Renal glycosuria is a rare condition in which the simple sugar glucose is excreted in the urine [1] despite normal or low blood glucose levels. With normal kidney (renal) function, glucose is excreted in the urine only when there are abnormally elevated levels of glucose in the blood.
This point is called the renal threshold for glucose (RTG). [5] Some people, especially children and pregnant women, may have a low RTG (less than ~7 mmol/L [5] glucose in blood to have glucosuria). If the RTG is so low that even normal blood glucose levels produce the condition, it is referred to as renal glycosuria.
Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glycosuria. This is associated with diabetes mellitus. [1]
The leading cause of hyperglycemia in type 2 diabetes is the failure of insulin to suppress glucose production by glycolysis and gluconeogenesis due to insulin resistance. [39] Insulin normally inhibits glycogenolysis, but fails to do so in a condition of insulin resistance, resulting in increased glucose production. [ 40 ]
The causes of macroscopic hematuria are similar, but in the absence of an obvious explanation such as trauma or UTI, it is more strongly associated with malignancy and requires further investigation. [101] [147] Elevated levels of protein in the urine are often suggestive of kidney disease, but may have other causes.
Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [ 2 ] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests.
Fanconi syndrome or Fanconi's syndrome (English: / f ɑː n ˈ k oʊ n i /, / f æ n-/) is a syndrome of inadequate reabsorption in the proximal renal tubules [1] of the kidney.The syndrome can be caused by various underlying congenital or acquired diseases, by toxicity (for example, from toxic heavy metals), or by adverse drug reactions. [2]
In physiology, the renal threshold is the concentration of a substance dissolved in the blood above which the kidneys begin to remove it into the urine. When the renal threshold of a substance is exceeded, reabsorption of the substance by the proximal convoluted tubule is incomplete; consequently, part of the substance remains in the urine.
