Hello, I have recently been diagnosed with complex cysts in my left thyroid a couple of months ago.. I see the endocrinologist on the 24th of this month... The past couple of months, I have had a decrease in appetite, weight loss of 20 pounds, watery stools, and the feeling of fullness half way through eating something... My primary says that it is not hyperthyroidism because my levels were normal in January of this year... Is it possible that it is hyper at this time?? Or what else could it be??? has me a little worried.. I see my primary tomorrow for this problem.. Thank you
