Frequent urination at night is a sign of kidney disease, but not all of them indicate problems on your kidneys. However, a long-term frequency of urination requires your serious attention and need examination and also further treatment.

Frequent urination happens to anyone. The frequency of urination refers to the amount of urine doesn’t exceed 750ml/12hr, and the urination at night is no more than one third of the total. The symptom is closely connected with kidney disease. What’s more, it reports some kind of heart, endocrine disease and other kidney diseases. Normally speaking, this symptom occurs as the following conditions:

It is hard enough to find out the where the problem is by just detecting serum creatinine, urine analysis and ultrasonic B for the time being. This is one reason responsible for the misdiagnosis of Renal Failure or early kidney disease.

Endocrine disease

The typical disease is diabetes or diabetes insipidus. Those patients suffer from increased urine output not only in the daytime, but also at night.

Physiological increased night urination
