Abstract:
Postprandial blood pressure reductions have been observed in frail elderly individuals. This study evaluated blood pressure and heart rate changes in 10 healthy elderly subjects at intervals before and after a morning meal. Subjects did not exhibit significant reductions in systolic blood pressure or increases in heart rate over time, rather, such changes were due to variation within subjects. They did not exhibit significant changes in diastolic blood pressure. Age, health, and meal choice may have influenced results. Further research will determine which groups of elderly are most at risk for postprandial blood pressure reductions and consequently at risk for injury from falls due to dizziness and syncope.

Factors affecting Blood pressure
Physiological Factors:
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
