How to Diagnose an Overactive Thyroid

If you are experiencing multiple symptoms of an overactive thyroid, it is important to seek medical assistance. Your doctor can order a thyroid function test to look at the levels of T4 and thyroid-stimulating hormone (TSH) in your blood. Other tests may also be ordered to rule out other conditions. Depending on the results, you may be prescribed medication, lifestyle changes, or further testing.

Managing an Overactive Thyroid

Once your diagnosis has been confirmed, your doctor may recommend managing your condition with medication and lifestyle changes. Some lifestyle changes that can help include:

  • Getting enough sleep

Your doctor may also prescribe medications to help control your symptoms and slow down your metabolism. It is important to take your medication as directed and follow up with your doctor with any questions or concerns.


If you think you may have an overactive thyroid, it is important to seek medical attention. While managing this condition can be challenging, treatment can help reduce symptoms and improve your overall quality of life.
