Until recently, type 2 diabetes was considered a lifestyle disease of mature people and less serious than type 1 diabetes. Young adult-onset type 2 diabetes has been revealed to be an aggressive condition with a high risk of diabetes complications and premature death, a risk greater than for those with type 1 diabetes.
- Early detection of diabetes in young people is extremely important. Practitioners should have a high index of suspicion and consider targeted testing in young adults with high-risk features.
- Obesity is the most prevalent modifiable risk factor and a strong family history or a history of in utero exposure to hyperglycaemia is associated with a younger onset of type 2 diabetes.
- Patients with young adult-onset type 2 diabetes have a high risk and prevalence of diabetic complications, often present at diagnosis.
- Given a high lifetime risk of complications, tight glycaemic control early in the diabetes disease process is likely to yield the greatest benefit for prevention.
- Monotherapy failure rate is higher than in older patients with type 2 diabetes.
- Mortality is driven by premature macrovascular disease, so cardiovascular disease risk factors should be attended to early.
- Clinicians should be aware that medication adherence is demonstrably low and psychosocial issues are frequent in this patient group and many are lost to follow up.
- Young adult-onset type 2 diabetes should be recognised as an aggressive disease requiring early intervention and multidisciplinary support, irrespective of the need for insulin therapy.
