High Triglyceride Symptoms: An Overview
High triglycerides do not cause symptoms, so many people are unaware that their
triglyceride level is too high. Most people find out they have high triglycerides though a blood test, such as a lipid panel.
Impact of High Triglycerides
High triglycerides can increase your risk for developing certain medical conditions, including
heart disease and
heart attack. When triglycerides in the blood are high, they can build up on your artery walls (as can
cholesterol and other debris). This buildup is called
plaque. Over time, plaque can narrow the blood vessels, and sometimes this buildup may even block your blood vessels completely. Plaque buildup on your blood vessel walls is called
atherosclerosis.
Nobody knows why this buildup happens, but a narrowed or blocked blood vessel can prevent blood from getting to where it needs to go. Without blood, tissues will die.
For example, if the blocked vessel is in your brain, it can cause a
stroke. Blockages can also occur in the blood vessels -- called the coronary arteries -- that carry blood to the heart muscle. This blockage process is called coronary
heart disease, and it can lead to a heart attack.
Atherosclerosis can affect all of your organ systems; however, the organ most seriously affected by both high triglycerides and atherosclerosis is the heart.
For people with high triglycerides, the process of atherosclerosis occurs more quickly when
HDL (
good cholesterol) levels are low.
For people with very high levels of triglycerides in the blood (over 1,000 mg/dL), high triglycerides can also cause other conditions, including:
