Iodine deficiency can go unnoticed for a long time, but the body often sends quite obvious signals. The endocrinologist explained what changes in appearance and well-being should be paid special attention to.

Iodine plays a crucial role in the functioning of the thyroid gland, and its deficiency can affect almost the entire body. According to endocrinologist Liberanskaya, there are signs of iodine deficiency that can be noticed even without medical examinations.

Swelling of the face and body

One of the most common symptoms of iodine deficiency is morning swelling.

Most often, it appears under the eyes, but the hands and feet can also swell. Such changes become particularly noticeable to those around and may indicate thyroid dysfunction.

Hair and eyebrow loss

With a lack of iodine, the function of the thyroid gland suffers, which can lead to the development of hypothyroidism.

Against this background, hair loss often begins, as well as thinning of the outer part of the eyebrows — this is considered one of the characteristic signs of the problem.

Hormonal imbalances

In women, iodine deficiency may be accompanied by menstrual cycle disturbances and the development of mastopathy.

In men, there may be a decrease in testosterone levels and problems with the prostate gland. In the presence of such symptoms, specialists recommend consulting a doctor.

Constant weakness and drowsiness

Many people with iodine deficiency complain of lethargy, quick fatigue, and lack of energy.

As the endocrinologist explains, this is related to a decrease in the levels of thyroid hormones, which are responsible, among other things, for energy metabolism.

Memory and concentration problems

Another alarming symptom is the deterioration of cognitive functions.

A person finds it more difficult to concentrate, remember information, solve complex tasks, and engage in creative activities.

Apathy and mood deterioration

With iodine deficiency, emotional states can also change.

Apathy, passivity, depression, and a tendency to perceive events negatively may arise. In some cases, such a state can develop into severe depression.

According to the editorial team, many symptoms of iodine deficiency can easily be confused with ordinary fatigue or stress. However, if several signs persist for a long time, it is better not to postpone a visit to the doctor and check the condition of the thyroid gland.
