Low blood creatinine in pregnant women usually does not have much effect. This situation usually occurs in the body type is relatively thin women, one of the reasons is first of all pregnant women glomerular filtration rate increases, accelerating the blood creatinine discharge, thus causing the blood creatinine value is relatively low. Secondly, pregnant women themselves have less exercise, muscle metabolism appears to be reduced, creatinine production itself is not much, so the test results show a low creatinine. Then there is the lack of nutritional intake, some pregnant women have a low appetite during pregnancy, unwilling to eat, not enough nutritional intake, this situation is recommended to consume more meat, such as beef, lamb, pork and so on. There is also the fact that due to the increase of fluid in the female body during pregnancy, which has a diluting effect on the blood creatinine, the test results will appear to be low creatinine. If the patient has no obvious discomfort, you can still observe the indicators dynamically.
