Started experiencing leg swelling, lower back pain, and excessive thirst from the third month of pregnancy.

Patient's question:

Pregnancy-related leg edema starting from the 3rd month and lasting until 4 months postpartum, lower back pain, and excessive thirst

Doctor's answer:

NAG is one of the indicators reflecting proximal tubular injury, but it is influenced by many factors, with significant fluctuations in values. A single elevated reading generally lacks clinical significance and requires multiple follow-up tests along with comprehensive analysis that includes blood urea nitrogen, creatinine levels, and 24-hour urine protein measurements. Therefore, it is currently not possible to confirm that you have kidney disease combined with pregnancy. Additionally, your microalbumin level is normal.
You currently have lower back pain, edema, and thirst. It is recommended to monitor your blood pressure, undergo an abdominal ultrasound, check your blood sugar, and assess your renal function. If no abnormalities are found, you can safely wait for a period of observation.
