Polyuria and Type 1 Diabetes

Type 1 diabetes is an autoimmune disease that causes your pancreas to stop producing insulin, a hormone that is essential to getting energy from food. It strikes people of all ages and is unrelated to diet or lifestyle. People living with this disease must regularly monitor their blood sugar levels, inject or infuse insulin, and carefully regulate doses with eating and activity throughout the day.


What causes frequent urination with diabetes?

Polyuria occurs when your body urinates more frequently—and often in larger amounts—than normal. Frequent urination is also a symptom of undiagnosed type 1 diabetes that can lead to extreme dehydration and eventually affect your kidney function. Polyuria in diabetes occurs when you have excess levels of sugar in the blood. Normally, when your kidneys create urine, they reabsorb all of the sugar and direct it back to the bloodstream. With type 1 diabetes, excess glucose ends up in the urine, where it pulls more water and results in more urine.

What should I do if I think I’m experiencing type 1 diabetes-related polyuria?

If you find you are suddenly urinating more frequently—especially if it’s accompanied by other symptoms—it’s important to see your doctor. As we mentioned above the dehydration that results from polyuria, or excessive urination, can lead to kidney problems—or even diabetic ketoacidosis, which can be life-threatening.
