Cholesterol is one of the most familiar medical words today. Everyone knows “something” about it, but mostly cholesterol is associated in our minds with something “bad” and “undesirable” that occurs in older people.The facts and excess weight showed that about 20 percent of the U.S. population have cholesterol levels High blood.
Actually holesterol are substances, wax fatlike (lipid) that your body needs for vital functions, such as producing new cells, some hormones, vitamin D, and bile acids that help digest fats. It is present in the cell walls or membranes everywhere in the body, including brain, nerve, muscle, skin, liver, intestines, and heart.
Even our bodies need cholesterol to function normally, but too much cholesterol can be bad for our health. Why? Cholesterol and other fats can not dissolve in blood. They must be transported to and from the cells by special carriers. Cholesterol travels through your blood attached to proteins. Cholesterol-protein packages called lipoproteins. High density lipoprotein or low density depending on how much protein is in relation to fat.
Low-density lipoprotein (LDL) cholesterol is the major carrier in the blood. If too much LDL cholesterol circulates in the blood, it can slowly build up in artery walls to eat the heart and brain. Together with other substances can form plaque, deposits, thick hard that can clog those arteries. When coronary arteries are narrowed or clogged by cholesterol and fat (a process called atherosclerosis) and can not supply enough blood to the heart, the result is coronary heart disease. If the blood supply to part of the heart is really broken by total blockage of the coronary arteries, the result is a heart attack. This is usually due to a sudden closure from a blood clot that forms on the previous narrowing. Low-density lipoprotein cholesterol is called “bad” cholesterol because it can cause cholesterol buildup and blockage of your arteries. LDL mostly fat with only a small amount of protein.
Approximately one-third to one-fourth of blood cholesterol is carried by high-density lipoprotein (HDL). Medical experts think HDL tends to carry cholesterol away from arteries and back to the liver, where it passed from the body. Some experts believe HDL removes cholesterol from plaque excess and thus slowing their growth. HDL is called “good” cholesterol because it helps prevent cholesterol from building up in your arteries. It is mostly protein with only a small amount of fat.
Because there is good cholesterol and bad cholesterol is not only necessary to find out your cholesterol level, is also important to know your level of LDL and HDL.
The fact is that there are no symptoms of high cholesterol. Your first symptom of high cholesterol can be a heart attack or stroke. Cholesterol levels can be measured only by the blood test.The results come as the three main numbers:
Number of Cholesterol
LDL levels should be less than 160.
total cholesterol should be less than 200.
HDL levels should be more than 35.
Most Important: Your LDL level is a good indicator of the risk of heart disease. Lowering LDL is the main goal of treatment if you have high cholesterol. In general, the higher your LDL level, the greater your chances of developing heart disease.
Remember: regular cholesterol checks are encouraged to find out if your cholesterol levels within the normal range. WHAT CAN YOU DO ABOUT YOUR LDL CHOLESTEROL LEVEL? The main cause of high blood cholesterol is eating too much fat, especially saturated fat. Saturated fats found in animal products, such as meat, milk and other dairy products that are not free of fat, butter, and eggs. Some of these foods are also high in cholesterol. Fried fast foods and snack foods often have a lot of fat.
Being overweight and not exercising can make your bad cholesterol and increase your good cholesterol down. Regular physical activity can help lower LDL (bad cholesterol) and raise HDL (good) 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 damages blood vessel walls, making them likely to have cholesterol rich plaques rupture and have heart attacks. Smoking can also decrease HDL cholesterol levels as much as 15 percent.
Also, after women reach menopause, their bad cholesterol levels tend to rise. There is also a rare type of inherited high cholesterol that often leads to early heart disease.Some people inherit a condition called familial hypercholesterolemia, which means that very high cholesterol levels run in family.Other people, especially people that diabetes runs in families, inherit high triglyceride levels. Triglycerides are another type of blood fat that can also boost cholesterol levels. People with high blood triglycerides usually have lower HDL cholesterol and high risk of heart attacks and strokes. Progesterone, anabolic steroids and male sex hormones (testosterone) also lower HDL cholesterol levels.
So we can make the conclusion that the main therapy is to change your lifestyle. These include weight control, eating foods low in saturated fat and cholesterol, exercising regularly, not smoking and, in some cases, drinking less alcohol.
But, depending on your risk factors, if healthy eating and exercise do not work after about 6 months to 1 year, your doctor may suggest medicine to lower your cholesterol levels.
Now there is a very effective drug called “statins”, such as Lipitor.
This medicine works by helping to clear harmful low-density lipoprotein (LDL) cholesterol out of the blood and by limiting the body’s ability to form new LDL cholesterol. Each Lipitor Atorvastatin 20mg tablets included. It is in a class of drugs called HMG-CoA reductase inhibitors. It works by slowing the production of cholesterol in the body. Lipitor has demonstrated the ability to stop, not just slow, potentially fatal buildup of plaque in clogged arteries. While some drugs now available slow the buildup of new plaque, or atherosclerosis, in coronary arteries, there is no drug on the market has proven to be good to stop new build-up and clear existing plaque.
