What Happens If You Have High Cholesterol

Is High Cholesterol Dangerous?

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.

  • Narrowed arteries

    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

    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.

What Has The Biggest Impact On Ldl Cholesterol

Contrary to the long-held belief that dietary cholesterol itself is a major cause of high LDL, evidence suggests a weaker link. It’s still a good idea to steer clear of dietary cholesterol, but that intake isn’t the biggest influence. The current understanding is that the specific mix of carbohydrates and fats in your diet is the biggest factor in determining your LDL levels.

Heredity Can Play A Role

Some people inherit genes from their mother, father or even grandparents that cause them to have too much cholesterol. This is called familial hypercholesterolemia . The severity of FH is related to the duration and degree of LDL cholesterol in the blood. FH is dangerous because it can cause premature atherosclerotic heart disease.

If you have a family history of FH or problems related to high cholesterol, get your levels checked.

Cholesterol Levels For Adults

  • 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.

New Research Challenges Hypothesis

Research published this week in the British Medical Journal suggests otherwise. And according to researchers, provides rationale to reevaluate heart health guidelines.

The research team comprised of experts from seven different countries evaluated data collected from 19 studies on a total of 68,094 older adults. The team was seeking to determine if LDL cholesterol is associated with death in the older adults.

According to the cholesterol hypothesis, it should directly relate. According to the BMJ study, it doesnt.

Researchers say almost 80 percent of the participants in the studies who had high LDL cholesterol did not die because of their cholesterol level.

On the other hand, researchers discovered people with low levels of LDL cholesterol, or LDL-C, had the highest rates of death related to cardiovascular disease, the leading cause of death for both men and women in the United States.

These findings provide a paradoxical contradiction to the cholesterol hypothesis, researchers wrote. The cholesterol hypothesis predicts that LDL-C will be associated with increased all-cause and mortality.

Overall, the researchers four of whom have published books criticizing the cholesterol hypothesis say, the benefits from statin treatment have been exaggerated.

The Dangers Of High Cholesterol

High cholesterol is tough on arteries and your health. Here’s how to fight back.

When Ramona Richman’s older sister was diagnosed with high cholesterol, Richman wasn’t worried about her own risk. The San Francisco Bay Area stay-at-home mom had her weight under control and assumed that her diet was healthy. So when her doctor broke the news that she, too, had high cholesterol, she was shocked. Her reading of 269 mg/dL was well over the desirable level of less than 200 mg/dL. “My sister had high cholesterol and went on medication, so I imagine that it’s a genetic thing,” Richman, 48, says.

Genes can be a factor in high cholesterol, but so can being overweight, being physically inactive, and eating foods loaded with saturated fat and cholesterol. The liver manufactures all the cholesterol a body needs, but many people get substantial amounts from their diet. Regardless of the cause, high cholesterol poses dangers. It plays a major role in the development of atherosclerosis, or hardening and narrowing of the arteries, which in turn raises the risk of heart attack and stroke.

Does Age Make A Difference To Recommended Cholesterol Levels

Good and Bad Cholesterol

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.

Cholesterol And Heart Disease: Understanding The Connection

For years, it had been believed that theres more or less a straight line between cholesterol and heart disease but recent research suggests that this relationship may be more complex.

A Minneapolis Heart Foundation study, published in April 2017 in the Journal of the American Heart Association, found that many people who have heart attacks donthave high cholesterol. The link between cholesterol and heart disease is weak, says Dr. Roberts, who places a large portion of the blame for the persistence of that link on pharmaceutical advertising for statin drugs. Statins dolower cholesterol levels, she says, but atherosclerosis still progresses due to factors like age, poor diet, smoking, and so on.

In addition, a review of studies of cholesterol and cardiovascular disease published in August 2015 in the American Journal of Clinical Nutrition found that no rigorous connection could be drawn between dietary cholesterol intake and the risk of CVD.

In contrast, the results of long-term research, published in September 2017 in the journal Circulation, concluded that statin use in men with high LDL cholesterol who had no other risk factors for heart disease reduced their rates of coronary heart disease death, cardiovascular death, and all-cause mortality by 28 percent over 20 years.

Furthermore, a study of more than 400,000 people published in December 2019 in The Lancet found a strong link between non-HDL cholesterol and long-term risk of cardiovascular disease.

What Is High Ldl

Cholesterol itself is a necessary substance in the body. Its manufactured in your liver and it can be present in certain foods, especially meats, eggs, and dairy. LDL is a lipoproteina substance that conveys cholesterol to cells, aiding in maintaining cell structure, and serving as a precursor for substances vital to human function. Everyone has some amount of this lipoprotein, but problems arise when these are elevated.

When there is an excess of LDL, plaques build up in the arteries, causing atherosclerosis and reducing blood flow. When your hearts arteries are affected, insufficient oxygen levels damage cardiac muscles and cause CAD, angina , and even heart attack. Further, arteries in other parts of the body can also be affected, leading to peripheral artery disease and stroke.

