Diagnostic Considerations
Children with MODY may present as having type 1 diabetes. As they may respond better to oral hypoglycemic agents, recognizing MODY as a possibility is important. Always consider the diagnosis of MODY in the following circumstances:
- A strong family history of diabetes across 2 or more generations - The age of diagnosis usually falls with each successive generation
- Persistently low insulin requirements, particularly with good blood glucose control
- Development of diabetes from birth or within the first 9 months of life
Conditions to consider in the differential diagnosis of type 1 diabetes include the following:
- Type 2 diabetes mellitus
- MODY
- Psychogenic polydipsia
- Nephrogenic diabetes insipidus
- High-output renal failure
- Transient hyperglycemia with illness and other stress
- Steroid therapy
- Factitious illness (Münchhausen syndrome by proxy)
