This case study examines a 63-year-old Cuban male who presents seeking weight loss advice while exhibiting classical signs of Type 2 Diabetes Mellitus (T2DM) and hyperlipidemia. The paper reviews subjective and objective clinical findings, interprets laboratory results, and establishes primary and secondary diagnoses with supporting pathophysiology. It outlines a comprehensive care plan that includes diagnostic testing (HbA1c and fasting plasma glucose), pharmacological management (Metformin and Simvastatin), patient education on medications, diet, and exercise, and referrals to cardiology, ophthalmology, and dietetics. Comorbidities including arthritis are also assessed, and medication costs are evaluated to minimize financial burden on the patient.
The World Health Organization (WHO) defines diabetes as a disease that affects the body's ability to prepare or produce the hormone insulin, resulting in abnormal metabolism of blood glucose and elevated levels of the same in the blood (WHO, 2021). When an individual has diabetes, their body either does not make sufficient insulin or fails to use insulin as it should, causing elevated levels of blood sugar in the bloodstream. There are three types of diabetes: Type 1 diabetes, Type 2 diabetes, and gestational diabetes (CDC, 2020). The Centers for Disease Control and Prevention (CDC) estimates that 34 million Americans — representing 1 in every 10 — have diabetes, and 90–95 percent of these patients have Type 2 diabetes (CDC, 2020).
The high prevalence of diabetes calls for adequate understanding on the part of healthcare providers to ensure effective diagnosis and management. This case study reviews the subjective and objective information provided by a 63-year-old Cuban male client who presents for weight loss advice and shows some classical signs of diabetes. It interprets lab results, identifies primary and secondary diagnoses, analyzes the costs of identified medications, and provides pertinent patient education to enhance the client's quality of life.
Type 2 Diabetes Mellitus (T2DM) is caused by the inability of the body's tissues to respond appropriately to insulin — a condition known as insulin resistance (Galicia-Garcia, 2020). The pancreas produces more insulin in an attempt to elicit a response from the body, but this process eventually leads to elevated blood sugar levels that can cause serious medical conditions such as kidney disease, vision loss, and heart disease (Galicia-Garcia, 2020).
The client complains of worsening fatigue, excessive thirst and fluid intake (polydipsia), nocturia two to three times per night, poor vision (evident from the use of contact lenses), and worsening weight gain despite working out twice a week. The CDC identifies excessive urination, excessive thirst, worsening hunger, vision loss, and excessive fatigue as classical symptoms of T2DM (CDC, 2021). The lab finding of glucose in the urine (glycosuria), as shown in the urinalysis (glucose 1+), points to the presence of T2DM, as it implies that there is too much blood sugar for the body to reabsorb, causing some of it to pass into the urine (Storey et al., 2018).
The client's blood glucose levels are normal at 95 mg/dL. A person with T2DM will typically report blood glucose levels above 126 mg/dL, while someone with pre-diabetes will report glucose levels between 100 and 125 mg/dL (Huang et al., 2017). Further, the client reports negative ketones in the urine. T2DM patients are at higher risk of developing ketones due to insufficient insulin levels. The client does not report neuropathy or very dry skin, both of which are classical symptoms of T2DM (CDC, 2021). Family history is also not indicative of T2DM (ADA Standards of Medical Care, 2020).
The lab finding of glycosuria, coupled with the positive findings of visual abnormalities, polyuria, polydipsia, and worsening fatigue, points to the likelihood of T2DM. The ADA Standards of Medical Care further note that a T2DM diagnosis could be considered in obese individuals with high-risk race/ethnicity, hypertension, and cardiovascular disease (CVD) (ADA Standards of Medical Care, 2020). The client's BMI of 33.3 indicates obesity, further supporting this diagnosis.
Hyperlipidemia is a medical term used to describe abnormally high levels of lipids or fats in the blood (Hill & Bordoni, 2021). It most commonly results from unhealthy lifestyle choices — such as high-fat diets — that cause cholesterol to build up on the walls of blood vessels, increasing the risk of atherosclerosis (Hill & Bordoni, 2021).
Hyperlipidemia typically has no symptoms. However, several factors place this individual at high risk, including obesity and a family history of coronary artery disease (CAD), which results from cholesterol buildup within the coronary artery (Hill & Bordoni, 2021). The client's total cholesterol (TC), LDL, HDL, and triglycerides are all outside normal ranges. Healthy levels of total cholesterol are between 100 and 200 mg/dL (compared to the client's 230 mg/dL); LDL should be less than 100 mg/dL (compared to the client's 144 mg/dL); HDL should be 40 mg/dL or higher (compared to the client's 38 mg/dL); and triglycerides should be less than 150 mg/dL (compared to the client's 232 mg/dL) (Bibiloni et al., 2016).
The client has no history of tobacco use and reports engaging in frequent physical exercise. Smoking, lack of exercise, and high-fat diets are classical risk factors for hyperlipidemia (Bibiloni et al., 2016). Additionally, the client's sinus rhythm on the EKG and pulse rate are both normal, indicating a currently healthy cardiac function.
The patient presents with elevated cholesterol levels and HDL below the normal range. The elevated cholesterol, combined with weight gain and a family history of CAD, points to the likelihood of hyperlipidemia.
The A1C test indicates the average blood sugar level over the past two to three months. It measures the percentage of blood sugar attached to hemoglobin in the red blood cells (Bigelow & Freeland, 2017). High blood sugar levels generally translate to more hemoglobin with attached blood sugar. HbA1C levels of 5.7 percent or below are considered within normal range, while those above 6.5 percent are indicative of diabetes (Bigelow & Freeland, 2017).
The client exhibits several classical symptoms of diabetes, but their blood glucose levels are within normal range and there is no family history of diabetes. A baseline HbA1C test will help ascertain the presence of Type 2 diabetes and should be administered immediately, with a repeat test after three months (Bigelow & Freeland, 2017). The ADA Standards of Medical Care recommend a baseline HbA1C test for adults over 45 years of age who have obesity and one or more risk factors for diabetes or pre-diabetes — including high-risk ethnicity, high cholesterol, CAD history, physical inactivity, and hypertension (ADA Standards of Medical Care, 2021). If the test result is normal, the patient should be kept under observation and a repeat test conducted every three years, or earlier depending on risk status and initial results (ADA Standards of Medical Care, 2021).
The fasting plasma glucose (FPG) test measures a patient's blood glucose levels at a single point in time — preferably in the morning after fasting for at least eight hours (NIH, 2016). Fasting means consuming nothing except sips of water. Given the high cost of diabetes medication and treatment, it may be prudent to confirm the presence of diabetes through multiple diagnostic tests.
