Cholesterol & Thyroid Disease

Millions of Americans suffer from underactive or overactive thyroids, and large numbers of them are undiagnosed. The American Association of Clinical Endocrinologists has determined a link between thyroid functioning and high cholesterol levels.

  1. Hypothyroidism

    • Underactive thyroid is characterized by the reduced effectiveness of the thyroid gland. During hypothyroidism, cholesterol levels are increased due to the body's inability to produce the thyroxine, which is a hormone that breaks down cholesterol.

    LDL Receptors

    • LDL receptors remove bad cholesterol from the body. During hypothyroidism, LDL builds up in the bloodstream and increases total cholesterol levels in the body.

    Hypothyroid and Heart Disease

    • Hypothyroidism increases the likelihood of developing heart disease. High cholesterol levels contribute to the development of heart disease and can cause long-term cardiovascular problems.

    Hyperthyroid

    • Overactive thyroid also increases the risk of developing cardiovascular disease. However, since LDL receptors are increased, cholesterol levels are dramatically decreased during hyperthyroidism.

    Treatment

    • Thyroid problems can be diagnosed through blood tests; when being tested for thyroid problems, be sure to request an additional cholesterol test. Hypothyroid and hyperthyroid are treated through the use of hormone replacement medication that can regulate thyroid functioning.
