Weight Loss Versus Glycemic Control as the Primary Treatment Target in Newly Diagnosed Type 2 Diabetes: Why Choose When You Can Have Both?

Abstract

Weight loss has been associated with significant improvements in glycemic control, quality of life, and comorbidities in people with type 2 diabetes. Furthermore, achieving diabetes remission can reduce the risk of microvascular complications and mitigate the burden of diabetes on healthcare systems. However, preventing weight regain is challenging in the long term. Strict glycemic control, particularly in the early stages of the disease, can reduce the subsequent risk of microvascular complications and specific macrovascular endpoints in the long run; however, its impact on cardiovascular and all-cause mortality remains controversial. New classes of antidiabetic agents, namely glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, have been shown to reduce cardiorenal risk and induce weight loss, in addition to effectively lowering blood glucose with a minimal risk of hypoglycemia. Recently, it has been debated whether weight loss or glycemic control should be the first priority in people with a recent diagnosis of type 2 diabetes. This article aims to discuss the debate from a clinical perspective, evaluate the advantages and disadvantages of each therapeutic strategy, and assess the impact of both approaches on the future risk of diabetic complications, based on the latest evidence. Given that both goals are equally important, the authors suggest that merging the two strategies, with the early and aggressive use of combination therapies consisting of glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, will confer maximum benefits in terms of weight loss and glycemic control, and will reduce the future risk of complications from diabetes. A personalized approach that takes into account specific patient characteristics, including age, sex, race, frailty, and cognitive status, among others, can lead to more effective diabetes care.
