8 Signs and Symptoms of Iodine Deficiency

Your body needs an assortment of vitamins and minerals to function properly, including iodine. Iodine is a mineral that’s crucial for the production of thyroid hormones. Unfortunately, an estimated 35 to 45% of the world’s population is impacted by iodine deficiency. 

The sooner you can identify an iodine deficiency, the sooner you can start restoring your body’s levels of this essential mineral. 8 of the key signs and symptoms of iodine deficiency include:

Unexplained Weight Gain

Weight gain without another cause can point to an iodine deficiency. This occurs because the metabolism slows down without enough iodine, making it more likely that calories will be stored as fat. 

Swelling in The Neck

Many people with iodine deficiency experience swelling in the neck. This occurs when the thyroid gland becomes larger than usual, also known as goiter. 

Hair Loss

Hair loss can occur with iodine deficiency because thyroid hormones support healthy hair follicles. 


Iodine deficiency causes a decline in metabolic rate, which causes fatigue. A person with iodine deficiency may feel tired throughout the day despite getting enough rest. 

Dry Skin

Many people with iodine deficiency experience dry, flaky skin. This is a symptom of hypothyroidism, or an underactive thyroid. 

Feeling Cold

An iodine deficiency can cause your metabolism to slow down significantly. As a result, it won’t generate as much heat, and you may feel colder than usual. 

Heart Rate Changes

Without enough iodine, the heart may beat at a slower rate. In severe cases of iodine deficiency, an abnormally slow heart rate can lead to weakness, fatigue, dizziness, and even fainting. 

Memory Problems

Thyroid hormones are important for brain development. In some people, thyroid deficiency leads to challenges with learning and memory.
