Some studies suggest type 2 diabetes progresses faster in children and young people, while other studies indicate that both types lead to similar perinatal outcomes and increased risk of coagulatory disorders.

Diabetes mellitus is a chronic condition characterized by elevated blood glucose levels due to issues with insulin production or function. There are two primary types: Type 1 diabetes (T1D) and Type 2 diabetes (T2D). Understanding which type is more severe involves examining various factors such as disease progression, complications, and outcomes.
Research indicates that Type 2 diabetes progresses more rapidly in children and young people compared to Type 1 diabetes in the same age group. Specifically, beta-cell function deteriorates at a rate of 20% to 35% annually in youth with T2D, compared to 7% to 11% in adults with T2D. This rapid progression leads to faster treatment failure and a higher risk of complications such as nephropathy, neuropathy, and cardiovascular diseases in youth with T2D compared to those with T1D.
Metabolomic studies have shown that both T1D and T2D are associated with significant alterations in plasma metabolites, including glucose, fructose, amino acids, and lipids. These changes are predictive of disease progression and complications in both types of diabetes. However, the specific metabolic pathways affected can differ, influencing the overall disease severity and management strategies.
Both T1D and T2D significantly increase the risk of cardiovascular diseases due to physiological changes affecting haemostasis. These changes include altered concentrations of coagulatory proteins, hyper-activation of platelets, and endothelial dysfunction. However, the mechanisms and extent of these changes can vary between the two types, potentially influencing the severity of cardiovascular complications.
In pregnant women, T2D is associated with a higher risk of perinatal mortality compared to T1D, despite generally milder glycemic disturbances. This suggests that T2D can have more severe implications during pregnancy, affecting both maternal and fetal outcomes.
Both T1D and T2D require lifelong management, often involving insulin therapy and oral hypoglycemic agents. However, these treatments can lead to side effects and treatment failure, particularly in T2D due to its rapid progression in youth . Emerging treatments, such as gene therapy and beta-cell regeneration, offer potential future interventions but are not yet widely available.
While both Type 1 and Type 2 diabetes are serious conditions with significant health implications, Type 2 diabetes, particularly when it begins in youth, tends to progress more rapidly and leads to more severe complications compared to Type 1 diabetes. This rapid progression and higher risk of complications make T2D a particularly challenging condition to manage, highlighting the need for new and effective treatments.
