Common Comorbidities and Complications of Prediabetes

Obesity 
Obesity is a neuroendocrine disease that is itself associated with numerous metabolic and biomechanical complications. It is generally defined as a body mass index (BMI) ≥30 kg/m2, especially in the presence of obesity-related complications. In the context of prediabetes, obesity (1-3):

Management of Prediabetes

Treatment Goals 
The primary goal of prediabetes management is to normalize glucose levels and prevent or delay progression to diabetes and associated microvascular complications (1,2). Management of common prediabetes comorbidities such as obesity, hypertension, dyslipidemia, cardiovascular disease, and chronic kidney disease is also essential.

The Burden of Diabetes

Epidemiology

Diabetes affects 9.4% of the population of the United States, or approximately 30.3 million people. Of these, 7.2 million have not been diagnosed. Approximately 90% of all diabetes cases are type 2 diabetes.1

Diagnosis of Type 2 Diabetes Mellitus

There is a continuum of risk for poor patient outcomes as glucose tolerance progresses from normal to overt type 2 diabetes.

Diabetes and Cancer

Epidemiologic data have demonstrated significant increases of various cancers in people with obesity and diabetes. Recently, concern has emerged that antihyperglycemic medications may also be associated with an increased prevalence of multiple cancers; however, available data are limited and conflicting.1,2

Team Approach to Type 2 Diabetes Management

Comprehensive care of patients with diabetes requires a team of healthcare professionals. Working with different healthcare providers allows the patient to learn in-depth information regarding their health and well-being. It also ensures that the patient’s needs are cared for and addressed.

Definition

Screening and Monitoring of Prediabetes

AACE recommends that individuals who meet any of the clinical risk criteria noted below should be screened for prediabetes or type 2 diabetes (T2D)1.

Type 1 Diabetes Pathophysiology

Type 1 diabetes (T1D) is a chronic autoimmune disorder that occurs in genetically susceptible individuals and that may be precipitated by environmental factors. In a susceptible individual, the immune system is triggered to develop an autoimmune response against altered pancreatic beta cell antigens, or molecules in beta cells that resemble a viral protein.

Type 2 Diabetes Glucose Management Goals

Optimal management of type 2 diabetes requires treatment of the “ABCs” of diabetes: A1C, blood pressure, and cholesterol (ie, dyslipidemia). This web page provides the rationale and targets for glucose management; AACE guidelines for blood pressure and lipid control are summarized in Management of Common Comorbidities of Diabetes.

Management of Common Co-morbidities of Diabetes

As may be expected with a chronic disease that primarily affects middle-aged and older individuals, type 2 diabetes is usually complicated by other medical conditions.
