Before we dive into the possible mental and emotional health symptoms of thyroid disorders, let’s first talk about the basics.

Here are a few important things you should know about thyroid function and disease:

  • Your thyroid is a butterfly-shaped gland at the base of your neck. It produces a variety of hormones that help control important bodily functions, including your metabolism, heart rate, body temperature, and more.
  • Women are 5 to 8 times more likely to have thyroid issues than men.
  • Thyroid disease affects more than 20 million Americans and many people with a thyroid disorder don’t know they have it.
  • Two of the most common thyroid disorders are characterized by an overactive thyroid (hyperthyroidism) or underactive thyroid (hypothyroidism).


What are early warning signs of thyroid problems?

If you’ve been feeling off for the past few months without knowing why, you may be experiencing a hormone imbalance tied to thyroid issues. Below are some of the most common symptoms that could be linked to thyroid dysfunction.

Some of the most common symptoms of hypothyroidism may include:

  • Weight gain, even without changes in your diet or activity level
  • Fatigue
  • Mood changes, including depression or anxiety
  • Chronic hoarse voice
  • Dry skin
  • Constipation
  • Puffy face
  • Joint pain
  • Muscle aches or weakness
  • Thinning hair or hair loss
  • Heavy or irregular periods
  • Infertility
  • Goiter (enlarged thyroid gland)

Common symptoms of hyperthyroidism may include:

  • Unintentional weight loss, even without dietary changes
  • Rapid heartbeat (tachycardia)
  • Irregular heartbeat (arrhythmia) and a pounding heart (palpitations)
  • Increased appetite
  • Mood changes, including nervousness, anxiety, and irritability
  • Hand and finger tremors
  • Sweating
  • Changes in your menstrual cycle
  • New or worsened heat sensitivity
  • More frequent bowel movements
  • Goiter (enlarged thyroid gland)
  • Fatigue
  • Weak muscles
  • Problems with your sleep
  • Thinner skin, which is more susceptible to cuts and bruises
  • Fine hair which easily breaks

Have you been experiencing some of these symptoms and you suspect your thyroid hormones may be off-balance?

Take the Everlywell Thyroid Test to measure the levels of three main thyroid-specific hormones in your body: TSH (thyroid-stimulating hormone), T3, and T4—plus thyroid antibodies (TPOab). Your test results could be the first step in helping you understand the hormonal influences behind some of the symptoms your body may be experiencing.

Thyroid disease and anxiety

As noted by the symptoms list above, in some cases thyroid disease may affect your mood. This includes anxiety, depression, and other mental health challenges. Generally, the more severe your thyroid disease, the more severe the mood changes may be.

If you have an overactive thyroid (hyperthyroidism), you may experience:

  • Restlessness
  • Anxiety
  • Irritability

If you have an underactive thyroid (hypothyroidism), you may experience:

  • Mild to severe fatigue
  • Depression
  • Anxiety
