Essentials on Type 2 Diabetes: Diet, Exercise, GLPs, and Surgery
What comes to mind when hearing the word diabetes?
For many, it sounds like a single condition—something that happens when blood sugar gets too high. But type 2 diabetes is more complex than that, and it’s far more common than most people realize. About one in seven adults in the United States has diabetes, while roughly one in three lives with prediabetes. Even if it doesn’t affect someone directly, chances are it touches a family member or close friend.
This topic hits close to home for many, including myself. Recently a relative reached out after being newly diagnosed. That conversation reminded me how overwhelming those first moments can feel—when questions start piling up about what diabetes really means and how to move forward.
In this week’s episode, I’ll talk about type 2 diabetes—what’s happening inside the body, what treatment looks like today, and how to build a healthier routine that supports long-term well-being. It’s a condition that deserves more attention, not only because it’s so widespread but also because it’s manageable—and sometimes even reversible—with the right approach.
What Exactly Is Type 2 Diabetes—and How Is It Treated?
When people hear the word diabetes, it often sounds like one big condition—but it’s actually more complex than that. There are different types, and today’s focus is on type 2 diabetes, which is the most common form in adults. Unlike type 1 diabetes, where the pancreas completely stops making insulin (usually from a young age), type 2 diabetes is more about the body’s response to insulin changing over time. The body still makes it—but the cells stop “listening.” This is called insulin resistance, and it’s what causes blood sugar levels to creep up slowly, often over years.
Before that happens, there’s what’s known as prediabetes—basically the early warning stage. Blood sugar levels are a little high, but not high enough to be diabetes yet. It’s surprisingly common, especially in people who struggle with weight, and the great thing is that it’s often reversible through lifestyle changes. That’s why catching it early matters so much—it’s the window of time when your body’s still trying to keep up, and you can more easily turn things around.
When it comes to managing type 2 diabetes, the main goal is to keep blood sugar in a healthy range and avoid needing insulin injections for as long as possible. Insulin is life-saving when necessary, but it comes with its own challenges—like frequent monitoring and the risk of low blood sugar. Thankfully, treatment options have come a long way. Metformin is a classic starting point—it helps your body use insulin better and even has some bonus benefits like improving longevity. But the real game-changers are the newer meds like GLP-1 receptor agonists (think Ozempic or Mounjaro) and SGLT2 inhibitors. GLP-1s are usually weekly shots that help lower blood sugar, promote weight loss, and even protect your heart and kidneys. Meanwhile, SGLT2 inhibitors work through the kidneys, helping your body literally flush out extra sugar through urine—pretty cool innovations, right?
Type 2 diabetes might seem overwhelming at first, but it’s something that can be managed—and improved—with the right approach. It’s not only about keeping blood sugar in check but also about supporting the body as a whole—protecting the heart, improving energy, and maintaining long-term health. With a steady routine of healthy habits, the right medication plan, and regular check-ins with a doctor, it’s entirely possible to live well and feel stronger, day by day.
Lifestyle: The Foundation of Type 2 Diabetes Care
Managing type 2 diabetes—or preventing it in the case of prediabetes—really starts with lifestyle. It’s all about the basics: diet, movement, sleep, and stress management. These areas are tightly connected to both blood sugar and weight, which is why type 2 diabetes and obesity often show up together. Some experts even call the overlap “diabesity” because they share the same root causes and treatment strategies.
For most people, the first step is to eat in a way that keeps blood sugar steady. That usually means cutting down on simple carbs and sugars, while focusing more on fibrous foods and complex carbs like whole grains and sweet potatoes. These digest more slowly, helping prevent sharp spikes in blood sugar and supporting both weight loss and better glucose control.
One of the biggest breakthroughs in recent years is the rise of continuous glucose monitors, or CGMs. These small sensors, usually placed on the back of the arm, track blood sugar around the clock and connect to a phone or handheld reader. They give real-time feedback on how food, activity, and even stress affect blood sugar. It’s often eye-opening—foods that seem harmless, like white rice or cherry tomatoes, can cause unexpected spikes. With a CGM, people can see exactly how their body reacts and make choices that fit them, not just a generic diet plan.
