Thyroid Symptom Checker
Thyroid Symptom Checker
A gentle self-assessment to help you understand whether your symptoms may fit a thyroid pattern
How to use this checker
Choose the answer that best reflects your experience over the past 3 months.
Both hypothyroidism and hyperthyroidism can cause wide-ranging symptoms, and many of those symptoms overlap with other conditions. A proper assessment usually involves a symptom history, an examination, and thyroid blood tests.
If you have chest pain, fainting, severe palpitations, shortness of breath, confusion, severe weakness, or a rapidly enlarging neck swelling, seek urgent medical care. If you notice persistent neck swelling, thyroid eye symptoms, very infrequent periods, or new symptoms that are worsening, it is worth arranging a medical review.
Could your symptoms fit a thyroid pattern?
This gentle self-assessment is designed to help you notice whether changes in energy, mood, sleep, temperature tolerance, weight, concentration, digestion, skin, hair, or menstrual pattern may fit into a broader picture of thyroid health. Thyroid symptoms can be caused by an underactive or overactive thyroid, and diagnosis is usually confirmed with blood tests.
It is simple, supportive, and designed to help you feel informed without feeling overwhelmed.
Your symptoms deserve clarity
This checker is a starting point, not a final answer. If your results reflect a pattern you have been living with for a while, keeping a note of your symptoms can help you feel more prepared for your next step and more specific in a conversation with your GP or clinician.
