What are the reasons for dizziness, palpitations, and tinnitus during pregnancy?

Patient's question:

No

Doctor's answer:

Many women experience dizziness, fatigue, and a sense of lethargy or extreme tiredness in the early stages of pregnancy, feeling generally uncomfortable. Dizziness in the early stages of pregnancy is caused by a drop in blood pressure after conception, leading to insufficient blood supply to the brain and resulting in dizziness. This is a temporary condition of inadequate brain blood supply, which will gradually improve as the heart rate increases and cardiac output rises. Typically, it normalizes by the seventh month of pregnancy.
