N2 - Recently, it has been proposed, that the blood pressure (BP) lowering effect of gastric bypass surgery not only is explained by the obtained weight loss, but that the anatomical rearrangement of the gut after 'malabsorptive' surgical techniques, such as the laparoscopic Roux-en-Y gastric bypass (LRYGB), may affect BP through a change in a putative 'entero-renal' axis. If so one could anticipate a reduction in BP even before a noticeable weight loss was obtained. The purpose of the present study was to investigate the very early BP response to LRYGB surgery. Ten severely obese hypertensive (mean BMI 40.8 kg/m2) and 10 severely obese normotensive (mean BMI 41.7 kg/m2) patients underwent 24-h ambulatory blood pressure measurements (24 h ABPMs) before LRYGB and again day 1 and day 10 after LRYGB. No change in 24 h BP was observed day 1 after LRYGB. Day 10 after surgery both hypertensive and normotensive patients demonstrated a significant 12.6 mmHg and 9.5 reduction in systolic BP (SBP), respectively. Mean arterial pressure (MAP) decreased by 8.3 and 5.4 mmHg. At day 10 postoperatively, a weight loss of 7.9 kg in the hypertensive patients and 7.0 kg in the normotensive patients was observed. The reduction in BP after LRYGB takes place before any substantial weight loss has occurred. The reason for this remains speculative, but obese hypertensive patients may clearly benefit from the operation even if the goal of achieving 'normoweight' is not obtained.
