Thyroid Problems Q & A

What do you need to know about thyroid hormones?

Your thyroid gland produces several hormones, including calcitonin, which helps regulate blood levels of calcium. When thyroid problems arise, however, it’s usually due to an imbalance in the thyroid hormones that regulate your metabolism.

Thyroid hormones influence every part of your body, including:

  • Breathing and heart rate
  • Muscle strength
  • Body weight
  • Body temperature
  • Nervous system
  • Protein production
  • Cholesterol levels
  • Menstrual cycles

Which thyroid problems are most common?

The two most common thyroid problems develop when the gland produces too little or too much thyroid hormone:


Hypothyroidism exists when your thyroid gland is underactive and produces too little thyroid hormone. You may experience symptoms such as:

  • Weight gain
  • Fatigue
  • Dry skin
  • Puffy face
  • Hoarseness
  • Muscle aches and joint pain
  • High cholesterol
  • Sensitivity to cold


Hyperthyroidism arises from an overactive thyroid gland that produces too much thyroid hormone. Symptoms include:

  • Weight loss
  • Muscle weakness
  • Nervousness or anxiety
  • Tremor in your hands and fingers
  • Difficulty sleeping
  • Thinning skin
  • Enlarged thyroid gland (goiter)
  • More frequent bowel movements

What are thyroid nodules?

Thyroid nodules are small lumps on your thyroid that can be fluid-filled cysts or may consist of thyroid tissue. They usually don’t cause symptoms unless they become large, which happens in about 5% of people with nodules.

Most nodules aren’t cancerous, but large nodules may cause hyperthyroidism or make it hard to swallow, so you should have them examined by Dr. Fernandez.

What other health complications develop due to thyroid problems?

Untreated hypothyroidism and hyperthyroidism can have a severe impact on your heart. Hypothyroidism causes high cholesterol and an enlarged heart, while hyperthyroidism may lead to a rapid or irregular heartbeat or congestive heart failure.

Hypothyroidism also correlates with adrenal fatigue and infertility in women. Hyperthyroidism can increase your risk for osteoporosis.

How are thyroid problems treated?

Dr. Fernandez always develops an individualized plan that treats your hormone imbalance and underlying health problems.

Treatment for hypothyroidism typically includes thyroid hormone replacement. Hyperthyroidism is treatable with several types of medications that directly affect the thyroid gland to decrease hormone production.

If you suspect you may have a thyroid problem, please call or book an appointment so it can be evaluated by Dr. Fernandez and you can begin treatment to restore your health.
