Hello. I have gone through your question and understand your concern. Patients with postpartum hypertension [high blood pressure after delivery] that persist after delivery are usually suggested to start with antihypertensive drugs. As you clearly mention of having a healthy lifestyle and no addictions with history of endometriosis for quite a while; I am thinking in terms of secondary hypertension due to endometriosis along urinary tract. Intra luminal endometriosis if present in urinary tract can impair renal function thereby causing hypertension in some patients. In such case, Ureteroscopic biopsy can confirm diagnosis followed by surgical resection which resolves hypertension. If renal parameters are not impaired then high blood pressure is to be treated as regular hypertension [de novo] with appropriate antihypertensive drugs and low sodium intake. Hope your concern is answered. Thank you.
