The thyroid is a small, butterfly-shaped gland located in the lower neck. It produces a specific group of hormones which control many of your body's activities including your metabolic health [1].

Weight gain, weight loss, fatigue or difficulty sleeping are all common signs of thyroid problems - each of which can have an impact on your day to day life. If you’re experiencing these symptoms and you would like to investigate further, you can check your thyroid function from the comfort of your own home.

How do you check thyroid problems from home?

The most reliable way to check thyroid problems from home is with an at-home lab test.

LetsGetChecked’s range of at-home Thyroid Tests measure key hormones and antibodies to help identify the presence of a thyroid disorder, such as hyperthyroidism (an over-active thyroid) or hypothyroidism (an under-active thyroid). Your test will be sent to the same labs used by doctors and hospitals, with online results in just 5 days. Our team of dedicated nurses will be on hand to help you understand your results and answer any questions you may have.

Indicators of thyroid problems

Hypothyroidism (Underactive Thyroid) occurs when the thyroid gland is not producing a sufficient level of thyroxine (T4) and triiodothyronine (T3).

Symptoms of Hypothyroidism include:

  • Weight gain
  • Fatigue or feeling tired all the time
  • Slow pulse or heart rate
  • Hair loss or thinning
  • Poor tolerance of the cold
  • Depression
  • Dry, coarse or thickened skin
  • Constipation
  • Hand tingling or pain (carpal tunnel syndrome)
  • Irregular period or low sex drive
  • Muscle cramps
  • Impaired memory

Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).

Symptoms of Hyperthyroidism include

  • Weight loss
  • Fatigue or feeling tired all the time
  • Increase or rapid heart rate
  • Tremors (usually in the hands)
  • Heat intolerance or excessive sweating
  • Difficulty sleeping
  • Excessive sweating or fever
  • Frequent bowel movements or diarrhea
  • Anxiety
  • Irregular period
  • Low sex drive
  • Enlarged thyroid gland (goiter)
  • Eye condition related to hyperthyroidism

LetsGetChecked’s at-home Thyroid Tests determine how your thyroid is performing by looking at thyroid stimulating hormone (TSH), free thyroxine (T4) and free triiodothyronine (T3). TSH is produced by the pituitary gland in the brain and it controls the production of T3 and T4 from the Thyroid gland.
