Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly
utilized as a primary treatment option for patients with type 2 diabetes
(T2D) due to their efficacy in glycemic control, weight management, and
cardiovascular protection. However, a notable proportion of patients may
require treatment intensification to achieve optimal glycemic targets. This
article reviews the strategies for treatment intensification following the use
of GLP-1 RAs, including the addition of other pharmacologic agents and
lifestyle interventions. A thorough examination of current research reveals
the importance of tailoring treatment plans to address the individual needs
of patients, thereby improving overall outcomes.

Type 2 diabetes (T2D) poses a significant global health challenge, characterized by insulin resistance and subsequent beta-cell dysfunction. The prevalence of T2D continues to rise, necessitating effective management strategies. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have garnered attention for their dual role in enhancing glycemic control while promoting weight loss. However, the need for treatment intensification remains common as not all patients achieve target glycemic levels with monotherapy. In this article, we explore the rationale and methods for intensifying treatment following GLP-1 RA initiation, synthesizing available evidence to inform clinical practice [1,2].
Overview of type 2 diabetes
Type 2 diabetes (T2D) is a chronic metabolic disorder characterized by insulin resistance and impaired insulin secretion, leading to elevated blood glucose levels. Its prevalence has surged globally, being a significant public health concern with implications for both morbidity and mortality. T2D is associated with various complications, including cardiovascular disease, neuropathy, retinopathy, and kidney failure. Risk factors include obesity, sedentary lifestyle, genetic predisposition, and age. Early diagnosis and effective management are critical to prevent long-term complications and to improve the quality of life for individuals with the condition [3,4].
Role of glucagon-like peptide-1 receptor agonists
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as a vital therapeutic option in the management of T2D. These agents act by enhancing glucose-dependent insulin secretion, suppressing glucagon release, slowing gastric emptying, and promoting satiety, which collectively contribute to improved glycemic control. Additionally, GLP-1 RAs have shown favourable effects on weight management and cardiovascular health, making them particularly beneficial for overweight patients with T2D. Despite their efficacy, many patients may still struggle to achieve optimal glycemic targets, necessitating an exploration of treatment intensification strategies following the initiation of GLP-1 RA therapy [5,6].
GLP-1 RAs mimic the actions of the endogenous hormone GLP-1, promoting insulin secretion, inhibiting glucagon release, and delaying gastric emptying. While these therapies effectively lower HbA1c levels and support weight loss, it is essential to recognize that approximately 30-40% of patients may not reach their glycemic goals solely through GLP-1 RA therapy [7]. This necessitates a comprehensive approach to treatment intensification that could include:
Clinical studies have demonstrated that treatment intensification with combination therapy, particularly with metformin or SGLT2 inhibitors, can significantly enhance glycemic control in patients using GLP-1 RAs. For instance, research has shown that the combination of a GLP-1 RA with metformin can reduce HbA1c levels by up to 1.5% more than either agent alone. Additionally, the addition of SGLT2 inhibitors not only aids in glycemic control but also offers cardiovascular benefits, especially for patients with comorbid conditions [9].
The decision to intensify treatment post-GLP-1 RA initiation must be individualized, taking into account several factors including baseline HbA1c levels, patient preferences, comorbid conditions, and potential side effects of new medications. The most effective treatment strategies often involve multidisciplinary care, integrating endocrinologists, dietitians, and diabetes educators. Moreover, patient adherence plays a significant role in the success of treatment intensification. Educating patients about the importance of their diabetes management plan can enhance adherence and, consequently, clinical outcomes. The healthcare team must also be vigilant for adverse effects, particularly gastrointestinal issues associated with GLP-1 RAs and hypoglycemia risks when adding insulin [10].
Treatment intensification following glucagon-like peptide-1 receptor agonist therapy is a critical consideration for achieving personalized and effective management of type 2 diabetes. By leveraging combination therapy, promoting lifestyle changes, and emphasizing patient engagement, healthcare providers can better meet the diverse needs of individuals with T2D. Continued research is essential to further refine treatment protocols and optimize outcomes for this growing patient population. As we advance our understanding and application of diabetes therapies, a holistic approach that centers on each patient's unique circumstances will prove crucial in the management of type 2 diabetes.
