Hypoglycemia And Glucose Levels In Blood

Jun 21, 2008
Hypoglycemia happens if your blood glucose drops too low. It can come on fast. Hypoglycemia is not a disease.

Symptoms of low blood glucose include weakness, hunger, sweating, and feeling nervous or restless. If you develop these symptoms during the test, you may have your sugar level checked quickly with a glucose meter. Symptoms of hypoglycemia may not be obvious in newborn babies. The following are the most common symptoms of hypoglycemia.

Blood glucose may be measured on a fasting basis (collected after an 8 to 10 hour fast), randomly (anytime), post prandial (after a meal), and/or as part of an oral glucose tolerance test (OGTT / GTT). An OGTT is a series of blood glucose tests.

Blood glucose monitors have been found to be accurate and reliable if correctly used, and most monitors provide results within two minutes. Some glucose monitors can also give verbal testing instructions and verbal test results for people who are visually or physically impaired. Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection. This test may predict the development of type 1 diabetes in some patients.

Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection. This test may predict the development of type 1 diabetes in some patients. Blood glucose levels that vary widely may indicate a problem. This test is also called a casual blood glucose test. Blood glucose is the body's major fuel for the energy it needs. When insulin is absent or ineffective, the blood glucose level increases.

Diabetes and its complications are major causes of morbidity and mortality in the United States and contribute substantially to health-care costs. However, these surveys rely only on self-reports of previously diagnosed diabetes and cannot measure the prevalence of undiagnosed diabetes. Diabetes must be confirmed with a blood test. In one test, glucose is given to the patient in a beverage, after which blood samples are drawn and tested at intervals.

Glucose concentrations in sodium fluoride samples are consequently lower than in promptly separated serum samples (by approximately 7-12%). Glucose-galactose malabsorption generally becomes apparent in the first few weeks of a baby's life. Affected infants experience severe diarrhea resulting in life-threatening dehydration, increased acidity of the blood and tissues (acidosis), and weight loss when fed breast milk or regular infant formulas.

Glucose is critical in the production of proteins and in lipid metabolism. Also, in plants and most animals, it is a precursor for vitamin C (ascorbic acid) production.

Glucose is carried to each cell through the bloodstream. Cells, however, cannot use glucose without the help of insulin . Glucose is a normal constituent of the blood of animals ( see Sugar Metabolism ).

Glucose is absorbed from the gastrointestinal tract directly and is also derived from digestion of other dietary carbohydrates. It is also produced inside cells by the processes of glycogen breakdown (glycogenolysis) and reverse glycolysis (gluconeogenesis).
