Treatment of the disease of obesity in patients with type 1 diabetes with tirzepatide: a protocol for a randomised controlled trial in a single-centre setting

Introduction Medication for the disease of obesity has improved, and clinical trials based on natural gut hormones such as tirzepatide, showed only mild side effects and ~22% weight loss maintenance. However, patients with type 2 diabetes only lose 15% bodyweight with tirzepatide while tolerating the medications very well, but little is known in patients with the disease of obesity who also have type 1 diabetes, especially regarding safety of the medications.

Tirzepatide's licence in the Gulf countries and Europe for obesity does not exclude patients with obesity and type 1 diabetes, unlike the USA. In Kuwait, more than a quarter of patients with type 1 diabetes also have the disease of obesity.

Tirzepatide is not approved for glycaemic control in patients with type 1 diabetes, because it is unlikely to make a difference. Because tirzepatide is approved for the treatment of obesity in patients who also have type 1 diabetes we can now test how effective treatments for obesity such as tirzepatide are for patients with obesity and type 1 diabetes.
