Glycosuria is the presence of glucose in the urine, caused by excess glucose in the blood that must be excreted. It can occur due to emotional stress, hyperthyroidism, insulin insufficiency, or pregnancy. More serious causes are thyroid or cortisone hormone abnormalities, growth hormone excess, or diseases like diabetes, meningitis, or peptic ulcers. Renal glycosuria is a rare form where blood glucose is normal but glucose is improperly reabsorbed by kidney tubules. Polyuria is frequent, abnormally large urination that can be caused by caffeine, alcohol, overhydration, or excess salt or glucose intake, and may indicate conditions like diabetes, polycystic kidney disease

2.  Glycosuria is the presence of glucose in the
urine. This is caused by the overabundance
of glucose in the blood, and therefore, must
be excreted through the urine.
 It may occur for the following reasons:
 Emotional stress
 Hyperthyroidism
 Insufficiency of insulin
 Pregnancy

3.  Other more serious causes of Glycosuria are
the following:
 Thyrotoxicosis – elevations in thyroid hormone
levels
 Cushing’s syndrome – overexposure of tissues to
high level cortisone hormone.
 Acromegaly – overabundance of growth hormones
resulting in large body tissues.
 Peptic Ulcers – open sores on the inner lining of
the small intestine, stomach or espophagus
 Meningitis – inflammation of the brain and spinal
cord membrane
 Diabetes

4.  RenalGlycosuria is a rare form of Glycosuria
where glucose is eliminated through the
urine, but the blood glucose levels are
normal to low.
 This usually happens as a sign of improper
function of renal tubules to reabsorb the glucose.
 It is non-life threatening and is hereditary.

5.  Polyuria is a
condition to urinate
frequently in
abnormal large
amounts.
 Common main
causes include:
 Consumption of
caffeine or alcohol.
 Overhydration
 Excessive intake of
salt or glucose

6.  It is important to keep track of the liquid intake,
how often you urinate and how much you weigh.
It may be a sign of the following conditions:
 Diabetes Mellitus and Insipidus
 Polycystic kidney disease
 Sickle cell disease
 Certain tests may be administered at the doctor’s
office to help depict the main cause of polyuria:
 Blood glucose test
 Blood urea nitrogren test
 Creatinine studies
 Urinalysis
