Is High Lipoprotein A Dangerous
lipoproteinhighBelow are 10 natural ways to improve your cholesterol levels.
- The most common causes of high triglycerides are obesity and poorly controlled diabetes.
- Other causes of high triglycerides include hypothyroidism, kidney disease, and certain inherited lipid disorders.
- Estrogen therapy, which may be used for menopause symptoms, may also raise triglyceride levels.
What Factors Affect Cholesterol Levels
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.
What Does The Term Total Cholesterol Mean
The term total cholesterol refers to the total amount of the different kinds of cholesterol in your blood. One kind of cholesterol is the LDL cholesterol. Another kind is the HDL cholesterol. LDL stands for low-density lipoprotein. LDL is the bad cholesterol. HDL stands for high-density lipoprotein. HDL is the good cholesterol.

Why Is Cholesterol Important To Our Bodies
Every cell in the body needs cholesterol, which helps the cell membranes form the layers. These layers protect the contents of the cell by acting as the gatekeeper to what things can enter or leave the cell. It is made by the liver and is also used by the liver to make bile, which helps you digest foods. Cholesterol is also needed to make certain hormones and to produce vitamin D. Your liver makes enough cholesterol to meet your bodys needs for these important functions.
Ldl Cholesterol Or Bad Cholesterol
LDL cholesterol is often called bad cholesterol. It carries cholesterol to your arteries. If your levels of LDL cholesterol are too high, it can build up on the walls of your arteries.
This buildup is also known as cholesterol plaque. This plaque can narrow your arteries, limit your blood flow, and raise your risk of blood clots. If a blood clot blocks an artery in your heart or brain, it can cause a heart attack or stroke.

How Fat Moves From Food To The Bloodstream
Fat and cholesterol cant dissolve in water or blood. Instead, the body packages fat and cholesterol into tiny, protein-covered particles called lipoproteins. Lipoproteins can transport a lot of fat they mix easily with blood and flow with it. Some of these particles are big and fluffy, while others are small and dense. The most important ones are low-density lipoproteins , high-density lipoproteins , and triglycerides.
- Low Density lipoproteins
Low-density lipoproteins carry cholesterol from the liver to the rest of the body. Cells latch onto these particles and extract fat and cholesterol from them. When there is too much LDL cholesterol in the blood, these particles can form deposits in the walls of the coronary arteries and other arteries throughout the body. Such deposits, called plaque, can narrow arteries and limit blood flow. When plaque breaks apart, it can cause a heart attack or stroke. Because of this, LDL cholesterol is often referred to as bad, or harmful, cholesterol.
- High-density lipoproteins
High-density lipoproteins scavenge cholesterol from the bloodstream, from LDL, and from artery walls and ferry it back to the liver for disposal. Think of HDL as the garbage trucks of the bloodstream. HDL cholesterol is often referred to as good, or protective, cholesterol.
In general, the lower your LDL and the higher your HDL, the better your chances of preventing heart disease and other chronic conditions.
How Fat And Cholesterol In Food Affect Blood Cholesterol Levels
The types of fat in the diet help determine the amount of total, HDL, and LDL cholesterol in the bloodstream. The types and amount of carbohydrate in the diet also play a role. Cholesterol in food matters, too, but not nearly as much.
- The discovery half a century ago that high blood cholesterol levels were strongly associated with an increased risk for heart disease triggered numerous warnings to avoid foods that contain cholesterol, especially eggs and liver. However, scientific studies show a weak relationship between the amount of cholesterol a person consumes and his or her blood cholesterol levels
- In studies of more than 80,000 female nurses, Harvard researchers found that consuming about an egg a day was not associated with higher risk of heart disease. However, people who have heart disease or diabetes should monitor egg consumption.
For most people, the amount of cholesterol eaten has only a modest impact on the amount of cholesterol circulating in the blood. For some people, though, blood cholesterol levels rise and fall very strongly in relation to the amount of cholesterol eaten. For these responders, avoiding cholesterol-rich foods can have a substantial effect on blood cholesterol levels. Unfortunately, at this point there is no way other than by trial and error to identify responders from non-responders to dietary cholesterol.

