Diagnosing Orthostatic Hypotension (Postural Hypotension)
Orthostatic hypotension, also called postural hypotension, is a sudden drop in blood pressure that happens when you stand up too quickly. It's more common in older adults and while this condition is usually mild and short-lived, it can lead to complications like dizziness, blurry vision, or fainting.
To diagnose orthostatic hypotension, healthcare providers may perform several examinations, screening tests, and procedures to help confirm the diagnosis and determine the severity of the condition. Here are some of the common tests and procedures used:
- Physical examination: During a physical exam, healthcare providers look for physical signs of a medical problem, such as pain, swelling, or the presence of masses within the body.
- Blood pressure monitoring: Blood pressure measurements are taken in different positions to assess changes in blood pressure when switching from lying down to standing up. This is done to identify drops in blood pressure that occur with orthostatic changes.
- Blood test: Doctors may recommend blood tests to check for underlying conditions that could cause orthostatic hypotension. These tests involve taking a blood sample to measure various health markers and help identify potential issues affecting blood pressure.
- Tilt-table test: This test can help assess the response to changes in position, like moving from lying down to standing up.
- Balance assessments: Assessments like the Berg Balance Scale can help evaluate balance problems associated with orthostatic hypotension.
- Falls questionnaire: A questionnaire that can provide information about any history of falls related to postural changes.
- Symptom questionnaires: Questionnaires like the Dizziness Handicap Inventory (DHI) can measure how symptoms like dizziness affect daily life.
- Autonomic function tests: These tests check how well the autonomic nervous system is working and can help detect issues related to orthostatic hypotension.
These examinations, tests, and procedures help healthcare providers confirm a diagnosis of orthostatic hypotension by identifying changes in blood pressure with positional changes and ruling out other potential underlying causes.
Several specialists may be involved in diagnosing orthostatic hypotension:
- Primary care providers often begin the diagnosis process and refer patients to specialists if needed.
- Cardiologists focus on heart and blood vessel issues.
- Neurologists check for nervous system disorders that might affect blood pressure.
- Endocrinologists address hormonal imbalances impacting blood pressure.
- Nephrologists manage kidney-related conditions that affect blood pressure control.
Remember, it's important to consult with a healthcare provider for an accurate diagnosis and appropriate management. They will determine which examinations, tests, or procedures are necessary based on your specific symptoms and medical history.
