What causes elevated blood lipids, especially high cholesterol?
This article lists the general causes of excess cholesterol in the blood. However, if you or someone around you is suffering from high cholesterol, contact a specialist doctor for diagnosis, counseling, and appropriate treatment according to the situation.
7 Causes of High Cholesterol
What are the leading causes of excess cholesterol in the blood? Here are some of the causes of high cholesterol:
1. Unhealthy Diet:
Consuming a diet rich in saturated fats and trans fats along with processed foods can have a significant impact on your cholesterol levels. These dietary choices promote the production of low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol, which can build up in the arteries. Foods such as red meat, high-fat dairy products, fried foods, and commercial baked goods are common culprits.
2. Sedentary Lifestyle:
Lack of physical activity and a sedentary lifestyle can contribute to higher cholesterol levels. Regular exercise helps raise high-density lipoprotein (HDL) cholesterol, or “good” cholesterol levels, which helps remove excess LDL cholesterol from the bloodstream. Without regular exercise, HDL cholesterol levels may remain low, leading to an imbalance between the two types of cholesterol.
3. Age, Gender, Genetics, and Family History:
Some people may have a genetic predisposition to high cholesterol levels. Familial hypercholesterolemia is an inherited condition characterized by high LDL levels of cholesterol from a young age. A family history of high cholesterol or cardiovascular disease increases the likelihood of high cholesterol levels in their offspring. Also, as a person ages, cholesterol levels tend to naturally go up. This is especially true for postmenopausal women when their estrogen levels drop. Estrogen has a protective effect on cholesterol levels, so its decrease can lead to higher LDL cholesterol levels and lower HDL cholesterol levels.
4. Certain Medications:
Certain medications can lead to an increase in cholesterol in some people, under certain circumstances. For example, the use of certain antiviral drugs, corticosteroids, or certain types of immunosuppressive drugs may increase LDL cholesterol levels.
5. Weight:
Being overweight or obese is closely related to higher levels of cholesterol. Excess weight, especially belly fat, promotes LDL cholesterol production and reduces HDL cholesterol levels. Additionally, obesity usually goes hand in hand with a bad diet and a sedentary lifestyle, so together, it’s a bad combination to have.
6. Smoking and Alcohol Consumption:
Smoking damages blood vessels and lowers HDL cholesterol levels. This increases the risk of cholesterol accumulation in the arteries. Similarly, excessive alcohol consumption can increase triglyceride levels as well.
7. Certain Medical Conditions:
Certain medical conditions, such as diabetes, hypothyroidism, and kidney disease, can lead to high cholesterol levels. These conditions can disrupt the normal metabolism of cholesterol and increase the production of LDL cholesterol. Also, ongoing stress sometimes leads to various deleterious bodily effects that, in turn, lead to an increase in cholesterol levels.
