New weight-loss medication could be a medical marvel or the next health crisis

Health care providers have a responsibility to ensure that we are not replacing one public health crisis with another

Fox News medical contributor Dr. Nicole Saphier discuses top headlines relating to health and wellness on ‘Fox & Friends Weekend.’ As a physician, I have witnessed countless medical breakthroughs that have transformed patient care and improved lives. One such innovation is the advent of GLP-1 agonists, a class of medications initially developed to treat type 2 diabetes but have since gained unprecedented popularity for their efficacy in weight loss.

These drugs, such as semaglutide, have garnered attention for their ability to help people shed significant amounts of weight, improve blood sugar control, and reduce the risk of cardiovascular disease. However, while the benefits are undeniable, the rapid adoption of these medications raises concerns about potential long-term consequences, dependency, and the broader implications for our relationship with food and health.

GLP-1 agonists work by mimicking the action of the hormone glucagon-like peptide-1, which increases insulin secretion, decreases glucagon release and slows gastric emptying. This results in reduced appetite, increased satiety, and improved glycemic control, making these medications incredibly effective for weight loss and managing diabetes.

For individuals who have struggled with weight loss through diet and exercise alone, these medications offer hope and a tangible solution. Clinical trials have shown that patients on these medications can lose up to 15-20% of their body weight, a result previously achievable only through bariatric surgery.

The implications of this weight loss are profound. Obesity is a major risk factor for numerous chronic diseases, including type 2 diabetes, cardiovascular disease and certain cancers. By helping patients lose weight, GLP-1 agonists can reduce the incidence of these conditions, potentially saving lives and reducing the burden on healthcare systems.

For individuals who have struggled with weight loss through diet and exercise alone, these medications offer hope and a tangible solution.

However, the very effectiveness of GLP-1 agonists also raises red flags. As more people turn to these drugs for weight loss, there is a growing concern that we may be fostering a dependency on medication rather than addressing the root causes of obesity.

Unlike lifestyle changes, which require ongoing effort and can lead to sustainable weight management, GLP-1 agonists offer a quick fix that may lead to complacency in adopting healthier behaviors. Patients may become reliant on these medications to maintain their weight, creating a scenario where they are dependent on a drug for the long term.

Limited studies already show that on average, people gain back two-thirds of the weight they've lost within a year of stopping the medication, with some people consuming more daily calories than before they began the medication.

Also, the long-term safety of GLP-1 agonists is still unknown. While these drugs have been shown to be safe and effective in clinical trials, these studies typically last only a few years. We do not yet have data on the effects of taking these medications for decades, so it is concerning that people are being prescribed them without an end date. Could there be unforeseen side effects or health risks that emerge over time?

There are already known risks to these medications, nausea being the most common to intestinal blockages, which can be fatal. Animal studies suggest a possible risk of thyroid cancer with these medications, but it will take long-term data to know if this translates to humans as well.

The history of medicine is replete with examples of drugs that were initially hailed as breakthroughs but later found to have serious consequences. The opioid crisis, which began with the widespread prescription of what were thought to be safe painkillers, serves as a stark reminder of the potential dangers of over-reliance on medication.
