It is normal to experience this phenomenon when the relevant systemic disease is ruled out. After 28 weeks of pregnancy, as the pregnant woman continues to gain weight, her mobility becomes less and less convenient. At the same time, the heart and lung systems of pregnant women are under a double burden.
The reason for the difficulty in breathing is often due to the increased size of the uterus, which presses upwards on the abdominal diaphragm, thus reducing the volume of the thorax and affecting the breathing capacity, causing shortness of breath and a feeling of suffocation. Therefore, it is absolutely necessary to avoid excessive fatigue and strenuous exercise. It is also important to take rest, to talk about a balanced diet, to reduce the intake of foods high in fat, salt and sugar and to have regular pregnancy tests.
