Diabetes & Weight Loss Drugs May Curb Alcohol Consumption, New Study suggests
A growing body of research indicates that medications commonly prescribed for diabetes and weight loss – including ozempic and Wegovy – could offer a surprising benefit: reducing alcohol intake. A new study published this month in Scientific Reports from the Fralin Biomedical Research Institute at Virginia Tech,reveals that GLP-1 agonists appear to slow the absorption of alcohol into the bloodstream,possibly lessening it’s impact on the brain.
The research offers a novel approach to tackling alcohol use disorder, a meaningful public health concern affecting roughly one in ten U.S. adults. chronic, heavy drinking is linked to numerous health problems, including liver disease, heart disease, and certain cancers.
Key Findings
Participants taking GLP-1 medications exhibited substantially lower breath alcohol concentration after consuming alcohol, compared to those not on the drugs. Participants on GLP-1s also self-reported feeling less intoxicated.
“People who drink know there’s a difference between nursing a glass of wine and downing a shot of whiskey,” explained a senior researcher at the Fralin Biomedical Research Institute. “A shot causes blood-alcohol levels to rise much faster, and that speedy spike feels stronger.” The study suggests that by slowing alcohol’s entry into the bloodstream, GLP-1s could diminish its effects and, consequently, reduce consumption.
A Different Mechanism of Action
Existing medications for alcohol use disorder, like naltrexone and acamprosate, primarily target the central nervous system. However, the study’s corresponding author noted that “Our preliminary data suggest that GLP-1s suppress intake through a different mechanism.” The drugs work by slowing gastric emptying, the rate at which food and liquids leave the stomach, which in turn slows the rise in blood alcohol levels.
Study Details & Methodology
The pilot study involved twenty adults with a body mass index (BMI) of 30 or higher. Half were already taking GLP-1 medication, while the other half served as a control group. Before the experiment, all participants fasted and than consumed a snack bar to standardize stomach contents.Researchers meticulously monitored participants’ blood pressure, pulse, breath alcohol concentration, and blood glucose levels.
Ninety minutes later, each participant was given an alcoholic drink to finish within ten minutes. Over the following hour, they repeatedly assessed their level of intoxication, cravings, appetite, and the drink’s taste, rating their level of intoxication on a scale of zero to ten. Participants then remained in a recovery area while their alcohol levels gradually decreased, with breath alcohol measured every 30 minutes and blood glucose levels checked twice.Final follow-up questions were administered after three hours, and participants were onyl released once their breath alcohol levels fell below 0.02 percent and were cleared by a study physician.
A Legacy of Research & a Promising Future
The study’s origins trace back to a faculty retreat at the Fralin Biomedical Research Institute and was spearheaded by Warren Bickel, a professor and director of the Addiction Recovery Research Center, who passed away in 2024.The research was also informed by an analysis of social media posts on Reddit, where users reported reduced alcohol cravings while taking medications for type 2 diabetes and obesity.
“His guidance shaped every stage of this research,” said Fatima Quddos, a graduate researcher in Bickel’s lab and the study’s first author. “His passion for scientific discovery continues to inspire me.” Quddos, who recently earned her doctorate, emphasized the potential for offering “new hope to individuals struggling with addiction.”
While acknowledging the study’s small sample size, researchers are optimistic that the findings will pave the way for larger, long-term trials to investigate the potential of GLP-1 medications as a therapy for reducing alcohol use. “Using a drug that’s already shown to be safe to help people reduce drinking could be a way to get people help fast,” a researcher stated.
