Your thyroid gland releases a hormone with the unoriginal name of "thyroid hormone." When your thyroid hormone is too high, you may suffer from what's known as "hyperthyroidism" - a condition where your thyroid produces too much of its hormone in the body.
An overactive thyroid isn't always a problem. There are those with hyperthyroidism that show no symptoms, or show symptoms so minor that they never realize they have a thyroid problem. But in some cases, an overactive thyroid gland can lead to severe anxiety, possibly with panic attacks.
Your Mind Can Control Your Body
While hyperthyroidism is a medical problem that requires medical assistance, the mind is also a powerful tool, and if you can learn to cope with anxiety you may be able to reduce anxiety caused by your thyroid hormone. Take my anxiety test to learn more.
Understanding Your Anxiety
If you suspect you have hyperthyroid, you need to talk to your doctor. There are very easy blood tests that can tell you if you have this condition. Many people self-diagnose because they're convinced their anxieties have to be physical, and while hyperthyroid isn't a rare condition (it affects 2% of women and 0.2% of men) it is not likely to be the cause of your anxiety. Take my anxiety test to receive an anxiety profile.
So make sure you see your doctor first, and note that even if you have hyperthyroid, your anxiety may still have developed for reasons unrelated to your thyroid hormone.
Anxiety as a Symptom of Hyperthyroidism
If you have been diagnosed with an overactive thyroid, it is possible that it is one of the contributing factors to your anxiety. In fact, anxiety is considered one of the most likely effects of hyperthyroidism.
That's because the thyroid hormone essentially activates the entire body. It speeds up your body's metabolism in a way that causes your entire sympathetic nervous system to be more active. That means that not only are you experiencing anxiety, you are also experiencing:
- Nervous tremors/shaking
- Heart palpitations/racing heart
If these look like anxiety symptoms, that's because they are. That's one of the reasons that it's hard to tell the difference between anxiety produced by an overactive thyroid and anxiety that is caused by something else. The two share many of the exact same symptoms, making it very difficult to distinguish them from each other clinically without a blood test.
And one of the reasons they may be difficult to distinguish is because they are both anxiety. Even if an overactive hormone is causing that anxiety, it is still anxiety nonetheless.
Symptoms Causing Anxiety
Similarly, the two can develop simultaneously, but the cause may not be as clear. Some people may develop anxiety not because their thyroid hormone is causing it, but because their thyroid hormone is causing other strange symptoms that lead to anxiety. Hyperthyroid causes many symptoms that can cause their own separate anxiety, such as:
- Weight loss
- Heart palpitations
- Hair loss
- Swelled eye muscles
These symptoms - along with many others - can themselves cause anxiety because they are so foreign to the person experiencing them. Any time someone experiences strange sensations they run the risk of developing nervousness and anxiety as a result, especially if some of those symptoms - like heart palpitations - are scary.
Fighting Your Anxiety and Your Hyperthyroidism
Because hyperthyroid is a medical condition, you need to talk to your doctor. There are many very safe ways of managing an overactive thyroid, and your doctor will talk to you about the method that works best for you.
But note that it's difficult to know if anxiety will go away, and it is in your best interests to continue to focus on ways to reduce your anxiety, like exercise, proper eating, and various relaxation strategies. You may even want to see a therapist if there's one in your area.
I've helped hundreds of those with anxiety learn to control it with my free 7 minute anxiety test. This test is an evaluation tool that allows you to learn more about your anxiety and how to treat it.
