Glycosuria: Definition, Causes, Pregnancy



Glycosuria is a condition in which glucose is present in urine and this amount of glucose will reduce Fehling's solution.

What are the causes of Glucosuria? (Expert Homeopathy: Dr. Anutosh Chakraborty)

Heavy intake of carbohydrates (Alimentary glycosuria)

Stong emotion or excitement, adrenalin injection (Nervous glycosuria)

Injury to the floor of the 4th ventricle of the brain (Piqure glycosuria)

Diabetes mellitus or pancreatic diabetes (Endocrine glycosuria)

Hyperthyroidism (Endocrine glycosuria)

Increased secretion of adrenalin due to sympathetic stimulation, excitement, etc. (Endocrine glycosuria)

Acromegaly due to hyper-secretion of Anterior Pituitary (Endocrine glycosuria)

Renal glycosuria

Phloridzin glycosuria


Acute infective processes

After general anesthesia

In pregnancy

Head injury

Myocardial infarction

Subarachnoid hemorrhage

Increased intracranial tension

Glycosuria in pregnancy (Expert Homeopathy: Dr. Anutosh Chakraborty)

Selective screening of diabetes and random blood glucose for pregnant women is unnecessary and ineffective due to its low sensitivity. False-positive tests outnumber true positives 11:1. The 50-gram oral glucose challenge is a better test. Diabetes test after the blood test is useless. About 50% of pregnant women find diabetes at some point; this is thought to be due to an increased glomerular filtration rate. The renal threshold of glucose varies greatly, and although blood sugar is normal, it may still result in a positive diabetes test result. Daily high intake of ascorbic acid may show false-positive results.

It is recovered automatically after childbirth.

There is no evidence that testing for gestational diabetes before 28 weeks (as a urine test may suggest) changes pregnancy outcomes. Due to low sensitivity and low positive predictive value, screening for gestational diabetes by diabetes is not effective. False-positive tests are 11:1 more than true positive tests, leading to unnecessary further tests. Based on available information, it seems safe to forgo routine urine glucose testing at each prenatal check-up. Regardless of the value of the 50-gram glucose challenge test followed by the oral glucose tolerance test (OGTT) in screening for gestational diabetes is controversial, the recommendation is still valid.
