Why is fasting blood sugar higher than after eating?

Since your body doesn’t respond to insulin the same as most, your fasting blood sugar reading can go up, even if you follow a strict diet. The boost in sugar is your body’s way of making sure you have enough energy to get up and start the day.

Why is my blood sugar lower after I eat?

It’s likely the result of your body making too much insulin after a large, carb-heavy meal. Scientists aren’t sure why, but sometimes your body continues to release extra insulin even after you’ve digested your meal. This added insulin makes your blood glucose level drop below normal.

Is it normal for blood sugar to drop after not eating?

If you haven’t eaten for several hours and your blood sugar level drops, another hormone from your pancreas signals your liver to break down the stored glycogen and release glucose into your bloodstream. This keeps your blood sugar within a normal range until you eat again.

How does fasting affect your blood sugar levels?

Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood.

Why does my blood sugar go down after eating?

It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that “react” to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.

What’s the difference between fasting blood glucose and low insulin?

Insulin is low — an important difference. As Dr. Naiman recently posted, only testing fasting blood glucose without testing fasting insulin tells you very little. That’s because two people could have exactly that same fasting blood glucose levels and have very different circulating insulin levels.

What should blood sugar be one hour after eating?

A normal fasting glucose is 60 to 100 milligrams per deciliter; your levels should rise no higher than 200 mg/dl one hour after eating and no more than 140 mg/dl two hours after finishing the snack.
