Hypoglycemia is the presence of low levels of sugar in the blood, sugar is the main source of energy in the body, and the reasons for the decline in sugar, including what is linked to drugs used in the treatment of diabetes, and what is not linked Diabetes.

Hypoglycemia occurs as a result of an imbalance between glucagon and insulin. Insulin is the hormone that helps the body take advantage of glucose or sugar in food to supply the body with energy or to store glucose until it is needed, and regulates sugar levels within normal limits. Glucagon is an opposite hormone in its insulin function, which is produced as a reaction when sugar falls in the body, and in cases where the body needs larger amounts of sugar, such as vigorous exercise.

When sugar drops to about 80 mg /dL in the blood, the level of insulin decreases to the point of preventing hypoglycemia, but when the sugar level is lower, glucagon, the body’s first line of defense against hypoglycemia.
