Orthostatic Intolerance: Symptoms and Daily Management
Orthostatic intolerance means symptoms associated with being upright that improve when you sit or lie down. It is a description of a pattern, not a complete diagnosis. Repeated standing dizziness, near-fainting, or difficulty tolerating upright tasks deserves medical assessment so the cause and the safest management can be identified.
For day-to-day planning, focus on where you can pause, how you can shorten demanding tasks, and what your care team wants you to do when symptoms appear. You do not have to prove how long you can remain standing before asking for help.
