Fatigue and weakness
Iodine shortage is often associated with fatigue and weakness. According to some research, approximately 80% of persons who have low thyroid hormone levels due to iodine deficiency feel fatigued, sluggish, and weak. These symptoms develop because thyroid hormones assist the body in producing energy.
When thyroid hormone levels are low, the body is unable to produce as much energy as normal. This may cause your energy levels to drop and leave you feeling exhausted. In fact, according to research of 2,456 participants, weariness and weakness were the most prevalent symptoms among those with low or somewhat low thyroid hormone levels.
