Abstract
The limiting level of hyperglycemia was determined by a 2-dose glucose tolerance technique in 46 diabetic and 15 non-diabetic individuals. In most cases, the 2-dose technique revealed the maximum level of blood sugar which could be attained by oral ingestion of glucose. This, by difinition, is the limiting level of hyperglycemia. A remarkably constant ratio existed between the fasting blood sugar value and the limiting level of hyperglycemia. In both severe and in mild diabetics, as well as in non-diabetics, the ratio of limiting level of hyperglycemia to fasting blood sugar levels fell within the range of 1.6 to 2.3 in 90% of cases.
