Diabulimia and Type 1 Diabetes: An Unknown and Emerging Problem

Area of Science:

• Endocrinology
• Psychiatry
• Nutritional Science

Background:

• Type 1 Diabetes Mellitus (T1DM) patients exhibit a higher prevalence of eating disorders, including diabulimia, impacting glycemic control and insulin management.
• Approximately 30-40% of young T1DM patients suffer from eating disorders, posing significant challenges to treatment adherence and metabolic outcomes.
• Hybrid closed-loop systems (HCLS) offer therapeutic flexibility, but accurate carbohydrate counting remains essential for effective insulin dosing.

Purpose of the Study:

• To present a case study of diabulimia in a T1DM patient and highlight the effectiveness of an integrated multidisciplinary approach.
• To emphasize the challenges in diagnosing eating disorders among T1DM patients and the need for standardized screening methods.

Main Methods:

• A case report detailing a 30-year-old female T1DM patient with poor glycemic control and a history of substance abuse and depression.
• Implementation of carbohydrate counting education and HCLS, followed by the identification of reduced prandial insulin boluses and fear of weight gain.
• A multidisciplinary intervention involving diabetologists, psychiatrists, and dietitians, including fortnightly evaluations, bioimpedance assessments, and a fixed carbohydrate diet.

Main Results:

• The patient initially showed improved glycemic control with HCLS and carbohydrate counting education.
• Progressive reduction and cessation of prandial insulin boluses and development of weight gain fears indicated potential diabulimia.
• The integrated approach led to better glycometabolic control and increased patient understanding of their condition.

Conclusions:

• Diagnosing eating disorders in T1DM patients is challenging due to the critical importance of food intake and insulin adjustments.
• There is a lack of standardized screening tools for eating disorders in the T1DM population.
• An integrated, multidisciplinary approach is fundamental for addressing diabulimia and similar emerging issues in T1DM management.
