Introduction
In general, it is not recommended to fly during the first trimester of pregnancy (less than 12 weeks), as it may adversely affect embryonic development. During early pregnancy, before 12 weeks, the placenta has not fully formed and the embryo's implantation in the uterine wall is still unstable. Due to adverse factors such as changes in air pressure at high altitudes or cosmic radiation exposure during flight, flying during early pregnancy may negatively impact embryonic growth and development, cause physical discomfort, and increase the risk of threatened miscarriage.
In general, pregnant women who are less than three months into their pregnancy should not fly, as it may adversely affect embryonic development. If any discomfort occurs, prompt medical attention is recommended. Detailed analysis is as follows:
Pregnancy of less than three months falls within the first trimester. During this period, the placenta has not fully developed and the embryo's implantation in the uterine lining is unstable; the connection between the embryo and the mother is not yet strong. Therefore, excessive physical activity and heavy labor are generally not recommended. Due to adverse factors such as changes in air pressure at high altitudes and cosmic radiation during flight, flying during early pregnancy may negatively impact embryonic growth and development, cause physical discomfort, and increase the risk of threatened miscarriage.
If symptoms such as abdominal pain or vaginal bleeding occur during a flight, timely treatment to preserve the pregnancy is advised. Medications such as dydrogesterone tablets, progesterone capsules, or Baotailing capsules may be taken under medical supervision.
Pregnant women are advised to consult both airline customer service and their healthcare provider before flying and to follow medical advice accordingly.
