What does the thyroid gland do?
The thyroid is a small gland in the front of the neck. It makes hormones that help regulate growth, energy use, body temperature, heart rate, bowel function, and development.
Thyroid problems can occur when the gland makes too little hormone, too much hormone, or becomes enlarged.
Hypothyroidism
Hypothyroidism means the body has too little thyroid hormone. Symptoms may develop slowly and can be mistaken for tiredness, school stress, or constipation.
- Tiredness, sleepiness, or low energy.
- Constipation, cold intolerance, dry skin, or hair changes.
- Slow growth or delayed puberty.
- Poor concentration or reduced school performance.
- Weight gain may occur, but it is not the only sign.
Hyperthyroidism
Hyperthyroidism means the body has too much thyroid hormone. It can affect the heart, mood, sleep, and growth.
- Weight loss despite good appetite.
- Fast heartbeat, palpitations, tremor, sweating, or heat intolerance.
- Irritability, anxiety, sleep difficulty, or school difficulties.
- Eye changes, such as prominent eyes, may occur in some conditions.
Goitre or neck swelling
A goitre is an enlarged thyroid gland. Parents may notice swelling at the front of the neck, tight collars, or a swelling that moves when the child swallows.
Neck swelling should be assessed by a doctor, especially if it is growing, painful, associated with breathing or swallowing difficulty, or accompanied by thyroid symptoms.
