Thyroid Q & A

What is the thyroid?

Your thyroid is a butterfly-shaped gland just below your Adam’s apple. It’s part of the endocrine system, which is responsible for regulating numerous systems and functions in your body. When it functions properly, it produces hormones that are secreted into your bloodstream and carried to every tissue in your body.

These hormones help you stay warm, keep your brain and heart working, and affect many other organs and muscles. If your thyroid produces too many hormones (hyperthyroidism), or too few hormones (hypothyroidism), you may experience a variety of unpleasant symptoms that could become serious health issues if left untreated.

What are the symptoms of hyperthyroidism?

When you have an overactive thyroid, as is the case with hyperthyroidism, nearly every system in your body speeds up. People with hyperthyroidism often experience several of the following conditions and symptoms:

  • Hand tremors
  • Racing heart
  • Anxiety and nervousness
  • Increased sweating
  • Trouble sleeping and relaxing
  • Muscle weakness
  • Thinning skin
  • Brittle hair
  • Frequent bowel movements
  • Excessive weight loss

With hyperthyroidism, you may have a lot of energy, but you probably feel tired, too, as your body breaks down. Graves’ disease is one of the most common forms of hyperthyroidism and sometimes causes your eyes to bulge.

What are the symptoms of hypothyroidism?

Hypothyroidism is when your thyroid gland is underactive, so your body doesn’t receive enough hormones. When you don’t produce enough hormones, your body tends to slow down. Typical signs of an underactive thyroid include:

  • Feeling tired all the time
  • Excessive weight gain or inability to lose weight
  • Constipation
  • Slow heart rate
  • Dry skin
  • Depression
  • Trouble remembering things
  • Feeling cold

Hashimoto’s disease is the most common cause of hypothyroidism.

What treatments are available for thyroid problems?

Your treatment depends on the type of thyroid disorder you have. Dr. Kim is an expert in thyroid diseases, so he customizes a treatment plan that addresses your specific health issues. He may recommend medications for hyperthyroidism and hypothyroidism, or in some cases, surgery.

Dr. Kim specializes in robotic and minimally invasive surgical procedures of the thyroid and parathyroid, so he also treats conditions like:
