Can Blood in Urine Go Away on Its Own?

Short Answer:
Yes, blood in urine can fade on its own when the cause is mild.
But you still need a doctor to check it, even if it happens one time.

About 1 in 10 people see blood in their urine during life

Why Does Blood Show Up in Urine?

Many people come into Manhattan Medical Arts and say:

“Why am I peeing blood?”

It can feel scary. You may look at the toilet and worry right away.

Common reasons:

• UTI
  Burning, pressure, or a strong need to pee may show up.
  Changes in urine tests may also show Leukocytes in Urine or Leukocyte Esterase Urine.
• Kidney stones
  Sharp pain in the side or back is common.
  Stones often cause bleeding as they move through the urinary tract.
• Exercise
  Hard workouts can irritate the bladder.
  This may clear fast.
• Food
  Beets, berries, or food coloring can make pee look red.
  But this is not true bleeding.
• Infection or swelling inside the urinary tract
• Trauma
  A fall or blow to the back can cause bleeding.
• Prostate issues in men
• Kidney problems
  These include swelling of kidney filters.
• Cancer
  Less common, but must be checked.
  

Some people also have blood that they cannot see. This is called microscopic blood. A urine test can find it during a routine check.
When tests find Occult Blood in Urine or Urobilinogen In Urine, a doctor should review it.

Can It Go Away on Its Own?

Yes, sometimes. Blood may fade when caused by:

• Hard workouts
• Mild bladder irritation
• Light dehydration
• A small injury
• Food color changes
• A UTI once treatment starts

But fading does not mean the cause is gone. Some people tell me:

“It showed up once, then stopped.”

Even one time matters.
Some deeper issues may show blood only once.

This is why a doctor still needs to check it.

When It Will NOT Go Away on Its Own

You may need help if the blood stays or returns.

Ask yourself:

Do I have pain?
Do I see clots?
Does it hurt to pee?
Do I have fever?

These may show:

• Ongoing UTI
• Stone that has not passed
• Kidney swelling
• Prostate problems
• Infection
• Tumor
• Kidney disease
• Blood-thinner effects
• Ongoing bladder irritation

What Does Blood in Urine Look Like?

It may look:

• Pink
• Red
• Brown
• Tea-colored
• Rust-colored
• Like red streaks
• Like red dots
• Like small clots

Some people also notice mucus when a UTI or irritation is present. Learn more here: Mucus in Urine

If you are unsure, ask yourself: “Was my pee clear before? Is this new?”

Is It Serious?

Sometimes it is mild. Sometimes it is warning you about something deeper. Get help fast if you have:

• Trouble peeing
• Strong back or belly pain
• Strong fever
• Many clots
• Thick urine
• Bright red urine
• Feeling faint
  

These may need urgent care.
