When to consult a doctor for cholesterol?

If you have a family history of heart disease

If you have a family history of high cholesterol or heart disease, are over 45 years of age (or over 30 for Aboriginal and Torres Strait Islander people), regular health checks are needed.

If you experience heart disease symptoms

Consult a doctor promptly if you notice chest pain, breathlessness, numbness, or coldness in your hands or feet, as these may signal underlying cardiovascular issues.

If there are changes in your health

Medical review is essential if you already have high cholesterol or heart disease and are making lifestyle changes, or if you develop new health conditions such as hypothyroidism.

Causes and complications

Cholesterol causes

Diet: Eating foods high in saturated fats and trans fats, like red meat, full-fat dairy, fried and processed foods
Lack of exercise: Being sedentary can lower HDL (good) cholesterol
Obesity: Excess weight can raise LDL cholesterol and lower HDL cholesterol.
Smoking: Smoking damages blood vessels and lowers HDL cholesterol.
Genetics: Family history can play a significant role
Underlying conditions: Diabetes, hypothyroidism, and certain medications can also elevate cholesterol.

Cholesterol complications

Chest pain or angina: Due to blocked arteries, which can reduce blood flow to the heart.
Shortness of breath: Caused by reduced blood flow or heart strain.
Numbness or coldness in extremities: This can happen when there’s reduced blood circulation in the arms or legs.
Stroke or heart attack: Severe outcomes due to blocked arteries.

Types and prevention

Types of cholesterol

Cholesterol travels through the bloodstream in two main types:

Low-Density Lipoprotein (LDL): Often called “bad” cholesterol, it can build up in the walls of your arteries, leading to hardening and narrowing that may increase the risk of heart attacks and strokes.
High-Density Lipoprotein (HDL): Known as “good” cholesterol, it helps remove LDL from your bloodstream, transporting it to the liver to be broken down and removed from the body.

Prevention of cholesterol

Eat a healthy diet (rich in fruits, vegetables, whole grains, and healthy fats).
Exercise regularly or lose weight if needed.
Avoid smoking and limit alcohol consumption.
Take medications if prescribed by your doctor.
Talk to GP to manage cholesterol early symptoms.
