All about Hypothyroidism (Part 3): What are the types of Hypothyroidism?

Updated: Mar 2

Types of Hypothyroidism

1. Juvenile /pediatric/ congenital / Transient hypothyroid

At birth, there are two forms of hypothyroidism.

Transient hypothyroidism is characterized by abnormal thyroid hormone levels during birth as a result of the mother’s thyroid medication or antibodies. It normally clears up on its own and does not require long-term therapy.

Congenital hypothyroidism is a condition that is present at birth and can be detected through neonatal screening. This type can lead to mental retardation if not treated.

Children’s hypothyroidism symptoms differ from those of adults. Each youngster may have a different set of symptoms–or none at all. The following are the most prevalent symptoms, organised by age:

  1. Newborns – Jaundice (a yellowish hue to the skin), constipation, and diarrhoea are common among newborns.

  2. Children – slow growth

  3. Teenagers – delayed puberty

  4. Acquired hypothyroid

Atrophy of thyroid gland; Antibody attack causes atrophic thyroiditis, a severe form of primary hypothyroidism in which the thyroid gland shrinks and shrivels.

  • Induced hypothyroid (Amiodarone induced)

Hypothyroidism is a potential side effect of Amiodarone, an antiarrhythmic drug.

  • Pregnancy induced/ maternal hypothyroid

Hypothyroidism in pregnant women is known as maternal hypothyroidism. It may offer risks not only to the mother, but also to the unborn, and needs appropriate treatment.

Another classification of Hypothyroidism is

  • Primary hypothyroid –

In this type, the thyroid gland is sufficiently activated. The thyroid gland, on the other hand, is unable to create enough thyroid hormones for the body to function properly. This indicates that the problem is caused by the thyroid gland.

  • Secondary Hypothyroidism
