Eight months pregnant dizziness and shortness of breath

For pregnant women, it is very common for the body to experience discomfort, so many pregnant women are not surprised when dealing with new symptoms. However, if a woman experiences palpitations and chest tightness during the eighth month of pregnancy, she will inevitably feel anxious and worried, especially for women who are pregnant for the first time. So, what is the reason for dizziness, palpitations and chest tightness in the eighth month of pregnancy?

1. The lungs have less and less space to move. As the fetus grows, it will gradually occupy most of the space in the abdomen, so the activity space of some internal organs will be reduced. When the lung activity space becomes smaller, lung function will also shrink, which will cause pregnant women to feel anxious frequently, which is also a normal reaction in late pregnancy.

2. Changes in blood volume. As the pregnancy progresses, the blood volume of pregnant women will gradually increase, because this can ensure that there are enough nutrients to provide for the fetus. When a pregnant woman reaches eight months of pregnancy, her blood volume reaches its highest point, and can even be 45% higher than in the early stages of pregnancy. Under such circumstances, the pregnant woman's heart rate will also increase, causing her to feel anxious and chest tightness.

3. Autonomic nervous system disorder. The body's autonomic nerves themselves have a certain buffering effect on some uncomfortable reactions of pregnant women. When pregnant women experience palpitations and chest tightness, if the autonomic nerves can play a good buffering role, they can effectively alleviate this discomfort. When the autonomic nervous system is disordered, this discomfort will be reflected, causing pregnant women to experience symptoms such as palpitations, chest tightness, etc.

After mastering the above content, pregnant women can learn to let go of their worries and wait for delivery comfortably, and the symptoms of panic and shortness of breath will gradually weaken and subside. It should be noted that if the pregnant woman has other discomforts in addition to symptoms of panic and shortness of breath, and the fetus also has obvious abnormalities, then the panic and chest tightness may be caused by pathological reasons, and the pregnant woman needs to go to the hospital for a physical examination immediately to avoid problems with the fetus.
