Here's how it should ideally work,
You eat food. On digestion, glucose from the food gets into your bloodstream. Your pancreas makes a hormone called insulin. Insulin helps the glucose get into the body's cells so that your body gets the energy it needs.
But if someone has diabetes, the body either
- Cannot make insulin (Type I Diabetes), or
- Insulin doesn't work in the body as it should (Type II Diabetes)
Hence, glucose does not enter cells normally and the blood-sugar level goes up!
High sugar in blood can make people sick if they do not manage or take treatment for it.
Diabetes is a metabolic disorder and people need to detect it as early as possible because high sugar levels due to diabetes can cause a lot of harm to the body and several vital organs.
Blood Sugar Values
Normal Blood Sugar - 70-110 Fasting, less than 140 after 2 hours of eating
Pre-Diabetic Blood Sugar - 100-125 Fasting, 140-200 after 2 hours of eating
Diabetic’s Blood Sugar - over 125 Fasting, 200 or above after 2 hours of eating
Myth: Eating too much sugar will cause diabetes.
Truth: Wrong! For a normal person eating too much of sugar will not cause diabetes but people who already have diabetes should not eat sugar.
But yes, having a lot of sugar is not recommended for everyone as it is high calorie and will lead to weight gain.
