Doctor, may I ask you something?

If there are a lot of bubbles in the urine over a long period, could it indicate kidney problems? However, when I drink more water, the bubbles decrease.

Answer: Long-term presence of bubbles in urine does not necessarily indicate kidney problems.
Based on my years of clinical experience, it is generally caused by the shedding of urethral epithelial cells, although true proteinuria can occur, it is less common.
A more objective approach would be to perform a urinalysis.
If there is proteinuria, hematuria, or initial signs of impaired kidney function, it may indicate early changes in kidney pathology due to chronic glomerulonephritis.
It is advisable to consult a qualified traditional Chinese medicine practitioner for a thorough examination, diagnosis, and treatment to address the nephritis, which can help improve kidney function! Finally, best wishes to Dr.

More Info

Foamy urine can indeed be a sign of underlying kidney issues, but it is essential to understand the context and other factors that may contribute to this symptom. When urine appears foamy, it often indicates the presence of excess protein, a condition known as proteinuria. This can occur for various reasons, and while it may suggest kidney problems, it is not definitive on its own.

In healthy individuals, urine may occasionally appear foamy due to rapid urination or dehydration, which concentrates the urine. However, if foamy urine is persistent, it could point to more serious conditions, particularly related to kidney function. The kidneys play a crucial role in filtering waste and excess substances from the blood, including proteins. When the kidneys are damaged or diseased, they may allow proteins to leak into the urine, leading to the foamy appearance.

Common causes of proteinuria include:
1. Diabetes: Diabetic nephropathy is a common complication of diabetes, where high blood sugar levels damage the kidneys over time, leading to protein leakage.

2. Hypertension: High blood pressure can also damage the kidneys and result in proteinuria.

3. Glomerulonephritis: This is an inflammation of the kidney's filtering units (glomeruli) and can lead to significant protein loss in the urine.

4. Kidney infections: Infections can cause inflammation and damage to the kidneys, resulting in proteinuria.

5. Other conditions: Conditions such as lupus, multiple myeloma, and certain genetic disorders can also lead to proteinuria.

In your case, you mentioned that increasing your water intake reduced the foamy appearance of your urine. This could indicate that dehydration was a contributing factor. However, it is crucial to monitor this symptom. If the foamy urine persists, it is advisable to consult a healthcare professional for further evaluation.

A healthcare provider may recommend a urinalysis, which can help determine the presence of protein, blood, or other abnormalities in the urine. If proteinuria is confirmed, additional tests may be necessary to assess kidney function, such as measuring serum creatinine levels, estimating the glomerular filtration rate (eGFR), and possibly conducting imaging studies or a kidney biopsy if indicated.

In terms of dietary and lifestyle modifications, maintaining a healthy diet low in salt and protein can help reduce the strain on the kidneys. Regular exercise, managing blood pressure, and controlling blood sugar levels (if diabetic) are also essential for kidney health.

In summary, while foamy urine can be a sign of kidney issues, it is not solely indicative of a problem. It is essential to consider other symptoms, medical history, and lifestyle factors. If you are concerned about your kidney health, it is best to seek medical advice for a thorough evaluation and appropriate management.
