Brief Summary:
The World Health Organization (WHO) statistics, in 2008, there were more than 1.4 billion adults, aged 20 and older, and were overweight. Of these over 200 million men and nearly 300 million women are obese. Body Mass Index (BMI) more than 30 is considered as obese and increasingly bariatric surgery is the commonest way used nowadays to lose weight. Moreover, surgery will influence many other health factors and parameters. Many studies prove the improvement of metabolic and psychological status of patients post bariatric surgery. In addition, many vitamins will be affected and should be replaced. This research study is continuation (PART 2) of previously approved study (approval: 13/54). Brief findings of the study are attached. Our aim in this part of the study to assess long term the impact of bariatric surgery on metabolic, nutritional and quality of life status on patients post bariatric procedure of at least 12 months post-surgery follow up. As we noted in our previous initial study that there is significant loss the collection of the data due to "no show" for proper follow up routine care. Previously it was approved to consent patients by phone calls and extract information regarding Quality of Life (QoL) post-surgery. This will be replaced by seeing the patients in the outpatient clinic and providing the necessary information and consent.
