Summary
Brief summary (as posted)
The goal of this randomized controlled trial is to learn if a low-sodium diet improves postpartum blood pressure control in adults who were diagnosed with a late-onset hypertensive disorder of pregnancy. The main questions it aims to answer are: * Does a low-sodium diet lead to decreased mean arterial blood pressure (MAP) on postpartum day 7? * Does a low-sodium diet lead to a decreased MAP on postpartum day 3? * Does a low-sodium diet reduce 30-day hospital readmissions for hypertension-related indications? Participants will be provided with meals for 7 days following their delivery. The experimental diet will contain less than 2000mg of sodium daily. The control diet will have variable sodium content with no restrictions. Participants will be asked to record the food they consume over the study week. They will also be provided with a blood pressure (BP) cuff and asked to record their BP at least once daily.

Primary outcomes (1)
- measure
- Difference in Mean Arterial Blood Pressure (MAP) on Postpartum Day 7
- timeFrame
- 7 days following delivery
- description
- Participants in both groups will check their blood pressure (BP) at least once daily with a provided cuff. On postpartum day 7, the average MAP for each participant will be calculated from all available BP values. The difference in MAP on postpartum day 7 between the experimental and control groups will serve as the primary outcome.
