Cholesterol

High cholesterol is common – but your overall heart and stroke risk is what guides the next step

Cholesterol is essential for the body – but too much of the wrong kind can contribute to fatty build‑up in the arteries (atherosclerosis), raising the risk of heart attack and stroke. In Australia, abnormal blood lipid levels are very common: the Australian Institute of Health and Welfare reports about two in three adults have abnormal blood lipids. The good news is that cholesterol and cardiovascular risk respond well to a practical plan: lifestyle changes, targeted monitoring, and medicines when they’re genuinely needed.

This page explains what cholesterol numbers mean, why doctors now focus on absolute cardiovascular risk (rather than a single result), and how Moss Vale Community Pharmacy can support you with safer choices and better follow‑through.

Know the emergency signs

Call 000 immediately for chest pain/pressure, shortness of breath, collapse, or symptoms of stroke (face droop, arm weakness, speech difficulty). Don’t drive yourself to hospital.

What Is Cholesterol?

Cholesterol is a waxy, fat‑like substance. Your body makes most of the cholesterol it needs, and some comes from food. Cholesterol travels in the blood attached to lipoproteins. A standard blood test (lipid profile) checks your cholesterol and triglycerides.

LDL (“bad”) cholesterol

LDL can deposit cholesterol in artery walls and contribute to plaque build‑up.

  • Lower is generally better, especially if you have higher overall risk.
  • LDL reduction is a key target for medicines such as statins.

HDL (“good”) cholesterol

HDL helps transport cholesterol away from arteries.

  • Higher HDL is generally favourable, but it’s only one part of risk.
  • Lifestyle factors (activity, smoking) influence HDL.

Triglycerides

Another type of blood fat influenced by diet, alcohol, weight and diabetes control.

  • Often improve with reduced alcohol and refined carbohydrates.
  • High levels can be linked with fatty liver and metabolic risk.

Total cholesterol & ratios

Total cholesterol is a broad number. Ratios (like total:HDL) can help estimate risk.

  • Your GP will interpret results alongside blood pressure, smoking, age, diabetes and other factors.

One number never tells the whole story

A single cholesterol result can’t capture your overall risk. That’s why Australian guidelines recommend estimating absolute cardiovascular disease (CVD) risk for many adults – using multiple risk factors together.

Absolute Cardiovascular Risk: The New Centre of Gravity

Modern Australian guidance recommends assessing your likelihood of heart attack or stroke over time, using tools such as the AusCVDRisk calculator. This approach combines information like age, blood pressure, cholesterol ratio, smoking status, diabetes, and other factors (and, in some cases, additional factors such as chronic kidney disease or family history). It helps decide when lifestyle changes are enough and when medicines are likely to prevent serious events.

  1. 1Get the basics: blood pressure, lipid profile, diabetes screen (if relevant), weight/waist, smoking status.
  2. 2Estimate risk: your GP can calculate absolute risk (often a 5‑year risk category) using AusCVDRisk tools and guidelines.
  3. 3Match the response: low risk often means lifestyle focus; higher risk may mean starting or intensifying medicines.

Important: some people are high risk without needing a calculator

Some conditions – such as familial hypercholesterolaemia (inherited high LDL), moderate‑to‑severe chronic kidney disease, or established cardiovascular disease – can place someone in a high‑risk group that needs medical management regardless of calculated score. If close relatives had early heart disease, ask your GP about inherited cholesterol conditions.

What Lowers Cholesterol in Real Life?

Heart‑healthy changes work best when they’re practical and sustainable. The Heart Foundation emphasises everyday actions such as choosing healthier fats, increasing fibre, moving more, and reducing smoking and excess alcohol.

  • Swap fats: choose unsaturated fats (olive oil, nuts, seeds, avocado) and limit trans fats and excess saturated fats.
  • Increase soluble fibre: oats, legumes, fruit and vegetables can help lower LDL.
  • Be active: regular activity improves lipid profile, blood pressure and insulin sensitivity.
  • Quit smoking: improves HDL and reduces vessel damage rapidly.
  • Limit alcohol: particularly if triglycerides are high.

Cholesterol Medicines: What to Know (Without the Hype)

For people at higher overall risk, medicines can meaningfully reduce heart attack and stroke risk by lowering LDL. Statins are commonly used, and there are other options if statins aren’t tolerated or targets aren’t achieved. The key is to use medicines when the expected benefit is high – and to stick with a plan that’s tailored to you.

Practical tips if you’re prescribed a statin

  • Take it exactly as prescribed and give it time – cholesterol lowering is about long‑term risk reduction.
  • Report muscle pain, weakness or unusual symptoms early – don’t stop suddenly without advice.
  • Ask us to check interactions, including with some antibiotics, antifungals and herbal products.
