Mixed hyperlipidemia is a condition in which high amounts of cholesterol and triglycerides are found in the blood, according to Alnylam Pharmaceuticals. The condition is inherited and can put individuals at higher risk for developing coronary artery disease.
When cholesterol disorders are inherited, the conditions tend to be harder to manage, according to MedlinePlus. In certain cases, low-fat diets and regular exercise may help to lower cholesterol and triglycerides naturally. Hyperlipidemia can also be treated with cholesterol-lowering medications if lifestyle changes are not enough to manage symptoms. However, treatment depends on the individual's age, weight and health history. Left untreated, high amounts of cholesterol in the blood can build up in the arteries, leading to complications such as stroke or heart disease.
