I95.1

Clinical Causes: Dehydration due to reduced fluid intake or excessive fluid loss from sweating, vomiting, or diarrhea Medications such as diuretics, blood pressure medicines, antidepressants, or medications for Parkinson's disease Autonomic nervous system disorders that impair blood pressure regulation Prolonged bed rest or immobility Heart problems such as arrhythmias or heart failure Endocrine issues like adrenal insufficiency or thyroid problems Aging, which affects blood vessel elasticity and autonomic function Nerve damage from conditions such as diabetes (diabetic autonomic neuropathy) Blood volume depletion from bleeding or severe infections

Key Symptoms: Dizziness or lightheadedness upon standing up Blurred vision during positional changes Weakness or fatigue Fainting or syncope Nausea Palpitations or a feeling of the heartbeat pounding Confusion or difficulty concentrating in severe cases

Diagnosis Path: Diagnosis of orthostatic hypotension involves measuring blood pressure and heart rate while the patient is lying down, sitting, and standing. The clinical criteria typically used are a drop in systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg within three minutes of standing. Additional tests may include autonomic function evaluations, blood tests, and cardiovascular assessments to identify underlying causes.

Treatment Protocols: Management of orthostatic hypotension focuses on addressing underlying causes and alleviating symptoms. Strategies include lifestyle modifications such as increasing fluid and salt intake, wearing compression stockings, and avoiding rapid changes in posture. Medications may be prescribed in some cases to help maintain blood pressure, but these are tailored to individual needs. Regular monitoring and collaboration with healthcare providers are important for effective management.
