If your triglycerides are regularly from 240 to 300, that’s high. Usually, too many triglycerides mean you don’t eat well (like junk food all the time) and you don’t do exercise. But sometimes, it can come from your family. Rarely have symptoms but maybe sometimes hurt your stomach or give you pancreatitis. Eat the right things more, exercise, and don’t smoke or drink so much if you want lower levels.
