NCT03048708

Brief Summary

This study is expected to provide novel data regarding potential structural and functional changes of the thyroid gland in morbidly obese adults following significant weight loss through bariatric surgery. These data will complement evidence from epidemiological studies regarding the association of obesity and alterations in thyroid function. Potentially this study may justify further longer-term studies regarding the effects of weight gain and/or weight loss on the morphology of the thyroid gland and could help to form recommendations regarding follow-up investigations for the thyroid in morbidly obese patients.

Outcome Measures

Primary Outcomes (1)

  • Changes in thyroid morphology and thyroid function tests in morbidly obese patients following significant weight loss after bariatric surgery

    Measurement of thyroid ultrasound (grey scale assessment, volume, echogenicity) and thyroid function tests (free T4, free T3, TSH and rT3) at baseline and at least 3 months after surgery when relevant weight loss is achieved

    > 3 month or when relevant weight loss has been achieved

Study Arms (2)

Obese patients treated with bariatric surgery

EXPERIMENTAL

Patients with morbid obesity who were eligible for and willing to have bariatric surgery performed

Procedure: Bariatric surgery

Obese patients not treated with bariatric surgery

NO INTERVENTION

Age and BMI matched patients with morbid obesity who either were not eligible for or were not willing to have bariatric surgery performed - no sufficient number of matched patients has completed the study; the arm of obese patients not treated with bariatric surgery has been discarded for the purpose of the analyses

Interventions

patients who had received treatment with bariatric surgery for medical reasons

Obese patients treated with bariatric surgery
