Why High Cholesterol Matters

Should I manage my total cholesterol of 305 just for my doctor?

High cholesterol puts you at risk for heart disease and stroke, leading causes of death in the U.S. High levels of LDL cholesterol can contribute to plaque buildup on the walls of the arteries, narrowing the arteries and restricting blood flow. If some of this plaque breaks off and gets stuck in a narrowed artery, it can block the artery and cut off blood supply to the heart or brain, resulting in heart attack or stroke.

Why Should I Lower My Cholesterol

Evidence strongly indicates that high cholesterol can increase the risk of:

This is because cholesterol can build up in the artery wall, restricting the blood flow to your heart, brain and the rest of your body. It also increases the risk of a blood clot developing somewhere in your body.

Your risk of developing coronary heart disease also rises as your blood’s cholesterol level increases. This can cause pain in your chest or arm during stress or physical activity .

Symptoms Of High Cholesterol

Often, there are no specific symptoms of high cholesterol. You could have high cholesterol and not know it.

If you have high cholesterol, your body may store the extra cholesterol in your arteries. These are blood vessels that carry blood from your heart to the rest of your body. A buildup of cholesterol in your arteries is known as plaque. Over time, plaque can become hard and make your arteries narrow. Large deposits of plaque can completely block an artery. Cholesterol plaques can also break apart, leading to formation of a blood clot that blocks the flow of blood.

A blocked artery to the heart can cause a heart attack. A blocked artery to your brain can cause a stroke.

Many people dont discover that they have high cholesterol until they suffer one of these life-threatening events. Some people find out through routine check-ups that include blood tests.

Understanding Your Cholesterol Results

When you get your cholesterol result from your doctor, its split into a variety of different measurements.

  • TC which stands for total cholesterol and should ideally be below 5 millimoles per litre of blood
  • LDL , which should be less than 3mmols/l
  • HDL . This should read more than 1mmol/l for men and 1.2 mmol/l for women
  • A fasting triglyceride sample, which should be 2 mmols/l or less
  • A non-fasting triglyceride result, which should be 4 mmols/l or less.

Total cholesterol of 5.8mmols/l is higher than recommended, but could be reduced with simple diet and lifestyle changes rather than medical treatment. Medical treatment would only be appropriate if the level was much higher.

Cholesterol Levels For Adults

At
  • Total cholesterol levels less than 200 milligrams per deciliter are considered desirable for adults. A reading between 200 and 239 mg/dL is considered borderline high and a reading of 240 mg/dL and above is considered high.
  • LDL cholesterol levels should be less than 100 mg/dL. Levels of 100 to 129 mg/dL are acceptable for people with no health issues but may be of more concern for those with heart disease or heart disease risk factors. A reading of 130 to 159 mg/dL is borderline high and 160 to 189 mg/dL is high. A reading of 190 mg/dL or higher is considered very high.
  • HDL levels should be kept higher. A reading of less than 40 mg/dL is considered a major risk factor for heart disease. A reading from 41 mg/dL to 59 mg/dL is considered borderline low. The optimal reading for HDL levels is of 60 mg/dL or higher.

How Is The Total Cholesterol Or Blood Cholesterol Test Done

A blood test is a routine test. A phlebotomist is the person whose job it is to draw blood. Blood is usually drawn from the vein in your arm. You will sit down and the phlebotomist will wrap a rubber band around your upper arm so that the vein in your elbow sticks out. Then they will use a needle to puncture the vein and remove blood. The blood is sent to the lab to be examined.

Youve probably been at health fairs where testing is offered. In that case, the person performing the test takes a drop of blood from your finger. The finger stick test uses a small blade to poke a hole in the tip of your finger to get the blood.

Can High Cholesterol Be Prevented Or Avoided

Making healthy food choices and exercising are two ways to reduce your risk of developing high cholesterol.

Eat fewer foods with saturated fats . Choose healthier fats. This includes lean meats, avocados, nuts, and low-fat dairy items. Avoid foods that contain trans fat . Look for foods that are rich in omega-3 fatty acids. These foods include salmon, herring, walnuts, and almonds. Some egg brands contain omega-3.

Exercise can be simple. Go for a walk. Take a yoga class. Ride your bike to work. You could even participate in a team sport. Aim to get 30 minutes of activity every day.

There Are Two Main Types Of Cholesterol

The two main lipoproteins responsible for transporting cholesterol are low-density lipoprotein and high-density lipoprotein .

LDL cholesterol is whats known as bad cholesterol. Too much LDL cholesterol leads to fatty buildups that clog arteries atherosclerosis. Narrows arteries make it difficult for blood to travel through the body, and it makes your heart work harder to pump blood. Excess LDL cholesterol increases your risk for heart disease, heart attack, stroke, peripheral artery disease.

