What Makes Ldl Cholesterol Too High
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 don’t 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.
What To Do If You Have High Cholesterol
For people with high cholesterol, lifestyle changes are necessary. Raby says to focus on eating healthy, exercising, managing stress, and quitting tobacco.
In addition to diet and exercise, physicians most commonly prescribe statin drugs, which slow down cholesterol production in the liver and increase cholesterol removal from the blood. Talk to your doctor about this possibility if people in your family have had heart attacks, or required stents or before age 55.
Is Dietary Cholesterol Harmful
Research has shown that dietary cholesterol does not significantly impact cholesterol levels in your body, and data from population studies does not support an association between dietary cholesterol and heart disease in the general population .
Though dietary cholesterol can slightly impact cholesterol levels, this isnt an issue for most people.
In fact, two-thirds of the worlds population experience little or no increase in cholesterol levels after eating cholesterol-rich foods even in large amounts .
A small number of people are considered cholesterol non-compensators or hyper-responders and appear to be more vulnerable to high-cholesterol foods.
However, hyper-responders are thought to recycle extra cholesterol back to the liver for excretion .
Dietary cholesterol has also been shown to beneficially affect the LDL-to-HDL ratio, which is considered the best indicator of heart disease risk .
While research shows that its unnecessary for most people to avoid dietary cholesterol, keep in mind that not all cholesterol-containing foods are healthy.
Here are 7 healthy high-cholesterol foods and 4 to avoid.

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.
Good Vs Bad Cholesterol
Cholesterol travels through your bloodstream in small packages called lipoproteins, which are made up of fat on the inside and proteins on the outside. Because fats arent water-soluble, this binding with proteins helps move them through the bloodstream.
Its important to have healthy levels of two lipoproteins that carry cholesterol throughout the body: low-density lipoproteins and high-density lipoproteins . Both LDLs and HDLs transport cholesterol in and out of cells and are involved in damage control of cells and tissues.
LDLs carry 75 percent of the cholesterol in our bodies and are the cholesterol compounds most involved in cell damage and tissue repair and protection. HDLs do only 25 percent of the work they transport cholesterol to and from the liver and serve as the bodys cholesterol-recycling system.
LDL is called bad cholesterol because when your levels of LDL are high, this can lead to a buildup of cholesterol in your arteries. When you have high levels of LDL cholesterol in your blood, you have a greater chance of developing heart disease. LDL cholesterol also raises your risk for a condition called peripheral artery disease, which can develop when plaque buildup narrows an artery supplying blood to the legs.
Conversely, HDL cholesterol is known as good cholesterol because it can carry cholesterol from other parts of your body back to your liver, where its properly broken down and removed from your body.

Causes Of High Cholesterol
Eating too many foods that are high in cholesterol, saturated fats, and trans fats may increase your risk of developing high cholesterol. Living with obesity can also increase your risk. Other lifestyle factors that can contribute to high cholesterol include inactivity and smoking.
Your genetics can also affect your chances of developing high cholesterol. Genes are passed down from parents to children. Certain genes instruct your body on how to process cholesterol and fats. If your parents have high cholesterol, you may be at a greater risk of having it too.
In rare cases, high cholesterol is caused by familial hypercholesterolemia. This genetic disorder prevents your body from removing LDL. According to the National Human Genome Research Institute , most adults with this condition have total cholesterol levels above 300 milligrams per deciliter and LDL levels above 200 milligrams per deciliter.
Other health conditions, such as diabetes and hypothyroidism, may also increase your risk of developing high cholesterol and related complications.
Kidney Disease & Cholesterol Association
The clinical study reveals high triglyceride has an association with increased creatinine level. Additionally, it indicates a decrease in kidney function.
Low HDL cholesterol has associated with greater risk. But, total and LDL cholesterol is not associated with the risk of chronic kidney disease. Elevated levels of creatinine in the blood indicate a decline in the kidney function. The increase of 0.4 milligrams of creatinine/deciliter of blood indicates a decrease in kidney function.

What Causes High Cholesterol
Many factors can increase your chances of having heart problems or a stroke if you have high cholesterol.
These include:
- an unhealthy diet in particular, eating high levels of saturated fat
- smoking a chemical called acrolin, found in cigarettes, stops HDL transporting cholesterol from fatty deposits to the liver, leading to narrowing of the arteries
- having diabetes or high blood pressure
- having a family history of stroke or heart disease
There’s also an inherited condition called familial hypercholesterolaemia. This can cause high cholesterol even in someone who eats healthily.

