Which condition is NOT a recognized cause of secondary hypertension?

Secondary hypertension is elevated blood pressure that results from an identifiable and potentially treatable underlying cause. Recognized causes include a variety of medical conditions, all of which can significantly impact the body's blood pressure regulation.

Among the options presented, alcohol use disorder is not classified as a recognized cause of secondary hypertension. While chronic excessive alcohol consumption can lead to hypertension, it is considered a lifestyle factor rather than a direct medical condition causing secondary hypertension. This delineation is important because secondary hypertension typically arises from systemic issues, such as hormonal imbalances or structural abnormalities, rather than from lifestyle factors.

On the other hand, pheochromocytoma, which is a rare tumor of the adrenal gland that secretes catecholamines, is known to lead to significant increases in blood pressure due to its effects on vascular tone and heart rate regulation. Intrinsic renal disease is another recognized cause, as conditions such as chronic kidney disease can disrupt the kidney's ability to regulate blood pressure effectively. Additionally, pregnancy can contribute to hypertension through mechanisms such as gestational hypertension or preeclampsia, which are specifically linked to the physiological changes and demands placed on a woman's body during pregnancy.

Understanding these distinctions helps clarify the multifactorial nature of hypertension and the importance of identifying treatable
