Triglycerides

Triglycerides produce energy for your body. When you eat, your body converts any calories it doesn't need right away into triglycerides and stores them in your fat cells for later use. This process gives you energy when you haven't eaten for a time.

Cholesterol

Your body uses cholesterol--a waxy substance surrounded by a protein membrane-- to build cells and some hormones. Your liver also uses cholesterol to make bile acids that help digest food. Your body needs only a small amount of cholesterol for these processes.

Effects

Although triglycerides and cholesterol are both vital for the proper function of your body, you can have too much. High levels are considered a risk factor for heart disease.

Considerations

The first recommendations for managing both cholesterol and triglyceride levels are to maintain an ideal body weight, reduce the saturated fat, trans fat and cholesterol in your diet, eat lots of fruits and vegetables, and exercise regularly.

Medications

Many triglyceride and cholesterol lowering medications are available, but they do not work for everyone and can produce significant side effects. Work with your healthcare provider to decide what's best for you.
