Myxedema
Myxedema is a term used in medicine to describe a severe form of hypothyroidism, a condition characterized by an underactive thyroid gland. The term is often used interchangeably with hypothyroidism, but myxedema specifically refers to a severe and life-threatening form of the condition.
Symptoms[edit | edit source]
The symptoms of myxedema can vary widely and may include fatigue, weight gain, cold intolerance, constipation, and depression. In severe cases, myxedema can lead to a life-threatening condition known as myxedema coma, which is characterized by decreased breathing, low blood pressure, low body temperature, and unresponsiveness.
Causes[edit | edit source]
Myxedema is most commonly caused by an underactive thyroid gland, which can be due to a variety of factors including autoimmune disease, certain medications, and surgical removal of the thyroid gland. Other causes can include pituitary or hypothalamic disease, severe illness, or certain medications.
Diagnosis[edit | edit source]
Diagnosis of myxedema is typically based on a combination of physical examination findings and laboratory tests. These tests may include measurements of thyroid hormone levels in the blood, as well as imaging studies of the thyroid gland.
Treatment[edit | edit source]
Treatment for myxedema typically involves replacement of the missing thyroid hormone, usually with a medication called levothyroxine. In severe cases, hospitalization may be required for intensive care and treatment.
