Cloudy urine


Hello, doctor.
Recently, I have noticed that my urine is sometimes cloudy, but there is no pain during urination.
Additionally, the cloudiness disappears when acetic acid is added.
However, when I drink more water, there is no cloudiness.
Could this be a sign of kidney stones, a urinary tract infection, or another issue?

Dr. Li Xinyi reply Urology


Changes in solvent, pH, or temperature can affect solubility.
Visual inspection may not reveal any issues.
It is still recommended to visit a hospital for a urine test.

More Info


Cloudy urine can be a concerning symptom, and understanding its potential causes is essential for determining the appropriate course of action. Based on your description, it seems that the cloudiness in your urine is intermittent and may be influenced by hydration levels. Here’s a detailed look into the possible causes and when you should seek medical attention.


Possible Causes of Cloudy Urine
1. Dehydration: When you are not drinking enough fluids, your urine can become concentrated, leading to cloudiness. This is often temporary and resolves with increased fluid intake, as you noted that drinking more water reduces the cloudiness.

2. Dietary Factors: Certain foods can affect the appearance of urine. For instance, consuming asparagus, beets, or foods high in protein can lead to changes in urine color and clarity.
3. Urinary Tract Infections (UTIs): UTIs are a common cause of cloudy urine, often accompanied by symptoms such as a strong urge to urinate, burning sensation during urination, or foul-smelling urine. However, you mentioned that you do not experience any pain during urination, which makes a UTI less likely.

4. Kidney Stones: While kidney stones can cause cloudy urine, they are usually associated with pain, especially if the stone is moving through the urinary tract. The absence of pain makes this less likely in your case.

5. Proteinuria: The presence of excess protein in the urine can lead to cloudiness. This condition can be a sign of kidney disease or other underlying health issues.

6. Acid-Base Imbalance: The fact that adding acetic acid (vinegar) clears the cloudiness suggests that the urine may have been alkaline. This can occur due to various metabolic conditions or dietary influences.


When to Seek Medical Help
While occasional cloudy urine, especially when associated with increased hydration, may not be a cause for concern, there are specific circumstances under which you should seek medical attention:
- Persistent Cloudiness: If the cloudiness persists despite adequate hydration, it is advisable to consult a healthcare provider.


- Accompanying Symptoms: If you begin to experience additional symptoms such as pain during urination, frequent urination, fever, chills, or back pain, these could indicate a more serious condition that requires medical evaluation.

- Changes in Urine Color or Odor: If you notice significant changes in the color or odor of your urine, particularly if it becomes foul-smelling, this warrants further investigation.

- History of Kidney Issues: If you have a history of kidney stones or other urinary tract issues, it is wise to discuss any changes in your urinary habits with a healthcare professional.


Conclusion
In summary, while occasional cloudy urine can be benign, especially if it resolves with increased hydration, it is essential to monitor for any additional symptoms or persistent changes. If you have concerns or if the cloudiness continues, it is best to consult a healthcare provider for a thorough evaluation. They may recommend a urinalysis or other tests to determine the underlying cause and provide appropriate treatment if necessary. Remember, your health is paramount, and seeking professional advice is always a prudent step when it comes to changes in your body.

Is that true? Could it be due to concentrated urine from not drinking water for too long? I suggest you go to the hospital immediately to see a nephrologist or urologist for an examination.

Hello: It is recommended to perform a urinalysis when there is turbidity, as it can provide better assessment. Generally, beverages in moderate amounts are unlikely to affect the appearance of urine; however, severe dehydration may have an impact. Wishing you good health.
