What Causes Cholesterol?
July 15, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's
Cholesterol is a waxy, fat-like substance that is produced naturally by the liver and is also present in certain foods. It plays essential roles in the body, including building cell membranes, producing hormones, and aiding in digestion. Cholesterol is transported in the bloodstream in the form of lipoproteins. However, an imbalance in the levels of cholesterol and lipoproteins can lead to health problems. Here are the main factors that can contribute to high cholesterol levels:
- Diet: Consuming foods that are high in saturated and trans fats can increase cholesterol levels. These fats are commonly found in fatty meats, full-fat dairy products, processed foods, fried foods, and baked goods. Additionally, foods high in cholesterol, such as organ meats and shellfish, can also contribute to elevated cholesterol levels in some individuals.
- Obesity: Being overweight or obese can impact cholesterol levels. Excess body weight, particularly abdominal fat, can increase LDL cholesterol (often referred to as “bad” cholesterol) and lower HDL cholesterol (“good” cholesterol) levels.
- Lack of physical activity: A sedentary lifestyle can lead to higher cholesterol levels. Regular physical activity helps raise HDL cholesterol and promotes overall cardiovascular health.
- Genetics and family history: Genetic factors can affect how the body produces, processes, and removes cholesterol. Some individuals have a genetic predisposition to high cholesterol levels, known as familial hypercholesterolemia. Having a family history of high cholesterol or cardiovascular disease can also increase the risk of elevated cholesterol levels.
- Age and gender: Cholesterol levels tend to rise with age, especially in men. Before menopause, women generally have lower total cholesterol levels than men. However, after menopause, women’s LDL cholesterol levels often increase.
- Certain medical conditions: Certain medical conditions and diseases can contribute to high cholesterol levels. For example, conditions such as diabetes, hypothyroidism, chronic kidney disease, and liver diseases can affect cholesterol metabolism.
It’s important to note that while diet and lifestyle factors play a significant role in cholesterol levels, some individuals may have high cholesterol due to genetic factors or underlying health conditions. Regular cholesterol screenings and discussions with healthcare professionals are important to monitor and manage cholesterol levels effectively. Lifestyle modifications, such as adopting a heart-healthy diet, engaging in regular exercise, and, in some cases, medication, may be recommended to manage cholesterol levels and reduce the risk of cardiovascular disease.
