Hi Rita,
Your elevated TSI confirms that you have active Graves' disease. Some eye symptoms are caused by high levels of thyroid hormone. A more serious type of TED is autoimmune and caused by TSI and blocking TSH receptor antibodies. Most people do not get this autoimmune form of TED.
Problems with sleeping and bloating can be caused by thyroid hormone levels (FT4 and FT3) that are within range but too low for your body's needs. These symptoms are usually seen in hypothyroidism although there are many other causes including imbalances of other hormones, food allergies, etc. Best, Elaine
