Hyperthyroidism vs. Hypothyroidism: Examining the Thyroid’s Influence on Physical, Mental, and Emotional Health

Hyperthyroidism vs. Hypothyroidism: Examining the Thyroid’s Influence on Physical, Mental, and Emotional Health

By Thrive Reno’s Director of Primary Care Services Becky Barnett, PA-C

The thyroid is a small gland located just above the collarbone that creates and releases several hormones that are critical to many physical functions within the body. The thyroid’s hormones are also closely linked to a person’s mental and emotional health. 

According to the American Thyroid Association, 20 million or twelve percent of Americans have some form of thyroid dysfunction. Shockingly, sixty percent of individuals experiencing thyroid dysfunction are unaware of their condition. While the causes of thyroid issues are largely unknown, fortunately there are ways to treat thyroid issues.

Explore how thyroid dysfunction can disrupt one’s physical, mental, and emotional health, and learn about common treatment methods.


When the thyroid produces too many hormones, it is considered overactive — a condition called hyperthyroidism. An overabundance of thyroid hormones can accelerate the body’s metabolic functions as well as cause symptoms of anxiety

Physical Symptoms of Hyperthyroidism

  • Enlarged thyroid gland
  • Rapid heart rate
  • Difficulty sleeping
  • Restlessness
  • Increased appetite
  • Increased frequency of bowel movements
  • Irregular menstruation cycles
  • Excessive sweating
  • Trembling or shaking

Mental and Emotional Symptoms of Hyperthyroidism

  • Anxiousness
  • Nervousness
  • Irritability
  • Persistent worry
  • Difficulty thinking or concentrating
  • Forgetfulness
  • Feeling overwhelmed
  • Difficulty relaxing

Treatment for Hyperthyroidism

Hyperthyroidism affects less than one percent of the population. A person experiencing hyperthyroidism would typically visit an endocrinologist, which is a physician that specializes in hormones. Oral medications, radioactive iodine treatments, and surgery can be used to slow the thyroid’s production of hormones.


An underactive thyroid, or hypothyroidism, produces too few hormones which can lead to decreased metabolic functioning as well as symptoms of depression

Physical Symptoms of Hypothyroidism

  • Slowed metabolism
  • Slowed heart rate
  • High cholesterol
  • Decreased core body temperature
  • Constipation
  • Muscle pain and weakness
  • Dry skin and hair

Mental and Emotional Symptoms of Hypothyroidism

  • Depression
  • Fatigue
  • Social withdrawal
  • Apathy
  • Anxiousness
  • Irritability
  • Forgetfulness
  • Sluggishness
  • Confusion
  • Delayed reaction times
  • Difficulty concentrating

Treatment for Hypothyroidism

Hypothyroidism is a more common condition than hyperthyroidism and can typically be treated by primary care providers. Thyroid replacement hormones in the form of oral medications are often prescribed to manage hypothyroidism.


Many health care providers don’t routinely screen clients for thyroid dysfunction. So, if you’re concerned that you’re experiencing symptoms of an underactive or overactive thyroid, we encourage you to ask your health care provider to assess your thyroid. A simple blood test can provide an overview of thyroid hormone levels. 


Thrive’s team of physicians, psychiatrists, therapists, nutritionists, and movement specialists collaborate to promote our clients’ overall well-being. If you’re struggling with physical, mental, or emotional health concerns, reach out to us to learn more about how we can help you achieve better health.
