While the body uses some triglycerides for energy, a person should lower high triglyceride levels, as this may contribute to heart disease and signal metabolic syndrome, states WebMD. Metabolic syndrome occurs when a person has high blood pressure, high blood sugar, a low level of good cholesterol, too much fat around the waist and high triglyceride levels.
Typically, high triglyceride levels are caused by other conditions such as obesity, kidney disease, an underactive thyroid or diabetes not kept in check, according to WebMD. Additionally, people who consume more calories than are burned on a regular basis and people who drink excessively can have high triglyceride levels. Some types of medication can also cause higher than normal triglyceride levels including steroids, beta blockers, estrogen and diuretics. Less commonly, high triglyceride levels can also be caused by genetics.
A normal triglyceride range is less than 150, while a borderline-high level is 150 to 199, states WebMD. Anything from 200 to 499 is considered a high level, while 500 and over is considered very high. A person with a high triglyceride level can achieve a lower level by being more active, limiting drinking, quitting smoking, and limiting fats and sugars in the diet. Losing weight and staying at a healthy weight are also beneficial in reducing high triglyceride levels.
