Diabetes Myths and Treatment Explained
Diabetes Myths and Facts
In this episode of Myths to Medicine, host Ashma Baruwal, MPH, sits down with endocrinologist Pratikshya Thapa, MD, from the University of South Florida to break down what’s really happening behind the scenes: from insulin resistance to modern treatments like continuous glucose monitors.
Your blood sugar may look normal, but is your body actually healthy? Diabetes is no longer just a condition of older adults. It’s showing up earlier, progressing faster, and affecting millions in ways we didn’t fully understand even a decade ago.
If you’ve ever wondered:
- Why is diabetes rising in young people?
- Are sugar substitutes actually better?
- Or if needing insulin means you’ve failed?
This conversation will change how you think about diabetes.
Why is Diabetes Rising in Young People?
One of the most concerning trends today is how early diabetes is appearing. Over the past decade, type 2 diabetes diagnoses in young people have nearly doubled. Even more alarming, prediabetes now affects about 1 in 3 teenagers in the U.S.
So what’s driving this?
Dr. Thapa explains that it’s not just one factor; it’s a combination:
- Ultra-processed diets are high in sugar and refined carbs.
- Sedentary lifestyles. (less movement, more screen time)
- Poor sleep patterns.
- Chronic stress.
- And importantly, genetic predisposition.
We are seeing metabolic disease much earlier, not because the body changed but because our environment did. This shift means that diabetes is no longer something to “worry about later.” Prevention needs to start early, sometimes even in childhood.
What is Insulin Resistance And Why Does It Matter?
To truly understand diabetes, you need to understand one key concept: insulin resistance. Think of insulin as a key. After you eat, your blood sugar rises. Your pancreas releases insulin, which acts like a key: unlocking your cells so glucose can enter and be used for energy.
But in insulin resistance? The key still works, but the lock is jammed. Your cells stop responding properly. Sugar stays in the bloodstream. And your pancreas tries to compensate by producing more insulin.
Over time, this leads to:
- Persistently high blood sugar.
- Increased fat storage.
- And eventually, pancreatic burnout.
By the time blood sugar rises, insulin resistance has often been present for years. This is why early lifestyle changes matter: they target the root problem, not just the numbers.
Common Diabetes Myths (And the Truth You Need to Know)
Misinformation is one of the biggest barriers to good diabetes care. Let’s break down the most common diabetes myths discussed in the podcast.
1. Myth 1: Only Overweight People Get Diabetes
This is one of the most harmful misconceptions. While obesity increases risk, many people with a normal weight develop type 2 diabetes—especially those with:
- Family history.
- Visceral (hidden) fat.
- South Asian or other high-risk ethnic backgrounds.
Weight is part of the story, not the whole story.
2. Myth 2: Honey and Brown Sugar Are Better Than White Sugar
This sounds healthy, but it’s misleading. Your body processes:
- Honey
- Brown sugar
- White sugar
In very similar ways, when it comes to blood sugar spikes. The real issue is total sugar load, not the “type” of sugar.
3. Myth 3: You Must Cut Out All Carbohydrates
Carbs are not the enemy. In fact, your body needs carbohydrates for energy. The key is choosing the right type:
- Whole grains.
- Fiber-rich foods.
- Vegetables.
Refined carbs (white bread, sugary drinks, processed snacks). It’s not about removing carbs—it’s about choosing smarter carbs.
4. Myth 4: Starting Insulin Means You Failed
This myth creates unnecessary guilt and delays treatment. Type 2 diabetes is a progressive condition. Over time, the pancreas produces less insulin.
Needing insulin doesn’t mean failure—it means:
- Your body needs additional support.
- You’re treating the disease appropriately.
Insulin is not a punishment; it’s a tool.
Myth 5: Weight Loss Drugs Can Cure Diabetes
Medications like Ozempic have changed the landscape of diabetes care.
They can:
- Improve blood sugar.
- Support weight loss.
- Reduce cardiovascular risk.
But they do not cure diabetes. What they can do is help patients achieve remission, especially when combined with lifestyle changes.
How is Diabetes Treatment Changing Today?
Diabetes care is evolving rapidly, and this is where things get exciting.
1. Continuous Glucose Monitoring (CGM)
CGMs are one of the biggest breakthroughs in modern diabetes care.
These small wearable devices:
- Track glucose in real-time.
- Show trends. (not just single numbers)
- Help patients understand how food, stress, and sleep affect them.
Instead of guessing, patients can now see what’s happening inside their body live. This has been a game-changer not just for people with diabetes, but also for those with prediabetes and metabolic risk.
2. Personalized Medicine
We are moving away from a “one-size-fits-all” approach.
Now, treatment is tailored based on:
- Individual risk factors.
- Genetics.
- Lifestyle patterns.
- Glucose variability.
3. Focus on Prevention and Early Action
Perhaps the biggest shift? Treating diabetes before it becomes diabetes.
This includes:
- Screening for prediabetes.
- Addressing insulin resistance early.
- Lifestyle-first interventions.
What You Can Do Today (Simple, Practical Steps)?
You don’t need a complete life overhaul to reduce your risk. Start with these high-impact habits:
1. Move More
- Aim for 7,000–10,000 steps per day.
- Add resistance training 2–3 times/week.
2. Eat Smarter
- Focus on whole, unprocessed foods.
- Reduce sugary drinks and refined carbs.
- Increase fiber intake.
3. Sleep Better
- Target 7–8 hours of quality sleep.
- Poor sleep worsens insulin resistance.
4. Know Your Numbers
- Fasting glucose
- HbA1c
- Consider CGM if high-risk
Why This Conversation Matters?
Diabetes is not just about sugar.
It’s about:
- Metabolism
- Hormones
- Lifestyle
- And long-term health risks like heart disease
The earlier we understand it, the more power we have to change the outcome.
Diabetes doesn’t start the day you’re diagnosed; it starts years earlier.
Frequently Asked Questions
1. What are the main types of diabetes?
- Type 1 diabetes: An autoimmune condition where the body doesn’t produce insulin.
- Type 2 diabetes: Driven by insulin resistance and lifestyle/genetic factors.
2. Can type 2 diabetes be prevented?
Yes, many cases of type 2 diabetes can be prevented or delayed through the following:
- Healthy diet
- Regular physical activity
- Weight management
3. Can diabetes be reversed?
While not “cured,” some people can achieve remission with:
- Weight loss
- Lifestyle changes
- Medications when needed
