[Effect of Roux-en-Y gastric bypass on quality of life in non-obese patients with type 2 diabetes mellitus].

OBJECTIVE

To observe the impact of Roux-en-Y gastric bypass on quality of life in non-obese patients with type 2 diabetes mellitus.

METHODS

Thirty-seven non-obese patients with type 2 diabetes mellitus who underwent Roux-en-Y gastric bypass were prospectively studied. A 36-item short form healthy survey questionnaire(SF36), the diabetes treatment satisfaction questionnaire(DTSQ), and quality of life scale for patients with type 2 diabetes mellitus(DMQLS) were used to evaluate the quality of life for all the non-obese patients with type 2 diabetes mellitus preoperatively and 12 months postoperatively.

RESULT

The blood glucose and lipid indexes were significantly decreased after operation(all P<0.05). SF36 showed the physical and mental synthesis scores at 12 month after operation were 74.6±18.3 and 79.8±14.9 respectively, higher than those at one week before operation(54.9±15.1 and 56.4±17.8, both P<0.01). DTSQ showed treatment satisfaction score was increaced significantly after operation(29.2±7.1 vs. 15.4±5.6, P<0.01). The quality of life evaluated by DMQLS, was also significantly improved(P<0.01).

CONCLUSION

Roux-en-Y gastric bypass can significantly improve the quality of life for non-obese patients with type 2 diabetes mellitus.
