The aim of the project is to further investigate dietary intake with a focus on the interstitial glucose profile in patients before and after bariatric surgery and to map, through a systematic literature review, the effects of preoperative treatment with the low-energy diet on body weight, liver volume, glucose levels and possible side effects of the low-energy diet.
Description
Bariatric surgery (e.g. gastric by-pass and sleeve gastrectomy) for obesity is nowadays an increasingly common treatment method. Due to the anatomical changes of the gastrointestinal tract and the accompanying metabolic and endocrine changes in the patient, appetite, food preferences, portion sizes, beverage intake and absorption of energy and nutrients are affected. At the same time, the surgery itself aims to improve the patient's blood sugar regulation. The aim of three of the four papers in the thesis is therefore to further investigate dietary intake with a focus on the interstitial glucose profile in patients before and after bariatric surgery.
Before bariatric surgery, it is routine that patients are optimised with a low-energy diet to reduce liver volume as this has been shown to facilitate the implementation of the operation. The fourth work therefore consists of a systematic literature review of the effects of preoperative treatment with a low-energy diet on body weight, liver volume, glucose levels and possible side effects of the low-energy diet.
