Why I Urinate Frequently at Night

2013-01-19 17:34

frequent urinationChronic renal failure patients will have increased urine output and the frequency of urination will also increase especially frequent urination at nights. This will severely affect patients’ sleep quality and it has bothered a lot of patients especially the elderly patients.

Here I will tell you why renal failure patients will urinate frequently at night.

Usually when GFR reduces to 10%-25% and creatinine is elevated to 450-707, there will be obvious increased night urination and at the same time there will be anemia, water and electrolyte disorder, blood in urine and bubbles in urine.

Under normal circumstances, urine output at night is less than that during the daytime because of low metabolism and slow blood flow at nights.

However if there is frequent urination at night (more than 2 times) and much increased night urine output and this condition lasts for a long time, it usually indicates kidney problems.

In case of many kidney diseases---glomerular diseases, chronic tubular interstitial diseases, the first symptom and sign will be frequent night urination due to declined renal function of concentration. High blood pressure and diabetes are common factors that can damage renal concentration function and cause frequent night urination and increased night urine output.

Another reason is that the damaged kidney can not discharge all the metabolic wastes and toxins during the daytime and the kidneys have to work at nights to discharged the remaining wasteful products. This will also cause increased night urination.

Of cause frequent urination at night is not definitely related to kidney problems. The following are some conditions that need to be first ruled out.

Drinking large amount of water before sleep or drinking strong tea, coffee or taking diuretics.

Mental factors such as high nervousness can cause frequent night urination, but usually the volume does not increase.

Cardiac insufficiency or endocrine disease such as chronic adrenal insufficiency can also cause frequent urinating at night.

However if the frequent night urination is confirmed to be caused by renal disease, you are recommended to go to local kidney disease hospital and seek professional and early treatment.
