Introduction:Obesity is a medical case in which extra body fat has stored to the extent that it may have a harmful effect on health. People are generally measured obese when their body mass index (BMI), ameasurement obtained by dividing aperson's weight by the square of the person's height, is over 30 kg/m2, with the range 25-30 kg/m2 defined as overweight. Some East Asian countries use lower values. Aim of the work: Find out the prevalence of overweight and obesity among female students in Sohag University, and identify important risk factors. Patients and Methods: Cross sectional study, included a sample of female students aged 17-25 in the selected faculties in Sohag University, the study was carried out in Faculty of Medicine, Faculty of Nursery and Faculty of Education in Sohag University, the questionnaire was divided into five parts, the demography, dietary habits, physical activity, perceptions of body weight and beliefs of obesity and the record of self-reported and actual anthropometric body measurements. Results: Overweight and obesity were prevalent among the our study subjects as the prevelance was 38.5%, lack of physical activity, soft drink consumpton and marital status were significantly associated with obesity, our students preferred dairy products and fatty foods over vegetables and fruits. In addition, their "lack of time" was the most frequently mentioned barrier to eating a healthy diet and engaging in regular exercise. Life style modification is important to improve healthy habits earlier in life. Conclusion: Overweight and obesity were prevalent among the our study subjects as the prevelance was 38.5%.

Bariatric surgeries involvement in treating comorbid obesity is growing fast. Since it was first approved as a treatment for those who had previously failed to reduce weight through conventional ways, the usage of bariatric surgery has significantly increased. The body mass index is frequently used in clinical practise to identify obesity, which is generally understood to mean having a significant quantity of harmful body fat (BMI). Since the BMI's creation, numerous studies involving sizable populations have shown a J-shaped relationship between the BMI and risk of morbidity or mortality, with a BMI greater than 30 kg/m2 (the definition of obesity in many guidelines) being undeniably linked to an elevated risk of morbidity or mortality. A severe and rapidly expanding global health hazard is the prevalence of morbid obesity. While some people can lose additional weight by making lifestyle changes, participating in exercise programmes, and following diet plans, bariatric surgery is still the treatment of choice for many patients who don't react to other forms of therapy. In terms of weight loss and comorbidity alleviation, bariatric procedures have produced excellent results. However, some issues with bariatric surgery have been reported, including anastomotic leakage, stenosis, haemorrhage, weight regain, and nutritional inadequacies. Due to the Roux-en-Y gastric bypass's poor absorption capabilities (RYGB), ND is an expected complication. Sleeve gastrectomy (SG) and other restraint-inducing operations are also linked to ND. The purpose of this review of the research is to present and discuss the nutritional effects of bariatric procedures and the currently available treatment alternatives.
