The high-profile semaglutide medication Ozempic and Wegovy have modified how hundreds of thousands of adults handle kind 2 diabetes and weight, respectively. Now many 1000’s of youngsters are being prescribed semaglutide and related medication in its class, elevating questions on long-term penalties.
The medication, which average blood glucose ranges and create a way of satiety, or fullness, have been authorised for teenagers aged 12 and up particularly for weight reduction just some years in the past. Pediatricians are seeing putting well being modifications of their sufferers who’re receiving the remedy, and plenty of mother and father and their children are desirous to get the remedy.
However some specialists are uneasy concerning the pattern and flag a number of issues and uncertainties. The medication are at the moment thought-about a lifelong remedy, which could be a troublesome resolution for adults however much more daunting for youngsters. Pediatricians and researchers have additionally known as for long-term research to deal with worries concerning the medication’ results on restrictive consuming habits, bone energy, puberty and development. This lack of longitudinal knowledge provides well being practitioners pause about teenagers’ future well being.

Weight and Well being
The connection between weight, illness and well being is advanced and formed by stigma in addition to science. Analysis has proven having increased physique fats will increase the chance of sure well being situations similar to diabetes and coronary heart illness. However rising proof suggests some individuals who could also be heavy—similar to those that are clinically categorized as having weight problems, in keeping with their physique mass index (BMI)—are metabolically wholesome. The large reputation of the brand new weight-loss medication is ready towards this evolving understanding—researchers, clinicians and pediatricians are reevaluating how and when to handle weight.
“We’re not treating weight simply to make children smaller,” says Megan O. Bensignor, a pediatric endocrinologist and weight problems drugs specialist on the College of Minnesota, who prescribes the medication in her apply. “We’re making an attempt to deal with them to enhance their long-term well being.”
The brand new medication are usually prescribed within the type of preportioned injector pens, which teenagers can administer at dwelling themselves or with assist from an grownup. They work by activating the identical signaling pathways as glucagon-like peptide 1, or GLP-1, a intestine hormone that the physique produces in response to meals. The medication, technically termed GLP-1 receptor agonists, assist to kickstart the insulin-making course of within the pancreas to convey down blood glucose ranges. GLP-1 medication additionally have an effect on satiety facilities within the mind, inflicting folks to really feel full sooner—so they have a tendency to eat smaller, much less frequent meals. This could “assist stage set the enjoying subject so it may be a bit of extra achievable to have interaction in more healthy behaviors round meals,” says Aaron S. Kelly, co-director of the College of Minnesota’s Heart for Pediatric Weight problems Drugs.
“I don’t actually crave chips or popcorn or issues like that anymore,” says Jeremiah Jimenez, a 15-year-old in Texas who began the weight-loss drug Wegovy in March 2024. Jimenez says he’s at all times had a “larger physique” however quickly gained weight in the course of the pandemic. Extra concerningly his lab exams confirmed a fasting blood glucose stage of 140, and he was identified with prediabetes. He tried keto weight-reduction plan and exercising however didn’t see substantial modifications.
Small medical trials on GLP-1 medication in youthful age teams have proven larger reductions in weight and BMI in contrast with current remedies and customary life-style interventions similar to train and eating regimen. The outcomes led the U.S. Meals and Drug Administration to approve the daily-injected Saxenda (liraglutide) in 2020 and the weekly-injected Wegovy (semaglutide) in 2022. Each can be utilized as weight-loss remedies for kids 12 and older. A JAMA research in Could reported that greater than 60,500 adolescents and younger adults have been prescribed a GLP-1 drug in 2023, a virtually 600 p.c improve from 2020. “We suspect that this dramatic rise is probably going associated to weight administration,” says Joyce Lee, a pediatrician and diabetes specialist on the College of Michigan, who led the research. Whereas GLP-1 drugs have been authorised as remedies for kids with kind 2 diabetes since 2019, pediatric prescriptions spiked after Wegovy’s high-profile FDA approval for adolescents in December 2022, which specified that it may be used for weight reduction.
“For over 20 years as pediatricians, we’ve been speaking about ways in which we are able to handle weight problems, and we have now but to seek out options to beat it in some important and substantive means,” Lee says.
Practically 15 million youngsters in the united stateshave been identified with weight problems. The few drugs historically prescribed for them are sometimes minimally efficient, and bariatric surgical procedure is invasive and dangerous. Adjustments in eating regimen and elevated train, the commonest remedy approaches, may be troublesome to handle in youngsters and adolescents. The brand new weight-loss medication have created “a hope and optimism amongst my sufferers that I’ve frankly not seen earlier than,” says Sarah C. Armstrong, a pediatrician and medical weight administration specialist at Duke Well being. However the medication have additionally introduced new challenges and issues in navigating teenagers’ weight and well being, she says.
