Changes in menstrual cycles. Increased sensitivity to heat. Changes in bowel patterns, especially more-frequent bowel movements. Enlarged thyroid gland, sometimes called a goiter, which may appear as a swelling at the base of the neck. Tiredness. Muscle weakness. Sleep problems. Warm, moist skin. Thinning skin. Fine, brittle hair.

  Hyperthyroidism happens when a child’s thyroid gland makes more thyroid hormone than they need. The thyroid gland is butterfly-shaped and is located in the neck, just below the Adam’s apple. Its job is to release thyroid hormone into the blood to control the body’s heart rate, temperature and metabolism. An overactive thyroid gland can get big and it may look and feel like a lump in the throat, especially when the child swallows. […] When the thyroid gland releases too much hormone, this speeds up a child’s metabolism and causes problems such as anxiousness, weight loss and tremors. It can also affect their growth and development. However, pediatric hyperthyroidism is treatable and is rare compared to hypothyroidism. […] Treatment is important because hyperthyroidism can cause cognitive delay in children under 3 years old, which affects their ability to think and learn. In newborns, it can be life-threatening if it isn’t diagnosed soon after birth. Untreated hyperthyroidism can also cause children to grow quickly at first, and then stop growing early. This can cause short stature.

[…] Patients with hyperthyroidism will usually have a low TSH and a higher than normal T4 and/or T3 level. […] If the thyroid is overactive, the RAI scan will determine if the whole gland is hyperactive as in Graves’ disease or just certain areas as in toxic multinodular goiter, or if just one area is hyperactive as in a toxic nodule. […] Hyperthyroidism may be treated with medications (anti-thyroid medications), radioactive iodine ablation (RAI ablation), removal of the thyroid gland (hemithyroidectomy or total thyroidectomy). […] Most patients go on to have a more definitive therapy such as RAI ablation or surgery. […] Regardless of whether the patient has RAI ablation or surgery, the goal of both treatments is to make the patient hypothyroid (i.e. not make enough thyroid hormone).

  Thyroid storm (or thyrotoxic crisis) is a serious complication of hyperthyroidism. It occurs when a child’s thyroid hormone levels become severely elevated. Although thyroid storm is rare, it can be life threatening. The most important symptoms of thyroid storm are a high temperature or changes in mental status (like confusion or lethargy). If you suspect your child may be experiencing thyroid storm, you should always seek immediate medical care. […] Hyperthyroidism caused by thyroiditis is usually temporary and goes away within eight to 12 weeks. Because we cannot make this hyperthyroidism go away any faster, treatment focuses on medications to control any symptoms (like palpitations and anxiety) until the condition goes away on its own. Sometimes, this type of hyperthyroidism is followed by a period of hypothyroidism (low thyroid function), so continued monitoring by a physician is important.

  Due to increased pumping of the heart, a person with hyperthyroidism will often notice their heart racing or bounding. Irregular heart rhythms (called arrhythmias) and high blood pressure may also occur with an overactive thyroid gland. […] Weight loss, despite an increase in appetite, is due to both the increase in gut mobility (which leads to fat malabsorption) and metabolic rate (which means the body is burning through calories quicker than normal). While this increase in metabolism may initially energize people, eventually they become fatigued as the body tires out. […] An enlargement of the thyroid gland (called a goiter) may occur in some people with hyperthyroidism, causing potential symptoms like a sore throat and/or neck discomfort.

  The thyroid is one of the few organs in the body that avidly takes up iodine. This allows radioactive iodine to selectively damage the thyroid gland without affecting other parts of the body. The thyroid gland is eventually destroyed and disappears and the body no longer produces its own thyroid hormone. In general, this treatment can be used in patients with Graves’ disease or in those patients with nodules in the thyroid gland causing hyperthyroidism. Not all cases of hyperthyroidism respond well to radioactive iodine.
