My Wife had her Thyroid removed about 10 years ago, she has been on Levothyroxine and seems to be very stable. However she has developed alergies that seem to be getting worse. She can't touch, chocloate, cheese, sugar, alcohol. She also seems to be getting worse in the summer with Pollen etc. Is this a common side effect of Thyroid removal and can she do any thing other than avoid these. She is on daily anti alergy tablets.
