Why does glucose appear in the urine of a diabetic?

Glucose is usually only found in the urine when blood glucose levels are raised due to diabetes. When your blood glucose levels are high enough, glycosuria occurs because your kidneys can’t stop glucose from spilling over from the bloodstream into the urine.

When is glucose excreted in the urine?

When the blood glucose level exceeds about 160–180 mg/dL (8.9-10 mmol/L), the proximal tubule becomes overwhelmed and begins to excrete glucose in the urine. This point is called the renal threshold for glucose (RTG).

How is blood glucose excreted in urine?

With rising blood glucose the reabsorption of filtered glucose in the proximal convoluted tubule increases until a maximum value is reached. Any further increase in blood glucose (and in the resultant glucose load presented to the proximal tubule) results in the excretion of glucose in urine.

What is Glucosuria caused by?

Glycosuria happens when you pass blood sugar (blood glucose) into your urine. Normally, your kidneys absorb blood sugar back into your blood vessels from any liquid that passes through them. With glycosuria, your kidneys may not take enough blood sugar out of your urine before it passes out of your body.

Is glucose in urine an emergency?

In some cases, sugar in the urine may be a symptom of a serious or life-threatening condition that should be evaluated immediately in an emergency setting. These include: Inadequate therapy for diabetes, with severely elevated blood sugar levels. Uncontrolled diabetes, with severely elevated blood sugar levels.

How can I reduce sugar in my urine?

Treatment for glycosuria

1. Reduce the sugar and processed foods in your diet.
2. Eat a diet consisting of mostly whole foods with plenty of vegetables.
3. Reduce carbohydrate consumption to less than 180 grams per day.
4. Drink water and unsweetened beverages instead of soda or juice.
5. Get daily physical activity.
6. Lose weight.

Why does my urine stink?

When urine is highly concentrated, it contains more ammonia and less water. This can cause it to have a strong smell. Urine tends to be more concentrated when a person is dehydrated. This is often the case first thing in the morning or when a person does not drink enough water throughout the day.
