The combination of high triglycerides and low high-density lipoprotein (HDL) cholesterol can arise from physical inactivity, drinking too much alcohol, and obesity. It can lead to serious health problems, such as high blood pressure and atherosclerosis.
HDL is a form of cholesterol that carries it back into the liver, removing it from the body. It is known as “good” cholesterol. Low-density lipoprotein (LDL) is known as “bad” cholesterol. Triglycerides are a different type of fat altogether.
This article explains what can happen when an individual has high triglycerides and low HDL levels. It also outlines the possible causes and lists the normal levels of triglycerides, HDL, and LDL.
Finally, it discusses how to manage high triglycerides and low HDL.
- eating too many foods high in saturated fats
- physical inactivity
- drinking too much alcohol
- kidney disease
- thyroid disease
- overweight or obesity

Scientists have determined the normal blood lipid levels for the average adult. Measurements are in milligrams (mg) per deciliter (dL) of blood (mg/dL). According to a
- Triglycerides: Below 150 mg/dL
- HDL: Between 40 and 60 mg/dL
- LDL: Less than 100 mg/dL

The combination of high triglycerides and low HDL cholesterol levels links to several health problems, including:
Cardiovascular disease or atherosclerosis
Coronary heart disease is a serious condition that affects the arteries supplying blood to the heart. In people with coronary heart disease, these arteries are either narrower than they should be or plaque buildups have partially blocked them. This can lead to atherosclerosis, which is a toughening of the arteries.
As the American Heart Association explains, the same combination can
High blood pressure
HBP, or hypertension, happens when there is too much pressure in an individual’s blood vessels. Although it can be asymptomatic for many years, long-term and untreated HBP can lead to serious health problems, including kidney disease and heart failure.
Nonalcoholic fatty liver disease
Nonalcoholic fatty liver disease is when too much fat builds up inside a person’s liver. In a healthy adult, the liver should contain little to no fat. Nonalcoholic fatty liver disease can cause weakness and abdominal pain.
Research suggests that high triglycerides and low HDL levels can contribute to developing nonalcoholic fatty liver disease.
The following lifestyle modifications
- eating a nutritious diet containing heart-healthy foods
- increasing daily movement and getting regular exercise
- losing weight if necessary and maintaining a moderate body mass index (BMI)
- managing stress
- quitting smoking if applicable and avoiding passive smoking
- fibrates, which work by acting on enzymes that metabolize lipids
- concentrated omega-3 fatty acids
- ezetimibe, a medication that reduces the absorption of cholesterol from within the intestine
For low HDL levels, the
Doctors can also prescribe statins for both conditions. These work by inhibiting an enzyme that contributes to cholesterol production in the liver.

High triglycerides and low HDL levels can occur for many reasons, including eating too much saturated fat, drinking too much alcohol, and being inactive. Diabetes, thyroid problems, and kidney disease link with high triglycerides and low HDL.
Stroke, heart attack, and nonalcoholic fatty liver disease are possible complications.
Doctors recommend lifestyle modifications to help people improve their levels of HDL and triglycerides. These include eating a nutritious diet and being active. Medications, such as statins, can also help.
