What causes dizziness in late pregnancy?

We all know that a woman's body will undergo some changes after she becomes pregnant, especially in the late pregnancy. As the fetus gradually grows and develops, the demand for nutrition will be particularly high, which can easily lead to some symptoms in pregnant women. Among them, dizziness in the late pregnancy is a phenomenon that many women have experienced. If it is not relieved in time, there will be certain dangers. At the same time, it will have a great impact on normal life. Let's understand what causes dizziness in the late pregnancy.

What causes dizziness in late pregnancy?

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

1. Pregnant women with low blood pressure and cerebral ischemia usually faint when they stand up suddenly or take the elevator. In the early and middle stages of pregnancy, due to the formation of the placenta, blood pressure drops to a certain extent, generally 1.33-2.67 kPa lower than usual, which is physiological. For pregnant women with pre-existing hypertension, the drop in blood pressure will be even greater. When blood pressure drops, blood flow to the brain will decrease, resulting in insufficient blood supply to the brain, causing cerebral ischemia and hypoxia, which in turn causes dizziness.

2. Eating too little and having low blood sugar. Pregnant women of this type sometimes experience dizziness, accompanied by palpitations, fatigue, and cold sweats, which usually occur when they eat less. During pregnancy, I ate less because of the pregnancy reaction - vomiting. Eating less will cause low blood sugar. Blood sugar is the raw material for muscle cells and brain cells to produce energy. When blood sugar is low, cell energy is reduced, leading to fatigue, dizziness, cold sweats, palpitations and other discomforts.

3. Improper posture compresses blood vessels. This type of pregnant woman usually has an attack when she is lying on her back or sitting on the sofa watching TV, but not when she is lying on her side or standing. This type of dizziness in pregnant women is a condition called supine syndrome. In the late stages of pregnancy, due to the enlarged uterus, when the woman lies on her back or sits lying down, the heavy uterus presses on the inferior vena cava behind it, preventing blood from returning to the heart from the lower body. The amount of blood returning to the heart is sharply reduced, and the cardiac output is reduced, resulting in reduced blood supply to the heart and brain, causing dizziness, chest tightness and other discomforts.

4. Anemia in pregnant women is also a common cause of dizziness in pregnant women. Pregnant women should usually consume iron-rich foods, such as animal blood, pork liver, lean meat, etc. Once anemia occurs, iron supplementation should be done urgently. Pregnant women may also experience symptoms such as dizziness and headaches. If the disease further develops into preeclampsia, it can cause convulsions and coma, endangering the lives of pregnant women and fetuses. This is the most serious complication during pregnancy and should be diagnosed and treated early.

The above is an introduction to what causes dizziness in the late pregnancy. If such symptoms occur, we must make timely adjustments. If we cannot grasp the cause, we must go to the hospital for examination. In addition, we must pay attention to the quality of diet in the late pregnancy, eat more nutritious and light foods, and also go to the hospital regularly for prenatal check-ups and maintain a happy mood.
