What causes high white blood cells in urine during prenatal checkups?

Generally, elevated white blood cells in urine during pregnancy checkups may be related to specimen contamination, special physiological conditions, immune system abnormalities, gestational diabetes, or pyelonephritis. It is recommended to consult a professional physician for further evaluation. Detailed explanations are as follows:

1. Specimen Contamination

During the collection, transportation, or testing of the urine sample, contamination by external bacteria may also lead to an increased white blood cell count. The urine should be collected using a clean, dry container and sent for testing as soon as possible.

2. Special Physiological Condition

Pregnancy itself is a special physiological state. Hormonal levels and metabolism in the pregnant woman's body undergo significant changes, and the body may exhibit some adaptive alterations. Occasionally, this may also result in a small number of white blood cells appearing in the urine.

3. Immune System Abnormalities

Changes in immune system regulation during pregnancy may lead to elevated white blood cells in the urine. The urinary tract becomes more susceptible to bacterial invasion, allowing bacteria to multiply within the urinary system, triggering an inflammatory response. This causes white blood cells to accumulate to fight the infection, thereby increasing the white blood cell count in the urine. Symptoms such as frequent urination, urgency, and painful urination may also be present.

4. Gestational Diabetes

Elevated blood glucose levels during pregnancy increase sugar content in the urine, making it easier for bacterial growth and subsequent infection, which can lead to elevated white blood cells in the urine. It is important to monitor blood glucose levels, adjust dietary patterns, and avoid high-sugar and high-fat foods such as cakes, fried chicken, and hamburgers. Medications such as insulin glargine injection or insulin aspart injection may be used after consulting with a physician to help manage the condition.

5. Pyelonephritis

When a urinary tract infection worsens and bacteria ascend to the renal pelvis, kidney inflammation may occur, potentially causing elevated white blood cells in the urine. It is recommended to follow medical advice and use medications such as cefixime capsules, minocycline hydrochloride capsules, or cefixime granules to alleviate symptoms. Additionally, adequate rest and appropriate electrolyte balance maintenance are important.

If a pregnant woman experiences elevated white blood cells in the urine, she should seek medical attention promptly and inform the physician of relevant symptoms and lifestyle habits to assist in accurate diagnosis and formulation of a treatment plan. Pregnant women should maintain a light diet during pregnancy and increase intake of vitamin-rich vegetables and fruits such as tomatoes, carrots, and grapefruits to enhance immunity and promote overall health.
