Types of Thyroid Disorders and Their Common Symptoms

Thyroid disorders (1) Thyroid disorders include several types of conditions. It can also include the production of too much or too little thyroid hormone by the thyroid gland. Thyroid disorders should not be overlooked or minimized as they can affect energy levels, mood, heart rate, bone health, and other vital functions that keep the body working optimally. Therefore, it is important to understand the types of thyroid disorders and know their common symptoms:


This thyroid disorder means the thyroid is not producing enough thyroid hormone. The thyroid gland is underactive, causing the body’s functions to slow down. It can be caused by damage from radiation treatment or the removal of the thyroid gland, among other causes. Hypothyroidism currently impacts about 4.3% of individuals 12 years of age or older. Symptoms of this condition include:

  • Stunted growth
  • Abnormal bone development
  • Weight gain
  • Tiredness
  • Depression
  • Memory problems
  • Increased sensitivity
  • Dry hair and skin
  • Slow heart rate
  • Fertility problems


Hyperthyroidism is another common type of thyroid disorder. It indicates that the thyroid is producing excessively, meaning the thyroid gland is overactive. This causes the functions of the body to speed up. One common cause of hyperthyroidism is Graves’ disease, representing about 70% of the people diagnosed with overactive thyroid, but there are other causes as well. Hyperthyroidism generally impacts between 1 and 3% of people in America and is more common in women. Symptoms of hyperthyroidism include the following:

Thyroid Tumors

Thyroid nodules, or adenomas, are noncancerous growths. They are usually found on the inner surface of the thyroid gland and are small. The presence of a thyroid tumor will often result in hyperthyroidism as the adenoma itself can secrete the thyroid hormone. The following symptoms can indicate the presence of these nodules:

  • Voice changes like hoarseness
  • Difficulty swallowing
  • Sudden and rapid weight loss
  • Irregular or fast pulse
  • Swelling in the neck, you can see or feel
