supine hypertension

Supine hypertension refers to the condition where an individual's blood pressure rises when lying flat on their back and normalizes or decreases when sitting or standing. This phenomenon is likely linked to several factors, including dysregulation of the autonomic nervous system, increased cardiac output, and alterations in vascular resistance.

In examining the etiology of supine hypertension, the primary consideration is the imbalance within the autonomic nervous system. Overactivity of the sympathetic nervous system can result in tachycardia and vasoconstriction, which in turn can elevate blood pressure. Additionally, an increase in cardiac output is a significant contributor, as a higher stroke volume directly leads to a rise in blood pressure. Changes in vascular resistance are also crucial; the release of substances like angiotensin II can induce vasoconstriction and consequently raise blood pressure. In certain instances, hypersensitivity to adrenergic receptors may also contribute to elevated blood pressure.

For individuals with supine hypertension, it is advisable to monitor blood pressure regularly and to make lifestyle modifications under medical supervision, such as adopting a balanced diet, engaging in moderate exercise, and ensuring adequate sleep. Compliance with prescribed medication is essential, and self-adjustment of medication dosage or discontinuation is not recommended. Should blood pressure remain elevated or be accompanied by additional symptoms, immediate medical consultation and professional treatment are imperative.
