A Weight-Loss Surgeon's Perspective on GLP-1 Medications

Weight-loss medications such as Ozempic®, Wegovy®, Zepbound®, and others have transformed obesity treatment for many patients. These medications can help reduce appetite, improve blood sugar control, and lead to meaningful weight loss.
However, bariatric specialists emphasize that medications are only one part of the conversation. Before starting any weight-loss drug, it's important to understand both the potential benefits and the limitations, especially when considering long-term weight management.
For some patients, medication may be the right choice. For others, bariatric surgery may offer a more effective and durable solution.
How Do Weight-Loss Drugs Work?
Most newer weight-loss medications belong to a class known as GLP-1 receptor agonists or dual incretin therapies.
Examples include:
- Wegovy® (semaglutide)
- Ozempic® (semaglutide)
- Zepbound® (tirzepatide)
- Saxenda® (liraglutide)
These medications work by:
- Slowing stomach emptying
- Increasing feelings of fullness
- Reducing appetite
- Helping regulate blood sugar
Many patients experience significant weight loss while actively taking these medications.
What Are the Potential Benefits of Weight-Loss Medications?
Weight-loss medications can provide several benefits, including:
Reduced Appetite
Many patients report fewer cravings and reduced hunger.
Improved Blood Sugar Control
GLP-1 medications were originally developed to treat type 2 diabetes and can improve insulin sensitivity.
Meaningful Weight Loss
Clinical studies have demonstrated substantial weight loss for many patients when combined with lifestyle changes.
Non-Surgical Treatment Option
For patients who are not ready for surgery, medications may provide an effective starting point.
What Are the Limitations of Weight-Loss Drugs?
While these medications can be highly effective, bariatric specialists also discuss several important considerations.
Weight Regain Can Occur
Research has shown that many patients regain weight after discontinuing GLP-1 medications.
Because these medications help control appetite, stopping treatment often allows hunger signals to return.
Long-Term Treatment May Be Necessary
Many patients need to remain on medication long term to maintain results.
This raises important questions regarding:
- Cost
- Insurance coverage
- Medication availability
- Long-term adherence
Side Effects May Limit Use
Common side effects can include:
- Nausea
- Vomiting
- Constipation
- Diarrhea
- Abdominal discomfort
Not every patient experiences these side effects, but they can make treatment difficult for some individuals.
Weight Loss May Include Muscle Loss
Studies suggest that weight loss from GLP-1 medications may include both fat and lean muscle mass.
For this reason, physicians often recommend:
- Strength training
- Adequate protein intake
- Regular exercise
during treatment.
Why Do Bariatric Specialists Discuss Long-Term Solutions?
One of the biggest concerns obesity specialists have is not how much weight patients lose initially, but how much they maintain years later.
Obesity is a chronic disease, and long-term management is often more challenging than initial weight loss.
While medications can be highly effective, specialists encourage patients to think beyond the first six to twelve months and consider:
- Long-term sustainability
- Cost of treatment
- Insurance coverage
- Lifestyle changes
- Overall health goals
When Might Bariatric Surgery Be a Better Option?
Weight-loss medications and bariatric surgery are not competing treatments. In many cases, they can even complement one another.
However, surgery may provide greater long-term weight loss for some patients, particularly those with:
- Severe obesity
- Type 2 diabetes
- Sleep apnea
- High blood pressure
- Repeated weight regain after dieting
- Limited success with medications
Bariatric surgery works differently than medications by creating lasting changes to the digestive system and hormones involved in appetite regulation.
Procedures such as:
- Gastric Sleeve Surgery
- Gastric Bypass Surgery
- Duodenal Switch Surgery
have been shown to produce substantial and durable weight loss while improving many obesity-related conditions.
