Obesity is one of the main risk factors for type 2 diabetes (T2D), representing a major worldwide health crisis. Modest weight-loss (≥ 5% but < 10%) can minimize and reduce diabetes-associated complications, and significant weight-loss can potentially resolve disease. Treatment guidelines recommend that intensive lifestyle interventions, pharmacologic therapy, and/or metabolic surgery be considered as options for patients with T2D and obesity. The benefits and risks of such interventions should be evaluated in the context of their weight-loss potential, ability to sustain weight change, side effect profile, and costs. Antihyperglycemia therapies have considerable effects on patient weight, prompting careful consideration of weight-loss or weight-neutral therapies for patients with T2D who also have obesity. Metformin, sodium glucose co-transporter 2 inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1 RAs), α-glucosidase inhibitors, and amylin mimetics promote weight-loss. Dipeptidyl peptidase-4 inhibitors and fixed-ratio insulin/GLP-1 RA combination therapies (IDegLira, iGlarLixi) appear to be weight-neutral. Thiazolidinediones, insulin secretagogues (sulfonylureas, meglitinides), and insulins are associated with weight gain. Sulfonylureas are additionally associated with a higher risk of serious hypoglycemia from hyperinsulinemia, making them less suitable for the treatment of patients who are overweight or have obesity. Patients are often overtitrated on basal insulin, resulting in an increased risk of hypoglycemia and weight gain without achieving glycemic goals. Given these observations, the effects of antihyperglycemia agents on weight should be considered when individualizing T2D therapy.Funding: Sanofi US, Inc.

The current epidemic of type 2 diabetes (T2D) represents a significant global and national health concern. Globally, the prevalence of diabetes has doubled between 1980 and 2014. In 2014 the World Health Organization estimated that there were 422 million adults living with diabetes worldwide. In the USA, the number of people diagnosed with T2D is estimated to increase to over 70 million by 2050, putting an immense strain on the US healthcare system. Achieving glycemic control is widely acknowledged as the key goal of treatment in T2D and is critical for reducing the onset and progression of diabetes-related complications such as cardiovascular diseases, neuropathies, retinopathies, and nephropathies. Despite the increase in the availability of antihyperglycemic medications and evidence-based treatment guidelines, the proportion of people with T2D who fail to achieve glycemic goals continues to rise. One major contributor is a delay in treatment intensification despite suboptimal glycemic control, referred to as clinical or therapeutic inertia. Clinical inertia prolongs the duration of patients’ hyperglycemia which subsequently puts them at increased risk of diabetes-associated complications and reduced life expectancy. Clinical inertia results from a complex interaction between patient, healthcare providers, and healthcare system barriers that need to be addressed together, rather than as separate entities. In this article we provide an overview of clinical inertia in the clinical management of T2D and provide suggestions for overcoming aspects that may have a negative impact on patient care.Funding: Sanofi US, Inc.
