What Causes High Cholesterol? Understanding the Risk Factors You Can (and Can’t) Control

High cholesterol is one of the most common yet misunderstood health conditions. Many people assume it only affects those who eat poorly, but the reality is far more complex. Understanding what causes high cholesterol is the first step toward managing it effectively.

Cholesterol Basics: Not All Bad

Before discussing causes, it’s important to understand that cholesterol itself isn’t harmful — your body needs it to build cell membranes, produce hormones, and synthesise vitamin D. The problem arises when there’s too much LDL (low-density lipoprotein) cholesterol circulating in your blood, which can deposit in artery walls and form dangerous plaques.

Types of Cholesterol

Type	Role	Ideal Level
LDL (“bad” cholesterol)	Carries cholesterol to arteries	Below 2.6 mmol/L
HDL (“good” cholesterol)	Carries cholesterol away from arteries	Above 1.0 mmol/L (men), 1.2 mmol/L (women)
Triglycerides	Stores excess energy from food	Below 1.7 mmol/L
Total cholesterol	Sum of all cholesterol types	Below 5.2 mmol/L

Controllable Causes of High Cholesterol

1. Diet

Your diet is the most modifiable risk factor. Foods high in saturated fats (red meat, full-fat dairy, coconut oil, palm oil) and trans fats (fried foods, processed snacks, margarine) directly raise LDL cholesterol.

In Malaysia, common dietary culprits include:

• Generous use of coconut milk (santan) in curries, rendang, and nasi lemak
• Deep-fried snacks (goreng pisang, cucur udang, keropok)
• High consumption of red meat and organ meats
• Processed foods and instant noodles
• Sugary drinks that raise triglycerides

2. Physical Inactivity

A sedentary lifestyle lowers HDL cholesterol and allows LDL to accumulate. Regular exercise boosts HDL and helps your body metabolise cholesterol more efficiently.

3. Excess Weight

Being overweight or obese tends to raise LDL and triglycerides while lowering HDL. Abdominal fat (visceral fat) is particularly harmful as it triggers inflammatory processes that worsen cholesterol profiles.

4. Smoking

Smoking doesn’t directly raise cholesterol numbers, but it damages blood vessel walls, making them more susceptible to LDL deposits. It also lowers HDL cholesterol, removing a key protective factor.

5. Excessive Alcohol

Heavy drinking raises triglycerides and total cholesterol, while also damaging the liver — the organ responsible for processing cholesterol.

Uncontrollable Risk Factors

1. Genetics (Familial Hypercholesterolaemia)

Some people inherit genes that cause their liver to produce too much cholesterol or fail to clear LDL efficiently. Familial hypercholesterolaemia (FH) affects about 1 in 250 people and can cause dangerously high cholesterol from birth, regardless of diet or lifestyle.

2. Age

Cholesterol levels naturally rise with age. Women often see a jump after menopause due to declining oestrogen levels, which previously helped keep LDL in check.

3. Sex

Before menopause, women generally have lower LDL than men of the same age. After menopause, however, women’s LDL levels often surpass men’s.

4. Certain Medical Conditions

• Hypothyroidism (underactive thyroid)
• Chronic kidney disease
• Diabetes (especially Type 2)
• Liver disease

A Comprehensive Management Approach

Since high cholesterol often results from multiple factors, the most effective management combines several strategies:

1. Dietary improvements — Increase fiber, reduce saturated fats
2. Regular exercise — At least 150 minutes per week
3. Weight management — Achieve and maintain a healthy BMI
4. Quit smoking — Benefits begin almost immediately
5. Natural supplementation — Evidence-based ingredients like oat beta glucan
6. Medical treatment — Statins when prescribed by your doctor

CX Cardio Xupport addresses the cholesterol challenge with Swiss oat beta glucan — clinically validated to lower LDL — while also tackling related cardiovascular risk factors through nattokinase (blood clot prevention), beetroot (blood pressure support), and soymilk powder (antioxidant protection). This synergistic formula recognises that cholesterol rarely acts alone in threatening heart health.
