Complications: Myxedema coma
• Myxedema coma, a life-threatening complication of hypothyroidism, characterized by swelling of the hands, face and feet, periorbital tissues.
• The disease may lead to coma and death.• Results from persistently low thyroid production• Coma can be precipitated by acute illness, rapid
withdrawal of thyroid medication, anesthesia and surgery, hypothermia and the use of sedatives and opiods analgesics.
• Symptoms include fatigue, mental impairment, cold intolerance, headaches.

Hypothyroidism (Myxedema)
• Occurs when thyroid gland fails to produce sufficient thyroid hormone.
• Deficiency of circulating thyroid hormone
• Often a final consequence of Hashimoto’s thyrioditis and Graves’ disease.
• Affects women more than men.
• Often causes an overall decrease in metabolism.
• Complications: Myxedema coma, miscarriage. Infertility, Wt gain, Alopecia, bradycardia