In general, you want lower levels of low-density lipoprotein cholesterol.

HDL cholesterol is commonly referred to as good cholesterol. Research shows a correlation between higher HDL levels and a lower risk for heart disease. High-density lipoproteins help carry LDL cholesterol through the blood and back to the liver. The liver then breaks down LDL cholesterol, allowing the body to remove it as waste.

In general, you want higher levels of high-density lipoprotein cholesterol.

Cholesterol: The Good And The Bad Of It

What should be your Ideal Cholesterol Level? Dr. Hemant Madan

HDL High-density lipoprotein

  • Makes up 20%30% of total cholesterol
  • The “good” cholesterol
  • Moves cholesterol from arteries to the liver.

LDL Low-density lipoprotein

  • Makes up 60%70% of total cholesterol
  • Main form of “bad” cholesterol
  • Causes build-up of plaque inside arteries.

VLDL Very-low-density lipoprotein

  • Makes up 10%15% of total cholesterol
  • With LDL, the main form of “bad” cholesterol
  • A precursor of LDL.

LDL cholesterol. The LDL measurement is usually considered the most important for assessing risk and deciding on treatment. The definition of a healthy level keeps on getting lower. For people at low risk of heart disease, an LDL of less than 100 is desirable, However, people at higher risk of heart disease, an LDL of less than 70 or perhaps even lower is considered “optimal.” Some experts say that an LDL of less than 70 would be a healthy LDL goal for all of us.

Your LDL is computed by plugging the measurements for total cholesterol, HDL, and triglycerides into a: LDL = Total cholesterol HDL . LDL can also be measured directly in a non-fasting blood sample.

You have to fast for about 10 hours before the test because triglyceride levels can shoot up 20%30% after a meal, which would throw off the equation. Alcohol also causes a triglyceride surge, so you shouldn’t drink alcohol for 24 hours before a fasting cholesterol test.

What Are The Symptoms Of High Cholesterol

Lifestyle factors include:

  • an unhealthy diet– eating too much saturated fat is thought to increase levels of LDL or bad cholesterol
  • lack of exercise – this can also increase your levels of LDL
  • obesity – being overweight often means you also have higher levels of LDL cholesterol and triglycerides, and a lower level of the good HDL.
  • drinking too much alcohol
  • smoking – if you smoke, a chemical in cigarettes called acrolein stops the good HDL from moving fatty deposits to your liver

Underlying conditions

  • kidney disease
  • transient ischaemic attack – or a mini stroke
  • peripheral arterial disease

The Risks Of High Cholesterol

Managing your cholesterol levels is important because high cholesterol can lead to a serious condition known as atherosclerosis. This can happen when high cholesterol is left untreated, causing plaque to build up in your arteries.

Over time, plaque build-up can narrow your arteries, limiting blood flow. This can even put you at risk for developing blood clots. Atherosclerosis also puts you at risk for life-threatening complications like a stroke, heart attack, chronic kidney disease, peripheral vascular disease, and angina.

Why Is Cholesterol Needed By The Body

Overview

With all of the bad publicity cholesterol gets, people are often surprised to learn that its actually necessary for our existence.

For some people, diet and lifestyle changes are not enough. High blood cholesterol levels often have a genetic component. Some people inherit altered genes that cause high cholesterol and this cannot usually be changed sufficiently by lifestyle or diet.

If you are at risk of coronary heart disease and your LDL cholesterol level doesnt drop after scrupulous attention to diet, your doctor may recommend medications to force your blood LDL levels down. Cell cholesterol levels, however, remain normal, so lowering blood cholesterol has no effect on most cell metabolic processes.

Some people get muscle aches from statins, which are the most commonly used medication to lower blood cholesterol. However, diet and exercise will still be important, even if you are taking medication. Your doctor may also refer you to a specialist who treats cardiovascular disease.

Can Bad Cholesterol Levels Be Too Low Can Good Cholesterol Levels Be Too High

It isnt often that people have bad cholesterol that is too low or good cholesterol that is too high. There are studies being done that suggest that extremes of any kind are not healthy for everyone.

Even though there is no clear-cut number about what LDL level is too low, levels under 40 mg/dL may be associated with certain health issues, including depression/anxiety, and hemorrhagic stroke.

However, there is data from clinical trials to support that there is no evidence of harm when LDLs remain < 40mg/dl on statin therapy.

In some cases, genetic conditions can cause you to have very low cholesterol levels. In other cases, nutritional problems, some cancers, hypothyroidism and certain infections can also cause low cholesterol levels. In any of these types of situations, the underlying issues need to be addressed.

