GLP-1 Drugs Take Spotlight During Diabetes Awareness Month

This November, as Diabetes Awareness Month shines a light on one of the nation’s most widespread chronic illnesses, attention is also turning to a class of medications that’s reshaping how doctors manage not just diabetes, but weight and heart health too. These medications—known as GLP-1 receptor agonists—include well-known names like Ozempic, Wegovy, and Mounjaro. And chances are, if you haven’t heard of them yet, someone you know has.

GLP-1s, short for glucagon-like peptide-1 receptor agonists, were originally developed to lower blood sugar in people with type 2 diabetes. But according to Indiana University Health, doctors quickly noticed a surprising side effect: patients were losing significant amounts of weight, and doing so without the heart risks linked to older weight-loss medications like phentermine. That unexpected bonus triggered a wave of research, development, and eventually, new approvals specifically for weight management.

Wegovy became the first GLP-1 drug officially approved for chronic weight management in 2021, kicking off a public and media frenzy around the class of drugs. Since then, more GLP-1s have been approved for both diabetes and obesity, and researchers are continuing to explore their full potential.

One of the most promising areas of study? Heart health. People with diabetes are about twice as likely to develop heart disease as those without it, making treatments that target both conditions especially valuable. Early findings suggest GLP-1s could reduce cardiovascular risk, offering a two-in-one benefit for patients managing type 2 diabetes.

And the innovation isn’t slowing down. Drug companies are now racing to bring even more advanced GLP-1 treatments to market. According to Reuters, Eli Lilly’s experimental pill, orforglipron, has shown better results than Novo Nordisk’s oral semaglutide in clinical trials—improving both blood sugar control and weight loss. If approved, orforglipron could be the first GLP-1 treatment available in pill form without the need for refrigeration, making it easier to store, ship, and use.

Beyond treating diabetes and obesity, scientists are also studying whether GLP-1s could help prevent diabetes before it starts. A recent study published in the Journal of Diabetology and Metabolic Syndrome looked at nearly 3,000 patients across 12 clinical trials and found that GLP-1 use was linked with the reversal of prediabetes and reduced risk of developing type 2 diabetes in the first place.

Despite the growing evidence of benefits, access to GLP-1s remains uneven. Most insurance plans cover them for diabetes treatment, but not for obesity or prediabetes, which are still often viewed as separate and less urgent health issues—even though both are major risk factors for developing type 2 diabetes. However, change may be on the horizon. Medicare and Medicaid programs have the option to join a new five-year pilot program that would allow off-label coverage of GLP-1s for members who are not yet diagnosed with diabetes but are at high risk.

For now, many patients are turning to their doctors with questions about whether a GLP-1 medication might be right for them. These drugs are not for everyone—they come with potential side effects and are usually prescribed only after other options have been considered. But their rapid rise in popularity reflects a deeper shift in how we understand and treat chronic conditions like diabetes.

What Causes Diabetes—And How You Can Avoid It

Diabetes mellitus, or simply diabetes, is a condition that affects how the body processes blood sugar—also known as glucose. Every time we eat, our food is broken down into nutrients: protein becomes amino acids, fat becomes fatty acids, and carbohydrates turn into glucose, the body’s main source of energy.

Glucose travels through the bloodstream to reach the body’s cells. But there’s a catch: it can’t enter the cells without insulin, a hormone made by the pancreas. Insulin acts like a key, unlocking the door that lets glucose in. When the body doesn’t make enough insulin—or when the cells stop responding to it—glucose builds up in the bloodstream instead of being used for energy. That buildup can damage blood vessels and organs over time, leading to serious complications such as kidney failure, blindness, nerve damage, and even amputations.

There are different types of diabetes, but the most common form in adults is type 2 diabetes. In this condition, the body still produces insulin, but the cells become resistant to it. At first, the body tries to keep up by making more insulin. Eventually, though, it can’t keep pace—and that’s when full type 2 diabetes sets in.

The biggest risk factor for type 2 diabetes is being overweight. Other risk factors include being over the age of 45, having a family history of the disease, high blood pressure, high cholesterol, and living a sedentary lifestyle.

Before diabetes develops, most people go through a stage called prediabetes. This is when blood sugar levels are higher than normal, but not yet high enough to be classified as diabetes. The tricky part? Prediabetes usually doesn’t come with any noticeable symptoms. That’s why many people don’t realize they have it until they visit their doctor and get a blood test. The good news is that prediabetes doesn’t have to lead to diabetes.

In fact, studies show that with simple lifestyle changes—like improving your diet, increasing physical activity, and losing just 5 to 10 percent of your body weight—you can cut your risk of developing type 2 diabetes by up to 60 percent. That means there’s a real chance to stop the disease before it starts.

Even after a diagnosis, diabetes doesn’t have to take over your life. People with diabetes can protect their health by keeping their blood sugar, blood pressure, and cholesterol under control. Doing so can reduce the risk of serious complications, including heart disease, kidney damage, and vision loss, by one-third to one-half.

This American Diabetes Month, take time to learn more about your risk—and take action if needed. Ask your doctor about blood sugar testing, especially if you have any risk factors. If you’re already managing diabetes or prediabetes, know that with the right tools and support, you have the power to protect your health and live well.

As Diabetes Awareness Month encourages early detection, lifestyle changes, and better access to care, the GLP-1 conversation highlights both the promise of new science and the need for updated health policies. Whether for managing blood sugar, supporting weight loss, or protecting the heart, GLP-1s have already changed the lives of millions—and could soon do much more.
