Medicines:

• Thyroid hormone replacement helps bring your thyroid hormone level back to normal.
• Heart medicine may help strengthen or regulate your heartbeat.

Tests:

• Blood tests may be done to monitor your thyroid hormone level.
• A thyroid scan may show how well your thyroid is working. Radioactive liquid is put into your IV or is given to you to drink. The part of your thyroid gland that still works absorbs the liquid. Two to 48 hours later, healthcare providers use a machine called a scintillator to take pictures of your thyroid. Tell the provider if you know or think you may be pregnant. The radioactive liquid may harm an unborn baby.
• An ultrasound uses sound waves to show pictures of your thyroid on a monitor.
• An EKG test records your heart rhythm and how fast your heart beats.

RISKS:

You may develop high cholesterol. Without treatment, hypothyroidism can become a life-threatening condition called myxedema. Myxedema can cause swelling in your legs, lungs, or around your heart.
