Importance of Iodine in your Child’s Diet

Our body demands us to take certain minerals through our diet to maintain a healthy lifestyle. It is important to understand that each mineral has its own role in the functioning of the body. Iodine is one such essential mineral that goes into the body only by the food we consume. Researches prove that an adult must have 50ug/day of iodine to prevent deficiency in the body.

The best sources of iodine are fish, eggs, nuts, table salt and dairy products. At times people fail to enrich the body with a minimum dose of iodine leading to iodine deficiency in the body. Iodine is in direct connection to the thyroid gland as the chemical components of iodine stimulate the thyroxin hormone that controls major functions of the body.

Iodine is not naturally produced in the body, therefore, the only way to ingest it is through what we eat. Deficiency of iodine is a growing problem in multiple countries and more than 2 billion people suffer from iodine deficiency. It is important to note that pregnant women need more iodine than an average adult.

Iodine Deficiency in Children: Symptoms and Treatment

11 Iodine Deficiency Symptoms in Children

The major symptoms of iodine deficiency are;


Goiter is one of the most common symptoms of iodine deficiency that leads to swelling in the neck. It leads to inflammation in the butterfly-shaped thyroid gland responsible for the production of the thyroid hormone in the body. When the body detects an excess of TSH the thyroid gland secretes hormones to regulate the production in the blood but an iodine deficiency leads to malfunctioning in the thyroid gland. To recompense, the thyroid gland works harder leading to growth and swelling in the gland known as goiter. Though the majority of the cases can be treated yet it can cause permanent damage to the thyroid gland.

Unanticipated weight gain

The thyroid hormone controls the rate of metabolism in the body and maintains body weight. Low level of thyroid hormone in the blood does not stimulate the body to break down calories. This causing low metabolic rate and storage of fat in the body. Deficiency of iodine in the body leads to unchecked weight gain causing obesity. Obesity in itself breeds multiple diseases and increases the risk of diabetes in patients.

Hair loss

The thyroid hormone controls the generation of hair follicles. When the thyroid hormones are absent in the body it leads to slow regeneration of hair follicles. Over time the growth of new hair cannot match with the speed of hair fall, leading to excess hair loss and mild baldness in many patients. Proper addition of iodine may help replenish the thyroid hormone and fight the deficiency symptoms.

Fatigue and weakness

Studies prove that nearly 80% of iodine deficient victims feel lethargic and sluggish throughout the day. There working capacity is much lower than an average human being. This is because iodine deficiency in the body does not stimulate the thyroid hormone which is responsible for speedy metabolism and regulated energy rates in the body.

Dry and wrinkly skin

People who suffer from an iodine deficiency have dry and flaky skin. The skin cells that need constant regeneration are controlled by the thyroid gland of the body. It also controls the sweat gland of the body. People with low iodine concentrate have less amount of sweating in the body. Sweating not only keeps the skin moist but also removes unwanted liquid waste from the body. This makes the skin dry and flaky.

Change in heart rate

When one refers to the heart rate of a person it means per minute cycle of the heart. If a person has low levels of iodine in the body his heart rate tends to be slower than normal and vice versa. At time severe iodine deficiency leads to abnormally low heart rate which increases the risk of heart diseases, fatigue and dizziness in the body.

Experiencing unusual cold

People with low iodine levels in the body feel colder than any other healthy individual. It is important to note that just like the thyroid hormone is responsible for a speedy metabolism in the body. Due to iodine deficiency, the body is unable to break down food to release the stored energy, the patient feels colder than others due to lack of body energy.

Trouble memorizing things

It is essential to understand that an iodine deficiency can disrupt the overall working of the body. The thyroid gland responsible for the generation and regeneration of body cells fails to match up with the body’s growth. Thyroid hormone helps the brain grow but the absence of it leads to slow brain development and low memorizing skills.
