Women with elevated blood pressure during breastfeeding can be treated as follows: 1. Patients with mild hypertension should make lifestyle adjustments and improvements, and it is recommended that patients have a low-salt, low-fat diet, exercise and regular rest as much as possible, which can help reduce blood pressure; 2. Moderate or even severe hypertension needs to be treated with antihypertensive drugs, and the preferred antihypertensive drugs during breastfeeding are labetalol and nifedipine antihypertensive drugs; 3. Heart rate and blood pressure need to be monitored during the antihypertensive process, and ambulatory blood pressure monitoring can be performed to assess the overall blood pressure fluctuations over 24 hours to facilitate the formulation of treatment plans.
