Why Cholesterol Can Remain High Despite a Healthy Diet

High cholesterol can affect people who otherwise appear to be in good health, including those with normal blood pressure, healthy blood sugar levels and a suitable weight. Regular physical activity and a balanced diet do not rule it out.

Diet is only one influence on cholesterol levels. The body also produces cholesterol, and inherited factors can affect how effectively it clears cholesterol from the blood. As a result, some people may have elevated levels despite healthy habits.

Other factors that can contribute include age, certain medical conditions and some medications. A medical assessment can help identify why cholesterol is high rather than assuming that food choices alone are responsible.

High cholesterol usually causes no noticeable symptoms. A blood test is needed to measure it, so feeling well or maintaining a healthy weight does not necessarily provide reassurance about cholesterol levels.

Healthy eating and exercise remain important, but they may not be enough for everyone. People with elevated cholesterol should discuss their results, family history and overall cardiovascular risk with a healthcare professional to determine whether further evaluation or treatment is needed.
