Common Underactive Thyroid Symptoms

NOTE: Underactive, hypoactive and low thyroid are all referring to the same thing. Hashimoto’s is the autoimmune disease that can cause the thyroid to under perform and hence become ‘underactive’.

How common are thyroid problems?

It is estimated that 1/8 women will have a thyroid disorder during their lifetime. WHAT?? 😮 I’ve even read stats that say up to 40% of women have thyroid problems. Men can have underactive thyroid problems too, but it is less common.

So many go un-diagnosed. 🙁 That means there are millions of people suffering from these common underactive thyroid symptoms needlessly. This is part of the reason I’m on a mission to spread awareness of thyroid issues and offer positive & practice education.

❌ There are several kinds of thyroid dysfunction – the most common being overactive (usually Graves Disease) and underactive (usually Hashimoto’s Disease).

👉 Hashimoto’s an auto-immune thyroid disease and is the most common form of hypo (under) active thyroid disease. I was diagnosed with Hashimoto’s when I was 23. 👈  

❓If you feel like something isn’t ‘quite right’ about your health, pay attention to these symptoms.

If that’s you, trust your gut, go to your doctor and get a full thyroid panel blood test

If you have several of the symptoms listed it’s worth speaking to your health practitioner and getting your thyroid tested.

Research shows that it takes about 7 years for Hashimoto’s patients to be symptomatic.

It’s usually only when symptomatic that a person might think to be tested and often it takes years even with symptoms to be diagnosed with Hashimoto’s.

If you have NOT been diagnosed with Hashimoto’s and you suspect you might have a problem with your thyroid, please go to a doctor and request a comprehensive thyroid blood test. You might be best to find an integrative doctor who is familiar with treating thyroid disease. At a bare minimum you will want to have your thyroid antibodies and TSH tested but also testing FT4, FT3 and reverse T3 is often recommended.

If you doctor won’t get you tested or won’t test for thyroid antibodies, either try to find a doctor who better understands thyroid conditions and their complexities or now that you can get blood tests done privately. is a private lab  that do a variety of different thyroid panel tests.
