Cholesterol Cholesterol Presentation Transcript

  • Cholesterol
  • What Is It? Hyperlipidemia is high cholesterol and triglycerides. Major adult cardiovascular diseases begin in childhood and adolescence.
  • What Is Cholesterol? Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells.
  • What Is Cholesterol? It's used to form cell membranes, some hormones and is needed for other functions.
  • What Is Cholesterol? But a high level of cholesterol in the blood is a major risk factor for coronary heart disease, which leads to heart attack.
  • What is LDL Cholesterol? Low-density lipoprotein is the major cholesterol carrier in the blood. If too much LDL cholesterol circulates in the blood, it can slowly build up in the walls of the arteries feeding the heart and brain. It can form plaque, a thick, hard deposit that can clog those arteries.
  • What is HDL Cholesterol? About 1/3 of blood cholesterol is carried by HDL. HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body.
  • What is HDL Cholesterol? HDL removes excess cholesterol from plaques and thus slows their growth. HDL cholesterol is known as "good" cholesterol because a high HDL level seems to protect against heart attack.
  • Where Do I Get Cholesterol? 2 Ways: The body produces varying amounts, usually about 1,000 milligrams a day. Foods also can contain cholesterol. Foods from animals (especially egg yolks, meat, poultry, shellfish and whole- and reduced-fat milk and dairy products) contain it.
  • Where Do I Get Cholesterol? Foods from plants (fruits, vegetables, grains, nuts and seeds) don't contain cholesterol. The body makes all the cholesterol it needs, so people don't need to consume it.
  • What Else Effects Cholesterol Levels? Tobacco smoke is one of the six major risk factors of heart disease that you can change or treat.
  • What Else Effects Cholesterol Levels? Smoking lowers HDL cholesterol levels and increases the tendency for blood to clot. Blood clots can cause heart attacks, stroke, and even death.
  • How Can I Lower My Cholesterol? Choose healthy fats (oils), limit saturated fat, and avoid trans fat. The total amount of fat you eat, whether high or low, isn't really linked with disease. What really matters is the type of fat you eat.
  • How Can I Lower My Cholesterol? The "bad" fats—saturated and trans fats— increase the risk for certain diseases. The "good" fats—monounsaturated and polyunsaturated fats—lower disease risk. Choosing foods without cholesterol and adding whole grains also helps.
  • Will Physical Activity Help? Regular physical activity increases HDL cholesterol in some people. A higher HDL cholesterol is linked with a lower risk of heart disease.
  • Will Physical Activity Help? Physical activity can also help control weight, diabetes and high blood pressure. Physical inactivity is a major risk factor for heart disease.
  • Where Should the Levels Be? Total Blood (or Serum) Cholesterol Level < 200 mg/dL Desirable 200–239 mg/dL Borderline-High Risk 240 mg/dL and over High Risk
  • Where Should the Levels Be? HDL (Good) Cholesterol Level 70 and above Optimal 60 to 70 Near Optimal < 40 mg/dL for men High Risk < 50 mg/dL for women High Risk
  • Where Should the Levels Be? LDL Cholesterol Levels < 100 mg/dL Optimal 100 to 129 mg/dL Near Optimal/ Above Optimal 130 to 159 mg/dL Borderline High 160 to 189 mg/dL High 190 mg/dL and above Very High