“You’ve received this actually dynamic [adolescent] interval of 4 or 5 years—or possibly extra actually [because] the mind nonetheless develops in your mid-20s—the place the impression of environmental elements goes to have lifelong penalties,” says Dan M. Cooper, a professor of pediatrics on the College of California, Irvine, Faculty of Drugs. “If we’re going to make use of these medication in adolescence, there’s received to be an organized try to actually observe the long-term results.”
Trials and Proof
Proof in youngsters shouldn’t be as sturdy as in adults, however just a few medical trials in youthful age teams have examined GLP-1 medication together with life-style modification counseling applications that included train and wholesome consuming. In 2020 a medical trial of 251 children aged 12 to 18 discovered liraglutide—an early-generation GLP-1 drug—minimize BMI by at the least 5 p.c in most contributors after 56 weeks. A 2022 trial of 201 teenagers aged 12 to 18 reported a better remedy response from semaglutide: an about 16 p.c BMI drop after 68 weeks.
“It varies by particular person threat elements, however [researchers think] 5 p.c BMI-weight change might be beginning to see medical profit,” Bensignor says. Kids with weight problems may even see some metabolic modifications, similar to enhancements in hypertension and lipid ranges, she provides. Some knowledge come from children with so-called prediabetes, whose blood glucose ranges are close to the diabetic vary. This analysis means that an 8 to 10 p.c lower in BMI could assist with insulin resistance—that’s why semaglutide’s 16 p.c BMI discount is so interesting, Bensignor says.
The 2022 trial additionally confirmed that semaglutide helped to decrease ldl cholesterol and common blood glucose ranges in youngsters with and with out diabetes. Different research have backed up these findings, even most not too long ago in children as younger as six to 12 years outdated—though the FDA has not authorised any GLP-1 drugs for weight reduction in youngsters beneath age 12. Unwanted side effects in teenagers have been just like these in adults, says Kelly, who was lead writer of the 2020 liraglutide trial: the commonest have been nausea, vomiting and different gastrointestinal issues. Some research have linked GLP-1 medication to a small elevated threat of gastroparesis, or intestine paralysis, which impairs abdomen emptying and digestion. Adversarial results brought about about 10 p.c of contributors within the 2020 trial who obtained the once-daily liraglutide to cease remedy, whereas contributors who obtained the once-weekly semaglutide within the 2022 trial had decrease discontinuation charges of lower than 5 p.c.
Remedy Components
Pediatricians should rigorously think about the wants of their teenage affected person earlier than prescribing GLP-1 medication—not any teen who’s obese or who desires to lose just a few kilos can obtain these drugs. “We very regularly get referrals to have that dialog about whether or not a toddler is an effective candidate or not,” says Mary Ellen Vajravelu, a pediatric endocrinologist on the College of Pittsburgh Medical Heart. “It relies upon quite a bit on their different well being problems.” The American Academy of Pediatrics’ (AAP’s) 2023 pointers on weight problems really helpful GLP-1 medication for kids with excessive BMI or well being situations associated to extra weight, similar to prediabetes, kind 2 diabetes, insulin resistance and fatty liver illness. Armstrong, a co-author of the AAP pointers, notes that children ought to first be screened for current extreme gastrointestinal points or household historical past of thyroid most cancers—some research counsel a slight threat improve related to GLP-1 medication.
Discovering an efficient however tolerable dose varies tremendously amongst people, and GLP-1 drug prescriptions are incrementally elevated over time to assist folks regulate. “The upper the dose, the simpler it’s for weight but in addition the higher the proportion of sufferers who’ve signs like nausea or vomiting,” Lee says. “A few of my sufferers needed to cease the remedy as a result of they’ll’t tolerate it, or we must simply cease the place they’re at a stage that they’ll tolerate.”
Grace, a Connecticut-based 13-year-old, makes use of comparatively low quantities of semaglutide for her insulin resistance and weight reduction—and for the remedy’s anecdotal psychological well being advantages. “Due to her age, we began her at 0.125 [milligram],” says Jennifer, Grace’s mom. “Now she’s at the moment at 0.5.” (Their final names have been withheld for privateness.)
Armstrong and Bensignor say it’s necessary to carefully watch a toddler’s well being and weight all through remedy to verify they aren’t dropping an excessive amount of too rapidly—and that their consuming patterns aren’t turning into overly restrictive. Generally decreasing the dose restores a toddler’s lagging urge for food, Armstrong says, however she provides that behavioral psychologists must be consulted about any indicators of an consuming dysfunction. Researchers don’t know if GLP-1 medication improve the chance of this, however specialists agree additional investigations are wanted.
Lengthy-Time period Unknowns
These medication’ dramatic impact on meals consumption—and probably on vitamin—is without doubt one of the most important causes physicians hesitate about utilizing them in teenagers. Little is thought about long-term results or how the medication could affect a toddler’s future development and improvement. Research in teenagers have solely lasted just a few years at most.
