Early diastolic notch is observed at the start of the second trimester and most often disappears by 24-26 weeks of gestation. It is the result of raised peripheral vascular resistance. Persistence of the notch after 26 weeks may indicate insufficiency of uterine blood flow due to the increased resistance of the spiral arteries of the uterus
leading to their insufficient dilatation. You need to repeat the scan after a couple of weeks to review the situation. There is no need for worry now and you can continue with your usual medication. Take rest for at least 2 hours during the day and 8 hours in the night, preferably in the left lateral position to improve uterine blood supply. Avoid salty, spicy and oily foods. Have regular check up. Take fresh fruits and vegetables. The mode of delivery cannot be predicted now. Please consult your doctor for further advice. Wish you safe motherhood.
