Iodine deficiency is higher in morbid obesity in comparison with late after bariatric surgery and non-obese women.

Background: Iodine deficiency and obesity are worldwide-occurring health problems. Our purpose was to investigate the relationship between morbid obesity and iodine status, including subjects who lost weight after bariatric surgery.

Methods: Ninety morbidly obese women, 90 women with at least 18 months follow-up after bariatric surgery, and 45 healthy non-obese women were recruited.
