According to the American Thyroid Association (ATA), roughly 5-percent of U.S. adults suffer from hypothyroidism, or an underactive thyroid, making it the most prevalent immune disease in North America. An underactive thyroid results when the body doesn’t produce adequate thyroid hormone, thus affecting both normal brain, mood, and body function. Sadly the National Academy of Hypothyroidism, reports that 60-percent of those with thyroid disease don’t realize that they have a health issue due to a presentation of very commonplace symptoms, such as weight gain, moodiness, extreme fatigue, and digestive upset.

The following 15 symptoms could indicate an underactive thyroid, but it’s important to remember that symptoms occur on an individual basis. Each person will experience a different number of these symptoms and to varying degrees. Let’s take a look at what these symptoms are…
1. Unexplained Fatigue
Unexplained fatigue is one of the most common side effects of hypothyroidism. This is because the thyroid hormone controls energy levels and is responsible for letting the body know when it needs a nap. A perfect example (which is also on the extreme end) is when animals go into hibernation, they’ll experience low thyroid levels leading up to their seasonal nap. If you get an adequate amount of sleep (roughly 8 hours per night) and still struggle to get up in the morning, you may suffer from hypothyroidism. Many diagnosed patients report dealing with unexplained and severe forms of exhaustion throughout the day, even after a night of restful sleep.
“Thyroid hormone receives signals from the brain and coordinates cells to change their functions, depending on what else is going on in your body,” says Healthline. “Those with high levels of thyroid hormone feel nervous and jittery. In contrast, people with low levels of thyroid hormone feel exhausted and sluggish.”
