30 Thyroid Symptoms That Are Too Important to Ignore

1. Unexplained Weight Loss
Your thyroid acts like your body's thermostat by releasing hormones (mainly T3 and T4) that control how fast your metabolism runs. When these hormones are too high, your metabolism speeds up, burning calories faster than normal---even if your diet and exercise remain unchanged. If you suddenly start losing weight without any changes to your diet or exercise routine, it could be a sign that your thyroid is out of balance.
