Dizziness is a very common symptom of pregnancy. These are not unusual and sometimes end up with fainting. When you are pregnant, the cardiovascular system undergoes substantial changes: the pulse is accelerated, the heart beats more blood per minute, and the amount of blood in the body increases by 40-45%.
What are the causes?
The main cause of dizziness in pregnancy is the hormones that cause relaxation and enlargement of blood vessels. They contribute to the increase of blood flow to the baby, but it slows down the reverse circulation of blood, on the way back to the heart and organs. This causes a lower blood pressure than usual, which reduces blood flow to the brain, causing dizziness.
These can also be caused by low blood sugar, which occurs during the body's adaptation to new changes in pregnancy. Women who suffer from anemia or varicose veins may experience more of these sensations.
In the second trimester of pregnancy, dizziness can be caused by the growing uterus that begins to put more and more pressure on the blood vessels.
Even late in pregnancy, dizziness may occur. They are caused in this case by the position you are in: for example, if you lie on your back, the baby presses the vena cava and causes the sensation of dizziness.
What should you do when you're dizzy?
There are a few essential things you need to do when you feel like you're faint:
sit down straight away, but easy, to avoid a possible fall and abdominal or head injury;
strip off clothes that put pressure on blood vessels;
open windows and ventilate or take a breath of fresh air;
eat foods high in iron.
