How Many Times Is It Normal to Wake Up at Night to Urinate? Doctors Explain by Age

Swelling in the ankles or legs

 

Chest discomfort or shortness of breath

In diabetes, for example, excess sugar in the blood pulls more water into the urine, increasing nighttime urination and thirst. In heart conditions, fluid may shift back into circulation when lying down, leading to increased urine production at night.

 

Other Contributing Factors
Doctors also point out that nocturia can be influenced by:

 

Stress and anxiety

Overactive bladder
