Explaining Cholesterol (Video)
Waxy, fat-like substance Naturally occurring in the body Some is needed for body to properly function protect nerves, make cell tissue, & make certain hormones Too much cholesterol can be dangerous!
Too much cholesterol in blood can stick to artery walls and build-up. Build-up is known as plaque. Plaque narrows and sometimes blocks arteries.
Bodies produce cholesterol needed for functions. Excess cholesterol comes from foods people eat: Animal sources- egg yolks, cheese, meat Foods with increased amounts of saturated and trans-fat
Factors affecting cholesterol : Heredity Physical Activity Weight Diet Age & Sex Lifestyle MMM, CHOLESTEROL!
Usually no symptoms for high cholesterol Should get tested: At 20 years old with follow up once every 5 years if levels are good About every year for people who have diabetes, high BP, heart disease, stroke, or blood flow problems Every year for those on medication controlling high cholesterol
Testing children is debatable. Only test children with high risk factors like: Family history of high cholesterol Family history of heart attacks at 55 in men and before age 65 in females
Lipoprotein Panel Test checks: Total Cholesterol HDL cholesterol LDL cholesterol Triglycerides Tests are done to get a better understanding of risks.
High Density Lipoprotein A.k.a. HDL Carries cholesterol from other parts of the body to the liver where it’s removed HDL
Low Density Lipoprotein A.k.a. LDL High levels of LDL lead to plaque build-up in arteries. LDL
Fat found in blood Increased amounts lead to risk of heart disease. What can raise triglyceride level? Obesity Lack of exercise Smoking cigarettes & drinking alcohol excessively Genetics, diseases, & medicine Poor diet with large amounts of carbohydrates and fats
Levels of cholesterol depend on the individual. Normal levels vary but typically: Total Cholesterol: less than 200 mg/dL is desired HDL: 40-59 mg/dL is good, lower than 40 is putting yourself at risk LDL: less than 100 mg/dL is optimal Triglycerides: 150-199 mg/dL is borderline high
High Cholesterol can lead to: Atherosclerosis Coronary Heart Disease Heart Attack Stroke High Blood Pressure
Medicine Statins Bile acid sequestrants Nicotinic acid Fibrates Ezitimibe All used to lower LDL or raise HDL Muscle cramping is a serious side effect of some medicines. Some may also cause liver problems.
