Management of Hypertension in the Obese Pregnant Patient

PURPOSE OF REVIEW: To evaluate recent developments in the management of hypertension in obese pregnant women. RECENT FINDINGS: The mainstay of management targets prevention of hypertension with preconception counselling, entering pregnancy with a lower BMI, limiting weight gain, and taking low-dose aspirin to prevent pre-eclampsia from before 16 weeks’ gestation. There are conflicting results regarding the use of metformin in reducing hypertensive disease, but there is a high probability that it has a role to play. Clinical trials are in progress examining the use of statins in preventing pre-eclampsia, with promising results from pre-clinical trials. Home blood pressure monitoring may be helpful in diagnosing and monitoring the control of hypertension. SUMMARY: The most protective interventions against hypertensive disease in obese pregnant women are entering pregnancy at a lower BMI, avoiding inter-pregnancy weight gain, and taking low-dose aspirin during pregnancy. Further research is needed around the use of metformin, statins, and home blood pressure monitoring.
