Factors that contribute to developing high triglyceride levels include obesity, improperly managed diabetes, kidney disease, an underactive thyroid and regularly eating more calories than an individual uses, according to WebMD. Some medicines may also raise one's triglyceride level and the condition may also be genetic.
Triglycerides are a type of fat that the body uses for energy, states WebMD. All people need some triglycerides to maintain proper health. But having too much in an individual's body can raise the chance of developing heart disease. High triglycerides may also be a sign of a condition known as metabolic syndrome. Metabolic syndrome is a combination of several conditions, such as too much fat around the waist, low HDL levels and high blood pressure and blood sugar. Having this condition not only increases an individual's risk of heart disease, but diabetes and stroke as well. In most cases, high triglycerides cause no symptoms, states WebMD. However, if the condition is genetic, an individual may see fatty deposits, called xanthomas, underneath her skin.
Treatment usually involves losing weight and maintaining a healthy weight, according to WebMD. Limiting the amount of fat an individual eats as well as being more active can also help lower triglyceride levels. People who have high triglycerides should also limit the amount of sugar they eat and if they smoke or drink, they should quit smoking entirely and limit their alcohol intake.
