In recent years, weight loss medications like Ozempic, Wegovy, and others have generated a lot of buzz—and confusion. You may have seen headlines, TikTok testimonials, or even heard stories from friends who’ve shed pounds using these injections. But what’s the real story behind these medications? Are they safe? Effective? And who are they actually meant for?
As a primary care physician, I believe in giving patients accurate, balanced, and practical information. So, let’s break it all down.
What Are Ozempic and Wegovy?
Both Ozempic and Wegovy are brand names for a medication called semaglutide, which was originally developed to treat type 2 diabetes. Ozempic is FDA-approved for diabetes management, while Wegovy is a higher-dose version of semaglutide approved specifically for weight loss in people who are overweight or obese.
They belong to a class of drugs called GLP-1 receptor agonists, which mimic a natural hormone in the body that:
-
Regulates blood sugar
-
Slows down digestion
-
Reduces appetite
-
Increases feelings of fullness
This unique combination of effects leads to significant weight loss, especially when combined with healthy lifestyle changes.
How Do These Medications Work?
GLP-1 receptor agonists like semaglutide work in three major ways:
-
Appetite Suppression
They affect the appetite centers in your brain, making you feel full sooner and for longer. As a result, people naturally eat less without feeling like they’re starving. -
Slowed Gastric Emptying
The medication slows how fast food leaves your stomach. This helps control blood sugar spikes and keeps you feeling satisfied after meals. -
Improved Insulin Sensitivity
For people with insulin resistance or type 2 diabetes, these drugs help the body respond better to insulin, which can further support weight loss.
Who Are These Medications For?
These medications are not for everyone. Wegovy is FDA-approved for adults who:
-
Have a BMI of 30 or higher (obese), or
-
Have a BMI of 27 or higher (overweight) with at least one weight-related health issue, such as high blood pressure, type 2 diabetes, or high cholesterol.
Ozempic, while mainly approved for diabetes, is sometimes prescribed “off-label” for weight loss in similar patients.
They are not recommended for:
-
People with a history of medullary thyroid cancer or multiple endocrine neoplasia
-
Pregnant or breastfeeding women
-
Children under 18 (except under specific guidance)
Benefits of These Medications
-
Significant Weight Loss: Clinical trials have shown average weight loss of 15% or more of body weight with Wegovy when combined with diet and exercise.
-
Blood Sugar Control: Great for those with type 2 diabetes.
-
Reduced Risk of Heart Disease: Losing weight and improving blood sugar and blood pressure can reduce cardiovascular risk.
Potential Side Effects
Like any medication, these drugs come with risks:
-
Common Side Effects:
-
Nausea
-
Vomiting
-
Diarrhea or constipation
-
Fatigue
-
Headache
-
-
Less Common but Serious:
-
Pancreatitis
-
Gallbladder disease
-
Kidney issues
-
Possible thyroid tumors (seen in animal studies)
-
These side effects are more likely during the initial weeks or with higher doses, and they can often be managed by slowly increasing the dose as prescribed.
Myth vs. Reality
Myth: “You can take Ozempic and lose weight effortlessly without changing anything.”
Reality: While these medications can help reduce appetite, they are not magic bullets. Long-term success still relies on healthy habits, such as eating nutritious meals, staying active, sleeping well, and managing stress.

Myth: “You have to take them forever.”
Reality: Some people may stop after reaching their goal, but many regain weight if they stop without continuing lifestyle changes. It’s similar to managing high blood pressure—long-term care may be needed.
Cost and Accessibility
One of the biggest downsides is cost. These medications can be expensive, sometimes over $1,000 per month, and not all insurance plans cover them—especially if you’re taking it for weight loss rather than diabetes.
Tip: Check with your insurance provider and talk to your doctor about possible alternatives or discount programs.
A Primary Care Perspective
As your doctor, I don’t just look at the number on the scale—I look at your whole health picture. Medications like Wegovy or Ozempic may be part of a larger strategy to reduce health risks and improve your quality of life. But they are tools, not solutions in themselves.
Before considering medication, we’ll assess:
-
Your weight history
-
Existing health conditions
-
Current diet, exercise, and stress levels
-
Readiness to make long-term changes
When appropriate, these medications can jump-start progress and offer a new lease on life—but they work best when combined with ongoing support, accountability, and care.

Final Thoughts
Ozempic, Wegovy, and other weight loss medications represent an exciting advancement in obesity care. But they’re not for everyone, and they’re not without risks. If you’re struggling with your weight and feel like you’ve tried everything, don’t be discouraged. Talk to your primary care provider about what’s right for you—whether it’s medication, lifestyle coaching, or a combination of both.
You don’t have to go it alone—and there’s no shame in asking for help.
