Christina had tried weight loss programing and train earlier than. The burden all the time got here off however then crept again on, particularly after she gave beginning to her son in 2022.
She had hoped {that a} new class of weight-loss medication would possibly lastly supply one thing completely different. Obesity remedies corresponding to Wegovy and Zepbound had simply arrived on the scene, serving to individuals slim down with unprecedented ease. However the price ticket of those GLP-1 medication put them out of attain. Christina’s health insurance wouldn’t cowl the price.
Determined for an additional possibility, Christina enrolled in a medical trial that assured a number of months on a blockbuster weight-loss remedy—after which the potential for one thing extra. (Christina, a Texas girl in her early 50s, requested that her final identify be withheld to guard her privateness about her weight-loss therapy.)
That one thing extra wasn’t one other injection or tablet, however a one-time process utilizing a brand new medical device. And as a substitute of focusing on the abdomen or mind, it targeted on the intestine itself: rewiring how part of the higher gut, often known as the duodenum, processes vitamins and regulates metabolism.
Carried out through a minimally invasive endoscopic system, this strategy is designed to assist individuals who need to cease taking GLP-1 medication. The objective is to lock in the advantages with out the excessive prices, weekly jabs, or lingering uncomfortable side effects. And in 2026, the primary firm to develop such a tool is prone to search clearance to carry it to sufferers.
“We’re creating a brand new therapeutic space,” says Harith Rajagopalan, cofounder and chief govt of that firm, Fractyl Health, based mostly in Burlington, Mass.
Resetting Metabolism for Lasting Weight Loss
You possibly can consider these techniques as a center floor between medication and bariatric surgery. The endoscope is a slim, versatile tube geared up with a digital camera and a guidewire that leads a catheter into the digestive system. Medical doctors ship the instruments down the throat to allow them to view and modify the intestines from the within—transforming intestine tissue and recalibrating its response to meals with no single incision. The process takes about an hour or so, and sufferers usually go house the identical day.
To know how the therapy works, it helps to first perceive what goes mistaken within the intestine throughout years of unhealthy consuming. As diets excessive in sugar and fats bombard the duodenum, the liner there turns into infected and its regular signaling pathways distorted. Mucosal cells within the tissue develop abnormally and propagate these maladaptive adjustments, locking in a dysfunctional sample that drives cravings, weight acquire, and insulin resistance.
The Fractyl system overcomes these entrenched adjustments. It really works by intentionally injuring the tissue, utilizing near-boiling water to burn off diseased cells on the intestinal lining. A pure therapeutic course of then kicks in, producing a contemporary layer of wholesome tissue and re-establishing correct metabolic management.
“You see regrowth at about two weeks, and it continues till the mucosa seems fairly regular,” says Alan Cherrington, a physiologist at Vanderbilt College College of Medication who consults for Fractyl.
Preliminary results from the medical trial that Christina joined, termed the Remain-1 study, point out that the process is working as meant to stabilize weight after GLP-1 therapy. Three months after stopping Zepbound, examine individuals who underwent the Fractyl process usually held their weight regular or continued to drop pounds, whereas those that acquired a sham therapy noticed the quantity on their scales climb steadily upward.
The outcomes are “truthfully higher than I believed they have been going to be,” says one of many medical doctors main the trial, Shelby Sullivan, a gastroenterologist and obesity-medicine specialist on the Dartmouth Hitchcock Medical Middle in Lebanon, N.H.
Sullivan cautions towards drawing agency conclusions, given the small variety of individuals and quick follow-up to date. However anybody watching the sector gained’t have to attend lengthy for clearer solutions. “By six months,” she says, “we completely will know if it’s working or not.”
Subsequent-Technology Units for Weight problems
If the six-month information show lasting weight upkeep—full trial readouts are anticipated in 2026—Fractyl then intends to hunt regulatory clearance to market what might change into the primary system particularly sanctioned for post-GLP-1 weight management.
