How Are Renal Glycosuria And Diabetes Different
2 different things: For reasons we don't understand, sometimes the kidneys may allow some glucose to slip out into the urine even when the blood level of glucose is normal. This can be detected by a urine dipstick test. In diabetes, the blood level of glucose will be high. In some diabetics, the blood glucose gets so high that the sugar spills over into the urine also.See 1 more doctor answer
What is the difference between Renal Glycosuria and Diabetes Mellitus? How to explain relationship between intraversical volume and pressure? Thanks
There are none: Some people's kidneys, by birth or sometimes by medication / toxin effect, simply waste glucose despite the blood sugar being normal. Some glucose is always filtered in the glomeruli, and a few folks have tubules that aren't good at reabsorbing it. When it's genetic, it's perfectly compatible with a lifetime of excellent health.
They are the same: I think that you want the difference between the glycosuria of diabetes mellitus (spilling glucose due to hyperglycemia) and spilling glucose due to the inabilitiy of the kidney to completely reabsorb filtered glucose in someone with euglycemia. The first is high glucose overpowering the reabsorbtion, the second is from weak reabsorbtion. The second is probably harmless, the first is a bad disease.

Myself 48 years, my son 20yrs, daughter 11years are having Renal glycosuria since birth, Myself had taken no treatment since 1984, any treatment now?
No Rx needed, but I: Recommend period screening for diabetes with HgbA1c or 2H PP blood glucose, to ensure that the ongoing glycosuria is not a reflection of diabetes, which would present the same way. Renal glycosuria is influenced by blood sugar levels, so focus on a diet with foods with a low glycemic index instead of simple sugars like pop and juice and stay well hydrated to minimize risk of kidney stones.
Have GTT test. Blood glucose normal. O hour and 1 hour urine glucose negative but 2 hour urine glucose is trace. False positive or renal glycosuria?
Urine glucose: If your GTT is OK and the 2 hour urine only a trace high, I don't think you have anything to worry about. That said, be careful with your food and drink intake.
Can symptoms of nondiabetic renal glycosuria happen only in the evening? (invert sleep cycle too) see nephrologist soon, +ketostix urine=sweet smell
This doesn't add up: Non-diabetic renal glycosuria (i.e., the kidney spills glucose despite normal blood levels) doesn't produce symptoms. Urine odor doesn't reflect glucose levels at all reliably. Ketostix often yield +1 for no reason, or because you're hungry. With dysautonomia and gastroparesis, is there perhaps a misunderstanding, with diabetes a possibility? You have a right to full information.
Disease vs. Symptom: Diabetes is a metabolic disease caused by not producing enough Insulin or developing Insulin resistance. Glycosuria means the presence of glucose in the urine, which occurs either when the glucose levels in the blood are too high (as in diabetes) or when glucose transport mechanism in kidney tubules is congenitally defective (rare condition).See 1 more doctor answer
Too much glucose: Diabetics have a problem getting the glucose from their blood into their tissues. Their lack of Insulin or Insulin resistance causes the glucose that is in the blood stream to keep building up. When the blood goes through the kidney filter if there is a lot of glucose it is 'dumped' with other waste products into the urine glycouria results.See 1 more doctor answer
What is the likelihood that glycosuria would occur in the absence of diabetes? Will glycosuria cause kidney damage? Would a UTI cause glycosuria?
A small minority: Of people will have slight glycosuria, either normally or due to a genetic kidney disorder. It doesn't generally cause damage to the kidney; elevated glucose, however, will damage the kidney and many other organs. Discuss w/your doctor. Glycosuria can increase potential for uti, not the other way around unless your blood sugar increases.See 2 more doctor answers
Kidney capacity: Glucose in the urine occurs when the blood glucose is high and crosses the threshold of kidney capacity to absorb glucose, then glucose leaks in theurine. Normal kidney threshold is about 180 mg/dl. If you have diabetes and there is no glucose in the urine, it suggest that blood glucose is probably less than 180 mg /dl. Again the kidney theshold varies depending on its function.
Went to doctor for flu and she tested my urine and said I has sugar in my urine and called it glucosuria? Scared I might have a precursor for diabetes
Non-specific finding: Glucosuria typically occurs when the blood glucose level exceeds the kidney's ability to reabsorb it. In non-diabetics that is around 180mg/dl. The only way to diagnose diabetes is to have a hemoglobin a1c >6.5%, a fasting serum glucose >126mg/dl or a random serum glucose >200mg/dl. Glucosuria can easily be mis-measured so diabetes is not diagnosed that way. Talk to your dr. About your concern.
Why are proximal tubular cells not affected in chronic renal failure and thereby not causing glucosuria?
Good question: Chronic renal disease is most often caused by damage to the blood vessels or the glomeruli / filters, leaving the proximal tubular cells able to work on however much filtrate is present.
