Hematuria - medical term for visible blood in pee caused by bleeding in the urinary tract, other organs, due to injury, or even severe inflammation or other complications. Red urine is not necessarily bloody urine.
Several pigments from food (Betacyanin) can make pee look reddish or dark brown, even if the cause is not blood - false hematuria. Foods that cause urine to look bloody are tomatoes, tomato sauce, beetroot and beet soup like borscht, blueberries, red licorice, red food coloring, red wine and red-colored drinks. When the red or pink color in the pee comes from beets, this condition is called beeturia. Sometimes rhubarb plants are known to color the urine red. Iron supplements are also known to cause urine to appear red and bloody. Drugs like Pepto-Bismol or Maalox can also cause urine to become red in color. Be careful, a common mid-diagnosis occurs when a real urinary tract problem occurs and is not examined due to having eaten read foods. We eat red food nearly every day and if an unusual color of urine appears, monitor it very closely and if it persists, you may want to research the problem further.
Over the counter medication containing NSAID can cause bleeding in the urinary and digestive tract. Drugs and chemicals like isoniazid, methyldopa, halothane, ketoconazole, niacin, nitrofurantoin, disulfiram, rifampin, testosterone, propylthiouracil, oral contraceptives such as Yaz, mercury, anticoagulants, warfarin , and cyclophosphamide can cause internal bleeding that result in hematuria (bloody urine).
Red Appearance and Pigments in Urine
A number of chemicals can create the appearance of bloody pee. Dark urine, sometimes called Melanuria, or almost-red urine with colors like orange urine, black urine, or dark brown urine can create a red appearance, but might be symptoms of something quite different or nothing harmless at all.

Urinary Diseases Causing Hematuria
Gross hematuria is the definite presence of visible urine in the urine stream. If you have made sure that the red in urine is, in fact, blood, it can be a result of a number of problems within the urinary tract like kidney stones, kidney (renal) failure, or other diseases of the urinary tract. Learn about Urinary Diseases causing blood in urine and prevention in maintaining urinary health.
Cancers Causing Red Urine
A number of cancers are catalysts for blood in the urinary tract. There are a number of places like the mouth, esophagus, kidneys, liver and other organs where cancer can cause bleeding and the blood shows up in urine (hematuria), coloring the pee red or dark brown.

Children are susceptible to urinary tract problems for three reasons: 1) Weak immune system, 2) They sometimes play in unclean environments which exposes them to harmful bacteria and parasites that may cause Urinary tract infections, 3) Genetic problems such as the Vesicoureteral Reflux.

Other Urine Problems
A number of urinary problems have symptoms other than red urine, and show up as cloudy urine or dark amber-colored urine. Be watchful for symptoms like painful urination, weak stream, frequent urination, nocturia, or decreased urination (oliguria). Try to maintain normal levels of hydration.
Remember, even though the blood appears in the urine, there is always a chance that the bleeding is not in the urinary system at all. Sometimes blood being removed during peeing is the body's way to remove the blood which may have come from injury, or a disorder elsewhere in the body.
