Thinking About GLP-1 Medications? Here's What I Tell My Patients

A thoughtful conversation about one of the biggest advances in medicine—and why the prescription is only the beginning.

A few years ago, almost no one had heard of medications like semaglutide or tirzepatide. Today, it's hard to scroll through the news or social media without seeing a story about them. Some articles describe them as miracle drugs. Others warn that they're dangerous shortcuts. As is often the case in medicine, the truth lies somewhere in the middle.

Patients often ask me, "What do you think about GLP-1 medications?" My answer usually surprises them because it isn't a simple yes or no.

I think these medications represent one of the most significant advances we've seen in the treatment of obesity and metabolic disease in decades. For the right person, they can be truly life-changing. At the same time, they aren't magic, and they certainly aren't the whole story. Like any medical treatment, they work best when they're thoughtfully prescribed, carefully monitored, and combined with healthy habits that support long-term success.

One of the most important things we've learned over the past several years is that obesity is far more complex than we once believed. It's not simply a matter of eating too much or exercising too little. Body weight is influenced by genetics, hormones, brain signaling, appetite regulation, metabolism, sleep, stress, medications, the food environment, and many other factors. That's one reason long-term weight loss has been so difficult for so many people. Our bodies are remarkably good at defending the weight they've become accustomed to, even when we're trying our best to change it.

GLP-1 medications help address part of that biology.

GLP-1, or glucagon-like peptide-1, is a hormone our bodies naturally produce after we eat. It plays several important roles, including helping us feel satisfied after a meal, slowing how quickly food leaves the stomach, and supporting healthy blood sugar regulation. The medications are designed to mimic or enhance these natural effects. Many people notice they feel full sooner, stay satisfied longer, and spend less time thinking about food. That last observation is one I hear frequently. Patients often describe it as finally having some quiet around food after years of feeling like it occupied far too much mental space.

That doesn't mean the medication removes the need for healthy choices. Rather, it may make those choices feel more achievable.

One of the misconceptions I'd like to gently challenge is the idea that taking a GLP-1 medication is somehow "the easy way out." We don't tell people with asthma that using an inhaler is taking the easy way out. We don't tell someone with high blood pressure that medication is a moral failure. Obesity is a chronic medical condition influenced by biology as well as behavior, and treating it thoughtfully should carry no more stigma than treating diabetes or high cholesterol.

That said, I don't believe these medications are appropriate for everyone.

Every treatment decision begins with understanding the individual sitting in front of me. What are your goals? What has your weight history been? What have you already tried? What other medical conditions do you have? Are you taking medications that might influence weight? What does your relationship with food look like? What concerns do you have? Sometimes a GLP-1 medication becomes an important part of the plan. Sometimes another approach makes more sense. Good medicine begins with asking the right questions, not assuming the same answer fits every patient.

One thing I spend a great deal of time discussing with patients is what happens after the prescription is written. That's because I don't see medication as the destination. I see it as an opportunity.

If your appetite is reduced and you're eating less, what will those meals look like? Are you getting enough protein to help preserve muscle? Are you continuing to move your body in ways that build strength? Are you drinking enough fluids? How are you managing constipation or nausea if they occur? How are you feeling emotionally as your relationship with food changes?

Those conversations matter just as much as choosing the medication itself.

I also encourage patients to think beyond the number on the scale. Clinical trials have demonstrated impressive weight loss with GLP-1 medications, along with improvements in blood sugar, blood pressure, and several other markers of metabolic health. Those are meaningful outcomes. But what I find most rewarding are the changes patients don't always expect. They tell me they have more energy to play with their children, their knees hurt less, they're sleeping better, or they finally feel hopeful again after years of frustration.

Those are the victories I celebrate.

Like any medication, GLP-1 receptor agonists have potential side effects and are not appropriate for every individual. Gastrointestinal symptoms such as nausea, constipation, diarrhea, or vomiting are among the most common, particularly when starting treatment or increasing the dose. Most improve with time and thoughtful dose adjustments, but it's important to have ongoing communication with your healthcare team. There are also specific medical conditions and family histories that influence whether these medications are a good choice, which is why careful screening is so important before beginning treatment.

Perhaps the biggest misconception is that these medications "fix" weight once and for all. Obesity is a chronic disease, and like many chronic conditions, it often requires long-term management. For some people, that may mean continuing medication. For others, lifestyle changes and ongoing support become the focus over time. There isn't one right path. The goal is to create a plan that's realistic, sustainable, and tailored to the individual.

I often tell patients that my job isn't simply to help them lose weight. It's to help them become healthier while they're losing weight—and healthier long after they're done losing it.

That's an important distinction.

If someone loses weight but also loses significant muscle, becomes undernourished, stops exercising, or develops an unhealthy relationship with food, we've missed the bigger picture. Success isn't defined by becoming lighter. It's defined by becoming stronger, healthier, and more capable of living the life you want.

When used thoughtfully and for the right reasons, GLP-1 medications can be an extraordinary tool. But they're still just that—a tool.

The real transformation comes from what we build around them.
