What causes dizziness during pregnancy?

Dizziness is a common symptom during pregnancy. You can eat more light-tasting foods. In mild cases, you may feel upper-heavy and unable to stand steadily; in severe cases, your eyes may turn black and you may suddenly faint. Dizziness in pregnant women is a normal reaction during pregnancy, but if the dizziness occurs frequently and becomes more severe, you should go to the hospital for examination to avoid adverse effects. So below I will give a detailed introduction to the question of what causes dizziness during pregnancy. I hope it will be helpful to some people.

What causes dizziness during pregnancy?

First: Pregnant women with slightly low blood pressure and cerebral ischemia usually faint when they stand up suddenly or take the elevator. In the early, middle and late stages of pregnancy, due to the formation of the embryo, blood pressure will drop to a certain extent, generally 1.33-2.67 kPa lower than usual, which is physiological. It turns out that for pregnant women with hypertension, the blood pressure can be lowered more significantly. When blood pressure drops, the volume of blood flowing to the brain will decrease, resulting in insufficient blood supply to the brain, insufficient oxygen to the ischemic areas of the brain, and thus causing dizziness.

Second: Eating too little and having low blood sugar levels sometimes cause dizziness in pregnant women, accompanied by palpitations, fatigue, and sweating, which usually occurs when they eat too little. During pregnancy, I eat less because of the pregnancy reaction - vomiting. Eating less will cause low blood sugar. Blood sugar is the raw material for muscle cells and nerves to generate energy. When blood sugar is low, body cell energy is reduced, which can cause discomfort such as drowsiness, dizziness, sweating, and palpitations.

Third: Improper posture compresses blood vessels. This type of pregnant women usually get the disease when they lie flat or lie on a fabric sofa watching TV series, but are not prone to the disease when they sleep on their side or stand up. This type of dizziness in pregnant women is attributed to supine syndrome. In the late stages of pregnancy, due to the enlargement of the uterus, when lying flat or sitting still, the heavy uterus presses on the inferior vena cava behind it, making it impossible for blood from the lower body to return to the heart; the force of returning to the heart is suddenly reduced, and the cardiac output is small, resulting in reduced blood supply to the heart and brain, causing dizziness, chest tightness, shortness of breath and other discomforts.
