How long does it take for high uterine artery resistance in early pregnancy to improve with heparin treatment?
In general, during early pregnancy, it usually takes about 12 weeks of heparin treatment for high uterine artery resistance to return to normal. The detailed analysis is as follows:
During early pregnancy, high uterine artery resistance may lead to fetal growth restriction and other complications. To reduce uterine artery resistance, doctors may recommend heparin therapy for pregnant women. Heparin is an anticoagulant medication that helps improve blood circulation and reduce resistance in the uterine arteries. After starting heparin injections for high uterine artery resistance in early pregnancy, it generally takes around 12 weeks for resistance levels to normalize. However, if a pregnant woman is diagnosed with elevated uterine artery resistance, doctors may advise initiating heparin therapy early in pregnancy and continuing it for a period of time—typically until the uterine artery resistance decreases to within the normal range. During this period, the pregnant woman usually needs to administer a daily heparin injection and undergo regular prenatal check-ups to monitor improvements in uterine artery resistance and ensure normal fetal development.
It is recommended to maintain healthy lifestyle habits during pregnancy, attend regular prenatal examinations, and seek medical attention promptly if any discomfort or symptoms arise.
