What is urine and how it is produced ?
Urine is an excretory product produced by the kidneys and is passed through the ureters (tube) into the bladder. When the bladder becomes full, urine is expelled through urethra. When you eat and drink foods, the nutrients present in it are absorbed into the blood and other waste products are sent into the intestine. This would gradually pass into the kidney where urine and stool is produced from the waste food products. The nerve that controls the process of urination is complex and travels widely on your body reaching up to brain and spinal cord.
Normally an adult will require sleep for about 6-8 hours without urinating. But there are many people who get up several times during night for relieving themselves. This process of urinating at night is known as nocturia and there are several factors relating to it.
Diabetes mellitus is one of the major causes which urge you to pass urine frequently at night. Drinking too much of water or any other fluids can induce you to get up many times during night. Caffeine present in coffee or many beverages can trigger producing more of urine by the kidneys.
Some medicines given for depression and anxiety can increase the urination at night. Diuretic drugs given for managing blood pressure can induce you to get up many times. Any other nervous problem like stroke or epileptic medicines can trigger discharge of urine frequently.
If there is tumor in the pelvis or stones in the gall bladder it can cause frequent urination. Enlarged prostate glands and infection in the kidneys, bladder cancer, and cyst formation in the ovary or inflammation of the bladder wall are some of the other factors that increase urine output.
