if your thyroid gland makes too much thyroid hormone you will have symptoms of hyperthyroidism. most hyperthyroidism is caused by an immune system problem called graves' disease. at first your hyperthyroidism may make you feel hot have tremors in your hands or lose weight. over time you may notice that your heart is beating fast that you feel anxious or that you are having a lot of bowel movements. you may also feel like you just don't have as much energy as usual. hyperthyroidism generally does not go away on its own. most people need treatment to make hyperthyroidism go away. after treatment many people develop hypothyroidism (too little thyroid hormone). in rare cases hyperthyroidism can cause a life-threatening condition called thyroid storm which occurs when the thyroid gland releases large amounts of thyroid hormones in a short period of time. webmd medical reference from healthwise this information is not intended to replace the advice of a doctor. healthwise disclaims any liability for the decisions you make based on this information. © 1995-2011 healthwise incorporated. healthwise healthwise for every health decision and the healthwise logo are trademarks of healthwise incorporated.
