Cholesterol is a soft, fat-like, waxy substance found in the bloodstream and in all your body's cells. It's normal to have cholesterol. It's an important part of a healthy body because it's used for producing cell membranes and some hormones, and serves other needed bodily functions. But too high a level of cholesterol in the blood is a major risk for coronary heart disease, which leads to heart attack. It's also a risk factor for stroke. Hypercholesterolemia is the term for high levels of blood cholesterol.
You get cholesterol in two ways. Your body makes some of it, and the rest comes from cholesterol in animal products that you eat, such as meats, poultry, fish, eggs, butter, cheese and whole milk. Food from plants — like fruits, vegetables and cereals — doesn't have cholesterol. Some foods that don't contain animal products may contain trans-fats, which cause your body to make more cholesterol. Foods with saturated fats also cause the body to make more cholesterol.
Cholesterol and other fats can't dissolve in the blood. They have to be transported to and from the cells by special carriers called lipoproteins. There are two kinds that you need to know about. Low-density lipoprotein, or LDL, is known as the "bad" cholesterol. Too much LDL cholesterol can clog your arteries, increasing your risk of heart attack and stroke. High-density lipoprotein, or HDL, is known as the "good" cholesterol. Your body makes HDL cholesterol for your protection. It carries cholesterol away from your arteries. Studies suggest that high levels of HDL cholesterol reduce your risk of heart attack.
What's the Difference Between LDL and HDL Cholesterol?
Why LDL cholesterol is considered "bad"?
When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances it can form plaque, a thick, hard deposit that can clog those arteries. This condition is known as atherosclerosis. If a clot forms and blocks a narrowed artery, it can cause a heart attack or stroke. The levels of HDL cholesterol and LDL cholesterol in the blood are measured to evaluate the risk of having a heart attack. LDL cholesterol of less than 100 mg/dL is the optimal level. Less than 130 mg/dL is near optimal for most people. A high LDL...

...ce the risk of coronary heart disease as people whose cholesterol level is below 200 mg/dL. Half of all Americans age 20 and older have cholesterol levels that are too high (200 mg/dL or higher). The good news is you can make many lifestyle changes to lower your cholesterol and reduce your risk of heart disease and stroke.
To reduce cholesterol in your blood, eat foods low in saturated fat and cholesterol, lose weight if you need to and exercise for a total of at least 30 minutes on most or all days of the week. Some people may also need to take medicine, because changing their diet isn't enough. If you've been prescribed medication or advised to make lifestyle changes to help manage your cholesterol, carefully follow your doctor's recommendations.
Learn the facts about cholesterol have regular screenings and, if you need to lower your cholesterol level, work with your healthcare professionals to set up a plan. Reduce your risk of heart attack — take responsibility for managing your cholesterol levels. By lowering your blood cholesterol level, you'll cut your risk for heart disease, heart attack and stroke!

Hyperlipidemia or increased cholesterol builds up causing narrowing in the arteries, which reduces oxygen rich blood flow to the heart and tissues, also increasing the risk for myocardial infarction. Obesity increases the risk of developing diabetes, high blood pressure, and hyperlipidemia, increasing the risk of atherosclerosis, and therefore increasing
LDL or bad cholesterol comes from food that is a high source of cholesterol and/or saturated fats. Plaque forms when bad or LDL cholesterol builds up in your bloodstream and attaches to the arterial wall, as more LDL builds up the plaque becomes larger, this can become a major problem for your cardiovascular system. Because plaque is a substance that has rough edges, it reduces the elastic nature of the artery which means your heart will have to work double-time to pump the necessary blood to all your limbs, that will mean your limbs won’t get the amount of oxygen that they require to function properly. Plaque can also narrow the area blood has to pass through, this means your heart has to work overtime and overall capacity of your cardiovascular system is lowered. When the LDL cholesterol embeds itself in the wall of the artery it than damages the artery then blood pressure expands it which causes an aneurysm. When an aneurysm is too weak there is a high possibility of it bursting, when that happens it leaves the cells in and around that area without oxygen. If that artery is connected to a major vital organ the person will most likely die. When the blood flow is slowed it shows a greater risk for blood clots and although blood clots are natural and important to healing broken blood vessels, if blood clots gather inside the blood vessel this proves to be a serious health risk. The clots have the possibility to get stuck and completely cut off the blood flow to cells, leaving them without oxygen and causing them to die. If a clot gets inside a blood vessel connected to a major organ this could cause the person to die. The heart is fed by the coronary artery, if plaque or a blood clot blocks off blood flow to the heart, the heart ...
Hypercholesterolemia is the presence of high levels of cholesterol in the blood. Cholesterol is a waxy fat-like substance and is a major class of lipid, so it gets into the blood by lipoproteins [1]. A high level of lipoproteins is unhealthy. A high level can result in an elevated risk of atherosclerosis and coronary heart disease [2]. The high levels of lipoproteins are often influenced by a combination of genetic and environmental factors such as obesity or dieting habits [2]. High cholesterol can be caused by mutations in the following genes: APOB, LDLR, LDLRAP1, and PCSK9 [3]. Mutations in the LDLR gene are responsible for causing familial hypercholesterolemia, which is the most commonly seen form of inherited high cholesterol [3]. The LDLR gene contains instructions for making LDL receptors or low-density lipoprotein receptors. LDL receptors play critical roles in regulating levels of cholesterol in the blood by removing low-density lipoproteins from the bloodstream. Mutations in the LDLR gene can make the amount of LDL receptors produced less than normal or affect their job of removing the low-density lipoproteins in the blood [4]. People who have these mutations will have higher levels of cholesterol. There are many ways that the environment can affect the levels of cholesterol in the blood. Reducing the amount of dietary fat you consume lowers the total amount of cholesterol in the blood [5]. Sucrose and fructose can raise the amount of LDL in the blood. Reducing fatty foods will however lower the amount of LDL [5]. Having a healthy body and maintaining physical exercise plays a key role in keeping your cholesterol at a healthy level. If you are overweight or obese you can lower your cholesterol levels by simply losing ...
