Recently diagnosed with over active thyroid

For some time I had been unwell and GP organised various tests to try to diagnose the problem. From the blood test he identified I had over active thyroid.

He prescribed 20mg carbimazole and an urgent appointment with consultant. Three weeks later I have heard from the consultant by letter to confirm that he confirms GP has put me on right medication , I will be having a MRI and see him in due course.

I am feeling slightly better now after 3 weeks on tablets. But today I have a very sore throat rang GP for advise and I was advised to stop medication and to have a blood test in the morning to check white cells. I am now quite panicky about sure throat and stopping medication....

That's standard advice if you're on carb. However, the chances are you just have a bog standard sore throat and you'll be back on the meds very shortly and feeling fine. Try not to worry about it.


Trust your GP, he's looking after you well and is making sure your sore throat isn't a precursor to thyroid storm which is a medical emergency.

Ask whether he will test your ferritin, vitamin D, B12 and folate as you're having blood draw tomorrow. Having these high in range can make a beneficial difference to well being and ability to fight infection.

Make sure to ask for a print out of all blood tests with laboratory ref ranges so you can monitor your own thyroid health and post here if you have questions.

i hope all's well tomorrow.

They will test your white blood cells. Carbimazole can affect them. If the sore throat is caused by the carb they can try you with PTU - if it isn't the carb causing the problem then your GP will probably say to go back onto the carb.

I had one blood test not long after I started my carb but it was fine. I felt ok and I didn't have mouth ulcers dr anything other than the throat / swollen glands but it was coming up to a long holiday and I wasn't sure about 'waiting and seeing'

I know it is difficult but try not to worry too much.

I would like to say a big thank you for your support last week.

I had a blood test, and it showed that my white cells had gone up slightly since last test but still within the normal range. My sore throat disappeared after a few days. Now back on medication. I have been on carbimazole for 4 weeks now and I feel so much better. I am now back to work, heart pounding, panic attacks and lack of confidence has gone . I have a MRI on the thyroid soon followed by an appointment with the consultant.
