The presence of oil droplets in urine may be caused by factors such as indigestion, diet, and renal dysfunction. Here are the possible reasons:

1. Indigestion

Oil droplets in urine may be due to indigestion or kidney inflammation. Normal urine is light yellow and transparent. When excessive fats and proteins are consumed, the excess fats cannot be absorbed by the body and are excreted through urine, resulting in the presence of oil droplets in urine. Additionally, various types of kidney inflammation can lead to decreased filtration and reabsorption functions of the glomerulus and renal tubules, causing renal dysfunction. Large molecules of fats can then be excreted through urine. It is recommended to consult a doctor for urine routine tests and renal function assessments to help clarify the diagnosis.

2. Diet

The presence of oil droplets in urine may be related to dietary sources, including food and certain medications. Through metabolic processes, oily components may be filtered out by the renal tubules and glomerulus and excreted in urine, resulting in the appearance of oil-like substances. It is advisable to observe and consider whether there have been any special foods consumed recently, such as foods high in fats or plant-based fats, or other substances.

3. Renal Dysfunction

The presence of oil droplets in urine may indicate a problem with the kidney's filtration function for substances containing fatty components. There may be issues with the reabsorption function of certain substances. Another possible reason is chyluria, which occurs when small lymphatic vessels are connected to the collecting system of the renal pelvis. In this case, fatty components may enter the urine directly without being filtered by the kidneys.
