Urine with Strong Odor

DESCRIPTION

The urine has a pungent, often unpleasant odor of recent onset. The color of the urine is usually darker than normal at these times.

CAUSES

Most strong-smelling urine is produced when your child is mildly dehydrated. Exercise, a fever, hot weather, or a hot room can lead to slight dehydration. Children in cloth diapers can acquire a strong odor of ammonia if the bacteria in the stool have time to break down the urine. Certain drugs (e.g., penicillin and ampicillin) are excreted in the urine and cause an unusual odor. Certain foods (e.g., asparagus) or a high-protein diet lead to strong-smelling urine.

SIMILAR CONDITIONS

A dark-yellow urine may contain bilirubin; check the whites of the eyes for a yellow color change (i.e., jaundice). Urinary tract infections cause foul-smelling urine. Blood in the urine can cause pink, red, or cola-colored urine.

If one of the following is suspected, save time by selecting that guideline:

Jaundice

Pain with Urination

HOME CARE

Increase your child's water intake during warm weather and fevers. Reduce your youngster's protein intake (remember that milk is largely a protein). Most of these odors are not caused by anything harmful.

CALL YOUR CHILD'S PHYSICIAN DURING OFFICE HOURS IF:

  • The unusual odor lasts more than 24 hours without explanation.
  • You have other questions or concerns.
