  2. 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. 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. 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. 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. 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
