Lifestyle Intervention for the Management of Hypercholesterolemia in a Low-Risk Middle-Aged Female: A Case Report

Background : Intensive lifestyle modification is central to dyslipidemia management, although pharmacologic therapy is often prioritized when lipid levels are moderately elevated. Similar to quality improvement efforts addressing pre-analytical variables in laboratory medicine—where outcomes depend on structured interventions and patient adherence—the management of hypercholesterolemia likewise requires sustained engagement in non-intuitive but beneficial health behaviors. Case Presentation : A 53-year-old woman with a 2–3-year history of hypercholesterolemia presented with total cholesterol 6.4 mmol/L (247.5 mg/dL), LDL-C 4.0 mmol/L (154.7 mg/dL), HDL-C 1.65 mmol/L (63.8 mg/dL), triglycerides 1.12 mmol/L (99.2 mg/dL), BMI 26.6 kg/m 2 , and blood pressure 95/60 mmHg. She had a family history of diabetes (grandmother), no smoking history, and no premature atherosclerotic cardiovascular disease. Statin therapy was initially recommended. Instead, she implemented a fat-restricted diet emphasizing fruits, vegetables, fish, chicken, and oatmeal, along with 1 hour of exercise 6 days per week. After 2 months, total cholesterol decreased to 5.3 mmol/L (205.0 mg/dL), LDL-C to 3.2 mmol/L (123.7 mg/dL), HDL-C remained stable at 1.63 mmol/L (63.0 mg/dL), triglycerides 0.81 mmol/L (71.69 mg/dL), BMI decreased to 24.7 kg/m 2 , and blood pressure remained stable. Carotid ultrasound showed normal morphology, vessel wall thickness, lumen diameter, and Doppler flow. Statin therapy was no longer recommended. Conclusion : Intensive lifestyle interventions are associated with significant improvements in lipid profiles among carefully selected low-risk patients and may reduce or obviate the need for pharmacologic therapy. Behavioral factors remain integral to the management of dyslipidemia, highlighting the importance of patient-driven modification of cardiovascular risk. Further large-scale, methodologically rigorous studies are warranted to validate the reproducibility and generalizability of these findings.
