Cholesterol is a fatty substance that plays a vital role in the functioning of our body. It is required for the production of hormones, vitamin D, and digestive enzymes. However, too much of anything can be harmful, and the same goes for cholesterol. High cholesterol levels can increase the risk of various health problems, including heart disease and stroke.
Cholesterol is carried through the bloodstream by lipoproteins. Low-density lipoproteins (LDL) are commonly known as “bad” cholesterol, as they contribute to the buildup of plaque in the arteries. On the other hand, high-density lipoproteins (HDL) are referred to as “good” cholesterol, as they help remove excess cholesterol from the bloodstream.
Several factors can contribute to high cholesterol levels. Here are five factors that can increase unhealthy cholesterol levels.
1. Unhealthy Diet
A diet high in saturated and trans fats can increase LDL cholesterol levels in the bloodstream. Saturated fats are commonly found in animal products like meat and dairy, as well as in some plant-based foods like coconut oil and palm oil. Trans fats are commonly found in processed foods like chips, cookies, and fried foods.
On the other hand, a diet rich in fruits, vegetables, whole grains, and lean protein sources can help reduce LDL cholesterol levels in the bloodstream.
2. Lack of Physical Activity
Physical activity is essential for maintaining good health. Regular exercise helps increase HDL cholesterol levels in the bloodstream, which in turn helps remove excess cholesterol from the bloodstream. In contrast, a lack of physical activity can lead to a decrease in HDL cholesterol levels and an increase in LDL cholesterol levels.
The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of vigorous-intensity aerobic exercise per week, or a combination of both, to maintain good health.

3. Smoking
Smoking is a significant risk factor for heart disease and stroke. It can also contribute to high cholesterol levels by damaging the walls of the arteries, which can lead to the buildup of plaque.
Moreover, smoking can decrease HDL cholesterol levels in the bloodstream and increase LDL cholesterol levels.
4. Obesity
Obesity is a significant risk factor for high cholesterol levels. It can contribute to an increase in LDL cholesterol levels and a decrease in HDL cholesterol levels. Moreover, obesity can lead to the development of other health problems like diabetes, high blood pressure, and heart disease.
Maintaining a healthy weight through a balanced diet and regular exercise can help reduce the risk of high cholesterol levels and other health problems.
5. Genetics
Genetics can play a role in high cholesterol levels. Some people may have a genetic predisposition to high cholesterol levels, which can increase their risk of developing heart disease and stroke.
Familial hypercholesterolemia (FH) is a genetic condition that affects around 1 in 500 people. People with FH have a high level of LDL cholesterol in their bloodstream from birth, which increases their risk of developing heart disease at an early age.
High cholesterol levels can increase the risk of various health problems, including heart disease and stroke. Several factors can contribute to high cholesterol levels, including an unhealthy diet, lack of physical activity, smoking, obesity, and genetics.

Making lifestyle changes, such as adopting a healthy diet and engaging in regular physical activity, can help reduce the risk of high cholesterol levels and other health problems. It is also essential to get regular check-ups and screenings to monitor cholesterol levels and manage any underlying health conditions.
