cause of high blood fat

Causes

There are many types of cholesterol. The ones talked about most are:

• Total cholesterol - all the cholesterols combined
• High density lipoprotein (HDL) cholesterol - often called "good" cholesterol
• Low density lipoprotein (LDL) cholesterol - often called "bad" cholesterol

For many people, abnormal cholesterol levels are partly due to an unhealthy lifestyle. This often includes eating a diet that is high in fat. Other lifestyle factors are:

• Being overweight
• Lack of exercise

Some health conditions can also lead to abnormal cholesterol, including:

• Diabetes
• Kidney disease
• Polycystic ovary syndrome
• Pregnancy and other conditions that increase levels of female hormones
• Underactive thyroid gland

Medicines such as certain birth control pills, diuretics (water pills), beta-blockers, and some medicines used to treat depression may also raise cholesterol levels. Several disorders that are passed down through families lead to abnormal cholesterol and triglyceride levels. They include:

• Familial combined hyperlipidemia
• Familial dysbetalipoproteinemia
• Familial hypercholesterolemia
• Familial hypertriglyceridemia

Smoking does not cause higher cholesterol levels, but it can reduce your HDL ("good") cholesterol.
