Subclinical hypothyroidism is a condition that develops when your thyroid stimulating hormone (TSH) level is higher than normal. TSH is made in the brain and controls how much thyroid hormones are made. Thyroid hormones help control body temperature, heart rate, growth, and weight. Subclinical hypothyroidism can lead to hypothyroidism.

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 dye. Two to 48 hours later, healthcare providers use a machine called a scintillator to take pictures of your thyroid.
• An ultrasound uses sound waves to show pictures of your thyroid on a monitor.
• An EKG records your heart rhythm and how fast your heart beats.

RISKS:

Thyroid replacement hormone that is given in too high of a dose, may cause health problems. Without treatment, your condition may worsen and develop into hypothyroidism. Subclinical hypothyroidism may also increase your risk for heart disease, mental problems, depression, and low bone density.
