What causes dizziness during pregnancy?

Many pregnant women experience dizziness during pregnancy. This situation must be taken seriously by pregnant women, because it will cause serious harm to their own bodies and will also endanger the health of the baby. The following content provides many pregnant women with a detailed introduction to the reasons for this situation so that you can have a comprehensive understanding.

1. In the early stages of pregnancy, due to the physiological changes that occur throughout the body of the pregnant woman to varying degrees, if the body cannot adapt, a variety of symptoms will appear, dizziness being one of them. If it occurs in early pregnancy, there are usually no adverse consequences.

(1) Pregnant women have autonomic nervous system disorders and the motor nerves that regulate blood vessels are unstable. When the body position changes suddenly, they may experience dizziness due to transient cerebral ischemia.

(2) Due to pregnancy reactions, the patient eats less, often accompanied by hypoglycemia, which can lead to dizziness and blurred vision. This is especially likely to occur when standing up suddenly, standing for a long time, taking a bath in a bathroom, or in a crowded crowd. If it happens, you should squat down immediately or lie down and rest for a while. If this phenomenon occurs frequently, you may suffer from anemia, low or high blood pressure, malnutrition or heart disease, and you should seek medical attention promptly.

2. In the middle and late stages of pregnancy, the main cause is anemia.

After pregnancy, in order to adapt to the growth needs of the fetus, the blood volume of the pregnant woman increases, and the blood is relatively diluted, forming physiological anemia. At this time, blood routine checks should be done regularly. If the anemia is severe, oral anti-anemia drugs are needed to correct it.

Dizziness and blurred vision that occur in mid-pregnancy are mostly due to a short circuit between the arteries and veins of the placenta, which reduces the resistance to dilation of peripheral blood vessels, causing the diastolic blood pressure of pregnant women to be lower than before pregnancy. In addition, the number of blood vessels in the entire pelvic area increases significantly during pregnancy and they dilate highly, causing more blood to be concentrated in the lower abdomen where the uterus is located. In addition, the enlarged uterus compresses the return of the inferior vena cava, reducing the amount of blood returning to the heart, resulting in a decrease in cardiac output, causing hypotension and transient cerebral ischemia.

Iron deficiency anemia is one of the most common blood diseases during pregnancy. In the early stages of pregnancy, the incidence is about 10%, while in the second trimester, the incidence can reach 38%.

If dizziness and blurred vision occur in the late pregnancy, especially when accompanied by edema, high blood pressure and other symptoms, it must not be taken lightly. It is often a precursor to certain serious complications such as eclampsia. You should seek medical attention as soon as possible, otherwise the consequences will be extremely serious. After excluding the above reasons, you need to go to the internal medicine department for a detailed physical examination to identify the specific cause so that active treatment can be carried out.

Dizziness during pregnancy is a disease that is relatively harmful to the body, and it also endangers the health of the fetus. Therefore, after this symptom occurs, many pregnant women must pay attention to it. After understanding the cause, they must go to the hospital for a comprehensive examination in time. After a comprehensive examination and finding out the cause, they should receive treatment as soon as possible to prevent dizziness during pregnancy.
