Familial lipoprotein lipase deficiency

  • Alternative Names

    Type I hyperlipoproteinemia; Familial chylomicronemia


    Treatment aims to control the symptoms and blood triglyceride levels with a very low-fat diet. You should eat no more than 20 grams of fat per day to prevent the symptoms from coming back.

    Twenty grams of fat is equal to one of the following:

    • 2 8-ounce glasses of whole milk
    • 4 teaspoons of margarine
    • 4-ounce serving of meat

    The average American diet has a fat content of up to 45% of total calories. Fat-soluble vitamins A, D, E, and K and mineral supplements are recommended for people who eat a very low-fat diet. Dietary counseling may be helpful for patients who are trying to stick to a strict diet and still get enough calories and nutrients.
