Question 1

What is the cornerstone of lifestyle modification for dyslipidemia?

Accepted Answer

Dietary fat reduction

Answer

Dietary fat reduction, particularly of saturated and trans fats, is a cornerstone of lifestyle modification for dyslipidemia. Limiting these unhealthy fats helps lower LDL cholesterol and improve overall lipid profiles. This, combined with increased fiber and plant-based foods, is crucial for cardiovascular health and managing lipid levels.

Question 2

Which type of exercise is most beneficial for lowering triglycerides?

Accepted Answer

Aerobic exercise

Answer

Regular aerobic exercise, such as brisk walking, jogging, swimming, or cycling, is highly effective in lowering triglyceride levels. It also helps increase HDL cholesterol and can contribute to weight loss, further improving lipid profiles. Consistency in aerobic activity is key to achieving these beneficial effects on lipids.

Question 3

What class of drugs is most commonly used to lower LDL cholesterol?

Accepted Answer

Statins

Answer

Statins are the most commonly prescribed and effective class of drugs for lowering LDL cholesterol. They work by inhibiting HMG-CoA reductase, an enzyme essential for cholesterol synthesis in the liver. This action reduces the liver's production of cholesterol and increases its uptake of LDL from the blood, significantly lowering LDL levels.

Question 4

How does niacin affect lipid levels?

Accepted Answer

Increases HDL

Answer

Niacin (nicotinic acid) is known to significantly increase HDL cholesterol levels, making it one of the most potent agents for this purpose. It also helps lower triglycerides and, to a lesser extent, LDL cholesterol. However, its use is often limited by side effects like flushing and gastrointestinal upset.

Question 5

Which medication binds bile acids in the intestine?

Accepted Answer

Bile acid sequestrants

Answer

Bile acid sequestrants, such as cholestyramine or colesevelam, work by binding to bile acids in the intestine, preventing their reabsorption. This forces the liver to use more cholesterol to synthesize new bile acids, thereby reducing cholesterol levels in the blood, particularly LDL. They are not absorbed systemically.
