About This Test

It is estimated that 20 million Americans have thyroid disease, and 60% of those who have it, may not be aware. Your thyroid is responsible for a number of functions in the body, including regulating your metabolism, producing hormones, and controlling your heart rate and muscle function. 

Thyroid dysfunction falls between two main categories: underactive thyroid (hypothyroidism) and overactive thyroid (hyperthyroidism). 

Symptoms of Hypothyroidism

  • Tiredness or overwhelming fatigue
  • Sensitivity to cold
  • Weight gain
  • Constipation
  • Depression
  • Muscle aches, weakness, or cramps 
  • Dry skin 
  • Brittle hair and nails 
  • Hair loss or thinning hair 
  • Irregular or heavy periods in female

Symptoms of Hyperthyroidism

  • Fatigue
  • Anxiety 
  • Frequent bowel movements 
  • Hair loss 
  • Tremors
  • Difficulty concentrating
  • Increased sensitivity to heat 
  • Irregular periods in females

It’s important to note that many of these symptoms overlap with other causes. Testing is the more effective way to determine the cause of your symptoms and take the next steps toward treating them.
