glycosuria 2.
Emotional glycosuria
3. Glycosuria in pregnancy 4. Lactating glycosuria
289 . Explain emotional glycosuria .
Answer : Transient hyperglycemia causing
glycosuria may follow emotional factors like fear, anger and anxiety.
290 . What is the reason for renal glycosuria?
Answer : The defect in the
renal tubular enzyme mechanism which is responsible for reabsorption of
glucose. Deficiency of the enzyme causes impairment in the capacity to
reabsorb glucose from the
filtered urine.
