After dinner, people tend not to drink or eat something and metabolism as well as blood circulation slows down, so initial urine will be reabsorbed thoroughly in kidney tubules and accordingly urine at night is less than urine in daytime. If urine at night is more than 750mL or the volume of urine in daytime, there must be something worry with reabsorbing of kidney tubules. How to Shrink the Cyst With Polycystic Kidney Disease(PKD)

As Polycystic Kidney Disease develops, the growth of cysts stressed other renal tissues and cause anoxia in kidneys, which provoke renal fibrosis. At the late stages of PKD, fibrous tissues will replace the normal renal tissues, causing glomerulosclerosis and tubulointerstitial fibrosis. During the course of renal fibrosis, reabsorption of kidney tubules will be weakened, making more initial urine be released and increasing volume of urine at last.

Therefore, people with Polycystic Kidney Disease (PKD) should pay more attention to night urine and take early treatment if it is increasing.
