[Childhood obesity as a risk factor for diabetes mellitus type I: the accelerator hypothesis]

Area of Science:

• Pediatrics
• Endocrinology
• Metabolic Disorders

Background:

• Childhood obesity is a growing concern globally.
• Type I diabetes mellitus (DM) is typically diagnosed in childhood.
• The relationship between overweight/obesity and type I DM risk is under investigation.

Observation:

• Two children, a 10.9-year-old girl and a 10.3-year-old boy, were diagnosed with type I DM.
• Both children presented with overweight/obesity.
• Treatment involved subcutaneous insulin injections and dietary modifications.

Findings:

• The accelerator hypothesis suggests a common pathway for type I and type II DM.
• This hypothesis involves genetic predisposition, insulin resistance from rapid weight gain, and autoimmunity.
• These factors can lead to beta-cell insufficiency.

Implications:

• Clinicians should consider type I DM in overweight or obese children.
• Symptoms like polydipsia and polyuria in obese children warrant prompt diagnostic evaluation for DM.
• Early diagnosis and management are crucial for preventing long-term complications.