What Affects My Cholesterol Levels
A variety of things can affect cholesterol levels. These are some things you can do to lower your cholesterol levels:
- Diet. Saturated fat and cholesterol in the food you eat make your blood cholesterol level rise. Saturated fat is the main problem, but cholesterol in foods also matters. Reducing the amount of saturated fat in your diet helps lower your blood cholesterol level. Foods that have high levels of saturated fats include some meats, dairy products, chocolate, baked goods, and deep-fried and processed foods.
- Weight. Being overweight is a risk factor for heart disease. It also tends to increase your cholesterol. Losing weight can help lower your LDL cholesterol, total cholesterol, and triglyceride levels. It also raises your HDL cholesterol level.
- Physical Activity. Not being physically active is a risk factor for heart disease. Regular physical activity can help lower LDL cholesterol and raise HDL cholesterol levels. It also helps you lose weight. You should try to be physically active for 30 minutes on most, if not all, days.
- Smoking.Cigarette smoking lowers your HDL cholesterol. HDL helps to remove bad cholesterol from your arteries. So a lower HDL can contribute to a higher level of bad cholesterol.
Things outside of your control that can also affect cholesterol levels include:
Which Foods Increase Ldl Cholesterol Levels
Your diet plays a massive role in determining your cholesterol levels. Foods high in trans fats, saturated fats, and salts can be especially dangerous. These include:
- Red meats
- Donuts, cookies, crackers, and other baked goods
- Fast foods
- Chicken with the skin on
- Cured or processed meats
Many food items you find in the store may have trans and saturated fats and high sodium, so make sure to carefully read the nutrition information before buying.

How Does This Ldl Calculator Work
This health tool computes the LDL cholesterol value from the total cholesterol, HDL, triglyceride levels according to the two formulas used in these cases: the Friedewald and Iranian study . The second formula is often recommended when the triglyceride levels are lower than average, as in the case of those with a low carbohydrate diet.
For your convenience, the LDL calculator allows you to enter the three values in either mg/dL or mmol/L . You will be given the two results in the corresponding measurement unit so that you can further on interpret the results easily.
In case of the 1st tab LDL in mg/dL these are the equations used:
The Friedewald formula: LDL = TC HDL TG / 5.0
The Iranian study formula: LDL = TC / 1.19 + TG / 1.9 HDL / 1.1 38
In case of the 2nd tab LDL in mmol/L these are the formulas behind the algorithm:
The Friedewald equation: LDL = TC HDL TG / 2.17
The Iranian study method: LDL = TC / 1.19 + TG / 0.81 HDL / 1.1 0.98

What Is Total Cholesterol
Total cholesterol can be determined in two ways. It can either be directly measured in the blood, or more commonly, it can also be calculated. The calculation takes into account the two main forms of cholesterol HDL and LDL as well as a small fraction of triglycerides. Any one of these three components can skew total cholesterol values. Here’s a brief definition of each:
HDL: High density lipoprotein is a protective form of cholesterol that helps to remove harmful particles from circulation before they can cause damage to blood vessels. This process earned it the nickname “good cholesterol.”
LDL: Low density lipoprotein is a potentially dangerous type of cholesterol that can become oxidized , which can lead to the hardening of arteries. If LDL builds up, it can lead to blockages which can cause serious cardiovascular incidents. LDL is therefore aptly referred to as the “bad cholesterol.”
Triglycerides: A form of stored fat that circulates in the bloodstream usually from excess weight, calories, alcohol, lack of exercise, liver damage, or genetics.

Abnormal Looking Toenails & Legs
If your legs and feet are not getting adequate blood flow the results may show in your toenails. Signs include thickening toenails or toenails that grow slower than normal.
Your skin may also change in appearance, becoming shiny and tight looking. If when you hold your leg up it appears white, but when you place it down it turns a purple/red color this indicates your body is diluting blood vessels in order to increase blood flow to your feet. Your feet may also turn pale or bluish when you sit for long periods because youre not getting proper blood circulation.
Dietary Tips To Avoid Cholesterol
The most important thing you can do to reduce your cholesterol level is to maintain a healthy lifestyle. You should try to:
- Increase the amount and variety of fresh fruit, vegetables and wholegrain foods you have each day.
- Choose low or reduced-fat milk, yoghurt and other dairy products or have added calcium soy drinks.
- Choose lean meat .
- Limit fatty meats, including sausages and salami, and choose leaner sandwich meats like turkey breast or cooked lean chicken.
- Have fish at least twice a week.
- Replace butter and dairy blends with polyunsaturated margarines.
- Include foods in your diet that are rich in soluble fibre and healthy fats, such as nuts, legumes and seeds.
- Limit cheese and ice cream to twice a week.
Other storage fats that are transported in blood lipoproteins include triglycerides. When present in high concentrations in the blood, this fat is also a risk for heart attack. Some foods will affect the cholesterol level or the triglyceride level and some will affect both.