Those who know they have a tendency to suffer symptoms from certain health problems are often concerned about it. Therefore, well focus on these below.

Cholesterol is a waxy substance present in the fats of the blood. Although many only know it for its harmful effects on health, in reality, its essential for the optimal functioning of our body.

What Can Affect My Ldl Level

The Dangers of High Cholesterol in Early Life â Nick Borja MD

Things that can affect your LDL level include

  • Diet. Saturated fat and cholesterol in the food you eat make your blood cholesterol level rise
  • Weight. Being overweight tends to raise your LDL level, lower your HDL level, and increase your total cholesterol level
  • Physical Activity. A lack of physical activity can lead to weight gain, which can raise your LDL level
  • Smoking.Cigarette smoking lowers your HDL cholesterol. Since HDL helps to remove LDL from your arteries, if you have less HDL, that can contribute to you having a higher LDL level.
  • Age and Sex. As women and men get older, their cholesterol levels rise. Before the age of menopause, women have lower total cholesterol levels than men of the same age. After the age of menopause, womens LDL levels tend to rise.
  • Genetics. Your genes partly determine how much cholesterol your body makes. High cholesterol can run in families. For example, familial hypercholesterolemia is an inherited form of high blood cholesterol.
  • Medicines. Certain medicines, including steroids, some blood pressure medicines, and HIV/AIDS medicines, can raise your LDL level.
  • Other medical conditions. Diseases such as chronic kidney disease, diabetes, and HIV/AIDS can cause a higher LDL level.
  • Race. Certain races may have an increased risk of high blood cholesterol. For example, African Americans typically have higher HDL and LDL cholesterol levels than whites.

Whats Your Cholesterol Level Anyway

A standard lipid blood test usually measures the concentration of total cholesterol, HDL cholesterol, and triglycerides levels. The LDL-cholesterol level is typically estimated from these numbers using a well-established formula that has been more recently revised and improved by researchers at Johns Hopkins.

So what are your target numbers? According to Michos, an ideal LDL cholesterol level should be less than 70 mg/dl, and a womans HDL cholesterol level ideally should be close to 50 mg/dl. Triglycerides should be less than 150 mg/dl. As Michos notes, total cholesterol levels well below 200 mg/dl are best.

Other Tips On High Cholesterol Foods

You may eliminate a bunch of high cholesterol foods and get onto a low cholesterol diet and stick with it religiously, only to sabotage yourself through things that you dont typically think of as food.

Drinking alcohol is a classic example of this. Many people tend to leave their alcohol consumption out of their diet tracking.

This is a mistake, especially if youre trying to restrict your cholesterol intake.

Once again moderation is key with things like alcohol.

Many studies have showed moderate alcohol consumption has a positive effect on cholesterol levels, but binge drinking and excessive consumption has the opposite effect and puts you at greater risk of a vast number of health problems.

Moderate consumption according to many experts is around one glass of wine per day, maximum.

With careful planning its relatively easy to significantly reduce the amount of cholesterol you take in, while still being able to enjoy your favorite high cholesterol foods in moderation.

What Makes Ldl Cholesterol Too High

High levels of ‘bad cholesterol’ more than double risk of strokes

A range of medical and lifestyle factors cause high LDL, including:

  • Diet: Diets high in saturated fats, salts, and cholesterol and low in healthy proteins and fiber can lead to high LDL.
  • Lack of physical activity: Not getting enough exercise and being sedentary contributes to weight gain and can also push levels up. You may see higher LDL if you dont get a minimum of 30 minutes a day of activity.
  • Weight status: Being overweight or obese greatly increases the chances of developing high LDL. Even modest gains in weight can push levels to unhealthy ranges.
  • Alcohol and tobacco: Smoking and drinking are both associated with high cholesterol, among many other detrimental effects on health.
  • Genetics: High LDL can be inherited, a condition called familial hypercholesterolemia . The severity of FH ranges, but those with the homozygous formin which both parents are carriers of the faulty genemay have extremely high amounts of this type of cholesterol.
  • Medications: Taking several classes of drugs can lead to spikes in LDL. These include those for heart disease, high blood pressure, inflammation, certain viruses, and seizures, among other conditions. Talk to your doctor about how these prescriptions may impact cholesterol.
  • Health conditions: Diseases and conditions that cause high LDL include type 2 diabetes, pregnancy, chronic kidney disease, and hypothyroidism.

Why Cholesterol Affects Women Differently

In general, women have higher levels of HDL cholesterol than men because the female sex hormone estrogen seems to boost this good cholesterol. But, like so much else, everything changes at menopause. At this point, many women experience a change in their cholesterol levels total and LDL cholesterol rise and HDL cholesterol falls. This is why women who had favorable cholesterol values during their childbearing years might end up with elevated cholesterol later in life. Of course, genetics and lifestyle factors can play big roles, too.

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.

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.
