From the Research
To diagnose postprandial hypertension, patients should have their blood pressure measured before and after meals, specifically looking for an increase of 20 mmHg or more in systolic blood pressure within two hours after eating, as this condition is associated with increased risk of falls, syncope, stroke, and cardiovascular events 1.
Diagnosis of Postprandial Hypertension
The diagnosis of postprandial hypertension involves measuring blood pressure before and after meals to identify any significant increases in systolic blood pressure.
- Home blood pressure monitoring can be a useful tool in diagnosing postprandial hypertension, with patients recording their readings before meals and at regular intervals afterward, particularly noting any symptoms like dizziness, falls, or syncope that occur post-meal 2.
- Ambulatory blood pressure monitoring over 24 hours can also provide valuable data by capturing multiple post-meal periods, helping to identify patterns of blood pressure fluctuations throughout the day 3, 1.
Key Considerations
When diagnosing postprandial hypertension, it is essential to rule out other causes of blood pressure fluctuations, including:
- Medication effects
- Autonomic dysfunction
- Endocrine disorders Postprandial hypertension occurs primarily due to inadequate peripheral vasodilation after eating, when blood normally pools in the splanchnic circulation, and is more common in elderly individuals and those with hypertension, diabetes, or autonomic dysfunction 4.
Monitoring and Management
Regular monitoring of blood pressure and adjustment of treatment as necessary can help manage postprandial hypertension and reduce the risk of associated complications, such as falls, syncope, stroke, and cardiovascular events 5.
