Does pregnant woman chest tightness fetal meeting anoxia?

During pregnancy, most pregnant women will have dyspnea, faster respiratory rate, faster heartbeat, chest tightness and other phenomena, which are related to the rapid growth of the fetus in the body, the increase of oxygen demand, the decrease of pregnant mother's chest and other factors. If it is not caused by high-risk pregnancy diseases, the fetus does not appear to increase fetal movement, or the pregnant woman is seriously weak and other phenomena, there is no need to worry too much. However, if pregnant women have severe dyspnea, they must seek medical treatment in time.

Pregnant women provide a variety of nutrients and the most important oxygen for the fetus. If the pregnant woman has shortness of breath and severe hypoxia, it may cause the decrease of blood oxygen saturation and affect the blood and oxygen supply to the placenta, then the fetus may also suffer from hypoxia. In the last few weeks of pregnancy, after the fetus drops to the pelvic cavity, the pregnant mother's breathing will become smooth. This wonderful change will enable the expectant mother to cultivate her physical strength again and prepare for childbirth.

During pregnancy, you need to breathe more oxygen, and your body will adjust accordingly to meet your oxygen needs. The increase of hormones during pregnancy, especially progesterone (also known as progesterone), can directly affect your lungs and stimulate the respiratory center of your brain. During pregnancy, the number of times you breathe per minute doesn't change much, but the amount of air you inhale each time increases significantly, resulting in shortness of breath.
