Urine odor refers to the scent of your urine as it flows out of your body. Your normal urine odor may be relatively mild and not too noticeable. Occasionally, your urine odor may be different in some way — ranging from sweet to foul — raising a concern about a problem or abnormality.
Many foods and medications, such as asparagus or certain vitamins, can affect the odor of urine. Sometimes, unusual urine odor may indicate a medical condition or disease, such as:
- Bladder infection
- Cystitis (bladder inflammation)
- Diabetic ketoacidosis (high levels of blood acids called ketones)
- Gastrointestinal-bladder fistula (abnormal connection between the intestines and bladder)
- Maple syrup urine disease (rare genetic disease that causes difficulty breaking down certain amino acids)
- Metabolic disorder (a problem with the way your body converts the foods you eat into energy)
- Type 2 diabetes (uncontrolled)
- Urinary tract infection
Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
