Cause 1: postural hypotension: the most common cause of syncope during pregnancy is postural hypotension, which occurs when the pregnant mother suddenly stands upright or supine for a long time from lying or sitting position. After pregnancy, the blood volume of pregnant mother increased significantly, the heart rate increased, the blood pressure decreased in the first three months of pregnancy, and the lowest in the second trimester of pregnancy. The original hypertensive pregnant mother, blood pressure drop will be greater, easy to cause insufficient blood supply of brain tissue, cause dizziness. This situation will gradually improve with the increase of heart rate and stroke volume. In addition, in the second and third trimester of pregnancy, when the pregnant mother is lying on her back for a long time, the enlarged uterus compresses the inferior vena cava, which reduces the amount of blood flow back to the heart, reduces the cardiac output, and causes the decrease of blood pressure, which is called supine hypotension.
Reason 2: hypoglycemia: the demand for various nutrients during pregnancy increases significantly. Insufficient intake can easily lead to hypoglycemia and syncope. The manifestations of hypoglycemic syncope are cold sweat, palpitation, weakness or fainting.
Reason 3: anemia: the increase of blood volume during pregnancy, the increase of plasma volume is higher than the increase of blood cell number, the blood is diluted, and the fetus will give priority to the intake of iron in maternal blood to meet their own needs, so pregnant mothers are prone to anemia. Anemia, the body will deliver oxygen to the brain and other organs of the red blood cell number will be less than normal, so pregnant mothers will feel dizzy, posture change or emotional excitement is very prone to syncope.
