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. Colorless urine may indicate over-hydration. While not as dangerous as dehydration, over-hydration can dilute essential salts, such as electrolytes, creating a problematic chemical imbalance in the blood.
Amber or honey. Possibly dehydrated. Note: A lot of popular sites recommend drinking water to address some of the colors above, but Dena Rifkin MD, a staff nephrologist at UC San Diego Health and assistant professor of medicine, suggests prudence.
Light orange. Possibly dehydrated, but may also be caused by liver or bile duct problems, consumed food dyes or the excretion of excess B vitamins from bloodstream. Talk to your doctor. Some medications, such as rifampin or phenazopyridine, can cause this coloration. But if red pee lingers, Dr. Shaw says, it could be a sign of a bladder or kidney tumor. Both tumors are extremely rare, but underdiagnosed in women, who are more likely to shrug off the incident as a weird period fluke , Dr.
Shaw adds. Blood in the urine can also be caused by other conditions, such as urinary tract infections , an enlarged prostate, or kidney cysts or stones. If you notice any other unusual symptoms alongside the red or pink color of your urine, such as burning, pain , or an odd smell , that also warrants a visit to the doc.
Just like your skin can skew orange when you eat too many carrots, so can your pee. Certain meds, like the over-the-counter UTI treatment phenazopyridine Pyridium , the blood thinner warfarin, and some laxatives can also result in orange pee. The good news, Dr. If you see more of a neon or fluorescent orange, though, something could be up with your liver, especially if you notice a yellowish tint to the whites of your eyes, Dr.
Orange pee that skews slightly more brown could also just be a sign of dehydration. A vibrant, fluorescent yellow in your bowl is probably linked to your vitamin stash. B vitamins, especially B12, result in this dramatic hue change. The medications most known to turn your liquid discharge blue are the pain reliever indomethacin, the antidepressant amitriptyline, the stomach acid drug cimetidine, and the anesthetic propofol.
Asparagus could also add a greenish tinge but it is more known for adding an odor. Purple is the only color that has a syndrome named after it, purple urine bag syndrome.
This occurs in rare cases when using a urinary catheter where the patient also has a co-existing urinary tract infection. But changes can also be a sign of a more serious underlying medical condition. Anytime you see blood in your urine or notice it is brown or orange, it is time to seek medical attention and make an appointment with your primary care provider. This is especially true if the change lasts more than a day, or if it comes with back or side pain, fever, burning with urinating, vomiting, discharge or thirst.
Blood in the urine is a common sign of a urinary tract infection, kidney stones or urinary tract cancer. Brown or orange urine may be caused by a malfunctioning liver especially if it is partnered with pale stools and yellow eyes and skin. On top of your urine color, I also recommend paying attention to the smell while going to the bathroom. Changes in smell could be caused by a range of underlying conditions but also could be because of your latest meal.
If diet is suspected as is common with asparagus , try eliminating the culprit. Contact your primary care physician if the odor persists.
A urologist does not need to be the first line of care for most urinary color problems. Make an appointment with your primary care provider, who will refer you to a specialist like the providers at Urology Associates if it is needed. Anesthesia was induced with morphine 6 mg and propofol mg, and tracheal intubation was facilitated by vecuronium 6 mg.
Anesthesia was maintained with isoflurane 0. Two hours after methylene blue use, a change in urine color was observed from normal yellow to green [ Figure 1 ]. The intraoperative period was uneventful. Surgery lasted for 5 h. At the end of surgery, residual neuromuscular block was reversed neostigmine, glycopyrrolate. The postoperative period was unremarkable. Patient's urine color became normal 8 h postoperatively. Methylene blue, a nonpathogenic water-soluble dye, is used intraoperatively for diagnostic tests fistula detection, patency of fallopian tubes, and identification of parathyroid glands.
Methylene blue-induced green urine has been reported previously. Some are excreted unchanged in the urine. Blue urine is rare because the blue pigments combine with urochrome yellow pigment in urine resulting in green urine. The presence of these two peaks in a green urine sample confirms the presence of methylene blue.
