What Is High Cholesterol and What Causes It?
Cholesterol is a fatty substance in the blood that is key to the body’s functioning. While cholesterol is necessary for building cells and hormones, having too much of it, known as high cholesterol, can become a concern. High cholesterol often has no obvious warning signs, which makes regular check-ups with a physician valuable in understanding and managing this condition. Understanding what contributes to high cholesterol levels is key to maintaining a healthy lifestyle. Below, we’ll explore high cholesterol, how it affects the body, and what factors contribute to its development.
What Is High Cholesterol?
Cholesterol is produced naturally by the liver and is also found in foods like meat, dairy, and processed items. The body needs it to function properly; however, excess cholesterol can build up in the arteries, leading to restricted blood flow. This is often referred to as high cholesterol. Over time, this restricted blood flow increases the risk of heart problems or stroke.
Cholesterol is typically classified into low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL, often called “bad cholesterol,” contributes to buildup in the arteries, while HDL, or “good cholesterol,” helps remove excess cholesterol from the bloodstream. A blood test conducted by a physician can evaluate cholesterol levels and determine whether adjustments are needed to maintain balance.
What Causes of High Cholesterol?
Understanding the root causes of high cholesterol makes identifying habits and conditions requiring attention easier. The foods consumed on a daily basis can have a significant impact on cholesterol levels. Diets high in saturated fats, trans fats, and cholesterol-rich foods are major contributors. Frequent consumption of fast food, processed snacks, and sugary desserts can raise LDL levels, negatively affecting cardiovascular health. On the other hand, adding more fruits, vegetables, whole grains, and lean proteins can help balance cholesterol levels. Replacing unhealthy fats with heart-healthy alternatives like olive oil or avocados may also support better outcomes.
What Lifestyle Changes Affect Cholesterol?
Sedentary behavior can play a role in raising harmful cholesterol levels while lowering good cholesterol. A lack of exercise often leads to weight gain and reduced metabolism, making it more challenging for the body to process fats and sugars effectively. Even moderate physical activity, such as brisk walking for 30 minutes daily, can improve cholesterol numbers and overall health.
Smoking damages blood vessels and can lower HDL, further increasing the risks associated with high cholesterol. Similarly, excessive alcohol consumption may lead to higher LDL levels and other complications such as weight gain or liver issues. Reducing smoking and moderating alcohol intake can assist in managing cholesterol levels in the long term.
What Other Factors Are There?
Family history plays a significant role in cholesterol levels. Certain inherited conditions, such as familial hypercholesterolemia, can lead to high cholesterol, even in individuals who maintain healthy habits. Consulting a physician and performing regular screenings may help individuals with a family history of high cholesterol manage their risks more effectively.
Age and underlying health conditions, such as obesity or diabetes, can also contribute. Cholesterol levels often rise with age as the body’s ability to process fats declines. Managing other health conditions like high blood pressure or diabetes in consultation with a physician can help lower the risk of elevated cholesterol levels.
Take Action With Your Physician
Recognizing high cholesterol early provides an opportunity to make meaningful changes before complications arise. Regular screenings, especially for individuals over 40 or with a family history of cholesterol issues, are strongly recommended. Working closely with healthcare professionals to develop a personalized approach, including diet, exercise, and medication if necessary, can make a significant difference.
