myxödem

Myxedema is a rare, chronic condition characterized by the accumulation of mucopolysaccharides in the skin and other tissues, primarily due to hypothyroidism. This buildup leads to non-pitting edema, which manifests as swelling in the face, eyelids, tongue, and extremities. The term "myxedema" originates from the Greek word "myxos," meaning mucus, reflecting the gelatinous appearance of affected tissues.

The most common cause of myxedema is untreated or poorly managed hypothyroidism, where the thyroid gland does not produce sufficient thyroid hormones. Without adequate hormone replacement, the body's metabolic processes slow down, leading to the accumulation of mucopolysaccharides. Other potential causes include autoimmune thyroiditis, thyroid surgery, or radiation therapy for thyroid cancer.

Symptoms of myxedema can vary widely but often include dry, coarse skin; hoarseness; cold intolerance; fatigue; and weight gain. In severe cases, myxedema coma—a life-threatening condition—may occur, characterized by hypothermia, hypoventilation, and coma. Diagnosis typically involves blood tests measuring thyroid hormone levels, TSH (thyroid-stimulating hormone), and antithyroid antibodies, along with physical examination findings.

Treatment primarily focuses on restoring thyroid hormone levels through medication, such as levothyroxine. In severe cases, hospitalization may be required for supportive care, including intravenous fluids, oxygen therapy, and close monitoring. Early diagnosis and treatment are crucial to prevent complications and improve quality of life. Myxedema is generally manageable with proper thyroid hormone replacement and regular medical follow-up.
