ABSTRACT
Most women will demonstrate glycosuria at some time during their pregnancy owing to a fall in the renal tubular threshold for glucose. Consequently, glycosuria is not a reliable diagnostic tool for diabetes. Any suspicion of diabetes must be confirmed by blood glucose measurement. About 2–5 percent of pregnant women will have one form of diabetes. The majority (87.5 per cent) will develop gestational diabetes, while 7.5 per cent are type 1, and 5 per cent type 2.
