> Thyroid problems can affect children too — congenital hypothyroidism, autoimmune disease and the importance of early diagnosis.

Thyroid disorders are often thought of as adult conditions, but children can be affected too — from congenital hypothyroidism present at birth to autoimmune thyroid disease developing later in childhood.

## Congenital hypothyroidism

Congenital hypothyroidism is present at birth and affects approximately 1 in 3,000–4,000 newborns. It occurs when the thyroid gland is absent, underdeveloped, or unable to produce enough hormone.

**Why it matters:** Thyroid hormone is essential for brain development in infancy. Untreated congenital hypothyroidism can lead to intellectual disability and developmental delays. This is why most countries — including Nepal — screen newborns for thyroid function shortly after birth.

**Treatment:** Lifelong levothyroxine, started as early as possible, usually produces normal development if begun within the first weeks of life.

## Autoimmune thyroid disease in children

Hashimoto's thyroiditis and Graves' disease can develop in childhood and adolescence, particularly during puberty.

**Hashimoto's** is the most common cause of hypothyroidism in children. Symptoms may include fatigue, weight gain, constipation, dry skin, hair thinning, and poor growth or delayed puberty.

**Graves' disease** causes hyperthyroidism and may present with weight loss, increased appetite, rapid heartbeat, tremor, anxiety, and in some cases, eye changes.

## How thyroid disease affects growth and development

Thyroid hormone is critical for normal growth and brain development. In children, untreated hypothyroidism can cause:

- Slowed growth and short stature
- Delayed bone age
- Poor school performance and concentration
- Delayed puberty

Early diagnosis and treatment with levothyroxine usually allow normal growth and development to resume.

## When to suspect thyroid problems in children

Consider thyroid testing if your child has:

- Unexplained fatigue or sluggishness
- Weight gain or difficulty gaining weight
- Constipation or dry skin
- Hair thinning or brittle hair
- Delayed growth or puberty
- Irregular periods (in adolescent girls)
- Rapid heartbeat, tremor, or anxiety (possible hyperthyroidism)

## The bottom line

Thyroid disorders in children are treatable, but early diagnosis is essential for normal growth and development. If you suspect thyroid problems in your child, consult a paediatrician or endocrinologist promptly.
