Why Is My Urine Smelly?
Your urine's smell can change due to several factors. Often, a strong odor simply indicates dehydration. When urine is highly concentrated (meaning it contains more ammonia and less water), it smells stronger. This is common first thing in the morning or if you haven't drunk enough fluids throughout the day.
Several factors contribute to smelly urine, ranging from harmless dietary choices to underlying medical conditions.
-
Dehydration: Not drinking enough water leads to concentrated urine with a more pungent ammonia smell. [Reference: When urine is highly concentrated, it contains more ammonia and less water. This can cause it to have a strong smell. Urine tends to be more concentrated when a person is dehydrated. This is often the case first thing in the morning or when someone does not drink enough water throughout the day.]

Medications: Some medications can affect urine odor. [Reference: NHS, WebMD]
-
Urinary Tract Infections (UTIs): Bacteria in the urinary tract can produce a foul smell. [Reference: Healthline, MedlinePlus] This often comes with other symptoms like pain or burning during urination.

Kidney Stones: These can cause an ammonia-like odor. [Reference: nidirect]
-
Diabetes: Uncontrolled diabetes can cause a sweet smell in urine. [Reference: MedlinePlus]
-
Other Medical Conditions: Rare metabolic disorders can also affect urine odor. [Reference: MedlinePlus]
Less Common Causes
While less frequent, these conditions can also cause unusually smelly urine:
-
Bladder fistula: An abnormal connection between the bladder and another organ. [Reference: nidirect]
-
Certain Vitamins: High doses of certain vitamins, particularly vitamin B6, can also affect the smell of your urine. [Reference: NHS]
When to See a Doctor
While a change in urine smell is often harmless, it's important to consult a doctor if the smell is:
- Persistently strong or unpleasant
- Accompanied by other symptoms, such as pain, burning during urination, frequent urination, or changes in urine color.
Consulting a healthcare professional is crucial for proper diagnosis and treatment of any underlying medical condition.
