What is hypoglycemia?

What is hypoglycemia? Hypoglycemia is the clinical syndrome that results from low blood sugar. The symptoms of hypoglycemia can vary from person to person, as can the severity. Classically, hypoglycemia is diagnosed by a low blood sugar with symptoms that resolve when the sugar level returns to the normal range. Who is at risk for hypoglycemia? While patients who do not have any metabolic problems can complain of symptoms suggestive of low blood sugar, true hypoglycemia usually occurs in patients being treated for diabetes (type 1 and type 2). Patients with pre-diabetes who have insulin resistance can also have low blood sugars on occasion if their high circulating insulin levels are further challenged by a prolonged period of fasting. There are other rare causes for hypoglycemia, such as insulin producing tumors (insulinomas) and certain medications. These uncommon causes of hypoglycemia will not be discussed in this article, which will primarily focus on the hypoglycemia occurring with diabetes mellitus and its treatment. Despite our advances in the treatment of diabetes, hypoglycemic episodes are often the limiting factor in achieving optimal blood sugar control. In large scale studies looking at tight control in both type 1 and type 2 diabetes, low blood sugars occurred more often in the patients who were managed most intensively. This is important for patients and physicians to recognize, especially as the goal for treating patients with diabetes become tighter blood sugar control. I thought high blood sugar was bad. Why is low blood sugar also bad? The body needs fuel to work. One of its major fuel sources is sugars, which the body gets from what is consumed as either simple sugar or complex carbohydrates. For emergency situations (like prolonged fasting), the body stores a stash of sugar in the liver as glycogen. If this store is needed, the body goes through a biochemical process called gluco-neo-genesis (meaning to "make new sugar") and converts these stores of glycogen to sugar. This b

>.>>>>>>****<<<<<<<<<<< Why is a blood sugar test done? Diabetes mellitus is diagnosed based on a high level of glucose (sugar) in the blood. Blood sugar test, done fasting and 2 hours after breakfast, is used for the diagnosis of diabetes. How is the test done? Fasting blood glucose: In this test, a person is asked to fast overnight, at least 8 hours, and the level of glucose in the blood is then checked. Post prandial (PP) blood glucose: This is tested two hours after having a meal. It serves as a challenge for the body to regulate the blood sugar after a meal. Random blood sugar or glucose test is that which is done at any other time. The blood glucose can also be tested after giving 75 gm glucose by mouth (glucose challenge test). This is useful for detecting borderline diabetes and a condition called "impaired glucose tolerance". Blood glucose tests are also needed for checking the control in diabetes. What are the normal values? Normal fasting plasma glucose levels are less

Hypoglycaemia is a common problem faced by patients taking insulin. Three obvious things that take part are: food intake which increases blood sugar, exercise and drugs which lower the blood sugar. Inter-play between these, controls the blood sugar level. But in addition to these many other factors play role, which are not under our control completely. Most important is absorption of insulin from subcutaneous tissue i.e. site where insulin is injected. Newer insulins have the advantage of being more predictable in absorption from site of injection. Incidence of hypoglycaemia hcan be significantly reduced by the use of these newer insulins. Use of newer basal insulins can also help in reducing hypoglycaemia. Most importantly, regular small and frequent meals, planned physical activity, can help in preventing hypoglycaemia. For nocturnal hypoglycaemia. A snack before sleep can be very useful. A diabetic has to learn to be ready to face and treat hypoglycaemia. Better the blood sugar control; more are the chance
