Urine usually contains a very small amount of glucose. Urine of one healthy individual contains approximately less than 0.1% of glucose, which can be detected by regular urine tests. Urine does generally not a large amount of glucose, as kidney reabsorb all filtered glucose and refer to the bloodstream. Glucose are found in the urine only when blood glucose level rises to the point where it exceeds the capacity of the kidneys to eliminate the glucose. There is a renal threshold for glucose and is approximately 160 to 190 mg/dL. If the sugar in the blood glucose level exceeds this threshold, the kidneys are overwhelmed and fail to eliminate glucose efficiently. In such a case, urine can contain a much higher level of glucose. Presence of a high level of glucose in the urine is medically called glycosuria or glycosuria. Glycosuria may indicate certain health conditions which are explained below.The causes of urinary glucose
Glucose in the blood is filtered by the kidney glomeruli. But filtered glucose is reabsorbed by the proximal renal tubular renal and then returned to the bloodstream.This normal process can be disturbed, when blood glucose level is so high that the kidneys fail to eliminate all and therefore glucose, glucose starting to spill in urine .ainsi, conditions that can lead to significantly increase blood glucose levels can lead to glycosuria. Another possible cause of glucose in the urine is the inability of the renal tubules glucose, same reabsorb effectively, when the level of sugar in the blood is normal.
Hyperglycemia, or high blood glucose can be caused by conditions such as diabetes mellitus. The reason why, presence of a high level of glucose in the urine is regarded as a sign of diabetes.In diabetes, the body cells fail to absorb and utilize glucose from the bloodstream, either because of the weakness of insulin or an inability to respond to insulin when result, blood sugar level rises, and sugar or glucose starts to pass in the urine. Along with diabetes, there are certain other conditions that can cause hyperglycemia, then glycosuria. These conditions include syndrome Cushing, thyrotoxicosis and acromegaly.
Sometimes the glycosuria may be associated with benign diseases as a heavy meal or eat a large quantity of food sucrés.Un emotional stress can increase the level of glucose in the blood and urine .Auditives too may cause blood glucose and exceed the level of renal threshold. On the other hand, renal glycosuria is the condition where the kidneys fail to eliminate completely, glucose, even when the level of sugar in the blood is normal. This condition can be associated Fanconi syndrome, Wilson cystinosis, hereditary tyrosinaemia, intoxication disease kidney disorders by heavy metals of Lowe syndrome and interstitial nephritis.
Glucose in the urine during pregnancy
Presence of a small amount of glucose in the urine during pregnancy may be normal.Renal threshold gets reduced during pregnancy, for which a small amount of glucose can spill in the urine.Renal threshold reduced during pregnancy may be associated with an increase in renal flow.However, always high glucose in urine indicates gestational diabetes.Gestational diabetes can cause blood glucose high pregnancy rates.It is a type of diabetes that some women during pregnancy.
Thus, what are some of the possible presence of glucose or sugar urines.La glucose causes in urine is detected using bandelettes.Comme glycosuria may be caused by factors, it can be treated after checking the underlying causes if diabetes is the cause of glycosuria, it can be treated with insulin and way of life and changes of regime alimentaire.Les glycosuria treatment options may vary considerably, depending on causes exactes.donc, if you look at your urine glucose to be always high, then consider to get properly evaluated condition with the help of a doctor.
