What causes high epithelial cells?

In general, elevated epithelial cells may be related to physiological cycle changes, intense physical activity, urinary tract infections, urinary stones, diabetes, and other factors. It is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Physiological Cycle Changes

During different phases of the menstrual cycle, women may experience increased estrogen levels, which can stimulate proliferation of epithelial cells in the urinary system, leading to a temporary rise in epithelial cell count. This typically does not require special treatment; maintaining good personal hygiene is usually sufficient.

2. Intense Physical Activity

After engaging in strenuous exercise such as running or playing sports, the body's metabolic rate significantly increases and blood flow accelerates, potentially causing enhanced microcirculation in the urinary system. This may lead to mild shedding or damage of urinary epithelial cells, resulting in a transient increase in epithelial cells detected in urinalysis. Adequate rest and sufficient fluid intake can help repair damaged urinary epithelial cells. Usually, epithelial cell counts return to normal after cessation of intense physical activity.

3. Urinary Tract Infection (UTI)

Urinary tract infections are primarily caused by bacterial infection-induced inflammatory responses. This inflammation can damage the mucous membranes of the urinary system, causing abnormal shedding of epithelial cells into the urine, thereby increasing epithelial cell counts in urine tests. Symptoms may also include frequent urination, urgency, and painful urination. Patients should follow medical advice and use medications such as norfloxacin capsules, amoxicillin capsules, or compound sulfamethoxazole tablets for treatment.

4. Urinary Stones

Urinary stones mainly cause irritation due to movement or impaction within the urinary tract. This process may irritate the urinary mucosa, causing local injury and inflammatory reactions, which promote epithelial cell shedding. This manifests as an increased number of epithelial cells in urine tests and may be accompanied by symptoms such as flank pain, abdominal pain, and hematuria. Treatment may include medications such as tamsulosin hydrochloride sustained-release capsules, terazosin hydrochloride tablets, or diclofenac sodium sustained-release capsules, used under a doctor’s supervision.

5. Diabetes

Diabetes is primarily triggered by a combination of genetic factors and unhealthy lifestyle habits such as long-term consumption of high-protein and high-calorie foods. It may damage epithelial cells of the urinary system, particularly those in the glomeruli and renal tubules, leading to abnormally elevated epithelial cell counts in urine. Other symptoms may include polyuria (excessive urination) and weight loss. Patients may follow medical instructions to use medications such as metformin hydrochloride tablets, glimepiride capsules, or liraglutide injection for treatment.

Maintaining healthy lifestyle habits—such as balanced nutrition, moderate physical exercise, and adequate rest—can help improve elevated epithelial cell levels and promote overall health.
