The body also learns to use blood glucose more efficiently when you exercise.

Disruptions in this process can lead to hypoglycemia.
Things like skipping a meal or overdoing your exercise can cause your blood sugar levels to plummet.

This group tends to have higher blood sugar levels (hyperglycemia).
Some of the most concerning hypoglycemic episodes are the ones that occur without your knowledge.
When hypoglycemia occurs while sleeping, blood sugar levels remain low and without treatment.
After a meal, a normal blood sugar level rises to below 180 mg/dL.
These may include:
Aglucagoninjection is mainly used in severe cases of hypoglycemia.
For diabetic children, emergency supplies can be kept in the school nurses office.
