How the Thyroid Works: Your thyroid extracts this necessary ingredient from your bloodstream and uses it to make two kinds of thyroid hormone: thyroxine, also called T4 because it contains four iodine atoms, and triiodothyronine, or T3, which contains three iodine atoms. T3 is made from T4 when one atom is removed, a conversion that occurs mostly outside the thyroid in organs and tissues where T3 is used the most, such as the liver, the kidneys and the brain. Iodine comes from the diet and is found in iodized table salt, seafood, bread and milk.

Two Challenges for Older Patients and Thyroid Disease: Hyperthyroidism (excessive production of thyroid hormone) and Hypothyroidism (reduced production of thyroid hormone).
Treatment of the Older Patient with Hyperthyroidism: Antithyroid drugs and radioactive iodine. Surgery is rare.
Treatment of the Older Patient with Hypothyroidism: Pure synthetic thyroxine (L-T4), taken daily by mouth.

How to Keep the Thyroid Healthy: "Simply put, if your thyroid gland isn’t working properly, neither are you.
How do You Know if You Have a Thyroid Problem?
First, you must understand how to recognize the symptoms and risk factors of thyroid disease. Since many symptoms may be hidden or mimic other diseases and conditions, the best way to know for sure is to ask your doctor for a TSH (thyroid-stimulating hormone) test, a simple blood test to verify your thyroid gland’s condition. Also, take a minute and perform a self Neck Check. And because thyroid disease often runs in families, examinations of your family members and a review of their medical histories may reveal other individuals with thyroid problems.
What are Some of the Reasons to Consider a Thyroid Evaluation?
Family History: A familiar place to look for thyroid disorder signs and symptoms is your family tree. If you have a first-degree relative (a parent, sibling or child) with thyroid disease, you would benefit from thyroid evaluation. Women are much more likely to be thyroid patients than men; however, the gene pool runs through both.
Prescription Medications: If you are taking Lithium or Amiodarone, you should consider a thyroid evaluation.
Radiation Therapy to the head or neck: If you have had any of the following radiation therapies, you should consider a thyroid evaluation: radiation therapy for tonsils, radiation therapy for an enlarged thymus, or radiation therapy for acne.
Chernobyl: If you lived near Chernobyl at the time of the 1986 nuclear accident, you should consider a thyroid evaluation." Quoted from EmPower
