What You Need to Know About Blood Clots During Pregnancy
Published: Apr 27, 2024
Pregnancy increases the risk of blood clots, which can be dangerous for both mother and baby. Understanding how to prevent and treat blood clots is crucial for a healthy pregnancy.
Why Blood Clots Are a Concern in Pregnancy
During pregnancy, a woman's blood naturally becomes more likely to clot. This is the body's way of preparing to minimize blood loss during childbirth. However, this also means pregnant women are at higher risk for dangerous blood clots in the legs or lungs.
Who's at Risk?
Some women have a higher risk of blood clots during pregnancy. Risk factors include a history of blood clots, certain inherited conditions, being overweight, smoking, and prolonged bed rest. Women with mechanical heart valves are also at increased risk.
Prevention and Treatment Options
For high-risk women, doctors may recommend blood-thinning medications called anticoagulants. The most common types used in pregnancy are heparins, which don't cross the placenta. These are typically given as injections under the skin. The dose and frequency depend on individual risk factors.
Monitoring and Management
Women taking blood thinners during pregnancy need regular check-ups. Doctors will monitor blood counts and adjust medication doses as needed. It's important to follow the prescribed treatment plan closely and report any unusual symptoms promptly.
Frequently Asked Questions