What Happens If You Have High Cholesterol
What does high cholesterol mean?
High cholesterol means there is too much cholesterol in your blood. This can clog up your arteries the large blood vessels that carry blood around your body. Over time, this can lead to serious problems.
How does cholesterol clog up your arteries?
Excess cholesterol can be laid down in the walls of your arteries. Fatty areas known as plaques can form, and these become harder with time, making the arteries stiffer and narrower. This process is called atherosclerosis.
When the arteries become narrower, its harder for blood to flow through them. This puts a strain on your heart because it has to work harder to pump blood around your body. Eventually, the heart can become weak and cant work as well as it should.
Blood clots can form over the fatty, hardened parts of the arteries. The blood clots can block the artery completely, cutting off the blood flow. Bits of the blood clots can break away and become lodged in an artery or vein in another part of the body, which can cause a heart attack or stroke.
Effects Of High Cholesterol Levels
The liver is the main processing centre for cholesterol and dietary fat. When we eat animal fats, the liver transports the fat, together with cholesterol in the form of lipoproteins, into our bloodstream.
Too much cholesterol circulating within LDL in our bloodstream leads to fatty deposits developing in the arteries. This causes the vessels to narrow and they can eventually become blocked. This can lead to heart disease and stroke.

Who Should Be Tested
Your GP may recommend that you have your blood cholesterol levels tested if you:
- have been diagnosed with coronary heart disease, stroke or mini-stroke , or peripheral arterial disease
- are over the age of 40 people over 40 should have their estimate of CVD risk reviewed regularly
- have a family history of early cardiovascular disease for example, if your father or brother developed heart disease or had a heart attack or stroke before the age of 55, or if your mother or sister had these conditions before the age of 65
- have a close family member who has a cholesterol-related condition, such as familial hypercholesterolaemia
- are overweight or obese
- have high blood pressure or diabetes
- have another medical condition, such as kidney disease, an underactive thyroid, or an inflamed pancreas these conditions can cause increased levels of cholesterol or triglycerides

Good Vs Bad Cholesterol
Bad cholesterol, Low-density lipoproteins , can build up in your arteries and lead to health complications. Good cholesterol, high-density lipoproteins , returns your LDL cholesterol to the liver where the body can get rid of it. Your body needs a healthy balance of both good and bad cholesterol.
A diet high in fats increases LDL cholesterol in your blood. If LDL levels become too high or if you dont have enough HDL cholesterol to remove excess LDL, fatty deposits build up in your blood vessels. As a result, it makes it difficult for your body to pump adequate blood supply, creating potentially life-threatening problems impacting the heart or brain.
High cholesterol does not always cause symptoms in fact it typically begins with no symptoms at all. Thats why regular cholesterol screenings are so important regardless if you think you have high cholesterol or not.

How To Lower Cholesterol
If you have high cholesterol, your doctor may recommend lifestyle changes to help lower it. For instance, they may recommend changes to your diet, exercise habits, or other aspects of your daily routine. If you smoke, they will likely advise you to quit.
Your doctor may also prescribe medications or other treatments to help lower your cholesterol levels. In some cases, they may refer you to a specialist for more care.
Signs And Symptoms Of High Cholesterol
Typically, high cholesterol doesnt cause any symptoms until it causes a medical emergency, like a heart attack or stroke. These heart-disease-related events dont occur until high cholesterol levels have led to fatty plaque building up in the arteries. In turn, this leads to a narrowing of the arteries and a change in the makeup of the arterial lining, also known as heart disease.

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.
Can I Take The Test At Home
At-home cholesterol testing is available to measure calculated levels of LDL cholesterol. At-home testing for cholesterol uses a blood sample taken by a device that pricks your finger to obtain a small drop of blood that can be tested.
There are two types of at-home LDL tests that use a fingerstick blood sample:
- Self-tests: In this kind of test, the analysis of your blood happens at home. This can be done by applying a drop of blood on paper that is then placed into a small device that determines the cholesterol levels. Another type of self-test uses chemically treated paper that indicates the levels of cholesterol in your blood.
- Self-collection: For this kind of test, your blood sample is taken at home but is then sent to a laboratory for analysis.
For help deciding whether an at-home cholesterol test kit is right for you, it may be helpful to talk to your primary care doctor or cardiologist. It is common to have a follow-up cholesterol test performed by a doctor if an at-home cholesterol test kit finds abnormal results.

Cholesterol Levels For Men And Women
HDL levels differ for men and women
Women naturally have higher HDL cholesterol levels than men due to differences in the genes. Women should aim for an HDL cholesterol level above 1.2mmol/L while men should aim for above 1mmol/L.
Cholesterol levels can rise during pregnancy
During pregnancy, both cholesterol and triglyceride levels can significantly rise. We dont recommend getting a cholesterol test during pregnancy because your results wont be accurate. Our advice is to wait until at least 6-8 weeks after your baby is born or after you stop breastfeeding to get a cholesterol test. This means you dont need to worry unnecessarily. Find out more about pregnancy and blood fats.
