blood sugar

Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia, Wikipedia.


a sweet carbohydrate of either animal or vegetable origin; the two principal groups are the disaccharides and the monosaccharides.
beet sugar sucrose from sugar beets.
blood sugar
1. glucose occurring in the blood.
2. the amount of glucose in the blood.
cane sugar sucrose from sugar cane.
fruit sugar fructose.
invert sugar a mixture of equal amounts of dextrose and fructose, obtained by hydrolyzing sucrose; used in solution as a parenteral nutrient.

d-glu·cose (G, Glc),

Dextrose; a dextrorotatory monosaccharide (hexose) found in the free state in fruits and other parts of plants, and combined in glucosides, disaccharides (often with fructose in sugars), oligosaccharides, and polysaccharides; it is the product of complete hydrolysis of cellulose, starch, and glycogen. Free glucose also occurs in the blood, where it is a principal energy source for use by body tissues (normal human concentration, 70-110 mg per 100 mL); in diabetes mellitus, it appears in the urine. The epimers of d-glucose are d-allose, d-mannose, d-galactose, and l-idose. Dextrose should not be confused with the l-isomer, which is sinistrose.
Synonym(s): cellohexose

blood sugar

1. Sugar in the form of glucose in the blood.
2. The concentration of glucose in the blood, measured in milligrams of glucose per 100 milliliters of blood. In both senses also called blood glucose.

Blood sugar

The concentration of glucose in the blood.
Mentioned in: Antidiabetic Drugs

blood glucose

(often loosely called 'blood sugar') is obtained by digestion of carbohydrates and by release from liver glycogen, and is taken up by the cells of the organs and tissues for use as an energy substrate. In healthy people, blood glucose concentration is homeo statically controlled within a fairly narrow range; maintenance of the normal level is critical for the function in particular of those tissues with an obligatory demand for glucose (brain, red blood cells, renal cortex, mammary gland and testis). Hormones involved include insulin, tending to lower blood concentration, and glucagon, glucocorticoids, adrenaline and growth hormone, tending to raise it. It seldom falls below about 5 mmol.L-1, even after prolonged fasting, and returns to this value within a couple of hours of the rise that follows a meal. When there is no uptake from the gut, about 8 g glucose per hour can be provided from the liver by breakdown of glycogen stores and by gluconeogenesis. During prolonged exercise glucose output from the liver closely matches the increased requirement, so that the blood concentration falls only when the hepatic glycogen store is depleted, close to exhaustion. See also hyperglycaemia, hypoglycaemia.


A dextrorotatory monosaccharide found in a free form in fruits and other parts of plants, and in combination in glucosides, glycogen, disaccharides, and polysaccharides; chief source of energy in human metabolism, the final product of carbohydrate digestion, and the principal sugar of the blood; insulin is required for the use of glucose by cells; in diabetes mellitus, the level of glucose in the blood is excessive, and it also appears in the urine.
Synonym(s): d-glucose.

Patient discussion about blood sugar

Q. I would like to compare old blood sugar and today´s blood sugar values or level. what is the difference?

A. i'm not sure understand the ask how to do so? what does a difference mean? to compare with your old blood sugar test? others?
i would like to help but i think i'll need a bit more information...

Q. does anyone know the range for childrens blood sugar?

A. The range for children's blood sugar level is quite similar to that of adults, and should be below 126 mg/dl after a 12 hour fast, or under 200 mg/dl on a random testing. 2 following testings that show pathologic results define diabetes.

Q. I have Type II Diabetes, but have regular problems with low blood sugar levels. What should I do? I am an over 60 female who has been diagnosed with Type II Diabetes. I was originally on Metformin, but my doctor discontinued it because I was having severe low blood sugar levels a lot (as low as 40). I have heard that putting me on insulin might help, but I don't see how since I have more low than high levels. Anyone have any suggestions or information about what I can do? (I do follow diabetic eating with proper food and frequent small meals, but that doesn't seem to help.)

A. i'm not sure about this but maybe because of your sensitivity to Metformin they want to move to insulin shots because they want accuracy. but as all it sounds a bit strange, cause most of the times they save that as a last resort. there's probably something else that's missing asked them why insulin shots?
