Chronic high blood sugar is called diabetes mellitus . This definition of this disease exists throughout the modern world. The fact is that all complications of diabetes mellitus arise due to an increase in blood sugar.
Diabetes and kidney – what is the connection between them?
Human kidneys can be compared to a filter, the task of which is to remove harmful substances from the body and retain useful ones. Until the blood sugar levels are within the normal range, the kidneys do not excrete it into the urine . When it exceeds the norm, “excess” sugar begins to penetrate into the urine, since the kidneys are no longer able to keep it in the blood. But sugar from the body can be excreted only with the liquid in which it is dissolved. That is why thirst appears: glucose, which is excreted in the urine, “carries away” about 15-20 grams of water.
The minimum blood sugar value at which blood sugar begins to enter the urine is called the kidney threshold . This level of renal threshold is different for each person, but on average it is 10 mmol / L. It should not be allowed that glucose, which is vital for the cells of the body , leaves it with urine. You just need to lower blood sugar, thirst will disappear, weight loss will stop, the amount of urine excreted will normalize, efficiency and well-being will improve. This is why it is very important that each patient knows their individual renal threshold level.
With the help of the table, which must be filled in several times, each patient will be able to establish for himself the level of the renal threshold. It will take into account such indicators as the sugar level in 30-minute urine and blood sugar level, which can be measured by such modern devices as glucometers ( CleverChek , OneTouchSelectSimple ).
What is 30-minute urine? The patient needs to empty the bladder. But this urine is not used anywhere. After that, it is necessary to measure the blood sugar level and record the result in the plate (column number 1). Thirty minutes later, the patient should collect a new portion of urine, measure the sugar level in it with the help of test strips ( Glukofan , Uriglyuk , etc.) and enter this indicator in column No. 2. By taking a few measurements, it will be possible to understand at what level of blood sugar it enters the urine.
| Blood sugar , mmol / l | Sugar in urine, % |
| 9,7 | 0.5 |
| 10 | one |
| 9.2 | 0 |
The table shows that with a blood sugar level of 10 mmol / l, urine sugar level is 1%. It follows that the renal threshold has been exceeded. When blood sugar is 9.2 mmol / l, there is no sugar in the urine; from which it follows that the blood sugar level is below the renal threshold. And with a blood sugar of 9.7 mmol / l, glucose appears in the urine (0.5%). Thus, it can be determined that the level of the renal threshold in our example reaches 9.5-9.7 mmol / l.
Care must be taken to ensure that blood sugar does not rise above the kidney threshold.
