Causes Of Changing Cholesterol Levels
Your cholesterol levels will change as you age, most likely increasing. There are a number of causes for changing cholesterol levels. They include:
Diet
If you eat foods high in saturated fat and cholesterol, it will make your total cholesterol level rise. The saturated fat is the main cause. This type of fat comes mainly from animal food products. You can find it in meat, dairy products, chocolate, baked goods, deep-fried foods, and processed foods. These foods make up a typical American diet, and consuming a lot of these foods is cautioned against.
Weight and physical activity
If you are overweight, your risk for heart disease increases and so do your cholesterol levels. Not being physically active also contributes to a risk for heart disease and high cholesterol levels. Exercising daily and losing weight can help lower your bad cholesterol, LDL, and increase your good cholesterol, HDL.
Smoking
Smoking can lower your good cholesterol, HDL, making it harder for your body to remove cholesterol from your arteries.
Age and gender
As you age, your total cholesterol levels increase. Women have lower total cholesterol levels than men of the same age. But when a woman goes through menopause, her bad cholesterol, LDL, tends to rise.
Heredity
Its important to know your family history of heart disease and cancers if applicable. How much cholesterol your body makes is partly determined by your genes. High cholesterol can run in your family.
Bad Cholesterol Numbersldl Is Your Enemy
As we mentioned above, HDLs job is to eliminate LDL, or low density lipoprotein. LDL is what builds up in artery walls, causing plaque and leading to heart disease and potential stroke. So those are the bad cholesterol numbers. As you might have guessed, we want these numbers to be as low as possible. The lower your LDL, the lower your risk of heart disease. Its not a direct correlation, as there are other factors including CRP levels, homocysteine and triglycerides, but generally speaking, the lower your LDL the better.
So what should those numbers be? The recommendations for LDL are much more specific than those for HDL. Anything less than 100 mg/dL is considered optimal. Up to about 129 mg/dL is close to ideal. Once you get to about 130 and above thats when it is considered high. If you are above 190 thats very high and is considered a risk.
Its interesting to note that if your LDL levels are high, it can be balanced out by high HDL levels. So its not so bad of you have elevated LDL concentrations if you have optimal HDL concentrations to counteract that. Thats why the cholesterol ratio is the most important number to look at.
We tend to focus on the total cholesterol number, i.e. anything over 200 mg/dL is considered a higher riskbut this number has become much less important as doctors are recognizing the importance of the concentrations of LDL and HDL, and not just the total amount.
What Is A Healthy Normal Cholesterol Level In The Uk
Your cholesterol level is measured in units called millimoles per litre of blood, often shortened to mmol/L.
It is recommended that healthy adults should have a total cholesterol level below 5 mmol/L. In the UK, three out of five adults have a total cholesterol level of 5 mmol/L or above, and the average cholesterol level is about 5.7 mmol/L, which can be a risk factor in the development of coronary heart disease.
However, its important to remember that as well as your cholesterol level, other factors such as smoking and high blood pressure are risk factors for the development of coronary heart disease.
The total cholesterol level includes LDL and HDL . The risk of coronary heart disease is particularly high if you have a high level of LDL cholesterol and a low level of HDL cholesterol. Individual levels of LDL and HDL cholesterol will vary and your doctor will be able to give you specific advice based on your own results.

Cholesterol moves throughout the body carried by lipoproteins in the blood. These lipoproteins include:
- Low-density lipoprotein is one of the two main lipoproteins. LDL is often called the bad cholesterol.
- High-density lipoprotein is the other main lipoprotein. HDL is often called the good cholesterol.
- Very-low-density lipoproteins are particles in the blood that carry triglycerides.

Ldl Cholesterol: ‘bad’ Cholesterol
Low-density lipoprotein cholesterol, often referred to as “bad” cholesterol, is the type that tends to deposit on the walls of the arteries. White blood cells combine with the LDL cholesterol, forming artery-narrowing plaque, which restricts blood flow. The optimal level of LDL cholesterol for most people is 100 mg/dL or lower. If you have heart disease, you may need to strive for LDL levels of 70 mg/dL or lower.

