5.Having some mood swings.
When you experience some moods that change very fast and without some explanation, it might be a sign that the thyroid isn’t working well. Having hypothyroidism might make one feel so depressed or in low spirits. At other times, you might feel very anxious. However, feeling angry, worked up or becoming easily irritated than usual, might be a symptom that the thyroid in your body is hyperactive. When this hormone becomes overproduced, the body will become overheated or fired up.
