Nutritional Intake of Post Bariatric Surgery Patients in an Urban Population

Obesity increases morbidity and mortality rates and decreases the quality of life. Surgical approach of weight management induces sustained weight loss contributed by the reduction in gastrointestinal anatomy with alteration in metabolic physiology and dietary habits. With restricted eating capacity, having nutritionally balanced diet may be challenging. Thus nutrition plays the key role in overall well being of the post bariatric patients. A facility based retrospective study was conducted at Apollo Hospitals, Bangalore, India, on 31 bariatric patients, between the duration of 2014 to 2016. A structured questionnaire was used to elicit information on socio demographic information, anthropometry, dietary history (food Frequency, 24 hrs recall method), medical conditions& physical activity level. The data was tabulated and appropriate statistical tests were applied. On analyzing, a significant weight loss of 36.16kgs �15.97 kgs was observed with 12.64 kg/m2 reduction in BMI. The observed population had sub optimal protein intake of 41.04g �13.36 g, additionally they were deficient in vital micronutrients such as Calcium, Iron& Fiber. Pre Operative BMI significantly associated with post surgery weight loss (p=0.008). Energy consumption negatively correlated with the observed weight loss ( r = - 0.060).
