    • Myxedema coma is a life-threatening condition with a mortality rate of 20-40% despite treatment.
    • Myxedema is the term used to describe the accumulation of mucopolysaccharides in subcutaneous and other interstitial tissues.

    Clinical Manifestations of Hypothyroidism

    • Cardiovascular-related manifestations associated with hypothyroidism include bradycardia, decreased cardiac output, and increased peripheral vascular resistance.
    • A characteristic change in the skin due to severe hypothyroidism is dry, thick, and scaly skin.
    • The effect of severe hypothyroidism on body temperature is hypothermia.
    • A potential cognitive change characteristic of advanced hypothyroidism is dementia.
    • A potential respiratory complication associated with severe hypothyroidism is respiratory failure.
    • The effect of severe hypothyroidism on serum cholesterol level is elevated levels.
    • The term used to describe the decrease in metabolism resulting from the decrease in thyroid function is hypometabolism.

    Testing and Risk Factors
