CONTENTS

This presentation is a brief knowledge about cholesterol its importance and its role in

our bodies along with respective diseases.

INTRODUCTION

A compound of the sterol type found in most body tissues, including the blood and the nerves. Cholesterol and its derivatives are important

constituents of cell membranes and precursors of other steroid

compounds

CHOLESTROL

Endogenous: Cholesterol is naturally found in our bodies. 75% of your body’s requirements are fulfilled by the endogenous cholesterol produced in the liver.

Exogenous: The cholesterol we get from food. Exogenous cholesterol is obtained from animal products, and this source of cholesterol accounts for about 25% of the body’s cholesterol needs.

OCCURENCE

Two types of cholesterol:

CLASSIFICATION OF CHOLESTROL

High Density Lipoproteins (HDL)

Low Density Lipoproteins (LDL)

“Good” Cholesterol High levels of HDL have been found to

lower risk of heart attack Risk of heart disease increases when

there are lower levels of HDL. “Help remove cholesterol from artery

walls and transport it to the liver for elimination from the body”

HDL

Bad cholesterol that can build up in the arteries.

High levels of LDL can increase risk of heart disease.

Composed mainly of cholesterol and a few proteins.

“Primarily responsible for depositing cholesterol within arteries”

LDL

Hypercholesterolemia Atherosclerosis Heart diseases

Cardiac attack/strokeDeath

BIOMEDICAL IMPORTANCE

Hypercholesterolemia is a condition characterized by very high levels of cholesterol in the blood.

HYPERCHOLESTEROLEMIA

Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body.

ATHEROSCLEROSIS

the blood carries oxygen to our heart, atherosclerosis reduces the amount of blood flowing to our heart. If blood stops flowing to the heart because of a blockage in the arteries, a heart attack occurs.

HEART DISEASES

When coronary artery of heart gets blocked by cholesterol deposition heart doesn’t get the blood supply it needs so cardiac attack occurs due to myocardial infarction.

CARDIAC ATTACK

Plaque buildup can also keep your brain from getting

enough blood and oxygen. If a clot completely blocks an artery feeding your brain,

you have a stroke.

STROKE

Grains (Fiber)• Any source of oatmeal, granola or nuts can be considered a form of fiber.

Oils (Fats)• Unsaturated fats used in moderation like: olive oil, canola oil or soybean oil

WHAT TO EAT???

Fruits•Any form of fruit or vegetable Oranges and raspberries

Meats Skinless poultry and lean meats
