Hypothyroidism - secondary Health Article

Expectations (prognosis)

With early treatment, return to the normal state is usual. However, relapses will occur if the medication is not continued. Myxedema coma can result in death.

Complications

Myxedema coma, the most severe form of hypothyroidism, is rare. It may be brought on 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

• Heart disease
• Infertility
• Miscarriage in pregnant women
• Adrenal crisis, if thyroid replacement is begun prior to steroid treatment in hypoadrenal patients

Calling your health care provider

Call your health care provider if signs of hypothyroidism are present, or if chest pain or rapid heartbeat occur.

Call your provider if restlessness, rapid weight loss, sweating, or other symptoms occur after beginning treatment for this disorder.

Call your provider if headache, visual loss, or breast discharge occur.

Prevention

This condition may not be preventable. Awareness of risk may allow early diagnosis and treatment.
