🤔 What is Cholesterol?
Cholesterol is a waxy, fat-like substance found in every cell of your body. It's essential for building cell membranes, producing hormones (like testosterone and estrogen), and synthesizing vitamin D. However, too much cholesterol in your blood can lead to serious health problems.
Cholesterol travels through your bloodstream attached to lipoproteins. There are two main types:
- Low-Density Lipoprotein (LDL): "Bad" cholesterol — can build up in artery walls
- High-Density Lipoprotein (HDL): "Good" cholesterol — helps remove cholesterol from arteries
📊 Types of Cholesterol
🟥 LDL Cholesterol
"Bad" Cholesterol — can build up in artery walls.
- Main cause of plaque buildup
- Increases risk of heart attack
- Goal: < 100 mg/dL
🟩 HDL Cholesterol
"Good" Cholesterol — protects your heart.
- Removes excess cholesterol
- Protects against heart disease
- Goal: > 60 mg/dL
🟨 Triglycerides
Fat in your blood — another type of fat.
- Related to diet and lifestyle
- High levels increase heart risk
- Goal: < 150 mg/dL
🔵 Total Cholesterol
Combined measure — all cholesterol in your blood.
- Sum of LDL + HDL + 20% of triglycerides
- Goal: < 200 mg/dL
🔍 Causes & Risk Factors
Genetics
Familial hypercholesterolemia
Poor Diet
High saturated fats, trans fats
Obesity
BMI ≥ 30 increases risk
Physical Inactivity
Sedentary lifestyle
Smoking
Lowers HDL, damages arteries
Age
Risk increases with age
Diabetes
Affects cholesterol metabolism
Alcohol
Excessive consumption
🚨 Symptoms of High Cholesterol
⚠️ High cholesterol has NO symptoms — it's a "silent killer"!
In severe cases, cholesterol deposits can cause visible signs:
Xanthelasma
Yellowish deposits around the eyelids
Xanthomas
Yellowish, fatty deposits on tendons
Corneal Arcus
Grayish ring around the cornea
Chest Pain
If arteries are severely blocked