However Fractyl is hardly alone in pursuing this therapeutic frontier. Endogenex, an organization based mostly in Plymouth, Minn., is utilizing a versatile, expandable circuit board to use pulsed electric fields on to the duodenal wall to burn away the issue cells. In the meantime, TeCure, in South Korea, and Aqua Medical, in Pleasanton, Calif., are utilizing lasers and radiofrequency-heated water vapor, respectively, to attain an analogous transforming of the intestine lining.
“In the long run, it’s completely different strategies to do the identical factor,” says Pichamol Jirapinyo, a bariatric endoscopist at Brigham and Ladies’s Hospital in Boston and a cofounder of Bariendo, a community of 10 nonsurgical weight-loss clinics throughout the United States. Whereas ongoing trials might make clear variations in efficacy and security, Jirapinyo (who consults for Fractyl) expects operational options corresponding to ease of use and process time to play a decisive function in figuring out uptake amongst practitioners.
Timing of market entry is vital, too—and Fractyl, now main the pack, is anticipated to ship the primary large-scale medical outcomes. These outcomes, from the trial that Sullivan is main, might set the tone for a whole class of recent device-based weight problems remedies aiming to protect the positive factors of GLP-1 medication, notes Endogenex CEO Stacey Pugh. “If they’re profitable, it’s going to blow this subject extensive open,” she says.
Different Submit-GLP-1 Units
Not everyone seems to be satisfied that resurfacing the duodenum is the way in which to go. In Europe, the previous yr noticed the arrival of a brand new weight-loss system referred to as Reset that—whereas not explicitly licensed to be used in a post-GLP-1 drug setting—introduces a sleevelike liner to the duodenum that bodily prevents contact between meals and the intestine wall. That system have to be eliminated inside a yr, nevertheless, providing solely a short lived repair.
Different endoscopic approaches goal the abdomen: One in common use today applies sutures to fold the abdomen and shrink its dimension, whereas another, more experimental method burns off abdomen tissue that regulates the secretion of appetite-stimulating hormones.
These stomach-directed strategies might supply a logistical benefit given the relative robustness and accessibility of the abdomen, explains Andrew Storm, a therapeutic endoscopist at Wake Forest College in Winston-Salem, N.C. “The duodenum is paper skinny, as in comparison with the abdomen, which is sort of a thick neoprene bag,” he says.
Regulatory clearance for Fractyl would permit the corporate to instantly promote its product for post-GLP-1 weight upkeep—one thing that Boston Scientific, maker of the most widely used stomach-suturing device, isn’t legally permitted to do except it engages in a brand new spherical of medical trials. And that distinction might give duodenal therapies an edge in advertising and marketing. However Storm, who consults for Boston Scientific and has additionally participated in trials of the Endogenex system, raises considerations concerning the complexity of duodenal remedy. “It simply introduces a complete different stage of issue for the endoscopist that that I feel will influence scalability,” he says.
Holding On to Laborious-Gained Progress
For sufferers like Christina, the controversy over abdomen versus duodenum, or one firm’s system versus one other’s, is essentially tutorial. What issues for her is that the 50 kilos she misplaced on Zepbound—almost 20 % of her physique weight—has stayed off to date, a stability that she attributes to the Fractyl system. As a result of the trial is randomized and blinded, it’s potential she really acquired the sham process. However Christina is pretty assured that she obtained the true factor.
Her reasoning comes from small however telling moments, like when her husband was cooking smoked pork burnt ends, sending up the type of wealthy aromas that after would have despatched her straight to the desk. “It smelled actually good, however I didn’t have any want to chow down on it,” Christina says.
Experiences like Christina’s trace on the tantalizing promise of a long-lasting answer after drug-assisted weight reduction, however medical-device improvement calls for greater than anecdotes. With pivotal trial readouts on the horizon, the yr forward might decide whether or not these units stay hopeful prototypes or change into validated instruments within the subsequent period of weight problems care.
