High LDL cholesterol ("bad" cholesterol) is most commonly caused by an unhealthy lifestyle, but genetics, other medical conditions, and certain medications can also contribute.
Here's a more detailed breakdown:
-
Unhealthy Lifestyle: This is the most frequent culprit.
- Poor Diet: A diet high in saturated and trans fats, found in red meat, processed foods, and fried foods, increases LDL cholesterol.
- Lack of Physical Activity: Insufficient exercise can lead to higher LDL levels.
- Obesity: Being overweight or obese is often linked to elevated LDL cholesterol.
- Smoking: Smoking damages blood vessels and can increase LDL cholesterol.
-
Genetics: Your genes play a significant role in how your body processes cholesterol. Familial hypercholesterolemia is a genetic disorder that causes very high LDL levels.
-
Medical Conditions: Certain health problems can impact LDL cholesterol levels.
- Hypothyroidism (Underactive Thyroid): This condition can lead to higher LDL cholesterol.
- Chronic Kidney Disease: Impaired kidney function can affect cholesterol metabolism.
- Diabetes: High blood sugar can damage arteries and contribute to higher LDL levels.
- Liver Disease: The liver plays a critical role in cholesterol processing.
-
Medications: Some medications can increase LDL cholesterol as a side effect.
- Anabolic Steroids
- Progestins
- Corticosteroids
In summary, elevated LDL cholesterol is frequently a result of dietary and lifestyle choices, but it's important to consider potential genetic factors, underlying medical conditions, and the medications you're taking. Consulting with a healthcare professional is crucial to determine the specific cause and develop an appropriate treatment plan.
