Thyroid Problems Q & A

What is hypothyroidism?

One of the most common conditions of the thyroid is hypothyroidism, when your thyroid gland fails to produce enough thyroid hormone. It can be caused by an autoimmune disorder or surgical removal of the thyroid gland due to cancer.

Symptoms of hypothyroidism include:

  • Unexplained weight gain
  • Fatigue and depression
  • Increased sensitivity to cold
  • Irregular menstrual periods
  • Slowed heart rate
  • Dry skin
  • Constipation
  • Puffy face
  • Muscle aches


What is hyperthyroidism?

Hyperthyroidism is diagnosed when your thyroid overproduces hormones. It can be caused by Grave’s disease, inflammation of the thyroid, or pituitary gland malfunction. Symptoms include:

  • Difficulty sleeping
  • Irritability and nervousness
  • Appetite changes
  • Heart palpitations
  • Tremors and shakiness
  • Heat intolerance
  • Shortness of breath


What are the symptoms of thyroid cancer?

Thyroid cancer is rare and often has no symptoms, but some people do develop a lump in the neck and hoarseness of voice. Usually, thyroid cancer is detected during a routine physical, so it’s important to get checked regularly.


How are thyroid conditions diagnosed?

If you are experiencing symptoms of a thyroid disorder, Dr. Doyle performs a comprehensive physical exam and medical review. She orders blood tests to measure the amount of thyroid your body is producing.

Usually, a low level of the hormone thyroxine and high level of the hormone TSH indicate an underactive thyroid, or hypothyroidism. High levels of thyroxine and low levels of TSH indicate an overactive thyroid, or hyperthyroidism.


How are thyroid conditions treated?

In cases of hypothyroidism, Dr. Doyle typically prescribes levothyroxine, a synthetic version of the thyroid hormone. This helps you achieve normal thyroid hormone levels, relieving your symptoms. You take it orally and daily; the dosage is personalized to you.

Hyperthyroidism is usually treated with oral radioactive iodine, which helps to shrink the thyroid gland. Anti-thyroid medications are also available. Dr. Doyle considers the severity of your condition and symptoms when making a treatment plan.

Thyroid cancer usually requires surgery to remove the cancerous tissue on the thyroid and any surrounding lymph nodes. You then take synthetic thyroid hormone for the rest of your life to make up for the missing gland. Regular monitoring ensures you’re always getting the right dosage for you.
