PORT ST. LUCIE, Fla. - The Mets announced last night that tests on Jose Reyes have confirmed he has an overactive thyroid and he will remain in New York "to await additional blood tests that will help further determine his treatment."
Reyes said he was told before he returned to New York on Thursday that his thyroid levels from two previous tests in Florida showed that he was "over," meaning that he could have hyperthyroidism. Treatment ranges from medication for the simpler cases to surgery for the removal of the thyroid in the more extreme.
The Mets said last night they did not expect the results of the additional testing before Thursday and there is no timetable yet for a return.
Reyes, 26, said last week that he had no previous history of thyroid problems and was not experiencing any symptoms, such as weight loss, excessive perspiration or heart palpitations. But the Mets' doctors did not want Reyes on the field. Left untreated, hyperthyroidism could cause an irregular heartbeat, especially during exercise, which is the reason Reyes has been prohibited from any physical activity - even riding a stationary bike.
Dr. Andrew Martorella, a thyroid specialist who practices at Weill Cornell Medical College in Manhattan, told Newsday last week that Reyes' condition is "really a very common thing, very treatable and completely curable."
He said there are a number of causes, such as a cold or flu virus, or a type of autoimmune reaction. In some cases, the overactive thyroid simply returns to normal on its own. In others, it is treated with medication, such as the drug Tapazole or radioactive iodine, to bring the thyroid back under control.
