including whether you are also diagnosed with cardiovascular disease.Ã Many health care providers recommend treating anyone with CVD with high-dose statin therapy. This includes those with coronary heart disease and who have had a stroke.

For those who do not have CVD, treatment is determined by your individual risk for developing heart disease. Ã That risk can be estimated using calculators which factor your age, sex, medical history, and other characteristics.Ã If your risk is high , your doctor may start you on treatment preventively. They generally keep in mind your preferences towards taking medication in generalFor those people whose risk is unclear, a coronary artery calcium score, which is a screening test looking for calcium in the arteries, can help determine the need for statins.

For both those who have CVD and those who do not, when the decision is made to start medication, the first choice is usually a statin.

Other special groups who may need treatment:

  • People with high triglyceride levels may benefit if they have other risk factors
  • People with diabetes: are at high risk, and a ldl under 100 is recommended for most
  • Older adults: a healthy, active older adult may benefit from the reduction you need, and be prescribed a medication accordingly.

For those without risk factors who have an LDL level at or above 190 mg/dl, the recommendation is to get this level down to below 100 mg/dl.

What Role does Cholesterol Play in a Healthy Body?

Cholesterol is also used in the formation of bile, a greenish fluid that is secreted by the liver and stored in the gallbladder. The body requires bile to break up foods that compose fatty substance. Bile performs as an emulsifier, it splits down sizeable globules of fat into smaller molecules so they can mix smoothly with the enzymes that digest fat. Once the fat is completely digested, bile helps the body to absorb it and acts a supportive end. The production of bile in the intestines is needed before cholesterol can be absorbed from nutritious foods. The body also require bile in order to absorb vitamins A, D, E, and K, the fat-soluble vitamins, derived from healthy nourishment.

What Are The Functions Of Cholesterol

Although cholesterol has a bad reputation, the body actually needs it. Here are some functions of cholesterol:

  • Helps in the formation and maintenance of cell membranes and structures.
  • Important for the making of many critical hormones like cortisol, testosterone, progesterone, and estrogen.
  • Used by the liver to make bile.
  • Nerve cells use cholesterol for insulation.
  • Also needed for the production of vitamin D.

Cholesterol: The Diagnosis To Eliminate:

The isolated finding of total hypercholesterolemia is not sufficient to affirm the chronic existence of this metabolic disorder. Some hypercholesterolemia is secondary:

  • The use of medication: cortisone, the pill, retinoids, antihypertensives, etc
  • To the existence of a disease: hypothyroidism.

In this case, it is sufficient to stop taking the medication responsible or to treat the hypothyroidism for the lipid metabolism disorder to disappear.

Other hypercholesterolemias are genetic and hereditary, and particularly difficult to treat.

It is also important to know that a meal very rich in fat can occasionally increase the cholesterol level. A return to a normal diet is then sufficient to normalize the blood cholesterol.

Functions Of Cholesterol In The Body

1. Producing Hormones

Cholesterol is essential for the bodys creation of steroid hormones. The steroid hormones most people are familiar with are sex hormones, such as testosterone, estrogen and progesterone. These hormones are needed for reproductive functioning and development of sex characteristics such as facial hair. Other types of steroid hormones related with cholesterol include cortisol and aldosterone. Cortisol is needed for blood sugar maintenance and infection prevention while aldosterone plays a part in water retention.

2. Creating Vitamin D

Vitamin D is important because it helps the bodys nervous system function properly. Vitamin D is also critical in other aspects, such as blood sugar regulation, mineral absorption, proper immune response, metabolism and reproduction. Humans can get vitamin D from multiple sources, including foods that are high in cholesterol, such as eggs and fish oil. Cholesterol also helps the body produce vitamin D from sunlight.

3. Aiding Digestion

One function of cholesterol in the body is better digestion. Without cholesterol, the body could not digest fat. When a person consumes food that contains fat, the gallbladder releases bile which breaks down large chunks of fat into much smaller particles that can be effectively digested by the body. Additionally, bile is needed for the body to properly absorb vitamins D, A, E and K. These vitamins are fat-soluble, so it makes sense that bile is required for proper use of vitamins.

Removes Ldl From Blood Vessels

One of the key benefits of having a healthy cholesterol balance is that bad cholesterol or any excess amounts of cholesterol are removed from the arteries by HDL and transported to the liver.

This removal is essential for the maintenance of healthy circulation, preventing conditions such as atherosclerosis, a narrowing of the blood vessels due to plaque build-up. This narrowing effect puts the body in danger of many potentially life-threatening conditions.

Health authorities recommend that cholesterol levels should be no higher than 5.5 mmol per litre if there are no other risk factors present. If there are other cardiovascular risk factors such as smoking and high blood pressure or pre-existing cardiovascular disease, then the aim for the LDL levels would be less than 2 mmol/l. Approximately half of all adult Australians have a blood cholesterol level above 5 mmol/l. This makes high blood cholesterol a major health concern in Australia.

Difference Between Good Cholesterol And Bad Cholesterol

When talking about cholesterol, two main types of cholesterol often comes up good cholesterol and bad cholesterol. High-density lipoprotein , which is good cholesterol and low-density lipoprotein , which is bad cholesterol. Cholesterol moves in the body with the help of lipoproteins .

HDL helps in getting rid of the cholesterol from the body. It transports it to the liver to be expelled out so that theres no excess cholesterol in the body and none of it gets collected in the arteries. And hence, HDL is called good cholesterol.

On the other hand, LDL takes cholesterol to your arteries. Too much cholesterol in arteries can lead to a buildup of plaque which can block your arteries in your heart and brain and you may suffer from a heart attack or stroke. Plaque buildup can also reduce the flow of oxygen to various organs which also becomes the cause for many diseases.

Vitamin D is processed in the liver and kidneys and is then circulated in the body for optimal physiological function.

A cause and effect relationship between cholesterol and vitamin D has been observed as a result of a study which showed that people with low levels of circulating vitamin D in the body tend to have high total cholesterol in the blood.
