Hello, what are the reasons for oxygen deficiency in some pregnant women?

Patient's question:

No

Doctor's answer:

The child grows larger in the womb, and the burden on the heart increases. The heart needs to pump oxygen-rich blood for two people, which can lead to feelings of oxygen deprivation. It's okay, but if it's particularly severe, seek medical attention. Don't inhale oxygen randomly, as it's not good for the fetus. Maintain a balanced diet, eat a well-combined meal, get adequate rest, and stay warm.
