Anaemia After One Anastomosis Gastric Bypass
Many thanks for your kind invitation to comment on this letter in response to the article  published recently in Obesity Surgery. First of all, it is important to understand what Bailly et al.  found in their study. They found that amongst those who were hospitalised in France, for one reason or other, and had undergone a primary bariatric procedure between 2008 and 16, anaemia due to micronutrient deficiency was more likely to be listed as the main or related diagnoses in those who underwent a gastric bypass (GB) compared to those who underwent a sleeve gastrectomy (SG). Authors of this letter point out that others  have found anaemia rates to be higher with SG than GB, Roux-en-Y gastric bypass (RYGB) in particular. They further contend that the results might be due to the possibility that GB cohort in the study by Bailly et al.  includes a large number of patients who underwent one anastomosis gastric bypass (OAGB)—an increasingly popular procedure in...