“We all know that the steadiness between vitamin and bodily exercise not solely impacts the kid at that time however for the remainder of his or her life,” says Cooper, who led a report on issues over long-term GLP-1 use in youthful populations. Poor vitamin and train in adolescents are recognized to have an effect on muscle mass and bone mineralization (which assist to extend bone energy and density), Cooper explains. He worries that the potential imbalance in energy and vitality from the weight-loss medication would possibly result in future bone fractures or osteoporosis. Comparable issues have been raised concerning the medication influencing youngsters’ peak and development of puberty.
A spokesperson for Novo Nordisk, the corporate that makes Wegovy and Ozempic (a model of semaglutide that’s used to deal with diabetes), says that “semaglutide didn’t seem to have an effect on development or pubertal improvement in the course of the [2022] trial interval…. We monitor the protection profile of our merchandise and collaborate carefully with regulatory authorities to make sure affected person security, together with in youngsters and adolescents.”
Cooper says that clinicians and researchers ought to monitor teenagers on GLP-1 medication as they age and may exactly measure how a lot they lose in fats, lean tissue or bone mass. He acknowledges that GLP-1 medication would possibly assist in very particular circumstances, similar to teenagers with weight problems and a excessive threat of kind 2 diabetes or coronary heart illness. “To not deal with the kid when you’ve got a drug that will assist them could be an error,” Cooper says. However remedy can solely be a part of the trail ahead: “We’ve this inhabitants of kids, significantly low-socioeconomic children, that discover themselves in an atmosphere the place they turn out to be overweight, the place they don’t have sufficient bodily exercise and so they don’t have entry to sufficient wholesome meals,” he says. “That’s a social and medical drawback, and we have now to pay as a lot consideration to that as we do to creating new medication.”
Vajravelu, Bensignor and Armstrong all say GLP-1 drugs shouldn’t fully substitute wholesome life-style modifications similar to higher bodily exercise, vitamin and sleep. Jimenez, for example, follows an “80-20” rule with meals—consuming extra lean proteins similar to grilled hen and high-fiber vegetables and fruit however nonetheless leaving room for issues like pizza and ice cream. He additionally sticks to a daily exercise schedule: an hour of cardio three days every week and half-hour of weight lifting with a private coach on one other three days. These sorts of modifications must be a part of any weight-loss remedy, and children taking a GLP-1 drug may have help from a wide range of specialists similar to dietitians, social staff and meals training specialists.
“I don’t need folks to suppose that that is actually the simplest factor on this planet, like we’re taking the straightforward means out,” Jimenez says. “It is vitally exhausting to rise up and go work out and to not eat [junk food] and put it down and to portion management since you’re so used to it.”
Future Concerns
Research counsel most individuals who begin a GLP-1 remedy might want to keep on it indefinitely. The medical trials confirmed that youngsters regained weight after stopping remedy. Kelly and his crew at the moment are designing research to grasp if teenagers can cut back the dose over time—and even cease taking the drug completely. “The human physique is exceedingly advanced, and all people’s wired in a different way,” he says. He hopes his future research can additional discover whether or not some folks might briefly use a GLP-1 remedy and “by some means have their physiology reset.” A number of previous research counsel that “if you happen to’re overweight as an adolescent, you then’re prone to stay overweight as an grownup,” Lee says. A GLP-1 drug would possibly get children on a “higher trajectory” with their weight—nevertheless it’s nonetheless too early to inform, she says.
Two research in 2023 discovered that semaglutide was not an economical long-term choice for adolescents. Accessibility and excessive prices of those medication (roughly $1,000 a month) are enormous obstacles for adults, and extra troubling for teenagers, who could expertise protection modifications as they become older, Vajravelu says. “It’s exhausting to prescribe a medicine in childhood that we expect you’ll want for many years—and particularly as a result of it’s doubtless that the remedy entry will likely be interrupted for all kinds of causes, together with insurance coverage modifications and provide points,” she says. And Kelly wonders how interrupted entry would possibly have an effect on somebody throughout their weak teenage years. “That may be a state of affairs that we have to look very rigorously at as a result of we’re placing that particular person in a spot the place they might really feel some desperation to attempt to lose that weight once more with out the remedy,” he says.
Grace’s mom, Jennifer, confronted entry hurdles together with her daughter’s prescription and finally needed to flip to a less expensive choice: compounded semaglutide. Compounded drugs are variations of a drug made by compounding pharmacies fairly than the developer when it’s beneath scarcity. The FDA not too long ago warned of compounded semaglutide’s overdosing dangers. Jeremiah Jimenez’s mom, Suzie Jimenez, who had used Wegovy herself and now takes an analogous remedy known as Zepbound, can afford their prescriptions via her employer’s insurance coverage. However she says that if that scenario modified, “I’d discover a solution to prioritize [the drug] and make it a part of our price range as a result of it’s a lifelong remedy and it appears to be working very successfully for each of us.”
Past reductions in BMI, Bensignor says GLP-1 medication appear to have an effect on some folks’s high quality of life. “My sufferers are feeling higher generally. They’ll transfer higher; they really feel extra snug of their our bodies,” she says. “I feel that is simply one other validation that it’s not their fault, that weight problems has organic underpinnings.”
