The symptoms of hyperthyroidism can be varied and affect multiple systems in the body. Common indicators include rapid heartbeat, weight loss despite normal or increased appetite, nervousness, anxiety, and muscle tremors. Many individuals also report excessive sweating, heat intolerance, and changes in bowel habits, such as more frequent bowel movements or diarrhea. In women, hyperthyroidism can cause menstrual irregularities, including lighter or less frequent periods. A visible enlargement of the thyroid gland, known as a goiter, may develop in some cases, causing a noticeable swelling at the front of the neck.
Several conditions can trigger hyperthyroidism, with Graves’ disease being the most common cause. Graves' disease is an autoimmune disorder in which the body's immune system mistakenly targets the thyroid, leading to overproduction of thyroid hormones. Toxic nodular goiter, another cause, involves the development of lumps or nodules in the thyroid that function autonomously, producing excess hormones. Additionally, thyroiditis, an inflammation of the thyroid gland, can also result in temporary hyperthyroidism.
Treatment for hyperthyroidism depends on the severity of the condition and its underlying cause. Common interventions include antithyroid medications, which help reduce hormone production, and radioactive iodine therapy, which shrinks the overactive thyroid cells. In some cases, beta-blockers are prescribed to manage symptoms such as rapid heartbeat and tremors. If other treatments are ineffective or inappropriate, surgery may be recommended to remove part or all of the thyroid gland. Accurate diagnosis and proper management are essential to avoid complications such as heart problems, osteoporosis, and, in rare cases, a life-threatening condition known as thyroid storm.
