Urea is a metabolic waste product that accumulates in the body in the setting of chronic kidney disease. It is routinely measured on blood tests as a marker of kidney function (higher urea levels indicate lower kidney function).
Urea is manufactured synthetically by reacting natural gas, atmospheric nitrogen and water together at high temperature and pressure to produce ammonia and carbon dioxide. These gases are then reacted at high temperature and pressure to produce molten (liquid) urea.
Your knowledge about urea might be that it comes from urine- which is true. The body produces it as an organic, waste compound after metabolizing protein in the liver. Urea is then excreted by the kidneys through urine. It is also excreted through sweat.
Urea is the chief nitrogenous waste, which is eliminated through urine. Urea is produced in the liver from ammonia, which is a metabolite of amino acids and carbon dioxide. Urine is formed by the nephrons after filtration, secretion and reabsorption.
High levels of urea in the urine may suggest: too much protein in the diet. excessive protein breakdown in the body.
The most common color of urine is yellow, which is caused by the presence of urobilin , a biochemical waste product generated from the breakdown of old red blood cells. (Your body makes about 2 million new red blood cells every day, and recycles an equal number of old ones.)
For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.
If a person experiences clear urine, they do not usually need to take any further action. Clear urine is a sign of good hydration and a healthy urinary tract. However, if they consistently notice clear urine and also have extreme or unusual thirst, it is best to speak to a doctor.
The most optimal color for your urine is a pale yellow. If it is a darker yellow or orange, it can mean you are becoming dehydrated. An orange urine could indicate a serious liver condition. Darker brown can be caused by foods or medication.
If your urine is orange or dark yellow, it's probably because you aren't well hydrated. This means you aren't drinking enough water or getting fluids from other sources. Because you don't drink while asleep, you may notice your urine is darker in the morning.
Despite its alarming appearance, red urine isn't necessarily serious. Red or pink urine can be caused by: Blood. Factors that can cause urinary blood (hematuria) include urinary tract infections, an enlarged prostate, cancerous and noncancerous tumors, kidney cysts, long-distance running, and kidney or bladder stones.
The bottom line. If you notice white particles in your urine, it's likely from genital discharge or a problem in your urinary tract, such as kidney stones or possible infection. If you have significant symptoms that accompany the white particles in your urine, you may want to see your doctor.
If your pee is crystal clear, you're probably drinking too much H20, which can throw off your electrolyte balance in potentially harmful ways. “Your body can normally regulate its water and sodium levels pretty well,” Moore says.
Infections. In more severe cases, urinary tract infections (UTIs) caused by bacteria may result in green urine (pigments produced by Pseudomonas bacteria). This is a serious condition and medical intervention is usually recommended.
If there is no pain, it could be a sign of kidney or bladder cancer. It's very important to call your physician if you notice red/pink urine and you aren't experiencing any pain. A rare blood disease called polycythemia vera, can also cause red urine.
Blue or green: These hues are probably due to dyes in your food or meds you've taken, like the anesthetic propofol or the allergy/asthma medicine promethazine. A few rare medical conditions can also turn pee green or blue, so let your doctor know if the color doesn't go away after a short time.
If it's clear or straw-colored, then you're drinking sufficient fluid. If it becomes dark yellow or brown, then you are likely somewhat dehydrated,” says UCI Health urologist Dr.
Urine concentration: It's normal for urine to have a stronger odor first thing in the morning. After a night's sleep, urine is more concentrated and odorous as well as brighter yellow in color. Dehydration also increases urine concentration, causing stronger smelling urine.