- 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.
How Is High Cholesterol Diagnosed

The measured total cholesterol level is made up of your LDL cholesterol, HDL cholesterol and 20% of triglycerides .
For an accurate reading, you should not eat or drink anything between nine and twelve hours before the sample is taken.
In Australia, cholesterol levels are measured in millimoles per litre .
The range below is a guide for a healthy blood cholesterol level.
- Total cholesterol should be between: 3.9 5.5 mmol/L
- HDL should be between: 0.9 2.1 mmol/L

How To Lower Cholesterol: Know Your Fats
The American Heart Association recommends that just 25% to 35% of your daily calories come from fats such as those found in fish, nuts, and vegetable oils. For healthy people, saturated fat should comprise no more than 7% of your total calories. On a 2,000 calorie-a-day diet, that’s about 140 calories worth of saturated fat. If you need to lower your LDL cholesterol, limit saturated fat to 5% to 6% of calories, or about 11 to 13 grams of saturated fat on a 2,000-calorie diet. Reduce trans fats to less than 1% of your total daily calories. This means avoiding fried foods and many junk foods.
When Should You Contact Your Healthcare Provider About Your Cholesterol Levels
In truth, your healthcare provider will probably talk to you about your numbers first. As always, contact your provider if you have any new or worsening pain or other uncomfortable feelings. Make sure you know what medications you take and what they are expected to do. Call the provider if you have a reaction to the medicine.
Before you go to the office, and after you have had a cholesterol test, it helps to have a list of questions prepared about your test results and any proposed treatment.
A note from Cleveland Clinic
When considering cholesterol numbers, its important to remember that you really have the ability to make those numbers go in your favor. What you choose to eat, how much you are able to move and how you deal with lifes ups and downs are things that you can influence.

How Is The Total Cholesterol Or Blood Cholesterol Test Done
A blood test is a routine test. A phlebotomist is a person whose job 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.
What Are The Normal Cholesterol Levels For Men And Women
A cholesterol test generally determines 4 distinct numbers: Total cholesterol, LDL, HDL, and triglycerides. Cholesterol being fat, it is not soluble in water. So it cannot circulate freely in the blood. But, the fact is that nature has devised a way to make water-soluble cholesterol, and transport it through the blood. This is by lipoproteins. The LDL or Low-density lipoprotein and the HDL or high-density lipoprotein are the 2 fundamental cholesterol carriers but to make things simpler, they are considered as cholesterol types. In addition, the lipid panel appraises the triglycerides . They have an impact on health in the same manners as cholesterol. At last, the total cholesterol is integrated as well in the results. Apart from these 4 general lipid levels, your doctor may want to access your very low-density lipoprotein or VLDL that is considered bad when high.

What Are Risk Factors For High Blood Cholesterol
Lifestyle, some health conditions, and family history can raise your risk for high cholesterol. Your doctor may suggest you have your cholesterol checked more often if you have risk factors, such as the following:
- A family history of heart disease or high blood cholesterol. You are more at risk of having high cholesterol if other people in your family have it. This may be due to genetics, but it may also be that families share the same unhealthy lifestyle habits. Some people also have a genetic condition called familial hypercholesterolemia, which can cause high levels of low-density lipoprotein , or bad, cholesterol from a young age.
- Diabetes. Type 2 diabetes raises bad cholesterol and lowers high-density lipoprotein , or good, cholesterol, raising the risk for heart disease and stroke.
- Older age. As you age, your body cant clear cholesterol as well as it used to.
- Being male. Men tend to have higher LDL and lower HDL cholesterol levels than women do. But after menopause , LDL cholesterol levels in women increase.4,5
- Having overweight or obesity. Excess weight, unhealthy eating habits, and lack of physical activity can lead to high cholesterol.
- Previously having had high cholesterol. If you have a history of high cholesterol, your doctor may want you to keep a closer watch on your cholesterol.
Your doctor may tell you not to eat or drink anything except water for 9 to 12 hours before the test.
Goals For Your Cholesterol Levels
It’s best to keep your total cholesterol level below 200. Women of any age should have an HDL level of 40 or higher.
If you already have heart disease or diabetes, or your doctor estimates that your 10-year risk of heart disease is 20 percent or higher, try to keep your LDL level below 100.
If you do not have heart disease or diabetes, but you have two major risk factors, try to keep your LDL cholesterol level below 130. Major risk factors are age over 55 cigarette smoking high blood pressure low HDL a father or brother with heart disease before age 55, or a mother or sister with heart disease before age 65.
If you have fewer than two major risk factors, try to keep your LDL level below 160.

What Should My Cholesterol Level Be At My Age
Cholesterol levels differ depending on age, weight, and gender. Because a personâs body produces more cholesterol with time, all adults should have their cholesterol levels checked on a regular basis, preferably every 4 to 6 years.
Cholesterol is classified into three types:
Cholesterol total
LDL, or âbad cholesterol,â
HDL, or âgood cholesterol,â
Most people struggle with balancing these levels. While total and LDL cholesterol levels should be kept low, having higher HDL cholesterol can give some protection against developing heart-related illnesses such as heart attacks and strokes.
