Read the case study listed below. Refer to the rubric for grading requirements. Utilizing the Week 6 Case Study Template, provide your responses to the case study questions below. You must use at least one scholarly reference to support pathophysiology statements, which can include the textbook. Use the current Clinical Practice Guideline (CPG) for the Standards of Medical Care in Diabetes—Abridged for Primary Care Providers from the American Diabetes Association to determine the patient's type of diabetes and inform treatment recommendations. Proper APA formatting (in-text citations, references, spelling, grammar, and English language) is required.

The case concerns J.T., a 48-year-old male presenting with symptoms such as fatigue, weight loss, extreme thirst, and increased appetite. His medical history includes hypertension, hyperlipidemia, and obesity. Laboratory findings reveal elevated fasting glucose and an oral glucose tolerance test (OGTT) result of 220 mg/dL, with an A1C of 7.2%. These findings are indicative of diabetes mellitus. Based on the clinical presentation and lab results, the most likely diagnosis is Type 2 Diabetes Mellitus (T2DM), a condition characterized by insulin resistance and relative insulin deficiency.

The pathophysiology of T2DM involves a complex interplay between insulin resistance in peripheral tissues—primarily muscle, adipose, and liver—and a progressive decline in pancreatic beta-cell function (American Diabetes Association, 2023). Initially, the body's cells become less responsive to insulin, prompting the pancreas to produce more insulin to maintain normal glucose levels. Over time, the beta cells fail to compensate adequately, leading to hyperglycemia. This combination of insulin resistance and beta-cell dysfunction results in the hallmark elevated blood glucose levels seen in T2DM. Chronic hyperglycemia damages blood vessels and nerves, leading to complications such as cardiovascular disease, nephropathy, neuropathy, and retinopathy.

Supporting subjective findings include: (1) increased fatigue, which reflects disrupted glucose metabolism and impaired energy production; (2) excessive thirst and frequent urination (nocturia), indicative of osmotic diuresis caused by hyperglycemia; and (3) weight loss, a common feature due to catabolic states triggered by insulin deficiency. Objective findings supporting the diagnosis are: (1) fasting plasma glucose of 136 mg/dL, which qualifies for diabetes; (2) elevated A1C of 7.2%, confirming chronic hyperglycemia; and (3) positive OGTT result of 220 mg/dL, demonstrating impaired glucose tolerance consistent with diabetes (American Diabetes Association, 2023).

Management of the Disease

In accordance with the ADA's Standards of Medical Care in Diabetes, initial pharmacological treatment typically involves metformin, an evidence-based first-line medication that enhances insulin sensitivity. Two "Evidence A" medication classes recommended by the ADA are:

  • Biguanides (e.g., Metformin): Metformin decreases hepatic glucose production and improves peripheral insulin sensitivity (American Diabetes Association, 2023).
  • SGLT2 inhibitors (e.g., Empagliflozin): These medications block glucose reabsorption in the kidneys, promoting glucosuria and lowering plasma glucose levels (Zinman et al., 2015).

The mechanism of action for metformin involves activation of AMP-activated protein kinase (AMPK), which inhibits hepatic gluconeogenesis and enhances insulin-mediated peripheral glucose uptake. SGLT2 inhibitors, on the other hand, inhibit sodium-glucose co-transporter 2 in the proximal renal tubules, resulting in increased urinary glucose excretion, thereby reducing blood glucose (American Diabetes Association, 2023; Zinman et al., 2015).

Non-pharmacological management is equally vital. Recommended options include:

  • Dietary modifications emphasizing a balanced, calorie-controlled diet rich in fiber and low in refined sugars.
  • Regular physical activity, specifically moderate-intensity aerobic exercise such as brisk walking for at least 150 minutes per week, which improves insulin sensitivity and aids weight management (Colberg et al., 2016).

The ADA recommends personalized lifestyle interventions alongside pharmacotherapy for optimal glycemic control. Education on self-monitoring of blood glucose, weight management, and management of comorbidities like hypertension and dyslipidemia are integral components of comprehensive care.
