Summary

The number of obese is increasing rapidly. Bariatric surgery is used to a greater and greater extent as treatment of obesity to obtain a greater and more permanent weight loss. The currently most commonly used surgical method is the gastric bypass (RYGB), which so far has proved to be the most effective way to achieve a greater and more permanent weight loss, reduction and maybe even elimination of many of the obesity-related health complication (diabetes, sleep apnea, pain due to osteoarthrosis etc.).

Bariatric surgery, including RYGB is also associated with medical and nutritional complications. This will be a natural consequence of the fact that the food bypasses virtually the entire ventricle and 100-150 cm of the upper part of the small intestine after a RYGB. Therefore, problems with uptake of for example B12, iron, folate, thiamin, fat-soluble vitamins (Vitamins A, D, E and K) copper, zinc and selenium are expected. In the light of this, it is decided that all RYGB operated patients must take vitamin B12, iron and vitamin D substitution. In spite of this, many develop various nutritional problems after RYGB. In addition to these nutritional complications are complications such as hypoglycaemia and gallstone attacks after RYGB.

Nevertheless there is no comprehensive inventory of the occurrence of nutritional complications after bariatric surgery neither in Denmark nor in an international context. Thus there is no consensus on an optimal postoperative prevention of complications. An overview of the occurrence of these problems will be important for assessing and determine the indications for bariatric surgery as well as to optimize the prevention of complications.

To enlighten this we will conduct a questionnaire survey of complications such as pain, dumping and hypoglycemia after RYGB. Moreover we will the quality of life after RYGB operation. We will invite 3500 RYGB operated patients the Central Denmark Region who have been operated 2006-2011.
