Your symptoms of abnormal lipids and fatigue during exertion, like climbing stairs, require prompt medical evaluation to check your heart health. A doctor may recommend cholesterol-lowering medications, such as statins (like atorvastatin), to manage your lipid profile. Additionally, they might suggest diagnostic tests, such as an electrocardiogram (ECG) or a stress test, to ensure your heart is receiving adequate blood flow during physical activity. Lifestyle changes like a heart-healthy diet and guided exercise are also essential. Please consult your physician soon for a proper assessment to keep your heart safe and healthy.
