Long-term Results After Bariatric Surgery in Type 1 Diabetes Patients

Evaluation of the Long-term Outcome After Bariatric Surgery in Patients With Type 1 Diabetes Mellitus

There is a lack of long-term data on the impact of bariatric surgery in type 1 diabetes (T1D). The aim of this study is to gain long-term outcome data on the effects of bariatric surgery in obese patients with T1D.

This study aims to evaluate long-term data on the effect of bariatric surgery in T1D regarding weight lost, insulin-requirement, and quality of life.

Inclusion criteria are patients who underwent bariatric surgery (Sleeve, One anastomosis gastric bypass, Roux en Y Gastric Bypass) and the presence of T1D prior to surgery. Labor parameters include verification of T1D antibodies, and level of C-peptide. Exclusion criteria is T2D.

In order to obtain a sufficient number of patients for the evaluation, several sites are involved in the acquisition of these specific data.

Inclusion Criteria:

• T1D-specific antibodies
• C-peptide level
• status after bariatric surgery

Exclusion Criteria:

• T2D
• patients without T1D
• patients with T1d without bariatric surgery