Increase Your Physical Activity
Physical activity increases levels of HDL cholesterol the good cholesterol that removes LDL cholesterol from the blood. Vigorous aerobic exercise is best.
If you havent been exercising much lately, gradually build up to the recommended amount of physical activity:
- People aged 18-64 years should do 30 to 60 minutes of moderate-intensity physical activity on most days of the week.
- People aged 65 years and over should aim for a total of 30 minutes of moderate physical activity on most days .
Moderate-intensity exercise is a level that increases your heart rate and breathing but allows you to keep talking. Vigorous intensity exercise makes your heart rate higher and makes you breathe more heavily.
Resistance training and muscle-toning exercises can increase HDL cholesterol. Aim to do this twice a week.
What Can Raise My Risk Of High Cholesterol
A variety of things can raise your risk for high cholesterol:
- Age. Your cholesterol levels tend to rise as you get older. Even though it is less common, younger people, including children and teens, can also have high cholesterol.
- Heredity. High blood cholesterol can run in families.
- Weight. Being overweight or having obesity raises your cholesterol level.
- Race. Certain races may have an increased risk of high cholesterol. For example, African Americans typically have higher HDL and LDL cholesterol levels than whites.

Is High Ldl Cholesterol Really Symptomless
Doctors find that high cholesterol is often difficult to diagnose, especially in young people as there are usually no really symptoms to alert the individual to a problem.
There are a couple of symptoms people may notice, but again these are not common.
- Pain Although fairly rare, it is possible for people with high cholesterol to experience pain in their legs and arms. This is usually due to a build up of cholesterol in the blood, which is then causing a problem in the arteries.
- Chest pain Again, as a result of a build up of cholesterol in the arteries, individuals with high cholesterol may find they experience pain their chest, also called angina pectoris. If you do experience pain in your chest area, you should seek advice from a doctor immediately. Do not assume it is a result of high LDL cholesterol.
- Heart Problems In cases of extremely high LDL cholesterol, there is the risk that the individual will suffer from severe heart palpitations. This, coupled with hardening of the arteries can lead to heart attacks and even death.
- Skin problems In a small number of cases, high LDL levels can cause changes in a persons complexion with small fatty pockets forming on the skin.
If you have any concerns about your cholesterol level, regardless of whether you have suffered from any symptoms or not, you can consult with your doctor who will organize the appropriate tests.
What Is Cholesterol Used For
- It helps create a healthy outer wall for cells around your body.
- It helps with the creation of hormones and vitamin D. So, it has an important role in keeping your bones, teeth and muscles healthy.
To perform these essential functions, the liver produces most of the cholesterol you need.
So, what happens if you end up with more of the fatty substance in your bloodstream than you need? This is referred to as high cholesterol and it can in time cause you problems. Excess cholesterol can start to build up and stick to the walls of your arteries. This makes your blood vessels get stiffer and narrower. Because itâs more difficult for blood to flow freely around your body, if cholesterol continues to accumulate, it can increase your risk of a heart attack or stroke.

Checking Your Blood Cholesterol Level
A cholesterol screening is an overall look at the fats in your blood. Screenings help identify your risk for heart disease. It is important to have what is called a full lipid profile to show the actual levels of each type of fat in your blood: LDL, HDL, triglycerides, and others. Talk with your healthcare provider about when to have this test.
Recent Guidelines For Normal Cholesterol Levels
Your body needs some cholesterol to function properly, including some LDL. But if your LDL levels are too high, it can raise your risk of serious health problems.
In 2013, the American College of Cardiologists and the American Heart Association developed new guidelines for the treatment of high cholesterol.
Before this change, doctors would manage cholesterol based on numbers in a cholesterol levels chart. Your doctor would measure your total cholesterol, HDL cholesterol, and LDL cholesterol levels. They would then decide whether to prescribe a cholesterol-lowering medication based on how your numbers compared to the numbers in the chart.
Under the new guidelines, in addition to your cholesterol levels, treatment recommendations consider other risk factors for heart disease. These risk factors include diabetes and the estimated 10-year risk for a cardiac event such as a heart attack or stroke. So what your normal cholesterol levels are depends on whether you have other risk factors for heart disease.
These new guidelines recommend that if you dont have risk factors for heart disease, your doctor should prescribe treatment if your LDL is greater than 189 mg/dL. To find out what your personal cholesterol recommendations are, talk to your doctor.
With the changes mentioned above in the treatment guidelines for high cholesterol, cholesterol charts are no longer considered the best way for doctors to gauge the management of cholesterol levels in adults.
