postprandial hypotension

A decrease in systolic blood pressure of 20 mm Hg or more within 2 hr of the start of a meal. This may cause syncope, falls, dizziness, weakness, angina pectoris, or stroke. This condition occurs most often in older adults and in persons with autonomic failure. Although postural changes may increase the severity of the condition, postprandial hypotension is a different entity from postural hypotension.
