If a pregnant woman suddenly gets dizzy and light-headed, she must have her blood pressure measured and her urine tested for urine protein. Next, kidney function needs to be checked. The most common form of dizziness and blurred vision is hyperemesis, and the patient can be accompanied by generalized swelling, with the lower extremities being the heaviest. In addition, hypertensive headache, dizziness and blurred vision must be treated in hospital if it is hyperemesis gravidarum. Because hyperemesis gravidarum can cause significant generalized swelling with large amounts of proteinuria, renal insufficiency can occur, sometimes requiring termination of the pregnancy. It is recommended that you must go to the hospital if you have dizziness and blurred vision.
