2. Unexpected Weight Changes
One sign of thyroid problem is unexpected weight changes. Sufferers who experience hypothyroidism or hyperthyroidism may encounter rapid weight gain or weight loss, even those who constantly workout and have a strict nutritional diet may have a hard time losing or gaining weight because of this adverse effect or symptom. With hypothyroidism, your thyroid glands become inactive, hence it slows your metabolism and makes you gain more weight rather than lose it.
On other hand, hyperthyroidism causes your metabolism to increase and work faster than normal leaving you with rapid weight loss. It is recommended to check with your physician if you observe sudden changes in your weight.
