How Long It Takes to Lower Cholesterol, According to a Cardiologist
Heart disease remains the leading cause of death in the United States, and high cholesterol is one of its biggest risk factors. While our bodies needs cholesterol to build healthy cells and produce hormones, high levels of it can increase a person's risk. Over time, excess cholesterol can contribute to plaque buildup in the arteries, causing them to become narrowed or clogged, restricting blood flow. High cholesterol remains a major health concern in the United States, affecting roughly 71 million Americans. Fortunately if you're at risk, measures can be taken to manage it.
"If you want to manage or prevent high cholesterol, it's important to focus on a diet that reduces saturated and trans fats," says Nadim Geloo, MD, cardiologist and senior director of medical affairs for Abbott's structural heart division. "These are the primary contributors to elevated low-density lipoproteins, or 'bad' cholesterol levels."
Saturated fats are typically found in red meat, full-fat dairy products like butter, whole milk, and cheese, and certain oils, like palm oil. Trans fats are frequently found in processed foods such as packaged cookies, crackers, cakes, and fried foods. Geloo suggests checking ingredient labels for "partially hydrogenated oils," which is just a sneaky name for trans fats.
In addition to limiting these fats, eating foods rich in omega-3 fatty acids can support heart health. Fatty fish like salmon, mackerel, and herring are excellent sources of omega-3 fatty acids, along with plant-based options like flaxseeds, chia seeds, and walnuts. These foods may help lower triglyceride levels and support overall cardiovascular health.

When it comes to lowering high cholesterol, success comes from making consistent, long-term changes to both diet and lifestyle. Along with a balanced diet, that includes regular physical activity, maintaining a healthy weight, and avoiding smoking.
For individuals who do make an effort to improve lifestyle habits, Geloo says positive changes in cholesterol levels can often be seen within three to six months. However, that timeline may vary depending on factors such as the severity of the condition, consistency of lifestyle changes, genetic factors, and whether medications are part of the treatment plan.
"Inconsistency in lifestyle changes and relying on medication alone without lifestyle changes to support it may cause people to struggle with lowering their cholesterol," Geloo says. "It's crucial to remember that lowering and maintaining healthy cholesterol in the long-term means taking a holistic approach to wellness."
To check your cholesterol levels, schedule a lipid panel with your healthcare provider. It's important to consult with your doctor or a registered dietitian for personalized advice tailored to your specific health needs and circumstances. They can provide guidance based on your full health profile and determine an individualized treatment plan.