CGMs aren’t just for tracking—they’re also a game changer for those on insulin, helping reduce the need for constant finger pricks and even sending alerts when blood sugar drops too low. In the bigger picture, lifestyle is still the foundation of diabetes care. With the right habits, tools, and awareness, it becomes something empowering—an approach that helps people understand their bodies better and take real control of their health.
Protecting the Body Beyond Blood Sugar: A Deeper Look at Type 2 Diabetes
Type 2 diabetes isn’t just about high blood sugar—it’s something that can quietly affect almost every part of the body over time. When blood sugar stays high for too long, it can leave a person feeling tired, sluggish, and just off. But the bigger concern is what happens beneath the surface. Elevated blood sugar can take a toll on the heart, kidneys, nerves, eyes, and even the immune system. Heart disease, in particular, is a major risk—having diabetes actually puts someone at about the same risk for a heart attack as a person who’s already had one.
That’s where exercise comes in. Moving the body regularly is one of the best ways to lower that risk. Even just 30 minutes a day—like a brisk walk—can cut the chance of a heart attack by nearly 40%. And those quick walks after meals? They help the body use up extra glucose, keeping blood sugar from climbing too high. Beyond the physical benefits, regular movement also boosts mood and energy, which makes it one of the simplest yet most powerful habits for managing diabetes.
People with diabetes are more likely to catch infections like the flu, pneumonia, or even COVID-19. Staying up to date on vaccines really matters here—it’s an easy step that goes a long way in preventing complications. Since diabetes often comes with high blood pressure and cholesterol, doctors also tend to be a bit more proactive. They might set tighter blood pressure goals or prescribe a statin to protect against heart attack and stroke.
Keeping up with eye exams and foot checks is another big part of the picture—they help catch early signs of nerve or vision problems before they get serious. And for many people, losing around 15% of body weight can completely change the game. That kind of weight loss can improve blood sugar dramatically and, in some cases, even lead to remission. So while type 2 diabetes might sound complicated, managing it really comes down to consistent habits—moving more, eating well, and taking care of the body in small but steady ways that make a lasting difference.
Bariatric Surgery: A Powerful Option for Type 2 Diabetes Control
The link between excess weight and type 2 diabetes is strong, which is why bariatric surgery has become such a valuable option for many people managing this condition. It’s not just about losing weight—it’s about improving how the body handles blood sugar. In fact, many patients see big changes immediately after surgery, sometimes within the same day, with some no longer needing their diabetes medications.
It’s totally normal to feel hesitant about the idea of surgery, but for many, it can be life-changing. Beyond helping with blood sugar control, bariatric surgery can lower the risk of heart disease and other complications tied to obesity. For some, it becomes the moment where things finally start to shift—better energy, more confidence, and less dependence on medications or constant blood sugar monitoring.
That said, it’s not the right choice for everyone. The best way to know if it’s a good fit is to talk it through with a doctor or bariatric specialist. They can help weigh the pros and cons, look at individual health goals, and make sure all the lifestyle changes that come after surgery feel realistic and sustainable.
Managing type 2 diabetes doesn’t look the same for everyone. But with so many effective options now—whether it’s medication, lifestyle changes, or surgery—there’s real hope for lasting progress. It’s about finding the mix that works best and building a healthier, more balanced life from there.
Type 2 diabetes can feel like a lifelong challenge, but it doesn’t have to define someone’s life. With the right mix of treatment, lifestyle changes, and steady support, it’s possible to take control of blood sugar, protect the body, and feel better day by day.
In this week’s episode, I’ll walk through all of this in more detail—from understanding how diabetes develops to the treatments that are changing the way we approach it today. So if you or someone you care about has been diagnosed with type 2 diabetes or even prediabetes, or you just want to understand it better, give this episode al listen. Tune in to hear practical insights, real stories, and what living well with diabetes truly looks like.
