Hypothyroidism - primary Health Article

Complications

Myxedema coma, the most severe form of hypothyroidism, is rare. It may be caused by an infection, illness, exposure to cold, or certain medications. Symptoms and signs of myxedema coma include:

• Unresponsiveness
• Decreased breathing
• Low blood pressure
• Low blood sugar
• Below-normal temperature

Other complications include:

• Heart disease
• Increased risk of infection
• Infertility
• Miscarriage
• Pituitary tumors

Calling your health care provider

Call your health care provider if signs or symptoms of hypothyroidism or myxedema are present

Call your health care provider if restlessness, rapid weight loss, heat intolerance, rapid heart rate, excessive sweating, or symptoms of hyperthyroidism occur after beginning thyroid replacement.

Prevention

Primary hypothyroidism is preventable by supplemental iodine in areas where iodine in the food supply is low. Otherwise, the condition is not preventable. Awareness of risk may allow early diagnosis and treatment. Some experts advocate screening TSH testing in certain high risk groups (e.g., women older than 50 years).
