Specializes in Neurology

Dizzy: Usually dizziness on standing equals not enough blood flow getting to the brain...Not unusual when mild. Gravity pulling it down to the legs and not enough pressure to go upward from heart to brain against gravity. Bending over...?Related to cardiac output obstruction, aortic valve disease. Common dizziness on standing causes: dehydration, BP meds, neuropathy, parkinson's.
