Why urine have blood?

Blood in the Urine (Hematuria)

When blood gets into a person's urine, doctors call it hematuria (hee-ma-TUR-ee-uh). Hematuria is pretty common, and most of the time it's not serious.

Urine is one way our bodies get rid of waste products. The process starts in the kidneys, which remove excess fluids and waste from the blood and turn them into urine. The urine then flows through tubes called ureters into the bladder, where it's stored until we pee it out. If blood cells leak into the urine at any part of the process, it causes hematuria.

There are two kinds of hematuria:

  1. Microscopic hematuria is when blood in the urine is invisible to the naked eye; it only shows up under a microscope. Most of the time, microscopic hematuria goes away without causing any problems. In fact, people might never know they have it unless they get a urine test.
  2. Gross hematuria may sound nasty, but it's usually not — in medicine, "gross" is just a word that describes when something is large or happens in bigger amounts. Gross hematuria just means that enough red blood cells are in a person's urine to turn it red or tea colored. Like microscopic hematuria, gross hematuria often clears up on its own with no problems. Sometimes, though, it can be a sign of a more serious condition.

Causes

Teens can get hematuria for many reasons. The more common causes are:

  • bladder or kidney infections
  • defects in the structure of the urinary tract
  • inherited diseases
  • mineral imbalances in the urine, like too much calcium

Other reasons why teens get hematuria are menstruation, vigorous exercise, injuries to the kidneys or urinary tract, and the use of certain medicines — like some over-the-counter pain relievers. Many athletes, especially distance runners, get hematuria from time to time.

In rare cases, hematuria can be a sign of something more serious, like a blood disease or a blood clot. If something like that is going on, hematuria will usually be one of many other symptoms.

Very occasionally, what looks like hematuria might be something else. It's possible (though unlikely) that things like food dye, beets, or certain medications can make a person's urine look red.

What Doctors Do

If you ever see blood in your urine, don't panic. Chances are, it's no big deal, but you'll want to be sure. So tell your mom or dad and see a doctor. If you need treatment, it's good to get started right away.

If you see a doctor about blood in your urine or if microscopic hematuria shows up on a urine test, the doctor will give you a physical examination. He or she will ask you and your parent questions about recent activities and family medical history. You'll probably need to provide a urine sample, which means peeing in a cup.

If the urine test comes back negative, the doctor will probably want another urine sample 1-2 weeks later to make sure the urine is free of red blood cells. If hematuria only happens once, there's usually no need for any treatment.

What if tests show you have microscopic hematuria? If you don't have any symptoms like pain or fever, you haven't had a recent injury, and there's no protein in your urine, your doctor will repeat a urine test several times over a few months to see if you still have blood in your urine.

Imbalance in my brain. I have a b6 dependency and this nutrient is needed for both tyrptophan (serotonin) and dopamine levels. So, to say that this is not the case, sorry, but you can not ever prove a negative. And that is what you are tyring to prove here.
And yes there are tests, urine and blood tests, that will show what neurotransmitters are low. This is not something most shrinks know about or seem to care about, but these tests are available.
