hi my poor daughter was diagnosed with graves disease over a year ago. it took a year to get her levels from hyper to hypo. now her levels are slightly increasing so endo has increased carbimozale to 30mg and keeping her on 25mcg levo. of late she is holding her urine for too long. she went at 7.30pm night before last then didnt go until 2.45 pm the following day. it is not down to lack of drinking as she drinks a lot during the day. has anyone experienced this problem. her colour on her face is very pale also. the endo said her toileting is down to behaviourial issues but there is no way. it cant be doing her any good holding her urine for this long.
