Full description

Target group: patients who have scheduled a gastric bypass in UZ Leuven. Patients will be questioned preoperatively and one, three, six and twelve months after gastric bypass surgery. Each assessment will be performed during a routine consultation.

The following aspects will be investigated:

Medication The investigators have composed a questionnaire to examine which drugs the patients use, adherence, information received about medication and from whom,...
Clinical parameters Every consultation, concentrations of hemoglobin, iron, hepcidin, vitamin B12,.... and a 24h urine collection to determine calcium excretion will be collected.
Dietary intake The investigators will ask patients to keep a food record during two non-consecutive days preceding each consultation. In this food record patients have to note all consumed foods and beverages with the right/estimated amounts. This makes it possible to see the changes of the composition of the meals before and after RYGB.
