What causes dizziness and blurred vision during the second trimester of pregnancy?
I've been pregnant for more than 4 months, and recently I've been experiencing frequent dizziness and vertigo, feeling as if everything is spinning around me. I also feel a bit unsteady on my feet. What could be causing this?

Dizziness and lightheadedness during the second trimester of pregnancy are quite common and usually related to physiological changes during pregnancy.
As the fetus develops, the mother's blood volume increases, and blood dilution may lead to relative anemia, which can cause dizziness. Secondly, changes in hormone levels during pregnancy, especially increased progesterone, can cause blood vessels to dilate and blood pressure to drop, affecting blood supply to the brain and causing dizziness.
Special hormones produced by the placenta cause systemic small artery spasms, elevated blood pressure, and cerebral vascular spasms and ischemia, leading to dizziness. Timely medical treatment is required, using antihypertensive medications such as nifedipine tablets or labetalol hydrochloride tablets.
Prolonged fasting or insufficient nutrient intake by the pregnant woman can lead to decreased blood glucose levels, causing symptoms such as dizziness and palpitations. Pregnant women are advised to maintain good eating habits and carry quick-sugar foods such as candy.
In daily life, pregnant women are advised to ensure adequate rest and avoid prolonged standing or rapid changes in body position; maintain a balanced diet and timely supplement necessary nutrients; regularly monitor blood pressure and hemoglobin levels, and seek treatment under a doctor's guidance when necessary.
