Abstract

The impact of laparoscopic sleeve gastrectomy (LSG) on the lactose intolerance (LI) remains unclear. We checked 8 men and 34 women with mean body mass index (BMI) of 43.94 ± 5.89 kg/m2 for LI using hydrogen breath test and clinical examination before LSG and at 3 months postoperation. In addition to appropriate weight loss (34.30 ± 5.51 kg/m2), 1 man and 3 women, who had not LI at starting, were suffered from LI at 3 months postoperation. Among these four patients, the most and least LI was seen in women who had the lowest and highest percentage of excess BMI loss. It seems LSG can induce LI which must be monitored in postoperative follow-ups.
