Bright urine - causes, symptoms and therapy
Our urine consists mostly of water. Only five percent are urea, uric acid, creatinine, salts, acids, dyes, hormones and vitamins. We give off about two liters of urine a day, depending on how much we drink. The more we sweat, the less urine leaves the body.

Kidneys and urethra
The urine is formed in the kidneys and passes through the ureter into the bladder. Out there leads the urethra. When the kidneys become ill, fluid and waste can no longer be excreted as needed. A discolored urine may indicate this.
If the urine appears significantly lighter than usual, this is usually due to increased hydration. However, more serious diseases can be the cause, especially if the urine daurhaft particularly bright. (Image: Björn Wylezich / fotolia.com) The urethritis
The urethra connects the outside world with the urinary tract, kidney, and bladder. Through the excretory organ fungi, viruses, bacteria and single cells can invade and cause inflammation. This manifests itself in a slimy or cloudy discharge and painful urination, as well as an increased urinary urgency without drinking more than usual.
The bubble
The bladder lies on the pelvic floor and collects the urine. With more than 350 milliliters, we feel the urge to urinate, but a healthy bladder also stores up to one liter. The bladder is divided into bladder, bladder neck and bladder. Two ureters connect the bladder to the kidneys, and their waste products enter the bladder with the urine to dispose of them through the urethra. The bubble works like a balloon. When the urine fills it, it becomes a ball. Smooth muscles make them very elastic.
Bladder pain is accompanied by a burning sensation while peeing. If the bladder is inflamed, we feel a strong urinary urgency even with small amounts of urine.
discharge
Fluor vaginalis, the vaginal discharge, is completely normal. It is not urine! The discharge starts in girls before puberty and persists until menopause, during ovulation and pregnancy it is stronger. The body disposes of excess mucus from uterus and cells. Lactic acid bacteria in the effluent keep harmful pathogens away.
Normal discharge is transparent to white, during ovulation it looks glassy. In the period it can turn reddish. If the discharge takes on a brown color, then it shows an altered flora in the vagina. This may be due to a pregnancy, but also to a disease. The most common causes of a brownish discharge are hormone fluctuations or infections, but also changes in the tissue or medication can be considered as triggers.
When the fluid intake is high, the urine appears brighter, but it is noticeably darker when the fluid intake is low. (Image: sebra / fotolia.com) Drinking a lot leads to light color
Light yellow urine is usually not a sign of illness. In healthy people, dark urine is a signal to drink more. Namely, urine gets its color from bile substances that form when red blood cells are broken down. The more we drink, the more water dilutes these dyes. The more we sweat and the less we drink, the darker the urine gets.
Transparent urine
Urine in any color can be murky. This is due either to pus, fibrin, a protein or ground cells. It may be a disease of the kidneys or urinary tract. Occasionally murky urine in young men, however, is quite normal.
The urine becomes almost colorless when we drink a lot. But beware: Even a hormonal disorder, the diabetes insipidus (which has nothing to do with diabetes) leads to the excretion of a large amount of very light urine.
The examination of the urine in the laboratory can provide information about existing diseases, but can also be used to establish a pregnancy or to prove a drug abuse. (Image: Gerhard Seybert / fotolia.com) White dyes
Urine in the color of milk or cream indicates that the urine contains white blood cells, and this is usually indicative of infection of the kidneys and / or urethra.
The staining of urine is often the result of harmless medication or food. After drinking beetroot, for example, the urine turns brownish-red, bearberry is a bearberry, rhizome is lemon-colored and certain yellow tablets have a yolk-yellow color.
Diabetes insipidus centralis
Both forms of diabetes insipidus show up in very light urine. In contrast to healthy people who have drunk a lot, the disease is also noticeable in a constant as well as strong thirst. In diabetes insipidus neurohormonalis, the hormone ADH is poorly produced in the hypothalamus or inadequately transported from the hypothalamus to the posterior pituitary. Other causes are that the pituitary glands do not store or release enough of the hormone. ADH provides a concentrated urine - in this diabetes disorder, too much urine is released too unfocused.
Causes of ADH deficiency include traumatic brain injury, cysts, surgery, inflammation, bleeding, heart attacks or tumors. Such disorders can lead to the disease if they damage the hypthalamus or pituitary gland. Very rarely is also one of the following basic disorders: A Wegener's granulomatosis, a sarcoidosis or histiocystosis X. Even rarer is a genetic disposition, so a familial diabetes insipidus.
Diabetes insipidius has not been adequately researched to this day: in one third of cases, the cause remains unknown.
Diabetes insipidius renalis
This is a rare form of an already rare disease. In contrast to the "classic" diabetes insipidus, this renal variant is derived from the kidney. The hormone ADH is present to a sufficient degree, but the kidney can not form normally concentrated urine. Either the aquaporin channel AQP 2 is damaged and the kidney can not recycle water from the primary urine or the renal tubules have been affected by kidney disease or medications such as lithium. With every diabetes insipidus, the kidneys excrete too much water. If the person does not drink to a high degree, then the sodium concentrates in the blood and there is a hypertonic dehydration, a lack of water in the body. (Dr. Utz Anhalt)
