Your triglycerides are elevated because of a combination of genetics, diet and exercise parameters as well as alcohol intake. This increase is well documented to increase the risk of developing heart disease. First step is to cut down alcohol intake, or to switch to one with low carbohydrate load such as wine. Second to decrease your overall simple carbohydrate load. Third would be to engage in an aerobic exercise routine, fourth to stop cigarette cessation. Finally there are medications that decrease this level, but in the absence of following thee other measures medications alone are not sufficient and have not been show to decrease cardiovascular mortality.
