What Are The Good And Bad Of Cholesterol

Cholesterol can be a confusing topic, but as we get older it is a topic that we can’t avoid. Let’s clear up what are the good and bad of cholesterol and how you can live a healthier life.

The Good And Bad Of Cholesterol – What You Need To Know

What Is Cholesterol?

Cholesterol is a waxy, fat-like substance that your body needs to stay healthy believe it or not. But when there is too much cholesterol in the blood, it builds up on the walls of the arteries.

Over time, this buildup, called plaque, causes hardening and narrowing of the arteries so that blood flow is slowed down or blocked.

If the blood supply to a portion of the heart is completely blocked, the result is, unfortunately, a heart attack.

What Is The Difference Between Good And Bad Cholesterol?

The liver and other cells in the body make about 75% of the body’s cholesterol. The other 25% comes from animal products in our diets.

Many people inherit genes from their parents that increase cholesterol levels. This is called familial high cholesterol.

There are two types of cholesterol:

  • Good cholesterol or HDL cholesterol. This is the type that helps prevent the bad cholesterol from getting lodged in the walls of the arteries.
  • Bad cholesterol or LDL cholesterol. This is the type that clogs the arteries and increases the risks of heart attacks and strokes.

Triglycerides are another form of fat in the blood that, when elevated are also associated with heart attacks and strokes.

Too little good cholesterol, as well as too much bad cholesterol, increases the risk for heart attacks and strokes.

How Do I Know If I Have Too Much Bad Cholesterol?

A doctor can perform a simple blood test, and this will provide you with information relating to your total cholesterol, LDL cholesterol, HDL cholesterol and Triglycerides.

Unfortunately, high cholesterol in itself does not show any symptoms, so many people are unaware that their cholesterol levels are too high until it is too late.

Everyone should have their cholesterol levels checked at least once in young adulthood and every year if you show problems with cholesterol or as you get older.

To find out how your cholesterol levels affect your risk of heart disease, your doctor will also take into account other risk factors like your age, family history, smoking and blood pressure.

These Are Considered Healthy Cholesterol Levels:

Total Cholesterol – less than 5 mmol/L

LDL Cholesterol – less than 3 mmol/L

HDL Cholesterol (women) – greater than 1.2 mmol/L

HDL Cholesterol (men) – greater than 1.0 mmol/L

Triglycerides – less than 1.7 mmol/L

How Do I Know If I Am At Risk For A Heart Attack Or A Stroke?

Very high-risk individuals include those with:

  • A history of heart attack, stroke or circulatory disease
  • Diabetes mellitus
  • Kidney Disease
  • Familial High Cholesterol

In addition to high cholesterol, there are a number of other factors that increase the risks associated with heart disease:

  • Smoking
  • Overweight/obesity
  • High Blood Pressure
  • Family history of heart disease (male before 55 years of age and female before 60 years of age)
  • Advancing age
  • Male gender

How Can I Lower My Cholesterol?

Lowering your cholesterol levels is very important for people of all ages with and without established heart disease.

Cholesterol levels can almost always be lowered with a combination of diet, weight loss, exercise and medications.

As cholesterol levels fall, so does the risk of developing heart disease.

This may result in a lower risk of suffering a heart attack or a stroke.

It is not too late if heart disease is already present because cholesterol-lowering treatment can be lifesaving.

What Medicines Lower Cholesterol?

There are many medicines available to help lower cholesterol levels. Your doctor will recommend medicine or a combination of medicines based on your cholesterol levels and other individual factors.

Remember all medication normally has side effects, so the aim would be to try to get your lifestyle choices right so that you are not subjected to taking meds for the rest of your life.

Statins – this medicine decreases the body’s production of cholesterol. It can reduce LDL cholesterol and triglycerides. It can also slightly increase HDL cholesterol levels.
