Dear Editor:

We would like to congratulate Komorniak et al. for their work regarding homocysteine metabolism and its changes after bariatric surgery [1].

Obesity has become a major global health challenge and its prevalence is alarmingly increasing [2, 3]. Bariatric surgery is widely accepted as the best treatment for obesity [4], and trends have shown an increased popularity of sleeve gastrectomy (SG) comparing with the Roux-en-Y gastric bypass (RYGB) [4]. Nevertheless, it is more frequent to find reporting on nutritional status in RYGB than in SG studies. In the study of Komorniak et al., although homocysteine levels were assessed after bariatric surgery, only 73 SG patients were included (and 1190 patients for RYGB) [1].

Obesity is consistently and strongly related with a higher risk of CVD incidence and mortality [5], and homocysteine has been recognized as an independent risk factor for cardiovascular diseases [6]. Thus, changes in homocysteine levels after bariatric surgery may...
