Causes and Treatment of High Sugar in Urine

diabetes is the presence of high levels of sugar, also known as glucose, in the urine. It is normal to have a small amount of sugar in your urine, but in some health conditions, sugar levels can be higher than normal. While diabetes does not require treatment, management of the underlying conditions that cause it may be necessary.

This article explains potential causes of diabetes. It will also cover when to seek medical attention and how to diagnose and treat diabetes.

How does glucose enter the urine

It is normal to have glucose in the blood, and it may also end up in the urine. Small organs called kidneys are responsible for filtering blood and removing waste. The cleaned blood is transferred back into the body. The remaining waste goes to the bladder, which collects urine and releases it when you urinate.

While most of the sugar is reabsorbed by the kidneys and re-entered into the blood, some sugar may remain. This sugar enters the bladder with the rest of the fluid, leaving urine in the body.

Diabetes mellitus occurs when the kidneys do not remove enough sugar before it is excreted in urine. When the sugar level in the urine is greater than 25 mg/dL, it is considered to be glycosuria.


It is normal to have some sugar in your urine. However, glycosuria can occur if the kidneys, which act as filters, do not remove enough glucose from the urine before it leaves the body.

Causes of high glucose levels in the urine

High glucose levels in the urine can be caused by medical conditions, genetic mutations, certain medications, and pregnancy.

Keep in mind that some people with high levels of sugar in their urine do not have any symptoms. Even when caused by a medical condition, high sugar levels in the urine may go undiagnosed until the underlying disease progresses or is detected during normal screening.

Hyperglycemia, Prediabetes, and Diabetes

Diabetes can be caused by high blood sugar, that is, high blood sugar. Prediabetes, which occurs before type 2 diabetes, and long-term conditions marked by high blood sugar levels can also cause diabetes.

Diabetes affects hormones insulin And the body’s ability to store and use sugar for energy. Due to uncontrolled diabetes and high blood sugar levels, the kidneys cannot absorb all the sugar. The kidneys then excrete excess sugar from the body through urine.

While diabetes may not cause symptoms, if you have uncontrolled diabetes or high blood sugar, you may experience other symptoms, such as:

  • excessive thirst
  • fatigue or low energy
  • Frequent infections or slow wound healing
  • frequent urination
  • vision changes
  • tingling in the hands or feet
  • Unexplained weight loss

kidney disease

In chronic kidney disease, when kidney function is lost or after a kidney transplant, people may have high levels of sugar in their urine. Studies have shown that increased release of sugar and some essential minerals in the urine can prevent the progression of chronic kidney disease in some people.

With chronic kidney disease, you may notice other symptoms, such as:

  • swelling of the feet, hands, or ankles
  • shortness of breath
  • Increased need to urinate
  • hard to fall asleep
  • fatigue
  • fever

renal diabetes

In some cases, diabetes can be caused by genetic changes that run in families.This rare genetic disorder is called renal diabetesThis can cause the kidneys to release too much glucose into the urine, even when blood sugar levels are normal or low. This type of diabetes usually does not have any serious symptoms.


certain types of diabetes medications, such as ipagliflozin, which prevents the kidneys from reabsorbing glucose to help lower blood sugar levels. This can lead to diabetes.


About 50% of pregnant individuals may develop diabetes due to hormonal changes and the function of the kidneys during pregnancy. Usually this is not a cause for concern, but should still be discussed with your doctor.

gestational diabetes, or high blood sugar levels during pregnancy, can also cause diabetes. Screening is an important part of antenatal care. Symptoms may include feeling super thirsty and having to urinate more than usual.


Diabetes can be caused by high blood sugar levels, kidney disease, genetic disorders, certain diabetes medications, and pregnancy. While diabetes may not cause symptoms, the underlying conditions that cause it may cause other noticeable symptoms.

When should I seek medical attention about sugar in the urine?

If you think you have sugar in your urine, contact your doctor so they can figure out the underlying cause.

Seek immediate medical attention or call 911 if you or someone you know:

  • Changes in consciousness, which describe how awake and alert someone is
  • Passed out
  • going through chaos
  • Seizures, which may cause involuntary movements and altered consciousness

How is Diabetes Diagnosed?

Glycosuria is diagnosed by testing the sugar levels in the urine. Additional laboratory work may also be performed to look for possible root causes.

home test

Urine glucose testing can be done at home. This is done by collecting a urine sample and measuring glucose levels using small devices called urine dipsticks. The dipstick will change color to indicate the different levels of glucose in the sample.

If you are testing at home, be sure to discuss the results with your healthcare provider. For conditions such as diabetes or chronic kidney disease, early diagnosis is important to help slow its progression.

Healthcare Provider Exams and Testing

To test for diabetes, your healthcare provider may order a urinalysis to check sugar levels. They may also order blood tests to check your blood sugar levels and kidney function.

Prediabetes and diabetes are diagnosed based on:

  • A1C test, which is a blood test that checks average blood sugar levels
  • Fasting blood glucose (FPG) test, a blood test that requires an overnight fast and checks for diabetes
  • An oral glucose tolerance test (OGTT), which asks you to take a special syrupy drink before taking your blood to check your body’s ability to process sugar

The results suggestive of prediabetes are:

  • A1C of 5.7%–6.4%
  • Fasting blood glucose of 100–125 mg/dL
  • OGTT 2-hour blood glucose 140 mg/dL–199 mg/dL

Diabetes is diagnosed as:

  • A1C equal to or greater than 6.5%
  • Fasting blood glucose equal to or greater than 126 mg/dL
  • OGTT 2-hour blood glucose greater than or equal to 200 mg/dL


Diabetes can be tested for with home tests as well as blood or urine tests ordered by your doctor.

What is the prognosis for diabetes?

How you feel about diabetes depends on what may be causing it. If nothing else, symptoms or complications will be rare.

If a medical condition is causing you to have high levels of glucose in your urine, it needs to be monitored by your healthcare provider. Your doctor will create a treatment plan that best suits your needs. If your condition progresses, getting treatment as soon as possible may help reduce the chance of complications.

Keep in mind that certain conditions can lead to serious complications. For example, conditions related to high blood sugar levels can lead to complications such as:

  • worsening vision or vision loss
  • poor wound healing
  • Infections that are difficult to heal
  • Nerve damage in the arms and legs, which can cause weakness, pain, or difficulty with muscle control
  • kidney damage


Glycosuria occurs when the kidneys do not remove enough glucose before excreting it in the urine. This can be caused by medical conditions, genetic mutations, certain medications, and pregnancy.

Diabetes can be diagnosed with urine and blood tests. Your doctor may also order other specific tests based on the underlying underlying condition. Treatment will vary based on each person’s specific needs.

VigorTip words

Diabetes may not cause any concern. If you do have excess sugar in your urine, be sure to talk to your healthcare provider. They can recommend treatment options, as well as lifestyle changes that may help prevent complications.
