Summary
Binge eating disorder (BED) affects 9.5% of obese patients with type 2 diabetes (T2D) in Denmark, a higher prevalence than in the general population. This suggests BED screening may benefit T2D patients.
Area of Science:
- Endocrinology
- Psychiatry
- Public Health
Background:
- Binge eating disorder (BED) is a recognized diagnosis in Denmark.
- The general population prevalence of BED in Denmark is 2-3%.
- BED prevalence in Danish type 2 diabetes (T2D) patients is unknown.
Purpose of the Study:
- To estimate the prevalence of BED in obese patients with T2D in Denmark.
- To explore clinical differences between T2D patients with and without BED.
Main Methods:
- A cohort of 84 obese T2D patients (BMI ≥ 30 kg/m²) was recruited.
- Patients were screened for BED using the Binge Eating Disorder Questionnaire.
- Clinical data were collected and analyzed using statistical comparisons.
Main Results:
- 9.5% of obese T2D patients showed indication of BED.
- An additional 8.3% exhibited subthreshold BED symptoms.
- Patients with BED were younger, had earlier diabetes onset, and higher BMI.
Conclusions:
- Obese T2D patients exhibit a higher prevalence of BED than the general population.
- Systematic BED screening may be beneficial for obese T2D patients.
- Further research is required to understand the BED-T2D association fully.

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

2.1K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
