The enlargement of the uterus during pregnancy causes the diaphragm to lift up, which makes the lung function decrease and the cardiac blood displacement increase, and there is an increased load on the heart, resulting in chest tightness and shortness of breath.
If one is in good condition and has no respiratory or cardiovascular disease, it is generally a normal physiological phenomenon.
In case of chest tightness, keep your upper body straight, spread your shoulders backward, let your lungs expand as much as possible, and then take deep breaths to get enough oxygen.
In daily life, keep a happy mood, pay attention to rest, live regularly, don’t have too much exercise, keep enough sleep, don’t stay up late and strain.
In terms of diet, reduce the intake of high-fat, high-salt and high-sugar foods while ensuring nutrition to avoid excessive weight gain. Do regular pregnancy tests to ensure the health of the pregnant woman and her fetus.
