What Does A Blood Glucose Meter Do?

Glucose Meter

Four generations of blood glucose meter, c. 1993–2005. Sample sizes vary from 30 to 0.3 μl. Test times vary from 5 seconds to 2 minutes (modern meters typically provide results in 5 seconds). A glucose meter is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart. It is a key element of home blood glucose monitoring (HBGM) by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained by pricking the skin with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. The meter then displays the level in units of mg/dl or mmol/l. Since approximately 1980, a primary goal of the management of type 1 diabetes and type 2 diabetes mellitus has been achieving closer-to-normal levels of glucose in the blood for as much of the time as possible, guided by HBGM several times a day. The benefits include a reduction in the occurrence rate and severity of long-term complications from hyperglycemia as well as a reduction in the short-term, potentially life-threatening complications of hyp Continue reading >>

    While it's important to have glucose tablets, orange juice or some other type of sugar handy just in case you "overdose" on insulin you need to know that if you are on insulin you should also have a glucagon kit. If you suddenly go into hypoglycemia and pass out, there would be no way anyone could or should administer anything to you by mouth. An unconscious person would literally choke to death if any type of candy or even liquid were administered. However, that unconscious person could also die because of hypoglycemia! That's why a person who is on insulin should/must have a glucagon kit. The kit is available only by prescription and it is costly…anywhere from $75 to $200 but then again what is your life worth.
    The glucagon kit is very simple to use and comes with detailed instructions clearly printed on the case. Anyone with a diabetic who goes into a hypoglycemic unconscious state can access the glucagon kit, read the instructions and give the unconscious diabetic an injection. The glucagon is a natural hormone with no side affects. Within a few seconds to minutes the diabetic regains consciousness. After regaining consciousness, the diabetic should then take in some type of glucose preferably in the form of a glucose tablet. Then they should check their blood sugars. If it does not come up to at least 75 or 80, they should get to a doctor or E.R. immediately - however they should not drive themselves.
    Ask your doctor, ask your pharmacist. Find out about glucagon kits aka lifesaving kits. :)

    If you inject too much insulin, you start feeling shaky, sweaty, can't think clearly, start to slur your words and may eventually lose consciousness because your blood sugar will drop too low (hypoglycemia). Different people feel low blood sugar effects at different readings. I don't really feel it until my BG drops into the low 50's…luckily that no longer happens so often since I'm now on an insulin pump. To counteract low BG, you need to eat a fast-acting carb like glucose tablets, glucose gel, OJ, apple juice, hard candies like Lifesavers, raisins or just sugar dissolved in water. If you fail to treat a seriously low BG, you'll lose consciousness and may die. Do you remember Sunny VonBulow? She was an heiress whose husband was accused of giving her insulin in an attempt to kill her. The movie "Reversal of Fortune" was made about this case.
    The key is to balance the food you eat, your activity level, and the insulin you take…not always easy but essential.
