There are two main types of cholesterol:

• LDL (Low-Density Lipoprotein) – Known as 'bad' cholesterol, high levels can lead to plaque buildup in the arteries.
• HDL (High-Density Lipoprotein) – Known as 'good' cholesterol, helps remove excess cholesterol from the bloodstream.

A Lipid Profile Test measures:

• Total Cholesterol
• LDL (bad cholesterol)
• HDL (good cholesterol)
• Triglycerides (another type of fat in the blood that can increase heart disease risk)

Causes of High Cholesterol

High cholesterol can be caused by a combination of lifestyle factors, genetics, and underlying health conditions. Common causes include:

• Unhealthy diet – High intake of saturated and trans fats, found in processed foods and fried items.
• Lack of exercise – Physical inactivity can lower HDL (good cholesterol) and raise LDL (bad cholesterol).
• Smoking – Reduces good cholesterol and damages blood vessels, increasing plaque buildup.
• Excess alcohol consumption – Can raise triglyceride levels and contribute to high cholesterol.
• Being overweight or obese – Increases LDL cholesterol and lowers HDL cholesterol.
• Family history – Some people inherit a genetic condition called familial hypercholesterolemia, which causes high cholesterol.
• Underlying conditions – Conditions such as diabetes, hypothyroidism, and kidney disease can contribute to high cholesterol levels.

Signs & Symptoms of High Cholesterol

High cholesterol does not usually cause symptoms, which is why regular testing is important. It is often detected through a blood test before it leads to serious health conditions such as:

• Heart disease
• Stroke
• High blood pressure
• Narrowed or blocked arteries (atherosclerosis)

Vitamins & Supplements for Healthy Cholesterol Levels

Certain vitamins and supplements may support healthy cholesterol levels and heart health:

• Omega-3 Fatty Acids – Found in fish oil, helps lower triglycerides and reduce inflammation.
• Niacin (Vitamin B3) – Can help increase HDL (good cholesterol) and lower LDL (bad cholesterol).
• Plant Sterols & Stanols – Found in fortified foods and supplements, can help lower LDL cholesterol.
• Soluble Fiber (e.g., Psyllium Husk, Beta-Glucan) – Helps reduce cholesterol absorption in the gut.
• Coenzyme Q10 (CoQ10) – May support heart health, especially for those on cholesterol-lowering medications.– Contains antioxidants that may help lower LDL cholesterol.– Some studies suggest garlic may help modestly reduce cholesterol levels.

If your cholesterol levels are high, you can reduce your risk of complications by:

• Eating a heart-healthy diet – Increase fiber-rich foods, reduce saturated fats, and limit processed foods.
• Exercising regularly – At least 30 minutes a day can help raise good cholesterol and lower bad cholesterol.
• Maintaining a healthy weight – Losing even a small amount of weight can improve cholesterol levels.
• Quitting smoking – Improves HDL (good cholesterol) and overall heart health.
• Limiting alcohol intake – Excess alcohol can raise triglyceride levels.
• Taking prescribed medications – If recommended by your GP, cholesterol-lowering medications (e.g., statins) can help manage high cholesterol.

When to See a Doctor

You should speak to your GP if:

• You have a family history of high cholesterol or heart disease
• You have been diagnosed with high blood pressure, diabetes, or obesity
• You have previously high cholesterol readings and need follow-up testing
