icd 10 orthostatic hypertension

Orthostatic hypertension, also referred to as postural hypertension, is characterized by an abnormal increase in blood pressure when a person shifts from a seated or reclined position to a standing one. This alteration in blood pressure can result in symptoms such as dizziness, vertigo, and potentially syncope. Typically, upon standing, blood is drawn to the lower limbs by gravity, causing a minor drop in blood pressure. The body counters this by increasing the heart rate and constricting blood vessels to maintain stable blood pressure. In individuals with orthostatic hypertension, however, this regulatory response may be hyperactive, leading to an excessive rise in blood pressure.

The etiology of orthostatic hypertension can encompass dysfunction of the autonomic nervous system, dehydration, adverse effects of certain medications like diuretics, endocrine disorders such as pheochromocytoma, or other underlying health conditions. Diagnosis often relies on blood pressure measurements, particularly noting variations in blood pressure across different body positions. Management strategies may involve lifestyle modifications (e.g., increasing fluid intake, avoiding rapid positional changes), adjustments to pharmacological regimens, or targeted treatments for the root cause.

For those with orthostatic hypertension, it is crucial to avoid rapid standing in daily activities, maintain adequate hydration, and adhere to the physician's recommendations for ongoing monitoring and treatment plan adjustments. In cases of severe symptoms or inadequate blood pressure control, immediate medical evaluation and treatment strategy reassessment are imperative.
