Fetal hypoxia refers to the inability of the fetus to obtain enough oxygen in the womb, resulting in abnormal placental function or other reasons. This situation has certain risks for both pregnant women and fetuses. Pregnant women will feel obvious discomfort and need to seek medical treatment in time. There are many symptoms of hypoxia experienced by pregnant women, such as dizziness, shortness of breath, fatigue, palpitation, numbness in hands and feet, etc. Since the mother\’s body will try to provide more oxygen to the fetus after the fetus is hypoxic, pregnant women may also experience symptoms of excess oxygen (oxygen poisoning), such as dizziness, nausea, vomiting, etc. The specific symptoms of hypoxia will vary according to the constitution and gestational age of the pregnant woman. Generally speaking, pregnant women are prone to feel dizziness, fatigue and other symptoms after physical activity or standing for a long time. If a pregnant woman\’s fetus is at risk of hypoxia, she may also experience other symptoms, such as reduced or changed fetal movement, vaginal bleeding, or abdominal pain. Hypoxia has a great impact on the fetus. If pregnant women are not treated in time, it is likely to lead to fetal dysplasia, mental retardation, congenital heart disease, etc., and even endanger the lives of the mother and baby. Therefore, pregnant women should pay attention to maintaining adequate sleep and diet during pregnancy, avoid standing for long periods of time, and maintain a happy mood. At the same time, they should also undergo regular prenatal check-ups to detect and treat hypoxia problems in a timely manner. In short, hypoxia is a serious problem faced by pregnant women and fetuses. If any symptoms of discomfort occur, pregnant women should seek medical treatment as soon as possible and follow the doctor\’s instructions for treatment to ensure the health of mother and baby. At the same time, pregnant women should also strengthen their awareness of self-protection, arrange their life and work reasonably, avoid overwork and inappropriate behavior, and ensure the healthy growth of the fetus.
