Study Notes
Cholesterol Overview
- Cholesterol is a waxy substance found in all cells of the body.
- It's important for healthy cell function.
- The body makes cholesterol, but it also comes from food.
- High levels of cholesterol can lead to serious health problems.
Types of Cholesterol
- There are two main types: low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
- LDL ("bad" cholesterol) builds up in arteries, forming plaques.
- HDL ("good" cholesterol) helps remove excess cholesterol from the body.
Cholesterol Digestion and Absorption
- Cholesterol is ingested in food, and the body absorbs and uses it.
- Some cholesterol is made in the liver.
- Excess cholesterol is eliminated.
Cholesterol in the Arteries
- High LDL levels can lead to plaque buildup in arteries.
- This buildup can narrow arteries, reducing blood flow.
- This process can cause severe health issues.
Cholesterol Levels and Risk Factors
- Optimal total cholesterol is less than 200 mg/dL.
- Near optimal total cholesterol is 200-239 mg/dL.
- Borderline high total cholesterol is 240-259 mg/dL.
- High total cholesterol is 260 mg/dL or higher.
- The provided chart shows specific cholesterol levels and their associated risks.
Cholesterol and Related Health Concerns
- High cholesterol can lead to various complications like angina, heart attack, stroke.
- High blood cholesterol levels should be managed and controlled.
Healthy Cholesterol Habits
