Uterine Artery Doppler Changes Prior and After Breastfeeding

Study Overview
=================
Brief Summary
-----------------
We aim to determine whether there are any differences in the UtA doppler measurements in postpartum women prior and right after breastfeeding.

Detailed Description
-----------------
There is emerging evidence linking abnormal UtA Doppler indices in the postpartum period as a risk factor for developing future cardiovascular disorders. Thus far, no study considered the postpartum physiology itself as a possible confounder. If one wishes to draw conclusions about future cardiovascular risk, the role of oxytocin as a confounder must be determined. In the current study, we aim to determine whether oxytocin, physiologically produced during breastfeeding, has an effect on the UtA Doppler measurements in the postpartum period.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Prior to breastfeeding - cross section<br>Measurements of the UtA doppler postpartum ultrasound will be carried out twice for each eligible woman on the second day postpartum. The first measurement will take place just prior to a planned breastfeeding. The second measurement will be followed immediately (within 10 min) after the breastfeeding session. | Diagnostic Test: Postpartum ultrasound<br>* Measurements of the UtA doppler ultrasound will be carried out twice for each eligible woman on the second day postpartum. The first measurement will take place just prior to a planned breastfeeding. The second measurement will be followed immediately (within 10 min) after the breastfeeding session.<br>|
| After breastfeeding - cross section<br>Measurements of the UtA doppler postpartum ultrasound will be carried out twice for each eligible woman on the second day postpartum.
