Can Taking Sugar Cause Diabetes? + 7 Diabetes Myths You Should Stop Believing!

If I had a naira for every time someone said, "Diabetes is caused by eating too much sugar," I’d be richer than Nigeria’s oil reserves.

Yet, this myth persists, along with many others, keeping people confused about what really causes diabetes and how to manage it. As someone who has had to debunk these myths repeatedly on social media, I get it: misinformation spreads faster than wildfire.

But here’s the good news: diabetes isn’t about fear, guilt, or drastic restrictions. It’s about understanding the facts so you can take control without falling for outdated beliefs.

Let’s clear up the confusion once and for all.

1) Myth: "Diabetes is caused by eating too much sugar.

Fact: Diabetes happens when your body struggles with insulin; either it doesn't make enough (Type 1) or can't use it properly (Type 2).

While too much sugar isn't good for anyone, it's this insulin problem, not sugar itself , that causes diabetes. Although excess sugar can contribute to weight gain, excess weight gain can put you at risk of developing type 2 diabetes.

2) Myth: If you’re on medication or insulin, you don’t need to change your lifestyle.

Fact: Medication helps, but diet, physical activity, stress management, and sleep are key parts of long-term control and reducing complications.

3) Myth: People with diabetes can’t eat carbs or sugar at all.

Fact: People with diabetes can eat carbs, including swallows like eba, amala, pounded yam, etc., and even small amounts of sugar. It's all about portion control and balance. Carbohydrates are part of a healthy diet for everyone.

4) Myth: Once you’re diagnosed, you can’t reverse it.

Fact: While type 1 diabetes isn’t reversible, some cases of type 2 diabetes can be reversed or put into remission through lifestyle changes, weight loss, and early medical support.

5) Myth: Bitter foods (bitter leaf, garlic, aloe vera) can cure diabetes.

Fact: While some bitter foods may help support blood sugar control, they do not cure diabetes.

There is no official medical guidance on how much to take or how safe they are, especially when combined with diabetes medications. Using them without professional advice may even cause hypoglycaemia (low blood sugar).

They may have potential as part of diabetes management, but more research is needed, and they should never replace proper medical care.

6) Myth: Only rich/overweight people get diabetes.

Fact: Anyone can get diabetes, regardless of weight, size, or income. While being overweight increases the risk, many people with diabetes are not overweight. Genetics, age, physical inactivity, and diet all play a role.

Also, Type 1 diabetes has nothing to do with weight or lifestyle. It’s an autoimmune condition that can affect both children and adults, even if they’re slim and active.

7) Myth: If you feel fine, your diabetes is controlled.

Fact: Feeling okay doesn’t always mean your blood sugar is okay. Diabetes can silently damage your eyes, kidneys, nerves, and heart, even when you have no symptoms.

The only way to truly know if your diabetes is controlled is by checking your blood sugar regularly and doing routine health checks (like A1C, kidney tests, cholesterol, etc.).

Diabetes is not a death sentence and can be managed with proper care, lifestyle changes, and support. The best way to take control is with the help of a professional.
