Who Should Take a GLP-1 Medication — and Is It Only for Diabetes?

GLP-1 medications have become so closely associated with weight loss that it can be easy to forget where they started. Drugs in this category were first used to treat type 2 diabetes, helping people manage their blood sugar. Today, certain medications in this class are also approved for weight management and sleep apnea treatment, including for people who don’t have diabetes.

So, no, you don’t need to have diabetes to take a GLP-1. But that doesn’t mean these medications are right for everyone who wants to lose weight.

Who might be a candidate?

For weight management, prescription medications may be considered for adults with a body mass index, or BMI, of 30 or higher. They may also be appropriate for adults with a BMI of 27 or higher who have a weight-related health condition, such as high blood pressure, high cholesterol, or type 2 diabetes.

Those numbers are a starting point, not the whole story.

When I talk with someone about whether medication makes sense, I want to know much more than their BMI. What have they tried before? Do they have other health concerns? What medications are they taking? Have they repeatedly lost weight only to regain it?

Many factors influence weight, and sometimes eating differently and exercising more aren’t enough to produce meaningful, lasting results.

What does a GLP-1 actually do?

One reason these medications can be effective is that they affect some of the biological signals involved in hunger and fullness. They can reduce appetite, help you feel full sooner and slow the rate at which food leaves your stomach. Some also help regulate blood sugar.

For someone who has spent years feeling hungry despite trying to eat less, that change can be significant.

But I don’t want patients to think of a GLP-1 as a medication that does all the work for them. I see it as one tool that can make it easier to build and maintain healthier habits.

What if you just want to lose 10 pounds?

This is an important distinction. GLP-1s aren’t intended as a quick way to lose a few pounds before a wedding, vacation, or other event. They’re prescription medications used to treat chronic health conditions, and they come with potential side effects and risks.

The question isn’t simply, “Will this help me lose weight?” It's also, “Is there a medical reason for me to take it, and does the potential benefit outweigh the risk?”

That’s a conversation to have with a healthcare provider who knows your health history.

Who shouldn’t take one?

There isn’t one answer that applies to everyone. Your provider needs to review your medical history, medications, and individual risk factors before prescribing a GLP-1.

Certain health conditions, pregnancy, or plans for pregnancy, and some personal or family medical histories can affect whether a particular medication is appropriate. That’s also why getting these medications through appropriate medical care — rather than treating them as a do-it-yourself weight-loss solution — matters.

What happens after you start?

Starting the medication isn't the finish line.

I encourage patients to use the time they're taking a GLP-1 to build habits that support their health, regardless of what happens with the medication. That means getting good nutrition , maintaining muscle through strength training, staying active, sleeping well and finding an eating pattern they can realistically continue.

Follow-up matters, too. Your provider can see how you're responding, help manage side effects and adjust your treatment when needed.

And it's worth talking about the long term from the beginning. Some people may need ongoing treatment, and weight regain can occur after stopping a GLP-1. You should understand that possibility before you start, not after.

So, should you take a GLP-1?

Maybe. And that’s actually the point.

You don't need diabetes to benefit from certain GLP-1 medications, and you don’t need to figure out on your own whether you qualify. If your weight is affecting your health or you’ve struggled to achieve lasting results with other approaches, talk with your healthcare provider.

A GLP-1 may be one option. It may not be the best one for you. Either way, the goal should be the same: finding an approach that improves your health and that you can live with for the long term.
