LDL (Low-density lipoprotein) is often referred to as "bad cholesterol" because it can accumulate in the arteries, forming plaques that narrow the blood vessels and increase the risk of heart disease.

HDL (High-density lipoprotein) is known as "good cholesterol" because it helps remove cholesterol from the arteries and transport it back to the liver for elimination.

Consuming a diet high in saturated fats, found in animal products and certain processed foods, can contribute to elevated cholesterol levels.

Triglycerides are the main form of fat stored in the body and serve as an energy reserve. They are broken down into fatty acids and glycerol to provide energy when needed.

Polycystic ovary syndrome (PCOS) is a hormonal disorder that can lead to elevated triglyceride levels, among other metabolic abnormalities.

For adults, the optimal target range for LDL cholesterol is generally considered to be below 100 mg/dL (milligrams per deciliter) to reduce the risk of heart disease.

To lower triglyceride levels, it is beneficial to engage in regular physical activity, limit alcohol intake, and reduce consumption of processed foods, refined carbohydrates, and added sugars.

Higher HDL cholesterol levels are generally considered beneficial, with target levels above 40 mg/dL for men and 50 mg/dL for women.

Statins, such as atorvastatin, simvastatin, and rosuvastatin, are a class of medications primarily used to lower LDL cholesterol levels and reduce the risk of heart disease.

Saturated fats are primarily found in animal-based foods like fatty meats, poultry with skin, full-fat dairy products, and processed foods containing tropical oils (e.g., palm oil, coconut oil).

Salmon is a rich source of omega-3 fatty acids, particularly EPA and DHA, which have been shown to have beneficial effects on triglyceride levels.

The recommended daily intake of dietary cholesterol for adults is generally less than 200 mg to help maintain healthy cholesterol levels.

Hypothyroidism, Cushing's syndrome, and diabetes mellitus can all contribute to elevated cholesterol levels due to hormonal imbalances or metabolic abnormalities.

For adults, the optimal target range for triglycerides is generally considered to be below 150 mg/dL to reduce the risk of heart disease.

To lower LDL cholesterol levels, it is beneficial to engage in regular physical activity, maintain a healthy weight, and consume a diet rich in soluble fiber, such as oats, beans, and apples.
