Abstract
Introduction. Obesity is among the newest health matters that human beings are struggling with. Length of bypassed intestine is important in achievement of most weight loss and least nutritional and absorptive disorders. This study has aimed to assess short-term metabolic and nutritional effects of laparoscopic mini-gastric bypass/one anastomosis gastric bypass (MGB/OAGB) with a loop bypass length of 180 centimeters (cm) and compare these factors among patients with a body mass index (BMI) of 40–45 and 45–50 kilograms per square meter (kg/m2). Methods 25 patients were put in group 1 (BMI = 40–45 kg/m2) and 25 patients in group 2 (BMI = 45–50 kg/m2). Patients' BMI, postoperative weight, excess weight loss, and laboratory tests including fasting blood sugar (FBS), lipid profile, serum iron (Fe), ferritin, total iron-binding capacity (TIBC), 25-OH vitamin D, vitamin B12, liver function tests, and albumin were recorded preoperatively and within 3- and 6-month follow-up. Results Weight loss and BMI reduction was significantly more in patients with higher BMI level (P=0.007), and excess weight loss was higher in patients with lower preoperative BMI level (P=0.007), and excess weight loss was higher in patients with lower preoperative BMI level (P=0.007), and excess weight loss was higher in patients with lower preoperative BMI level (Conclusion Based on this study, 180-cm intestinal bypassed length works for patients with a BMI level of 40–45 and 45–50 kg/m2, according to their significant decrease in weight, BMI, and improving glycolipid profile.
Highlights
Obesity is among the newest health matters that human beings are struggling with
As it can be seen that fasting blood sugar (FBS), TG, total cholesterol (TC), low-density lipoprotein cholesterol (LDL), AST, and ALT have a down slope trend, which statistics showed significant changes in some of them; other factors like iron, ferritin, vitamin D, and vitamin B12 had been decreased at first and increased afterwards and none of them were significant statistically
We aimed to compare whether more obese patients need longer intestinal bypass length or 180 cm which is a widely used and confirmed intestinal bypass length that works for them too according to their nutritional, metabolic, and weight loss changes following MGB/OAGB

Obesity is among the newest health matters that human beings are struggling with today. It has been confirmed that the laparoscopic mini-gastric bypass/one anastomosis gastric bypass (MGB/OAGB) as an easier technique of gastric bypass is even more effective than the classic technique, RYGB [7, 8]
