Could low high blood sugar be making you very tired immediately after you eat?

Answer 1

Yes, both low and high blood sugar may be causing you to feel tired after a meal.
Normally the sugar levels rise after eating, even for non-diabetics.

If the insulin dose is too small, you may reach blood sugar levels that can make you sleepy, grumpy

and thirsty.
On the other hand, if you overcompensate and the insulin dose is too big, the blood levels will rise briefly, then drop abruptly to hypoglicemia.

This may manifest as sudden

exhaustion, confusion and lack of coordination. Other symptoms include cold hands and feet, abundant perspiration and tachycardia (increased heart rate).
As a standard, the blood levels peak at one hour after the meal, but it may differ depending on the individual's

metabolism

, number and type of carbohydrates eaten, activity done after eating and many other factors.

To see what's really happening,

you should test your blood sugar levels at one hour and four hours after the meal, times that

correspond to when the sugar level peaks and when most fast acting insulins

end their action.
