NCT03458533

Brief Summary

This study aims to identify new morphological and quantitative magnetic imaging parameters of pituitary gland and sellar region in overweight and obese patient at baseline and after 3 years, dividing patients in 3 groups (weight loss through diet and lifestyle changes, weight loss through bariatric surgery, no weight loss)
