Question of the week
Postpartum hypertension is a common complication that can appear weeks after delivery, even in patients with no prior history.
While blood pressure often normalizes within days, delayed-onset hypertension affects a significant number of patients and requires careful evaluation. But treatment isn't straightforward— clinicians must weigh additional considerations like breastfeeding safety, screening for secondary causes, and determining when specialist referral is appropriate.

Post:
32 YOF, G1P1, presents to clinic 4 weeks postpartum with new-onset elevated blood pressure noted at her OBGYN routine check: 160/102 mmHg. She had an uncomplicated vaginal delivery at term and no prior history of HTN during or before pregnancy. She reports mild bilateral pedal edema but denies headache, visual changes, epigastric pain, or shortness of breath. No proteinuria on dipstick.
She is breastfeeding and reports good infant bonding and recovery otherwise. No family history of early cardiovascular disease or autoimmune conditions.
Vitals: HR 82, afebrile, BP 157/103
Labs: creatinine 0.9, platelets 190k, AST/ALT WNL.
Questions for consult
1. Do you screen for secondary causes in otherwise low-risk patients with delayed postpartum hypertension?
2. What is your approach to selecting first-line antihypertensives in breastfeeding patients?
3. Do you involve cardiology or nephrology early in cases of persistent postpartum hypertension, or reserve referral for those with refractory or severe features?
Comments
Key takeaways about postpartum hypertension management:
- Screen for secondary causes when hypertension persists
Routine screening isn’t needed for all low-risk patients, but if blood pressure stays high beyond the postpartum window or looks atypical, a full workup is recommended. - Choose antihypertensives safe for breastfeeding
First-line options include calcium channel blockers and beta blockers, with ACE inhibitors like enalapril or captopril also considered safe. Start low and titrate slowly. - Refer specialists for persistent or severe cases
Cardiology or nephrology involvement is usually reserved for refractory hypertension or when abnormal labs or end-organ damage appear.
Family Practice
"1. I would do labs looking at renal function. I would start her on a low-dose calcium channel blocker and have her get a home blood pressure device and have her monitor her blood pressure first thing in the morning, in the afternoon, and in the evening. Have her log those and do a follow-up in one week. I would get a cardiologist involved if her blood pressure continues to run high.
2. I would use a low-dose calcium channel blocker and monitor it and increase the dose if needed slowly.
3. I would get a cardiologist involved if her blood pressure remained high on a calcium channel blocker before switching her to any other anti-hypertensive meds."
Family Practice
"1. It would be good to screen with a full blood and urine workup as above and check if the patient is on any NSAIDS.
2. Consider using enalopril or captopril if breastfeeding.
3. I would probably involve them if hypertension is persistent and/or the workup warrants further consultation."
Nurse Practitioner
"1. I would start meds, and if no improvement or not resolving, then I would screen for secondary causes.
2. Peocardia XL 30mg and increase until maximized. Can then add labetalol if needed.
3. I would wait until refractory or severe features."
Family Practice
"1. Yes, if the BP remains elevated beyond the expected postpartum window or has an atypical presentation, it is best to screen for secondary causes such as renal disease, thyroid, medication adverse effects, etc.
2. Needs to be safe for breastfeeding, such as nifedipine.
3. It would be appropriate to involve specialists in persistent postpartum HTN if you have discovered abnormal labs, signs of end-organ damage, or have diagnostic uncertainty."
Family Practice
"1. Labs have already been completed. Since her BP elevation is most likely related to recently being postpartum, no further workup is needed yet.
2. A beta blocker or CCB could be tried first line.
3. If BP is remaining elevated for more than 3 months after medications have been started, secondary causes should be evaluated and consultation requested."
