it is important to determine if your blood glucose level is within healthy range
also to screen for, diagnose, and monitor hyperglycemia (high blood glucose),
hypoglycemia
Blood glucose: as part of a regular physical, when you have symptoms suggesting
The body’s use of glucose hinges on the availability of insulin, a hormone produced by the
pancreas. Insulin acts as a traffic director, transporting glucose into the body’s cells, directing
the body to store excess glucose as glycogen (for short-term storage) and/or as triglycerides
in adipose (fat) cells. We cannot live without glucose or insulin, and they must be in balance

GLUCOSE ABSORBTION AND REGULATION :
Glucose is a simple sugar that serves as the main source of energy for the body. The carbohydrates we eat are broken down into glucose (and a few other simple sugars),
absorbed by the small intestine, and circulated throughout the body. Most of the body’s cells
require glucose for energy production; brain and nervous system cells not only rely on glucose
for energy, they can only function when glucose levels in the blood remain above a certain

Normally, blood glucose levels rise slightly after a meal, and insulin is secreted to lower them
, with the amount of insulin released matched up with the size and content of the meal. If
blood glucose levels drop too low, such as might occur in between meals or after a strenuous
workout, glucagon (another pancreatic hormone) is secreted to tell the liver to turn some
glycogen back into glucose, raising the blood glucose levels. If the glucose/insulin feedback
mechanism is working properly, the amount of glucose in the blood remains fairly stable. If the
balance is disrupted and glucose levels in the blood rise, then the body tries to restore the
balance, both by increasing insulin production and by excreting glucose in the urine

Severe, acute hyperglycemia or hypoglycemia can be life-threatening, causing
organ failure, brain damage, coma, and, in extreme cases, death. Chronically
high blood glucose levels can cause progressive damage to body organs such
as the kidneys, eyes, heart and blood vessels, and nerves.
Chronic hypoglycemia can lead to brain and nerve damage.

Some women may develop hyperglycemia during pregnancy and this may lead
to gestational diabetes. If untreated, this can cause these mothers to give
birth to large babies who may have low glucose levels.
Women who have had gestational diabetes may or may not go on to develop
diabetes.
