Patients with elevated blood pressure after cesarean section, if the systolic blood pressure is greater than or equal to 140mmHg and/or diastolic blood pressure is greater than or equal to 90mmHg, this situation is currently an indication for treatment. It is recommended that patients pay attention to a low-salt, low-fat diet, regular work and rest, avoiding exertion and late nights, and combining appropriate exercise and weight loss. If the patient fails to control her blood pressure through lifestyle intervention and improvement, and is currently breastfeeding, she can choose to apply nifedipine tablets, methyldopa or labetalol to further lower her blood pressure. Labetalol or methyldopa should be adjusted according to the situation of elevated blood pressure, the frequency of daily oral medication and the dose, relatively speaking, the effect of nifedipine will be more potent, but not as safe as methyldopa.
