Having high triglycerides means a person is much more likely to develop metabolic syndrome, which is a group of conditions that include high blood pressure, high blood sugar and abnormal cholesterol levels, explains Mayo Clinic. High triglycerides also increase a person's chance of developing kidney disease and atherosclerosis.
Atherosclerosis is a condition in which the walls of a person's arteries harden or thicken, states Mayo Clinic. People with this condition have an increased chance of developing not only a stroke and heart disease but also a heart attack. High triglycerides could also mean a person has kidney or liver disease or a low level of thyroid hormone in the body. In some people, high triglycerides may be a sign of a rare genetic condition or a side effect of a person's medicine. Some birth control pills, diuretics, beta blockers and the breast cancer drug tamoxifen could possibly raise triglyceride levels.
The best way to lower triglycerides is to live a more healthy lifestyle, according to Mayo Clinic. This includes losing weight and getting the right amount of exercise. Avoid foods with trans fat and reduce the amount of cholesterol in the diet. If changing a person's lifestyle is not enough, certain medicines, such as statins and omega-3 fatty acid supplements, can help lower triglyceride levels.
