Blood sugar, or blood glucose, plays a vital role in keeping our bodies running smoothly. It’s our energy source and an essential part of our overall health. It’s also something that’s easy to be confused about because there’s so much conflicting information out there. Let’s clear up some common misconceptions to leave you feeling both more informed and more empowered to take charge of your glucose health.

Myth 1: Eating sugar causes type 2 diabetes

Eating sugar by itself doesn’t cause diabetes. Type 2 diabetes is a complex condition influenced by genetics, lifestyle, and other factors. While eating too much sugar can contribute to weight gain (which may increase the risk of type 2 diabetes), it’s not the sole cause. So, enjoy that occasional sweet treat guilt-free—it’s about balance, not blame.

Myth 2: Only overweight people get diabetes

Diabetes doesn’t discriminate. While being overweight is a risk factor for type 2 diabetes, people of any size or weight can develop it. Other factors like family history, age, ethnicity, and activity level also play important roles. As for type 1 diabetes, it’s an autoimmune condition completely unrelated to weight.

Myth 3: People living with diabetes can’t eat sweets

You can enjoy sweets if you’re living with diabetes. The key is moderation and balance. Pair that slice of cake with other healthy choices, track your glucose, and enjoy. It’s all about finding what works for you and sticking to it.

Myth 4: Type 2 diabetes isn’t a serious condition

It’s serious, but it’s also manageable. Without proper care, it can lead to complications like heart disease or kidney damage. But by taking actionable steps, such as making healthy food choices and incorporating movement into your daily routine, people living with type 2 diabetes can live a full and vibrant life.

Myth 5: You can always feel when your glucose is high or low

Glucose levels can be sneaky. Sometimes, they can be too high or too low without obvious symptoms. That’s why regular tracking with a glucose biosensor like Stelo is so helpful—it helps you understand what’s going on inside your body so that you can create healthy habits and stay on top of your health, even when you feel fine.

Myth 6: All sugars are bad for you

Not all sugars are created equal. Natural sugars, like those in fruits, come with added benefits like fiber and vitamins, whereas added sugars in soda or candy don’t provide any nutritional value.

Myth 7: Type 2 diabetes can’t be prevented

While genetics does play a role, there’s plenty you can do to reduce your risk. Staying active, making healthy nutrition choices, and maintaining a healthy weight are all powerful tools. Small, consistent changes can make a big difference.

Myth 8: People with diabetes should avoid carbs

Carbs aren’t the enemy. In fact, they’re a necessary part of a balanced diet. The trick is choosing the right types and amounts. Whole grains, fruits, and vegetables are great options because they release glucose more slowly into your bloodstream, which provides steady energy while preventing sudden glucose spikes. Work with your healthcare team to find what works best for you.

Myth 9: People with diabetes can’t exercise

Actually, physical activity is one of the best ways to manage diabetes. Whether it’s walking around the block, working in the yard, riding your bike, or going to the gym, staying active can help regulate blood sugar and boost your overall health.

Myth 10: Diabetes only affects older people

As we age our risk of developing type 2 does increase. However, most new diagnoses occur between ages 45-65, which is considered middle aged. Since type 2 diabetes can affect anyone, regardless of age, awareness of type 2 diabetes risk factors and symptoms are important for everyone.

Living your best life

Managing your glucose health can feel tricky at times, but remember—small, consistent steps can make a big difference. You can enjoy delicious food, including carbs and the occasional indulgence in your favorite sweets, as long as you find the right balance that works for you. The key is staying mindful: tracking your glucose levels regularly, staying active in ways you enjoy, and choosing nourishing foods. When in doubt, never hesitate to reach out to your healthcare provider—they’re there to support you every step of the way.
