High Cholesterol

High Cholesterol & Diet

High cholesterol (hyperlipidemia) is a condition where there are increased levels of fats (lipids) in the blood. These include low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. Excess cholesterol can build up in blood vessels and increase the risk of heart disease.

Types of Cholesterol

LDL (Bad Cholesterol): Can block arteries
HDL (Good Cholesterol): Helps remove excess cholesterol
Triglycerides: Another type of fat linked to heart risk
Total Cholesterol: Overall level in the blood

Clinical Features

Most people have no symptoms. In some cases:

Fatigue
Chest discomfort (late stage)
Fat deposits on skin (xanthomas, rare)

When to Get Tested

Age above 35 years
Family history of diabetes
Overweight or inactive lifestyle
High blood pressure or cholesterol

Regular screening helps early diagnosis.

When to Check Cholesterol

Age above 30 years
Diabetes or hypertension
Overweight or sedentary lifestyle
Family history of heart disease
Smoking
Regular screening is essential as the condition is usually silent.

Brief History (Development)

High cholesterol develops gradually due to poor diet, lack of exercise, genetic factors, and associated conditions like diabetes. Over time, it leads to plaque formation in arteries.

Management Plan

Lifestyle Changes: Healthy diet, reduced saturated fats, exercise
Medications: Statins or other lipid-lowering drugs if required
Weight Control: Essential for long-term management
Regular Follow-up

Complications

Heart disease
Stroke
Peripheral artery disease

Monitoring

Lipid profile every 6–12 months
Blood sugar and blood pressure
Risk assessment based on comorbidities

Cholesterol Levels (Normal & Targets)

Type	Normal Level	Target (General)	Target (Diabetes/Heart Disease)
Total Cholesterol	<200 mg/dL	<200	<180
LDL (Bad)	<100 mg/dL	<100	<70 (or <55 high risk)
HDL (Good)	>40 (men), >50 (women)	Higher is better	Higher is better
Triglycerides	<150 mg/dL	<150	<150

Future and Advancements

Personalized lipid management
New injectable therapies (PCSK9 inhibitors)
Better risk prediction tools
Integration with diabetes and heart care programs
