Which of the following is present normally in the urine of a pregnant women in the third trimester -
Glucose Presence of glucose in urine wizen blood sugar level is within normal limits is called renal glycosuria and is thought to be secondary to low threshold for elimination of glucose by kidneys. "Renal glycosuria occurs frequently during pregnancy" Renal threshold for glucose - During pregnancy --) 155 +- 17 - Non pregnant patients 197 +- 6.5 During pregnancy glycosuria can occur at blood sugar levels as low as 70-100 mg/dl. More on renal glycosuria during pregnancy Renal glycosuria during pregnancy is not completely benign and these women are at risk for preterm delivery and for the development of fetal macrosomia. Most pregnant patients with renal glycosuria have normal kidney and the abnormality disappears after delivery. In some cases renal glycosuria during pregnancy is a manifestation of renal tubular damage secondary to chronic pyelonephritis. These patients frequently develop UTI. Management of Renal Glycosuria during pregnancy a) Perform frequent urine testing to detect asymptomatic bacteriuria 1)) Instructing the patient to have several small meals per day, rather than three large meals to avoid postprandial elevation in blood sugar and glycosuria c) Staying ale for early signs and symptoms of preterm labour Patiens with renal glycosuria loose as much as 100g/day of glucose in the urine. Such large doses decrease the amount of glucose available for their caloric needs and lipolysis is activated to maximum. This causes production of ketones and tendency towards ketoacidosis.
