Glycosuria (Sugar in Urine): Signs, Causes & Remedy 

Measuring the quantity of sugar in your bloodstream is a traditional a part of on a regular basis life with kind 1 or kind 2 diabetes. Measuring the sugar in your urine, nonetheless, is one thing we needs to be doing now and again on the physician’s workplace, too.

On this article, we’ll talk about what “glycosuria” is, what causes it, indicators and signs, and the way it’s handled.

Glycosuria (Sugar in Urine): Signs, Causes & Remedy 

What’s glycosuria?

Glycosuria is a time period to explain the presence of glucose (sugar) in your urine — which will be examined simply with a urine pattern at your subsequent appointment along with your main healthcare workforce. 

Usually, the renal tubes in your kidneys act as a filter to take away extra glucose out of your system earlier than it passes by way of to your urine.

“With regular renal (ie. kidney) perform, as blood flows by way of the kidneys, glucose and different substances are filtered from the fluid portion of the blood,” explains Nationwide Group for Uncommon Illnesses (NORD).


“The filtrate of the blood then strikes by way of a community of canals often called renal tubules, the place a lot of the filtered substances, together with glucose, sodium, and water, are reabsorbed and returned to the bloodstream, whereas sure undesirable substances are eradicated within the urine.” 

It’s regular for a wholesome grownup to excrete some glucose by way of your urine — about 65 milligrams of glucose per day — as a result of whereas your kidneys take up most of the glucose that passes by way of, it can’t take up all of it. 

65 milligrams might sound like rather a lot, however n truth, it’s such a small quantity, that medical know-how can’t even measure it.

When glucose ranges in your urine start rising above this quantity, nonetheless, it signifies an issue — both along with your kidneys or along with your blood sugar.

Let’s take a better take a look at what causes glycosuria.


What causes glycosuria?

For individuals with any kind of diabetes — and particularly girls with diabetes who’re pregnant — having the glucose ranges of your urine examined not less than annually is vital.

There are 4 probably causes of glycosuria in individuals with diabetes:

Excessive blood sugar ranges

When your blood sugar ranges are excessive (both short-term or long-term), the renal tubes in your kidneys merely can’t take up all of that glucose current, so the surplus glucose inevitably passes by way of your urine.

Quick-term, that is the physique taking good care of itself, however it may result in different points, like yeast infections. That glucose encourages the expansion of yeast within the vagina (and fewer widespread, within the penis). 

Whereas a specific amount of yeast is regular, persistently excessive blood sugars will throw this pure yeast stability out of whack and develop into an ongoing drawback till blood sugar ranges come right down to a more healthy degree. 

In an individual whose kidneys are functioning totally and correctly, excessive blood sugar ranges are the one purpose you’d see measurable quantities of glucose in your urine.


Diabetic renal glycosuria

The opposite reason behind glycosuria is the results of impaired renal (kidney) perform. In individuals with regular blood sugar ranges, renal glycosuria is when the renal tubes in your kidneys will not be correctly absorbing glucose.

This is able to be known as “nondiabetic renal glycosuria.”

In individuals with diabetes, nonetheless, it’s almost certainly associated to diabetic kidney illness or “nephropathy.”

The long-term penalties of excessive blood sugar ranges can considerably overwork and harm your kidneys — by damaging the blood vessels and nerve endings within the kidneys and bladder, in addition to your urinary tract. 

Excessive blood sugar ranges additionally severely have an effect on your kidney’s longterm skill to correctly filter your blood. 

Ultimately, the additional stress this places in your kidneys may cause leakage by way of these previously tiny filter holes. Your kidneys then wrestle to filter correctly as a result of different issues — like protein albumin — are capable of get by way of these holes.

“Excessive sugar ranges,” explains the Nationwide Kidney Basis, “also can trigger these vessels to develop into slender and clogged. With out sufficient blood, the kidneys develop into broken and albumin (a kind of protein) passes by way of these filters and leads to the urine the place it shouldn’t be.”



There are a number of diabetes medicines within the class of “SGLT2 inhibitors” that purposefully trigger the kidneys to excrete extra glucose by way of your urine.

Farxiga (dapagliflozin)Frequent side-effects: yeast infections, urinary tract infections, elevated must urinate, again ache, nausea, elevated levels of cholesterol

Invokana (canagliflozin)Frequent side-effects:  yeast infections, urinary tract infections, elevated must urinate, again ache, nausea, elevated levels of cholesterol

Jardiance (empagliflozin)Frequent side-effects: yeast infections, urinary tract infections, elevated must urinate, again ache, nausea, elevated levels of cholesterol

Additionally known as “gliflozins,” these medication work by stopping your kidneys from absorbing the surplus glucose in your system so it may be handed by way of your urine, stopping it from ever coming into your bloodstream. 

Consequently, this inevitably lowers your blood sugar ranges.

Yeast infections are widespread with these medication, too, particularly if blood sugar ranges are extraordinarily excessive (persistently over 250 mg/dL), as a result of it means there’s a vital quantity of sugar passing by way of your urine.

Consuming numerous water whereas taking these medication is vital to be able to assist transport that additional glucose. 


Gestational diabetes

In those that don’t have kind 1 or kind 2 diabetes, glycosuria could be a signal of gestational diabetes

Gestational diabetes is actually excessive blood sugar ranges that develop in a girl throughout being pregnant and return to regular inside a number of weeks or months after the newborn is born.

Gestational diabetes is essentially associated to weight loss program and weight acquire throughout being pregnant and needs to be fastidiously managed with the assist of your obstetrics (OB) and maternal-fetal drugs (MFM) workforce.

Indicators and signs of glycosuria

In an individual with regular blood sugar ranges, there might simply be no indicators or signs of glycosuria. Nonetheless, glycosuria in individuals with diabetes will often embrace signs additionally associated to excessive blood sugar ranges:

  • Excessive thirst 
  • Excessive starvation
  • Dehydration
  • Incontinence (unintended urination)
  • Needing to urinate extra regularly
  • Needing to urinate in the course of the evening
  • Frequent yeast infections


Remedy for glycosuria

Step one in treating glycosuria in individuals with diabetes is addressing excessive blood sugar ranges.

Working along with your healthcare workforce to cut back your blood sugar ranges is essential for all 4 of the causes listed above.

In case your glycosuria is said to diabetic kidney illness, you’ll must work carefully along with your nephrology workforce.

If glycosuria in individuals with diabetes isn’t the results of a medicine, it’s an indication that your blood sugar ranges are very excessive or your kidneys are struggling — and intervention is completely needed.

Ask your physician to incorporate a urinalysis of the glucose in your urine at your subsequent check-up!
