A Necessary and Sober Look at the Risks and Long-Term Realities

Dr. Myriam Delgado provides a physician’s analysis of the new class of GLP-1 weight loss drugs, examining their powerful benefits for metabolic health, the associated risks and side effects, and their true role in a long-term wellness strategy.

The New Era in Weight Management: A Physician's View on Today’s Weight Loss Drugs

Hello, I'm Dr. Myriam Delgado. Every day in my clinic at Biolife Health Center, I sit with patients who share their deeply personal and often painful journeys with weight management. For many, it has been a lifelong battle against biology, environment, and frustration. Now, a new conversation is taking place. It’s filled with names like Ozempic, Wegovy, and Mounjaro, and a powerful mix of dramatic headlines, celebrity testimonials, and genuine, heartfelt hope fuels it.

The intense public interest is undeniable. With obesity rates in the U.S. affecting over 40% of adults, the desire for practical solutions is immense. This is reflected in recent consumer surveys, like one from NIQ, which shows a remarkable willingness among people to invest in their health. Weight management is a key focus. But as these new medications move from the abstract into the real lives of my patients, I see an urgent need for a calm, evidence-based discussion. Are they a miracle cure? A risky shortcut? Or are they something else entirely: a powerful new tool for managing a chronic disease? Let’s explore what you truly need to know.

What Are These Drugs and How Do They Work?

The medications causing this seismic shift are primarily in a class called GLP-1 (glucagon-like peptide-1) receptor agonists. That’s a mouthful, so let's simplify it.

Think of GLP-1 as one of your body’s natural “fullness signal” messengers. After you eat, this hormone is released from your gut, traveling to your brain to say, "We've got enough fuel, you can stop eating now." It also signals your stomach to slow down its emptying process, making you feel full for longer.

These new drugs are synthetic versions of this hormone that are much more potent and last longer than your body's natural GLP-1. By activating these same receptors, they do three key things:

Reduce Appetite: They directly impact the hunger centers in your brain, quieting the "food noise" many people struggle with.
Increase Satiety: They slow stomach emptying, so you feel full faster and stay full longer.
Improve Blood Sugar Control: They stimulate insulin release when blood sugar is high, which is why they were first developed as diabetes medications.

The Undeniable Benefits: The "Miracle" Side of the Story

The reason these drugs are so transformative is that their benefits go far beyond the number on a scale. We are not just treating weight; we are treating the complex metabolic disease of obesity.

Clinically Substantial Weight Loss: Clinical trials have shown that patients can lose 15% to over 20% of their body weight. For a 250-pound person, that’s a loss of 37 to 50 pounds. This level of reduction was previously achievable only through bariatric surgery.
Cardiometabolic Health Improvements: This, to me as a physician, is the most compelling part. I see patients’ high blood pressure come down. Their cholesterol profiles improve. Most impressively, I see patients with pre-diabetes return to normal blood sugar levels, dramatically reducing their risk of developing full-blown type 2 diabetes.

I think of a patient of mine, let's call him David, a 52-year-old man with a family history of heart disease. He had pre-diabetes and high blood pressure and had tried countless diets. For him, starting one of these medications wasn't about fitting into smaller clothes. It was about seeing his blood sugar normalize and his blood pressure improve. The weight loss was a welcome effect, but the true victory was seeing his risk for a future heart attack or stroke decrease substantially. For David, this was no shortcut; it was a lifeline.

The Necessary Cautions: The "Risky" Side of the Story

No effective medication is without risks, and these are no exception. It is my responsibility to ensure my patients understand both sides.

