Why Blood Sugar Stays High Without Sweets or Sugar
Blood sugar is the amount of glucose in your blood.
It can be high even if you have not eaten sweets.
Avoiding sugary drinks may not always lower it right away.
This is because blood sugar is affected by more than the sugar in food.
Your body can make glucose on its own.
It can also release glucose when you have not eaten for several hours.
That means high blood sugar does not always come from recently eating something sweet.
Experts say the body’s natural glucose production helps explain this surprising result.
Blood sugar can remain unexpectedly high even when sweets are avoided.
Avoiding sugary drinks does not necessarily prevent elevated blood glucose.
Blood glucose is affected by more than the amount of sugar consumed.
The body can produce and release glucose even when no food is being eaten.
