Summary
Type 2 diabetes is a condition where the body does not use insulin properly and does not produce enough insulin to keep blood sugar levels normal. In children, obesity is the most common cause of type 2 diabetes.
Many children with type 2 diabetes do not show symptoms and are diagnosed during routine check-ups, especially if they have risk factors like a family history of diabetes, obesity, or dark patches of skin (acanthosis nigricans).
The good news is that type 2 diabetes can often be prevented or delayed with healthy lifestyle changes, such as maintaining a healthy weight and being physically active.
Diagnosis and When to Seek Help
A doctor may check for type 2 diabetes if your child:
- Is overweight or obese
- Has a family history of diabetes
- Develops dark, velvety skin patches (acanthosis nigricans)
- Has symptoms like frequent urination, increased thirst, or unexplained tiredness
A diagnosis is confirmed through blood tests that measure blood sugar levels. In some cases, diabetes is discovered during routine screenings for school, sports, or annual check-ups.
Management
The main goals of treatment are to:
- Help children reach and maintain a healthy weight
- Improve their ability to exercise
- Reduce acanthosis nigricans
- Keep blood sugar levels within a healthy range (HbA1c target: below 7%)
- Prevent long-term complications like vision problems, high blood pressure, and high cholesterol
Treatment usually starts with lifestyle changes, including a balanced diet and regular exercise. In some cases, medications like metformin or insulin may be needed. Some newer medications, such as GLP-1 receptor agonists and SGLT2 inhibitors, are approved for children aged 10 and older in some countries.
Follow-Up and Monitoring
Children with type 2 diabetes need regular doctor visits to check their blood sugar levels, monitor their growth, and adjust their treatment if needed. Long-term care focuses on preventing complications and maintaining a healthy lifestyle.
Early diagnosis and treatment can help children manage diabetes effectively and lead a healthy, active life. If you have concerns about your child’s risk for diabetes, talk to a healthcare provider.
