Why is my urine foamy even when I drink plenty of water at 24?

Question

Hello doctor,

I am 24 years old and have lupus. Lately, I have noticed that my urine has been looking very foamy, even though I drink a lot of water.

At first, I thought I might be dehydrated, but it has not gone away. Then I made the mistake of searching online, and now I am starting to worry. I read about lupus nephritis, and now that is all I can think about.

Should I get this checked as soon as possible, or am I worrying for nothing?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

Hello, and I hope you are doing well.

Please do not feel worried. Like any lupus flare, lupus nephritis can often be managed successfully with appropriate treatment, and many patients recover well. At this point, we are not even sure that you have lupus nephritis. Not all foamy urine is caused by proteinuria. The first step is to confirm or exclude this possibility.

I recommend the following investigations:

Urine routine analysis.
Twenty-four-hour urinary protein estimation.

The findings are more concerning if:

Urinary protein exceeds 500 mg in 24 hours.
There is blood in the urine (hematuria).
Urinary casts are present.

If these abnormalities are found, a kidney biopsy may be required to determine the degree of kidney involvement and classify lupus nephritis.

I also recommend the following blood tests:

Complete blood count (CBC).
Erythrocyte sedimentation rate (ESR).
C reactive protein (CRP).
Alanine aminotransferase (ALT).
Aspartate aminotransferase (AST).
Serum creatinine.
Anti-double-stranded DNA (deoxyribulose nucleic acid) antibody (anti-dsDNA).
Complement C3.
Complement C4.

Based on the results and, if required, the biopsy findings, the treatment plan can be determined.

Therefore, there is no need to frighten yourself, but it is equally important not to ignore these symptoms. Please complete the recommended investigations promptly and continue regular follow-up with your rheumatologist or nephrologist.

If lupus nephritis is confirmed, treatment commonly includes:

Prednisolone 1 mg per kg per day.
Mycophenolate mofetil 2 g per day.
Hydroxychloroquine 5 mg per kg per day.
Calcium and vitamin D supplementation.

These medications should only be started under the guidance of your treating physician after the laboratory results and overall clinical assessment.

I suggest some preventive measures; please follow them.

Avoid nephrotoxic medications whenever possible.
Avoid unnecessary analgesics, especially nonsteroidal anti-inflammatory drugs.
Maintain adequate hydration.

Please follow up after your laboratory results are available so that further management can be planned accordingly.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
