Nocturnal polyuria may be a kidney disease.
There are two kinds of nocturia: physiologic and pathologic. Physiologic is seen in drinking a lot of water before going to bed, eating food with high water content, taking diuretics and so on, and this kind of situation does not belong to kidney disease.
Pathologic is seen in chronic renal failure. Chronic renal failure is the common outcome of various chronic kidney diseases that continue to progress to the late stage. It is a clinical syndrome characterized by metabolite retention, imbalance of water, electrolyte and acid-base balance, and systemic symptoms, which may result in excessive nocturia. Excessive nocturia may be a kidney disease.
Patients with excessive nocturia should go to the hospital in time to improve the urine routine, bacterial culture, drug sensitivity test, urological ultrasound, bladder residual urine ultrasound, urodynamics and other tests under the guidance of a professional physician to clarify the cause of the disease and timely treatment.
