11 Signs of Iodine Deficiency That Should Be Considered

Iodine is an essential mineral for health. Iodine, a water-soluble mineral, is found in some foods and iodized table salt. It can also be taken as a dietary supplement. So, what are the symptoms of iodine deficiency, and is it dangerous?

Iodine is essential for growth and brain development and is central to healthy thyroid function. The thyroid gland uses iodine to make thyroid hormones.

Hypothyroidism occurs when a person’s thyroid cannot produce enough thyroid hormone. Iodine deficiency causes hypothyroidism by limiting the thyroid’s ability to produce hormones.

Symptoms of Iodine Deficiency


According to a study conducted in 2017, approximately one-third of people worldwide are iodine deficient. Here are 11 signs that you may have an iodine deficiency.

1.Weight Gain

Weight Gain

One of the most striking symptoms of iodine deficiency is unexpected weight gain.

When a person has a healthy metabolism, they burn calories for their energy needs. Hypothyroidism, or thyroid hormone deficiency, slows metabolism. When metabolism slows, calories are more likely to be stored as fat, which can lead to weight gain.

It is important to remember that weight gain is not always a symptom of iodine deficiency.

2.Feeling Powerless

Symptoms of iodine deficiency include feeling powerless. Heavy objects that were easily lifted in the past can strain the person. Hypothyroidism slows the metabolic rate. Thus, fewer calories are burned for energy. Less energy means the muscles are not working efficiently. This makes one feel powerless.
