Weighing the Risks: Mounting Concerns Surround GLP-1 Weight Loss Drugs
The growing popularity of drugs like semaglutide for weight loss is shadowed by increasing reports of serious side effects and challenges with long-term use, prompting calls for greater patient awareness and a more holistic approach to health.
Both starting and stopping these medications can be dangerous, according to emerging research and clinicians on the front lines of patient care. Dr. Roberts DC, at Health Utah, is among those witnessing the complexities firsthand, helping patients navigate both the initial effects and the aftermath of discontinuing these drugs.
One particularly concerning case involved a 16-year-old girl who experienced debilitating abdominal pain after a short course of semaglutide. “She came into my clinic with excruciating pain,” Dr. Roberts recounts. “She couldn’t even drink water without severe abdominal distress. Even though she was on Semaglutide for only a short time, the pain persisted for six months after she stopped injecting it.” Fortunately, with targeted care, her pain resolved within weeks, and remarkably, she did not experience any weight loss throughout the ordeal. However, Dr. Roberts notes that not all patients are so fortunate, with some experiencing more severe or prolonged symptoms.
FDA Data Reveals Thousands of Adverse Events
Since 2018, the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database has recorded 10,000 serious or life-threatening reactions potentially linked to GLP-1 agonists. Tragically, these medications have been implicated in 162 deaths, a number that surged by 40% in a recent six-month period coinciding with increased usage.
Despite these figures, Dr. Roberts emphasizes perspective. “The reality is that the risk of death while taking these drugs is probably no greater than many other very common drugs,” he states. “This just underscores the general principle that there are inherent risks in taking any kind of medication.” However, a 1997 study highlighted a systemic issue: doctors often fail to adequately inform patients about potential risks. This underscores the importance of proactive patient education and informed decision-making.
Known and Emerging Side Effects
The Semaglutide label already lists a range of potential side effects, including:
- Pancreatitis
- Thyroid tumors, including cancer
- Severe gastrointestinal disease such as stomach paralysis and intestinal blockage
- Bloating, severe constipation, nausea, and vomiting
- Acute kidney injury
- Hypoglycemia
- Gallbladder disease
- Allergic reactions
- Vision changes
- Rapid or pounding heartbeat
- Suicidal behavior and ideation
However, recent studies are uncovering additional concerns not currently included on the official label. A 2024 study published in Diabetes, Obesity and Metabolism found that up to 60% of weight loss achieved with liraglutide can be attributed to lean muscle mass. “That means that for every three pounds you lose, almost two of them could be from muscle,” Dr. Roberts explains, highlighting the potential for weakened physical function and a slowed metabolism.
Further research, a 2025 population study in JAMA Ophthalmology, indicates a threefold increased risk of non-arteritic Anterior Ischemic Optic Neuropathy, a form of sudden vision loss. An analysis of FAERS data reported in Medscape in 2025 also revealed incidences of anosmia (loss of smell), dysgeusia (altered taste), tinnitus (ringing in the ears), dysphonia (voice changes), hearing disabilities, and gastroesophageal reflux disease.
The Rebound Effect: Weight Regain After Stopping GLP-1 Agonists
Discontinuing GLP-1 agonists often leads to significant weight regain. Research published in Diabetes, Obesity and Metabolism showed that 327 participants regained two-thirds of their lost weight within one year of stopping treatment. Compounding the issue, additional research published in Sciencedirect suggests that the regained weight has a higher fat-to-muscle ratio, further lowering metabolic rate and increasing metabolic dysfunction.
“Anyone coming off these drugs must understand this near-certain outcome if they want to prevent it,” Dr. Roberts emphasizes. He advocates for viewing these medications as a “jump start” to optimal health, rather than a standalone solution.
A Holistic Approach to Sustainable Weight Management
Maintaining weight loss after discontinuing GLP-1 agonists requires a comprehensive strategy focused on addressing underlying health issues. “The first step is to accept the fact that there is no short cut to optimal health and weight,” Dr. Roberts asserts. “The laws of health cannot be circumvented with any kind of medication.”
He recommends identifying and addressing underlying factors that contribute to weight gain, such as:
- Depression
- Insomnia
- Hormone imbalances
- Gut bacteria imbalances
- Liver/gallbladder problems
- Insulin resistance
- Leptin resistance
- Toxins and deficiencies
At Health Utah, patients undergo a specialized, non-invasive body scan to assess their physiological state, stress levels, and potential underlying conditions. This is complemented by a proprietary questionnaire developed from Dr. Roberts’ 30 years of experience, providing a comprehensive evaluation. Based on these assessments, a customized care plan is developed, potentially including therapies, supplementation, hypnotherapy, and coaching.
Finally, Dr. Roberts stresses the importance of a personalized, sustainable food plan. “The shots work partially because they reduce the calories you eat. But the shots ultimately fail, like almost every other diet, precisely because they reduce the calories you eat. Calorie reduction never works long term because your body’s metabolism slows down when threatened by reduced calories.” At Health Utah, they focus on tailoring food plans to individual body needs, avoiding restrictive diets or fad approaches.
“Take these steps and you will likely be able to maintain the weight you lost while on the shots and get healthier at the same time, something the shots could never do,” Dr. Roberts concludes.
Special Offer: Partner Up for Success
Research suggests that individuals are more successful in their weight loss journeys when they have a support system. A British study found that both men and women had almost twice as much success losing weight when they did it with a partner. Health Utah is currently offering their most popular weight loss package for $59 for two people, including testing, a 17-page report, the proprietary survey, and a consultation with Dr. Roberts. (The scan alone normally costs $300 per person.)