CAD is a leading cause of morbidity and mortality throughout the worldwide. The prevalence of biological and metabolic risk factors were also found to be high in development of coronary artery disease. Patients with hypercholesterolemia are at increased risk to experience cardiovascular events and to die from vascular disease [2]. .Statins, among the most commonly prescribed drugs worldwide, are cholesterol let downing agents used to manage cardiovascular and coronary heart diseases and to treat hypercholesterolemia. Statin’s therapy ...
Blood pressure tends to rise with age. Following a healthy lifestyle helps delay or prevent this rise in blood pressure. People who have HBP can take steps to control it and reduce their risk for related health problems. Key steps include following a healthy lifestyle, exercise most days of the week, avoid alcohol, stop smoking, and having ongoing medical care.
The data presented in this table supports the conclusion of Purdy et al. (2005) that the inclusion of cholesterol to the CHO cell membranes will result in significant changes to the membrane, confirming the established function of cholesterol as a regulator of membrane fluidity.
Some ways to fight of this syndrome include regular diet and exercise and various bariatric surgeries. Long range BMI target/goal is less than 25. If life style change is not enough than drugs that help lower cholesterol level high blood pressure and blood sugar can be used such as statins, fibrates or nicotinic acid. 4Other things that can be done include trying to fight the insulin resistance by starting thiazolidinediones. Also, treating the different risk factors like elevated blood pressure, prothrombotic and proinflammatory state independently.
There are preventive measures that can be taken to prevent coronary heart disease. Go to the doctor and get a regularly routine checkup. Mainly have a healthy lifestyle by having a healthy diet; this diet should include a low salt intake, whole grain foods, low fat/ fat free diary, meats (lean), fruits , vegetables, nuts, and water. Also physical activities or being active decrease the chances of getting CHD.
It can be prevented naturally by practicing vegetarianism which refers to those who practice a diet low in meat and fish or may not consume meat products at all. Vegetarianism diet offers an advantage because people who practice or change their lifestyle to no meat consumption have lower body mass index (BMI), and can reverse the effects of atherosclerosis. (reducing, 2010). However, people have to be careful while practicing it because a poorly vegetarian diet can cause anemia, fatigue, decreased zinc, decreased vitamin C. Also it can decrease B12 and this may cause neural tube defects, congenital heart defects, dementia, and Alzheimer’s disease. It is very important to educate vegetarians to have a vitamin B supplementation to prevent another type of conditions. (reducing, 2010). There is another way to prevent or reverse heart disease by consuming seven heart nutrients which are fiber, fish oil, magnesium, vitamin D, vitamin K, zinc, and COQ10. Also, there are statin drugs such as Crestor (rosuvastatin) and Lipitor (atorvastatin) that are being prescribe to cholesterol-lowering but there is a concern about their safety and effectiveness. There is an alternative to these types of drugs. The statin alternatives are Niacin (B3) known to be effective in lowering blood cholesterol and triglyceride levels, and citrus flavones that work blocking the enzymes in the liver
When one or several lipids combine with proteins this forms lipoproteins, these transport fat throughout the bloodstream. High-density lipoproteins, also known as HDL, carry fat away from body cells, therefore preventing its growth in the artery walls. Low-Density Lipoproteins, also known as LDL, contain a high amount of cholesterol and seem to help the build up of fatty materials in the artery walls. The situation that you should go for would be high HDL and low LDL levels. Your goal should be to keep your overall cholesterol at below 200, with LDL lower than 40, and your HDL should be at around 160. This will lower the risk of heart disease and other related problems with cholesterol.
My DRI of cholesterol was maxed at 300mg and my intake was 267mg. Still relatively high so could start consuming Oatmeal for breakfast in which reduces your low-density lipoprotein (LDL), the "bad" cholesterol. Also, I...
Six moths ago I scheduled a physical and blood work, a month later I was diagnosed with high cholesterol. My total cholesterol levels were at 250, with and LDL of 150, which puts me at a higher risk of cardiovascular illness. I was given the option of changing my eating habits with a combination of exercise to manage and lower my cholesterol levels, thus avoiding the need for medication. The dr. was very supportive, he had many helpful suggestions and showed me several ways in which I could lower my cholesterol by making simple food choices. After a long discussion I decided this was the way to go, I hate taking medication. When I reviewed the analysis report and saw that my cholesterol continues to be above the recommended range I let out a huge sigh, it took a few seconds to compose myself before I continued to look over it. This whole time I thought I had maintained my cholesterol under control, the analysis report proved that I was wrong. It is important that I make changes on how I eat. High cholesterol is indicative of cardiovascular illnesses that possibly result in serious chronic diseases. Diseases that are linked to high cholesterol are Coronary heart disease, peripheral vascular disease, diabetes and high blood pressure. The main risk from cholesterol is heart attacks. If the cholesterol remains high, it can build up overtime in the walls of the arteries forming a build up known as plaque. This plaque will cause the arteries
• Exercise regularly. Ask your health care provider what kinds of exercise are best for you.
Saturated fat and cholesterol and an increased risk of heart disease. Fiber and a reduced risk of cancer. Fruit, vegetables and grain products that contain fiber and a reduced risk of heart disease.
Saturated fats come from animal sources like steak, hamburger and pork. Unsaturated fats are derived from plants. There are also trans fats that are considered poison for the body. They raise the bad cholesterol in your body, and should never be included in a healthy diet. There are also fatty acids like omega-3 and omega-6 that are good for a healthy body.
