Thyroid gland secretes hormone which plays a lot of important role in our body one important being to control metabolism. Hyperthyroidism is a condition in which our body secretes thyroid hormone more than reqiured. When the thyroid gland is overactive (hyperthyroidism) the body’s processes speed up and you may experience nervousness, anxiety, rapid heartbeat, hand tremor, excessive sweating, weight loss, and sleep problems, among other symptoms.
The symptoms of hyperthyroidism include the following:
- Fatigue or muscle weakness
- Hand tremors
- Mood swings
- Nervousness or anxiety
- Rapid heartbeat
- Heart palpitations or irregular heartbeat
- Skin dryness
- Trouble sleeping
- Weight loss
- Increased frequency of bowel movements
- Light periods or skipping periods
Some people may develop a goiter, which is an enlarged thyroid gland that feels like a swelling in the front of your neck
Contact your doctor if you think you may have symptoms of hyperthyroidism.
Hyperthyroidism is diagnosed based on symptoms, physical exam, and blood tests to measure levels of thyroid stimulating hormone (TSH) and thyroid hormones T3 and T4. Your doctor may also decide to order either an ultrasound or a nuclear medicine scan of your thyroid to see if it has nodules, or whether it is inflamed or overactive.
Treatment of Hyperthyroidism
Hyperthyroidism can be treated with antithyroid medications that interfere with the production of thyroid hormones (primarily methimazole; propylthiouracil is now used only for women in the first trimester of pregnancy). Another option is radioactive iodine therapy to damage the cells that make thyroid hormones. In rare cases in which women do not respond to or have side effects from these therapies, surgery to remove the thyroid (either one part of the entire gland) may be necessary. The choice of treatment will depend on the severity and underlying cause of your symptoms, your age, whether you are pregnant, other conditions you may have, and the potential side effects of the medication.
In addition to these treatments, your doctor may also prescribe beta-blockers to block the effects of thyroid hormones on your body. For example, beta-blockers help slow down a rapid heart rate and reduce hand tremors.
