Post-prandial hypotension.
It should be noted that large meals, particularly those high in carbohydrates or associated with alcohol, can magnify the drop in blood pressure. Elderly persons are more susceptible to these effects [8]. If symptoms are more prominent postprandially, then measurement of orthostatic blood pressures before and after meals should be considered.
Diet.
In patients with OH/nOH, normal sympathetic activity cannot compensate for blood pooling within the splanchnic circulation after eating. With nOH, sympathetic vasoconstrictor nerve activity is deficient and many patients become severely hypotensive within 2 h of eating [8, 68].
It is important to recognize this problem because treatment of OH/nOH can diminish symptoms post-meal. Patients can be asked to measure their blood pressure before and 30 min after a high carbohydrate meal. In individuals with postprandial hypotension, smaller, more frequent meals are recommended [69, 70].
There is also some evidence that a low glycemic diet may have a beneficial effect on the symptoms of OH/nOH [68, 71, 72]. Finally, postprandial hypotension can be reduced with caffeine [73] or acarbose [74].
