Urine that is red or reddish brown may contain blood. The urine can also be red colored by things that the child has eaten, such as beets or some medicines. The most common cause of blood in the urine of children is urinary tract infection. If the child has a urinary tract infection, they are treated with antibiotics.
There are several reasons why the urine may look red or reddish brown, for example that you have eaten beets or that menstrual blood has come. But it may also be because the urine itself contains blood. Sometimes you may need treatment.
