What is LDL Cholesterol?
LDL plays an essential role by delivering cholesterol to cells throughout the body, where it is used for hormone production, cell membranes, and other important biological functions. However, when LDL levels remain elevated over time, excess cholesterol may accumulate within artery walls, increasing cardiovascular risk.
LDL levels are influenced by genetics, nutrition, physical activity, body weight, smoking, stress, medications, and overall metabolic health. Because these factors often change gradually, monitoring LDL trends provides significantly more value than relying on a single laboratory result.
Tracking LDL allows you to observe how changes in diet, exercise, weight management, and other healthy habits influence your cardiovascular health over time. Regular monitoring also helps establish your personal baseline and provides valuable information about your long-term wellness.
Rather than viewing LDL as simply "good" or "bad," understanding how it changes over time, alongside other lipid markers, offers a more complete picture of your cardiovascular health and the effectiveness of your lifestyle choices.

Fatty deposits around the eyes
