Sufferers who take blockbuster medication like Wegovy or Ozempic for weight reduction could face life-threatening issues in the event that they want surgical procedure or different procedures that require empty stomachs for anesthesia. This summer time’s steering to halt the remedy for as much as every week could not go far sufficient, both.
Some anesthesiologists within the U.S. and Canada say they’ve seen rising numbers of sufferers on the weight-loss medication who inhaled meals and liquid into their lungs whereas sedated as a result of their stomachs have been nonetheless full — even after following commonplace directions to cease consuming for six to eight hours prematurely.
The medication can sluggish digestion a lot that it places sufferers at elevated threat for the issue, known as pulmonary aspiration, which may trigger harmful lung harm, infections and even dying, mentioned Dr. Ion Hobai, an anesthesiologist at Massachusetts Basic Hospital in Boston.
“That is such a severe form of potential complication that everyone who takes this drug ought to find out about it,” mentioned Hobai, who was among the many first to flag the problem.
Practically 6 million prescriptions for the category of medication that embrace Wegovy and Ozempic have been written between January and Could within the U.S. for individuals who don’t have diabetes, in keeping with Komodo Well being, a well being care expertise firm. The medication induce weight reduction by mimicking the actions of hormones, discovered primarily within the intestine, that kick in after individuals eat. Additionally they goal indicators between the intestine and the mind that management urge for food and emotions of fullness, and by slowing how briskly the abdomen empties.
In June, the American Society of Anesthesiologists issued steering advising sufferers to skip every day weight-loss medicines on the day of surgical procedure and maintain off on weekly injections for every week earlier than any sedation procedures. Dr. Michael Champeau, the group’s president, mentioned the motion was primarily based on anecdotal stories of issues — together with aspiration — from across the nation.
It’s not clear what number of sufferers taking the anti-obesity medication could also be affected by the problem. However as a result of the results might be so dire, Hobai and a gaggle of colleagues determined to talk out. Writing in the Canadian Journal of Anesthesia, they known as for the drug to be stopped for even longer — about three weeks earlier than sedation.
That accounts for a way lengthy semaglutide, the lively remedy in Wegovy, stays within the physique, mentioned Dr. Philip Jones, a Mayo Clinic anesthesiologist who can also be deputy editor-in-chief of the journal.
“When 90% of it’s gone, which is after three weeks, hopefully all the pieces ought to return to regular,” Jones mentioned.
Champeau and Jones each acknowledged there’s not sufficient proof to say for sure how lengthy semaglutide ought to be held to make anesthesia secure. Many sufferers gained’t see suppliers far sufficient prematurely to cease the drug three weeks earlier than procedures, Champeau famous.
Aspiration happens in certainly one of each 2,000 to three,000 operations that require sedation, and virtually half of sufferers who aspirate throughout surgical procedure develop a associated lung damage. However case stories present current sufferers on semaglutide had issues even once they stopped meals so long as 20 hours earlier than their procedures.
“There’s nothing that claims for those who quick twice as lengthy, will probably be OK,” Champeau mentioned.
Among the many a number of stories detailing probably severe issues was certainly one of Hobai’s sufferers, a 42-year-old man in Boston who lately started taking Wegovy, needed to be intubated and suffered respiratory failure that put him in intensive care. He aspirated meals that remained in his abdomen regardless of fasting for 18 hours.
In Chapel Hill, North Carolina, a 31-year-old-woman on a low dose of Ozempic had fasted for 10 hours earlier than a routine endoscopy previous to bariatric surgical procedure final fall. The process needed to be stopped as a result of stable meals remained in her abdomen and she or he was at excessive threat for aspiration, the report mentioned.
Since then, docs have seen dozens of comparable circumstances as use of the weight-loss remedy has grown, mentioned Dr. Elisa Lund, an anesthesiologist on the College of North Carolina at Chapel Hill Faculty of Medication. “It has exponentially elevated,” she mentioned.
Hobai is finishing a retrospective examine of just about 200 sufferers taking semaglutide. Whereas it’ll be printed later this yr, the work to date seems to verify a small examine from Brazil, he mentioned. In that examine, a couple of quarter of sufferers taking semaglutide had residual meals of their stomachs throughout procedures requiring sedation — even after stopping the drug for 10 days.
The American Society of Anesthesiologists advises docs who’re doubtful to deal with sufferers who haven’t paused the drug as if they’ve full stomachs, which may imply utilizing several types of sedation protocols or delaying procedures, if attainable. Jones added that analysis is urgently wanted to replace pointers for docs and sufferers.
Novo Nordisk, which makes Ozempic, Wegovy and related medication, mentioned the agency’s medical trial and post-marketing security information didn’t present that the medicines led to aspiration. However the drugmaker famous that the medicines are recognized to trigger delayed emptying of the abdomen and that the labels warn of attainable gastrointestinal unintended effects.
Stopping the medicines for 3 weeks may cause issues, too. Sufferers with diabetes will want one other method to management their blood sugar and people looking for to shed extra pounds could regain some, Hobai mentioned.
Hobai suggests that folks utilizing Wegovy and related medication inform their docs earlier than sedation and focus on the dangers and advantages.
“In case you’re taking this drug and also you want an operation, you’ll need to have some additional precautions,” he mentioned.
