Lowering cholesterol levels can vary depending on individual circumstances and the approach taken. Making lifestyle changes, such as adopting a healthy diet and increasing physical activity, can often lead to noticeable improvements in cholesterol levels within a few weeks to a few months. Additionally, if cholesterol-lowering medication is prescribed, it may take several weeks to months to see significant changes in cholesterol levels. It’s important to work closely with a healthcare provider to create a personalized plan for managing cholesterol and to monitor progress over time.
