I’ve been noticing foam in my urine more frequently—what could be the reason?
It didn’t used to happen when I woke up, but these days I see a small amount in the morning, and more foam during the daytime.
I heard it could be related to diabetes, so I’ve reduced snacks and have been exercising consistently for the past few months, but I’m still not sure why this is happening.
Also, I used to be overweight, but I’ve lost weight and now maintain a normal to slightly overweight range. I do have a habit of eating snacks—could this be related to diabetes?

Hello, this is Dr. Changki Lee from Goldman Urology Clinic, Incheon.
Foamy urine can be associated not only with systemic conditions such as proteinuria or diabetes, but also may reflect the condition of the kidneys or urinary tract.
It is positive that you are exercising regularly and have lost weight. However, if your symptoms are more noticeable during the daytime, it is important to evaluate the possibility of orthostatic proteinuria (which occurs during activity) or changes in urine concentration.
Proteinuria may be a sign of reduced kidney function, and similar findings can also appear in inflammatory conditions such as cystitis or urinary tract infections.
Rather than worrying on your own, it would be advisable to visit a urology clinic for proper evaluation, as early testing can help prevent potential health issues.
At our clinic, we carefully assess each patient’s symptoms and overall health condition based on extensive clinical experience, providing accurate diagnosis and personalized treatment plans.
Identifying the exact cause is the first step toward effective treatment.
If your symptoms persist, we recommend visiting a urology clinic for further evaluation.
Thank you, and we hope this information was helpful.
