Sugar in Urine


When sugar in urine is detected in laboratory tests, most would automatically conclude that the person has diabetes. In a lot of cases, this is true; however, there are instances wherein the sugar in urine is not caused by diabetes. One of the functions of the kidneys is to reabsorb glucose or sugar into the body. If the sugar level exceeds the normal limit which is 140mg/dl and shoots up to 180mg/dl or even higher, the kidneys would then expel the excess sugar from the body through the urine. To confirm the underlying cause of sugar in urine, further tests should be conducted.

Diabetes-Causes of Sugar in Urine

The most common cause of sugar in urine is because of the excessive amount of glucose or sugar in the blood. One of the primary functions of the kidney is to filter the sugar and reabsorb it back to the body as the body needs the sugar for energy. However, if there is an abnormally high amount of sugar in the blood, the excess glucose permeates into the kidney and is excreted in the urine.

It should be kept in mind, however, that sugar in urine does not always mean diabetes. Further diagnostic tests like complete blood count should be done in order to confirm the disease.

Other Possible Causes of Sugar in Urine

Sugar in urine does not automatically mean diabetes. Below is the list of possible causes as to why sugar can be detected in the urine:

Renal Glycosuria – It may be Renal glycosuria when sugar is found in urine during urinalysis but the complete blood count shows normal levels of sugar. This happens because of the possible damage of the renal tubules of the kidneys. The renal tubules consist of the nephrons which serve as filters and also function to reabsorb glucose back to the body.

Nephrotic syndrome – Nephrotic syndrome is a condition wherein there is damage to the kidney’s filtering system. This causes albumin or protein and sugar to leak to the kidneys and be excreted through the urine.

Kidney transplant – If an individual just had a kidney transplant, it is possible to find sugar in urine in the first few weeks after surgery as the new kidney is still adjusting. After a few weeks, the urine would be hopefully normal. Proper and constant monitoring should be given to the individual who just had a kidney transplant.

Prediabetes – Prediabetes is a condition wherein the level of glucose has exceeded the normal level in the blood but not yet high enough for it to be diagnosed as diabetes. The excess glucose passes through the kidneys and excreted in the urine. Individuals with this condition should immediately seek medical advice on how to prevent diabetes from happening.

Sugar in urine during pregnancy is also very common. It may be alarming however, it is important to stay calm and not to jump into conclusion. The best person to consult about this is the doctor.
