Is Life An Emotional Roller Coaster? WHY Thyroid Health Affects Mood

If you’re feeling grouchy, anxious, and just not your normal happy self there could be a reason. You may be surprised to learn your thyroid health affects your mood!

Hypothyroidism: YES, It Impacts Mood

How do you feel right now? Did you know that if you’ve been diagnosed with a hypothyroid disorder it could be seriously impacting your emotional well-being?

THYROID FACT: Mood changes, depression and anxiety can be symptoms of hypothyroidism but this important link is often missed.

The reason is simple. The thyroid hormones are highly active in the emotional areas of the brain. These hormones play a vital role in regulating production of the brain neurotransmitters that help regulate our mood, even the ability to think clearly.

So as you can imagine, life feels good and you have an optimistic outlook when your thyroid is running smoothly. The flip side of course is that thyroid dysfunction can give rise to emotional health issues.

Get Your Thyroid Checked

The good news is, it doesn’t have to be this way. If you suspect a thyroid hormone imbalance is is taking a toll on your emotional health it’s vital you speak to a thyroid-literate doctor who understands thyroid problems.

Even though the impact is on your mood, you must address the underlying thyroid disorder to help improve your emotional state. I suggest you look more deeply at triggers such as the foods you eat, nutritional deficiencies, chronic infections, toxins, stress, and any genetic influences. You will see these topics are all covered regularly here on the ThyroSynergy® blog.
