Orthostatic hypotension is associated with a 73% increased risk of falls in older adults.

Study: Beat-to-Beat Blood Pressure Monitoring and Orthostatic Hypotension-Related Falls in Two Cohorts of Older Adults

Older adults who fell had much lower blood pressure when standing up compared to those who didn’t fall, showing that dizziness from blood pressure drops is linked to falling. This supports the idea that orthostatic hypotension makes falls more likely.

Study: Orthostatic Hypotension Is a Risk Factor for Falls Among Older Adults: 3-Year Follow-up.

The study found that older adults whose blood pressure drops quickly when they stand up are 73% more likely to fall in the next year than those whose blood pressure doesn’t drop — exactly what the claim says.

Study: The impact of treatment of orthostatic hypotension on falls in elderly patients admitted to acute geriatric care in a university hospital centre

Older adults with orthostatic hypotension (a drop in blood pressure when standing) were often admitted to the hospital because they fell, and many fell again before leaving — suggesting that low blood pressure when standing is linked to more falls.