In terms of having too much of a good thing, researchers are studying the effects of too much HDL, the good cholesterol. No conclusions have been reached, but there have been studies into the possible relationship between high HDL and cancer, and a greater risk of heart attack among the high risk. Excessively high HDL may be dysfunctional HDL and not protective.

What Are Normal Cholesterol Levels For Teens And Children

Certain risk factors can put a child at risk for having high cholesterol. This includes diabetes, obesity, or a family history of high cholesterol. In contrast, Healthline states that children who are physically active, eat a healthy diet, are not overweight, and dont have a family history are at a lower risk. Here are the normal cholesterol levels for teens and children :

  • Total cholesterol: less than 170 mg/dL
  • Non-HDL cholesterol: less than 120 mg/dL
  • LDL cholesterol: less than 110 mg/dL
  • HDL cholesterol: more than 45 mg/dL

Keep in mind, all children should have their cholesterol checked between the ages of 9 and 11 and then again at 17 and 21. That said, children who have risk factors for high cholesterol should have theirs checked at ages 2 and 8 and then again between ages 12 and 16.

What Factors Affect Cholesterol Levels

Total Cholesterol

A variety of factors can affect your cholesterol levels. They include:

  • Diet: Saturated fat, trans fat and cholesterol in the food you eat increase cholesterol levels. Try to reduce the amount of saturated fat, trans fat and cholesterol in your diet. This will help lower your blood cholesterol level. Saturated and trans fat have the most impact on blood cholesterol.
  • Weight: In addition to being a risk factor for heart disease, being overweight can also increase your triglycerides. Losing weight may help lower your triglyceride levels and raise your HDL.
  • Exercise: Regular exercise can lower total cholesterol levels. Exercise has the most effect on lowering triglycerides and raising HDL. You should try to be physically active for 30 minutes on most days of the week.
  • Age and sex: As we get older, cholesterol levels rise. Before menopause, women tend to have lower total cholesterol levels than men of the same age. After menopause, however, womens LDL levels tend to rise and HDL can drop.
  • Heredity: Your genes partly determine how much cholesterol your body makes. High blood cholesterol can run in families.

Cholesterol is both good and bad. At normal levels, it is an essential substance for the body. However, if concentrations in the blood get too high, it becomes a silent danger that puts people at risk of heart attack.

Cholesterol is present in every cell of the body and has important natural functions when it comes to digesting foods, producing hormones, and generating vitamin D. The body produces it, but people also consume it in food. It is waxy and fat-like in appearance.

There are two types of cholesterol:

  • low-density lipoproteins , or bad cholesterol
  • high-density lipoproteins , or good cholesterol

In this article, we will explain the role of cholesterol. We will also discuss the causes of high cholesterol, and its symptoms, treatment, and prevention.

The Pros And Cons Of Total Cholesterol Hdl Ldl And Triglyceride Testing

Total Cholesterol Levels Be Too Low, You Must Check its ...

Time to get your cholesterol checked. Okay, but which test should you get? It’s not so simple anymore. Here is a rundown of some of the choices and their pros and cons:

Total cholesterol. This is the simplest and least expensive test. The test doesn’t require any sophisticated lab work, either. The simple, do-it-yourself home cholesterol tests measure total cholesterol.

But total cholesterol includes both “good” high-density lipoprotein cholesterol, and the “bad” varieties, chiefly low-density lipoprotein and very-low-density lipoprotein . So, if your total cholesterol is in the desirable category, it’s possible that you may have unhealthy levels of HDL and LDL and VLDL . Think of total cholesterol as a first glimpse, a peek. Doctors are not supposed to make any treatment decisions based on this number alone.

Cholesterol levels can be lowered by stress or infection. An injury, cancer, stroke, or heart attack may have the same effect. So, if your cholesterol levels are unusually high or low, your doctor will probably want to repeat the test some weeks later. Abnormal readings may also lead to tests for other medical problems.

HDL cholesterol. HDL wins its laurels as the “good” cholesterol because it sponges up cholesterol from blood vessel walls and ferries it to the liver for disposal. In contrast, LDL deposits the harmful fat in vessel walls.

An HDL level of 60 or above is associated with a lower risk of heart disease, and below 40 is associated with a higher risk.

Does Age Make A Difference To Recommended Cholesterol Levels

No, recommended cholesterol levels do not change based on age. It was once thought that high cholesterol becomes less of a problem as one ages. However, there is now good evidence that lowering high cholesterol is of benefit even in the elderly.

Previously, there was also concern that some cholesterol-lowering drugs like statins may interfere with ones cognitive function and that this might be more of an issue in the elderly. This has now been debunked. Nevertheless, it is worth starting with a low dose and gradually increasing to avoid any potential side effects.
