Many of the factors that increase your risk of developing
high cholesterol are controllable.
Diabetes:Diabetes often leads to high
triglyceride levels, low
HDL levels, and high
LDL levels. However, effective management of diabetes
may help prevent these effects.
Diet: A diet high in
saturated fat,
cholesterol, and calories can increase your total
cholesterol level and lead to obesity. Too much saturated fat can stimulate the
production of cholesterol in your liver, which can increase production of LDL
and increase your risk of
coronary artery disease (CAD). Changing your diet may
lower your cholesterol.
Lack of physical activity: Lack of exercise
reduces HDL levels and increases obesity and insulin resistance in diabetes,
adding to these risk factors for high cholesterol. By increasing your blood
flow and promoting cardiovascular health, exercise benefits your entire
circulatory system and may lower your cholesterol.
Being overweight: Having excess body weight is
associated with decreased HDL levels and increased LDL levels. It also
contributes to glucose intolerance and the development of diabetes. Losing
weight to reach a healthy level may lower your cholesterol.
Smoking: Smoking increases your risk of
CAD, and quitting can reduce the risk.
The following table summarizes how each risk factor affects high
cholesterol through its effect on specific lipoproteins.
Controllable risk factors for high
cholesterolRisk factor | How does it affect your lipoprotein
levels? |
|---|
| Diabetes | - Decreases HDL ("good"
cholesterol)
- Increases triglycerides
|
| High-fat diet | - Increases LDL ("bad" cholesterol) and
triglycerides
|
| Lack of physical activity | |
| Being overweight | - May increase LDL and
triglycerides
- Decreases HDL
