetes drugs Zepbound and Mounjaro may significantly cut the risk of diabetes in people with prediabetes and obesity, adding to the growing list of diseases researchers have found the drugs can prevent.</p>



<h2 class="wp-block-heading" id="h-key-facts">Key Facts</h2>



<p>Drug manufacturer Eli Lilly&nbsp;<a href="https://investor.lilly.com/news-releases/news-release-details/tirzepatide-reduced-risk-developing-type-2-diabetes-94-adults" rel="noreferrer noopener" target="_blank">announced</a>&nbsp;the results from a three-year study that found its drug tirzepatide slashed the risk of developing type 2 diabetes by 94% in adults with prediabetes who also are obese or overweight.</p>



<p>Tirzepatide is the active ingredient in Mounjaro, the company’s approved diabetes drug, and Zepbound, the company’s approved weight-loss drug.</p>



<p>The drug also caused participants to lose weight: Those taking the highest 15 mg dose lost an average of 23% of their body weight compared to the placebo group, which only lost 2.1%.</p>



<p>However, during a 17-week follow up period when participants stopped treatment, weight was regained, and there was “some increase in the progression to type 2 diabetes,” though they still had an 88% reduction in risk, according to Lilly.</p>



<p>The most commonly reported adverse events among the study group were mild to moderate gastrointestinal issues like diarrhea, nausea, vomiting and constipation.</p>



<h2 class="wp-block-heading" id="h-big-number">Big Number</h2>



<p>98 million. That’s about how many Americans have prediabetes, totaling around one in three adults in the U.S., according to&nbsp;<a href="https://www.cdc.gov/diabetes/communication-resources/1-in-3-americans.html#:~:text=Graphic%20text%3A%20About%2098%20million,classified%20as%20type%202%20diabetes." rel="noreferrer noopener" target="_blank">data</a>&nbsp;from the Centers for Disease Control and Prevention.</p>



<h2 class="wp-block-heading" id="h-what-is-prediabetes">What Is Prediabetes?</h2>



<p>People with prediabetes have higher than normal blood sugar levels, but they aren’t high enough to be considered type 2 diabetes. It’s&nbsp;<a href="https://www.mayoclinic.org/diseases-conditions/prediabetes/symptoms-causes/syc-20355278" rel="noreferrer noopener" target="_blank">caused</a>&nbsp;by insulin resistance—the same thing that causes type 2 diabetes—which can happen because of genetics, excess body fat, a diet high in processed foods, physical inactivity, chronic stress, lack of sleep, long-term steroid use and hormonal disorders like cushings disease. Although prediabetes is fairly common, most Americans (80%) don’t know they have it,&nbsp;<a href="https://my.clevelandclinic.org/health/diseases/21498-prediabetes" rel="noreferrer noopener" target="_blank">according</a>&nbsp;to the Cleveland Clinic. This is because prediabetes often doesn’t have any symptoms, though some people do experience symptoms like skin tags, eye changes and darkened skin around the armpits, back or neck. However, prediabetes is reversible through lifestyle changes like weight loss,&nbsp;<a href="https://www.yalemedicine.org/news/prediabetes" rel="noreferrer noopener" target="_blank">according</a>&nbsp;to Yale Medicine.</p>
