From the Guidelines
A triglyceride level of 446 mg/dL in a 60-year-old diabetic patient with an A1c of 9.6% while on metformin 1000 mg requires immediate attention, and I recommend increasing diabetes management with additional medications and starting a lipid-lowering agent. The patient's current metformin regimen should be optimized to 1000 mg twice daily if tolerated, as metformin is the first-line agent for older adults with type 2 diabetes and can be used safely in patients with estimated glomerular filtration rate ≥30 mL/min/1.73 m² 1. Considering the patient's A1C level is ≥1.5% above the individualized glycemic goal, dual-combination therapy or a more potent glucose-lowering agent should be considered to achieve and maintain the goal A1C level 1. Adding a second diabetes medication like a GLP-1 receptor agonist (such as semaglutide) or an SGLT-2 inhibitor can be beneficial, especially since the patient is at high risk for cardiovascular disease and has poorly controlled diabetes 1. Dietary changes, including limiting simple carbohydrates, sugary beverages, and alcohol, while increasing fiber intake and following a Mediterranean-style diet, are crucial 1. Regular exercise of at least 150 minutes per week of moderate activity should be incorporated to improve glycemic control and reduce the risk of cardiovascular disease 1. Starting a lipid-lowering agent such as fenofibrate 145 mg daily or gemfibrozil 600 mg twice daily can help manage the patient's elevated triglyceride levels and reduce the risk of pancreatitis 1. These interventions are necessary to improve the patient's glycemic control, reduce the risk of cardiovascular disease, and enhance their overall quality of life. Key considerations include:
- Optimizing metformin regimen to 1000 mg twice daily if tolerated
- Adding a second diabetes medication like a GLP-1 receptor agonist or an SGLT-2 inhibitor
- Starting a lipid-lowering agent such as fenofibrate or gemfibrozil
- Implementing dietary changes and regular exercise to improve glycemic control and reduce cardiovascular risk.

From the Research
Triglyceride Management
- A 60-year-old diabetic patient with an A1c of 9.6 and triglycerides of 446 on 1000 metformin requires careful management of hypertriglyceridemia to reduce the risk of cardiovascular disease and pancreatitis 2, 3.
- The patient's high triglyceride level and diabetes status indicate a need for aggressive management, including lifestyle modifications and potentially pharmacological interventions 2, 4.
Lifestyle Modifications
- Dietary changes, such as lowering carbohydrate intake and increasing fat and protein intake, can help lower triglyceride levels 2.
- Moderate- to high-intensity physical activity can also lower triglyceride levels and improve body composition and exercise capacity 2.
Pharmacological Interventions
- Fenofibrate treatment has been shown to be effective in reducing triglyceride levels and improving glycemic control in diabetic patients with hypertriglyceridemia 5, 6.
- Statins can be considered for patients with high triglyceride levels who have borderline or intermediate risk of atherosclerotic cardiovascular disease 2, 4.
- Icosapent ethyl esters (a purified EPA) may be used for further ASCVD risk reduction in patients with residual mild to moderate hypertriglyceridemia on maximally tolerated statin and elevated cardiovascular risk 4.
Treatment Goals
- The primary goal of treatment is to reduce triglyceride levels and achieve optimal glycemic control to minimize the risk of cardiovascular disease and pancreatitis 2, 3.
- Secondary goals include reducing LDL cholesterol and non-HDL cholesterol levels, as well as improving insulin resistance and reducing inflammation 5, 6.
