High epithelial cells are a very abnormal phenomenon, which is the result of urinary tract infections, increased urine and secretions, and the shedding of most of the epithelial cells of the urinary tract. 1. Infection of the urinary system. When the kidney has some small infections and problems, the epithelial cells will keep increasing, which is not a very good phenomenon. The problems of the kidneys are directly affecting the urinary system, these small problems drive the infection of the urinary system, the number of red blood cells and white blood cells will increase, it is still necessary to go to the hospital to check. 2. Increase in urine and secretions. If the body is not able to absorb and use the water drunk into the body well, then it will increase urine, and this time the increase in urine makes the bladder pressure increase, which will make the number of cells have changes. The body’s metabolism will increase secretions, which is also a small reason for the increase in epithelial cells. 3, the shedding of epithelial cells of the urinary tract. When the cells reach a certain time, they will keep shedding, making new cells start to appear to grow. High epithelial cells should be examined carefully to catch the cause before being able to treat it with confidence.
