Sub-Threshold Hyperglycemia and Glycuresis.

Folin1 states that “Glycuresis is independent of the level of blood sugar and is not normally obtained from the ingestion of pure glucose.”The opposite view is expressed by Benedict in the following:2 “We note at once that in every instance there is a definite general form to the curve of the sugar elimination following the ingestion of the sugar. The general form of this curve is a rise in the middle and a fall at both ends,” and “ … offers convincing evidence that the experimental factor (glucose ingestion) was responsible for an increased urinary sugar excretion in these experiments.”The experiments reported were designed to compare glycuresis during short intervals, with frequent values for blood sugar for comparison.Thirty-six experiments were performed on 25 human subjects. We have found that the moderate rises in the blood sugar level after the ingestion of either pure glucose or a mixed meal are accompanied by parallel increases in the amount of urinary sugar excreted per hour. With the ingestion ...
