The Thyroid is probably the most important gland in the human body. The proper functioning of the gland is crucial to kids. But, sometimes an underactive thyroid gland can lead to disorders and cause Hypothyroidism.

And, if you were looking for some information about Hypothyroidism, you’ve landed on the right page. Here, we talk about Hypothyroidism and how it affects children:

What Is A Thyroid?

Before we tell you more about Hypothyroidism, let’s give you an overview of the thyroid gland. The thyroid is a butterfly-shaped gland located in the neck. It is a ductless gland and secretes hormones that are essential for the following:

  • Proper growth and development of the body
  • Normal Heart Rate
  • To control body weight
  • To regulate the body temperature
  • The two most important hormones that the thyroid gland secretes include:
  • Thyroxine or T4
  • Triiodothyronine or T3

The thyroid acts as a thermostat for the body i.e. it maintains the normal temperature of the body. If it produces a larger amount of T3 and T4 hormones, then the body temperature rises. On the contrary, if it produces lower than the normal amount of hormones, then the body temperature dips.

What Is A Thyroid Disorder?

Sometimes, the thyroid gland does not function properly, and the hormone production is abnormal. In such a case, your kid may suffer from a Thyroid disorder. Thyroid disorders are usually of two types:

  • Hyperthyroidism
  • Hypothyroidism

What Is Hypothyroidism In Children?

Hypothyroidism is a disorder, in which the thyroid gland is underactive i.e. it doesn’t make enough hormones for the proper functioning of the body. Hypothyroidism is categorized as an endocrine disorder.

Causes Of Hypothyroidism In Children:

Hypothyroidism can develop due to a myriad of causes, and we list the major ones here:

1. Autoimmune Diseases:

Autoimmune diseases occur when the body starts producing antibodies against its tissues. As a result, the tissues of the body get destroyed. Although quite rare, it is a serious condition. The autoimmune reaction of the body produces antibodies that start destroying the thyroid gland. As a result, the child suffers from Hypothyroidism.

2. Radiation Therapy:

If your child was suffering from cancer in his upper body and opted for a radiation treatment for the same, then it is highly likely that he might develop Hypothyroidism after or during the treatment. Radiation treatments for cancer like Chemotherapy, cause permanent Hypothyroidism because such radiations affect the thyroid gland directly.

3. Thyroid Surgery:

If your child underwent a surgery wherein a large portion of his Thyroid gland was removed, then he is at a higher risk of developing Hypothyroidism. In such cases, the gland stops or lowers hormone production, which leads to permanent Hypothyroidism condition. The patient thus has to take thyroid hormones for his entire life.

4. Medications:

Many medicines can also cause Hypothyroidism. For instance, Lithium that is used to treat many psychiatric disorders, but it can lead to Hypothyroidism in some cases. Talk to your doctor about potentially harmful medications.

5. Hyperthyroidism Treatment:

This is probably the rarest cause of Hypothyroidism. But, kids with hyperthyroidism can also contract Hypothyroidism. As doctor use radio-active iodine and medicines to treat hyperthyroidism, it can damage the thyroid gland, and lead to permanent Hypothyroidism.