Common Side Effects: The most frequent issues are gastrointestinal, which makes sense given the drugs' effect on the digestive system. Nausea, vomiting, diarrhea, constipation, and abdominal discomfort are common, especially when starting the medication or increasing the dose. For most, these are manageable, but for some, they are severe enough to stop treatment.
Serious, Less Common Risks: The labels carry warnings for more serious potential risks, including pancreatitis (inflammation of the pancreas), gallbladder problems, and a risk of thyroid C-cell tumors (seen in animal studies). This requires a careful discussion of a patient's personal and family medical history.
The Rebound Reality: This is a crucial point that is often lost in the excitement. These medications work as long as you are taking them. When you stop, the hormonal signals revert, the appetite returns, and the weight is very often regained. This means we must view them not as a short course of treatment, but as a long-term management strategy for a chronic disease, much like medication for high blood pressure.
Muscle Loss Concerns: Weight loss is never just fat loss. A portion of it is lean muscle mass. There is a concern that the rapid weight loss from these drugs could lead to a disproportionate loss of muscle if not paired with adequate protein intake and resistance exercise.

A Tool, Not a Panacea: The Long-Term Impact

The rise of these drugs is happening alongside a larger conversation about our food systems and lifestyles. A McKinsey survey highlighted weight management as a key focus in wellness trends for 2025, showing that people are seeking holistic health, not just a quick fix. This is exactly the right context.

These medications are not a substitute for a healthy lifestyle; they are a tool that can make a healthy lifestyle more attainable. They can quiet the constant biological drive to eat that many people with obesity face, creating the headspace to build sustainable habits. The discussions around our food environment—the prevalence of ultra-processed foods that are designed to be overeaten—are still vital. A drug can help manage your response to that environment, but it doesn’t change the environment itself.

The most successful outcomes I see in my practice are with patients who use the medication as a catalyst. They work with a dietitian, they start a regular exercise routine, and they address the behavioral aspects of eating. The medication gives them the biological support to make those changes stick.

Summary: A Transformative but Complex Tool

The new class of GLP-1 weight loss drugs represents a true breakthrough in treating the chronic disease of obesity. They offer powerful benefits that extend well beyond weight reduction, including major improvements in blood sugar, blood pressure, and cardiovascular risk factors. However, they are not without downsides, including common gastrointestinal side effects, rarer but serious risks, and the near-certainty of weight regain upon cessation. Viewing these medications as a short-term fix is a mistake. Their greatest value is as a long-term tool to support—not replace—the foundational pillars of health: nutrition, physical activity, and sustainable behavior change.

Final Thoughts

We are at an important turning point in our understanding and approach to obesity. These new medications are truly making a positive difference in the lives of many of my patients, bringing hope where it was once hard to find. But it’s essential to remember that hope needs to be paired with wisdom. A pill alone can’t solve a complex problem that involves our biology, mental health, and society.

Still, it can offer a helpful biological boost, giving people a valuable edge as they work towards a healthier lifestyle. The conversation is just getting started, and I want to make sure it’s one that’s grounded in science, realistic, and always focused on the long-term well-being of each person.

Frequently Asked Questions (FAQs)

Who is a good candidate for these medications?
Typically, they are prescribed for individuals with a body mass index (BMI) of 30 or greater, or a BMI of 27 or greater with a weight-related health condition like type 2 diabetes, high blood pressure, or high cholesterol.
Is it true you have to take these drugs forever?
Because obesity is a chronic condition, these medications are generally intended for long-term use. Discontinuing the drug usually leads to the return of appetite and subsequent weight regain. The decision on duration is a personal one made with your doctor.
What is the difference between Ozempic and Wegovy?
They are the exact same drug, semaglutide. Ozempic is FDA-approved and dosed for the treatment of type 2 diabetes (though it causes weight loss), while Wegovy is FDA-approved and dosed specifically for the treatment of obesity.
Can I get these drugs just to lose 10-15 pounds?
These are powerful prescription medications intended for treating the clinical disease of obesity and are not recommended or approved for cosmetic weight loss. Using them for smaller amounts of weight loss exposes a person to potential risks without the same level of medical benefit.
How much do these medications cost?
Without insurance, the list price for these drugs is very high, often over $1,000 per month. Insurance coverage for weight loss is improving but can be inconsistent, making access and cost a significant barrier for many patients.
