Abstract
BackgroundBariatric surgery is effective for the treatment of patients with morbid obesity and type 2 diabetes mellitus (T2DM), for body weight loss and glycemic control. However, in Japan, there has been no previous report of the effectiveness bariatric surgery in a case of morbid obesity associated with acute onset type 1 diabetes mellitus (T1DM), in which pancreatic β-cells were destroyed and endogenous insulin was depleted.Case presentationA 36-year-old woman with morbid obesity and T1DM, diagnosed when she was 6 years, was admitted for bariatric surgery. At her first consultation, she had a body weight of 106.7 kg and a body mass index of 42.2 kg/m2. Her HbA1c level was 9.0%, with a required daily insulin dose of 75 units. She underwent laparoscopic sleeve gastrectomy. At 1 year after surgery, her body weight had decreased to 81.0 kg and her body mass index to 32.2 kg/m2. In addition, her daily required dose of insulin had decreased to 24 units, with an improvement in her HbA1c level to 7.7%.ConclusionsAlthough further evidence needs to be accumulated, including long-term outcomes, laparoscopic sleeve gastrectomy may provide an effective treatment for patients with morbid obesity and T1DM for body weight loss, improvement in HbA1c level, and insulin dose reduction.

Conclusions: further evidence needs to be accumulated, including long-term outcomes, laparoscopic sleeve gastrectomy may provide an effective treatment for patients with morbid obesity and type 1 diabetes mellitus (T1DM) for body weight loss, improvement in HbA1c level, and insulin dose reduction
In Japan, only two studies have described the effect of Ichikawa et al surg case rep (2021) 7:7 bariatric surgery on slowly progressive insulin-dependent diabetes mellitus (SPIDDM), which is included in T1DM [10, 11], and no studies on bariatric surgery for patients with severe obesity and T1DM with insulin secretion deficiency
Summary
Further evidence needs to be accumulated, including long-term outcomes, laparoscopic sleeve gastrectomy may provide an effective treatment for patients with morbid obesity and T1DM for body weight loss, improvement in HbA1c level, and insulin dose reduction.
