Can I just say that I was diagnosed with Graves disease just after I was married (at the time I was pleased that weight was peeling off) and became quite ill because the condition was so severe it started to affect my heart. My legs swelled up like elephant legs and I presented with a pulse of 140. I had no idea until my legs swelled that I was unwell and then it all kicked off and I was immediately sent for an ECG.
As soon as the bloods came back I was diagnosed and and the levels were severe with no hcg present (although the facts are a bit vague now). I was started straight away on carbimazole and beta blockers. I was in shock because all of a sudden I realised I wasn't invincible and how dare my body let me down. I can't say I felt that much better very quickly. Was diagnosed in May and initially was not happy with the first consultant or his attitude. I went back to the doctor and was referred privately to someone very eminent who reluctantly agreed with my reservations about having radioactive iodine due to wanting to start a family and referred me for a sub total thyroidectomy. I found information very hard to find in 1991 but after seeing a well known gynaecologist and obstetrician was convinced that I should seek to be in optimimum condition before conceiving and to give my future dc the best possible chances. This did not in my opinion involve either staying on radioactive iodine or carbimazole.
I had a successful sub total thyroidectomy and produced two fantastic babies (this was a bit of a struggle but I believe there is a growing body of research to indicate an increased miscarriage rate because thyroid disease is auto-immune).
Naturally I have been hypothyroid for over 20 years and have taken 100mcg of thyroxine in that time. I have had no problems whatsoever; I do not suffer from depression, I don't have weight problems (could do with losing a stone but that's due to too much food and alcohol rather than hormones). I do get some aches and pains but I'm 53. I also had a slightly early menopause which may be connected - may be not.
At the end of the day I have lived with my dodgy thyroid, I have made sure it is managed, I have not blamed it for anything in my life and I don't think my life or overall health has suffered much as a result. I take the tablet every night and just get on with it.
The most frustrating aspect has been ludicrous attitudes in GP surgeries around 28 day prescribing which has got better and difficulties accessing blood tests because they have been subcontracted to another surgery incapabable of making appointments for patients.
Just trying to impart the fact that it needn't be a big negative or have a big impact and it doesn't mean that lots and lots of other conditions arise as a result. It is entirely treatable and controllable and many of the "associated" symptoms one hears complained about have other causes and need to be dealt with separately rather be blamed on the thyroid. It doesn't make you fat, it doesn't make you depressed and in my experience it doesn't cause aches and pains - age and a propensity to inherited dodgy joints and what my gran called rheumatism do that.
