PURPOSE: Ghrelin may lead to weight gain by appetite stimulation. This prospective study investigated the association between weight loss and the ghrelin levels in patients after gastrectomy. METHODS: Thirty-three males and eight females were enrolled in the study. The average age was 66 years. Measurements of the serum ghrelin level and an appetite questionnaire were performed preoperatively and at one, three, six and 12 months postoperatively. RESULTS: The preoperative serum total ghrelin level was 51.6 ± 31.9 (fmol/ml ± SD), and that at one, three, six and 12 months postoperatively was 16.9 ± 9.0, 21.2 ± 16.0, 28.0 ± 19.1 and 29.6 ± 20.6 (fmol/ml ± SD), respectively. The appetite score was 2.02 ± 1.09 points at 1 month, and increased significantly to 2.61 ± 1.00 by 12 months. CONCLUSIONS: The ghrelin levels were reduced after gastrectomy and did not recover by 12 months postoperatively. Further studies are needed to evaluate these results as the basis of a therapeutic trial.
