What can raise cholesterol levels?

There are various factors that can raise cholesterol levels, including both lifestyle-related and genetic factors. Here are some of the key factors:

1. Certain Fatty Foods:

- Saturated fat: Found primarily in animal products such as red meat, full-fat dairy products, and some plant-based oils (e.g., palm, coconut oil). A high intake of saturated fat can increase LDL (bad) cholesterol and contribute to plaque buildup in the arteries.

- Trans fat: Found in processed and baked goods, margarine, fried foods, and some packaged products. Trans fat is particularly harmful as it raises both LDL and lowers HDL (good) cholesterol.

2. High-Cholesterol Foods:

Consuming foods high in dietary cholesterol, such as egg yolks, certain shellfish, and organ meats, can contribute to elevated cholesterol levels.

3. Obesity and Overweight:

Excess weight, particularly abdominal fat, is associated with higher cholesterol levels.

4. Lack of Physical Activity:

A sedentary lifestyle can decrease HDL cholesterol and increase LDL cholesterol.

5. Smoking:

Smoking damages the blood vessel walls and promotes inflammation, which can contribute to higher cholesterol levels.

6. Diabetes and Insulin Resistance:

Diabetes and insulin resistance are linked to increased LDL and decreased HDL cholesterol levels.

7. Certain Medications:

Some medications, including diuretics, beta-blockers, corticosteroids, and progestins, can raise cholesterol levels as a side effect.

8. Hypothyroidism:

An underactive thyroid gland can lead to higher cholesterol levels.

9. Genetics:

Some genetic conditions can impact cholesterol levels, including familial hypercholesterolemia (FH), which causes high levels of LDL cholesterol.

10. Poorly Controlled Stress:

Chronic stress can negatively impact cholesterol levels by elevating harmful stress hormones.

It's important to note that high cholesterol doesn't usually have noticeable symptoms, which is why regular blood lipid screenings are crucial for monitoring cholesterol levels and managing cardiovascular health.
