Oil flower in urine may be related to physiological factors such as high-fat diet, or it may be caused by pathological factors such as renal lesions, steatorrhea, urinary tumors and tuberculosis, filariasis and so on. 1. Physiological factors: frequent eating some high-fat food, the body produces too much fat, the renal tubules can not be completely reabsorbed, in the urine will appear in the oil, through a low-fat diet, drink more water and other lifestyle modification can be improved. 2. Fatty urine: often caused by fat extrusion, injury, bone fracture and bone disease syndrome, due to excessive fat into the urine, resulting in urine oil flowers. 3. Kidney disease: when there is nephrotic syndrome, glomerulonephritis and other kidney diseases, the filtration function of the kidneys decreases, and some large molecules of protein or lipids will enter into the urine, which may also appear in the urine oil flowers. 4. Tumor or tuberculosis: when a malignant tumor may compress the abdominal lymphatic vessels or thoracic ducts, which may lead to lymphatic obstruction, and urinary tract tuberculosis may invade the lymphatic vessels, resulting in celiac disease, and the urine may appear oily. 5. Filariasis: Filariasis may also lead to inflammatory reactions in the lymphatic vessels, resulting in lymphatic vessel blockage and hyperplasia, and the occurrence of celiac disease, which is also a factor in the appearance of oil in the urine. The presence of oil flowers in the urine, it is recommended to consult a doctor in a timely manner, and follow the doctor’s instructions for standardized treatment.
