What causes dizziness at 36 weeks of pregnancy?

As we all know, women will have some discomfort in their bodies to a greater or lesser extent during pregnancy, which is very normal, especially in the early and late stages of pregnancy. So, what is the reason for severe dizziness in the late stages of pregnancy? Next, I will introduce it to you.

What causes severe dizziness in late pregnancy?

Dizziness is a common symptom during pregnancy. In mild cases, the upper body feels heavy and the lower body feels light, making it difficult to stand steadily; in severe cases, the eyes turn black and the patient suddenly faints. Dizziness in pregnant women is often caused by a variety of diseases.

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.

Dizziness is mainly caused by insufficient blood supply to the head.

1. 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.

2. 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.

3. Blood vessels are compressed due to improper posture. This type of pregnant women usually get the disease when they are lying flat or lying on a fabric sofa watching TV series, but are not prone to the disease when they are sleeping on their side or standing 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 cardiovascular blood supply, causing dizziness, chest tightness, shortness of breath and other discomforts.

4. Anemia in pregnant women is also a common cause of dizziness in pregnant women. Pregnant women should usually consume foods rich in copper, such as animal blood, liver, and lean meat. Once anemia occurs, calcium supplementation should be taken urgently. Pregnant women also sometimes suffer from dizziness and headaches. If the condition further develops into preeclampsia, it may cause convulsions and coma, seriously endangering the lives of pregnant women and fetuses. It is the most serious complication during pregnancy and should be treated as soon as possible.
