Thyroid Disorder Q & A

What is a thyroid disorder?

The thyroid is a small gland near the base of your neck. It’s part of the endocrine system and produces hormones that regulate your metabolism. A thyroid disorder occurs when your thyroid gland produces too many or too few hormones. Without diagnosis and treatment, thyroid disorders increase your risk of other, more serious health problems.

What are some common thyroid disorders?

The team at Endocrinology and Osteoporosis Centers of Texas treats all types of thyroid disorders, including:


Hypothyroidism occurs when your thyroid produces too few hormones. Common symptoms include fatigue, dry skin, memory problems, and constipation. 


Hyperthyroidism affects about 1% of women and occurs when your thyroid produces too many hormones. Common symptoms include restlessness, nervousness, irritability, and trouble sleeping. 

Hashimoto’s thyroiditis

Hashimoto’s thyroiditis causes your body’s immune system to attack the thyroid. Over time, this prevents it from producing enough hormones, resulting in hypothyroidism. Common symptoms include fatigue, mild weight gain, and thinning hair.

Grave’s disease

Grave’s disease affects about 1 in every 200 people.  It causes your body to mistakenly attack the thyroid, causing it to overproduce hormones. Common symptoms include anxiety, hand tremors, and irritability.


Goiters cause your thyroid gland to swell and expand. They’re noncancerous and typically occur due to iodine deficiency. Symptoms include swelling or tightness in the neck, coughing, or difficulty breathing.

Thyroid nodules

Thyroid nodules are small growths that develop on your thyroid gland. Most are benign, but some are cancerous. Most nodules are so little they don’t cause symptoms. If they continue to grow, you might experience neck pain or difficulty breathing. 

How is a thyroid disorder diagnosed?

The team at Endocrinology and Osteoporosis Centers of Texas diagnoses a thyroid disorder by conducting a physical exam, reviewing your health history, and asking about your symptoms and lifestyle. Afterward, they order several blood tests, including:

  • Thyroid-stimulating hormone (TSH)
  • T4: Thyroxine
  • FT4: Free T4 or free thyroxine
  • T3: Triiodothyronine
  • FT3: Free T3 or triiodothyronine

These tests cannot diagnose a specific disorder, but they can alert the team to low, high, or otherwise abnormal hormone production.

How is a thyroid disorder treated?

Treatment of a thyroid disorder typically includes a combination of healthy lifestyle changes and prescription medication. Depending on the type of condition you have, the team might prescribe anti-thyroid drugs, beta-blockers, or radioactive iodine.

If medication and lifestyle changes don’t ease your symptoms, thyroidectomy may be necessary. This type of surgery removes your thyroid gland to stop it from making hormones.
