ICD-10 Code: E11
DESCRIPTION
Type 2 diabetes develops when insulin secretion cannot meet the increased demand posed by insulin resistance. Type 2 diabetes may be associated with hyperlipidemia, hypertension, acanthosis nigricans, ovarian hyperandrogenism and non-alcoholic fatty liver disease (features of insulin resistance).
DIAGNOSTIC CRITERIA
Clinical
- Obesity or overweight.
- Children with a strong family history of type 2 diabetes, usually in adolescents with BMI > 95th centile without auto-antibodies to islet cells and normal serum C-peptide levels.
- Keto-acidosis is unusual in type 2 diabetes.
- A fasting glucose > 7.0 mmol/L.
- Type 2 diabetics may have minimal symptoms or signs for months or even years before the diagnosis.
Investigations
To confirm diagnosis:
- Symptoms of diabetes.
PLUS
- Fasting plasma glucose > 7.0 mmol/L.
OR
- Random plasma glucose 11.0 mmol/L.
OR
- No symptoms, but an abnormal 2-hour serum glucose level on the oral glucose tolerance test:
- Ingestion of 1.75 g/kg (maximum 75 g) of glucose dissolved in water.
- Serum glucose > 11.0 mmol/L 2 hours post ingestion of oral glucose.
GENERAL AND SUPPORTIVE MEASURES
- Lifestyle modification:
Manage patients who are not ill at diagnosis initially with advice on nutrition and exercise, but most will eventually require medicine therapy. - Education on routine blood glucose monitoring. A logbook with all blood glucose readings should be kept. In most cases fasting, pre-breakfast measurement and 2-hour postprandial dinner measurement are sufficient.
- Initial medicine treatment is determined by symptoms, severity of hyperglycaemia and presence of ketosis. This should be decided in consultation with a specialist who is experienced in treating these children.
MEDICINE TREATMENT
