Introduction

Elevated urinary microalbumin in pregnant women may be due to physiological causes, but pathological causes such as hypertension or diabetes cannot be ruled out. During pregnancy, the enlargement of the uterus may exert pressure on the heart, leading to the presence of microalbumin in the urine, which is considered a normal physiological phenomenon. Besides these reasons, it could also be caused by conditions such as renal failure.

Elevated microalbumin in pregnant women's urine may be caused by physiological reasons, but pathological causes such as hypertension or diabetes cannot be ruled out. Specific details are as follows:

1. Physiological Causes

During pregnancy, the enlargement of the uterus may exert pressure on the heart, potentially leading to the presence of trace amounts of albumin in the urine. This is considered a normal physiological phenomenon and generally does not require treatment.

2. Pathological Causes

1) Hypertension
Pregnant women are prone to elevated blood pressure, which can impair kidney filtration function. When kidney filtration capacity declines, small amounts of protein may be excreted in the urine. It is recommended to appropriately adjust lifestyle habits, and if necessary, take medications such as Nimodipine tablets, Nifedipine tablets, or Labetalol capsules under medical supervision to improve the condition.

2) Diabetes
Failure to control blood glucose levels during pregnancy may lead to gestational diabetes, which can result in microalbuminuria. It is recommended to manage diet carefully in daily life, and when necessary, use insulin injections to control blood sugar levels.

In addition to the above causes, renal failure could also be a possible factor. It is advisable to seek evaluation at a reputable hospital for proper diagnosis.

Is treatment needed for a high urine microalbumin level of 45?

A high level of microalbumin in urine, generally referring to 45 mg/L, usually does not require treatment if caused by physiological factors. However, if it results from pathological causes, targeted treatment should be carried out at a正规 hospital according to the doctor's recommendations. In addition, patients may undergo a kidney biopsy at the hospital to establish a definitive diagnosis.

Is high albumin a sign of poor liver function?

Albumin levels may be affected by liver dysfunction or other factors. Albumin is a protein synthesized by the liver and plays several important physiological roles in the body, such as maintaining blood volume, regulating plasma osmotic pressure, and transporting drugs and hormones. If blood albumin levels fall outside the normal range, it may indicate abnormal liver function. It is recommended to seek medical attention promptly.
