I've been having my thyroid checked for about 12 months, having blood tests every 3 or 4 months. After the last one I got a call from my doctor's surgery saying I had to make an appointment to see the doctor; I don't know whether I have hypothyroidism or hyperthyroidism. I'm reluctant to take medication so have been researching online. I know there's a lot of rubbish out there as well as useful information. I read that you need selenium and zinc for a healthy thyroid gland, so am currently taking supplements. I want to give it a few months before I see the doctor. The thing is I only have a few of the symptoms for hyperthyroidism - tiredness, feeling the cold and while I don't have diarrhoea my stools have become softer and I often pass stools twice a day whereas previously I'd only ever passed a stool/stools once a day. As for feeling the cold, I've been like that since I was at least in my 30s (that's the first time I remember noticing it) and I'm 71 now. I'm not tired all the time but recently I feel tired more than I used to. My short memory has deteriorated, I put that down to age but I've always had a poor memory. Does anybody else just have 2 or 3 symptoms but is on medication?
