Subclinical Hypothyroidism

WHAT YOU NEED TO KNOW:

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.

WHILE YOU ARE HERE:

Informed consent

is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

You may need extra oxygen

if your blood oxygen level is lower than it should be. You may get oxygen through a mask placed over your nose and mouth or through small tubes placed in your nostrils. Ask your healthcare provider before you take off the mask or oxygen tubing.

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.

CARE AGREEMENT:
