Tummy ache

Liza283 profile image

I was diagnosed with overactive thyroid last november. I was put on 15mg carbimazole. Subsequently with blood lests it was then decreased to 5 mg. Then in October I had my first hospital appointment and the Consultant said to stop the carbimazole. So I've stopped it and the ranitidine which I was taking for bad heartburn. Over the last week or so I've found I'M having heartburn again and feeling quite nauseas on occasion- Is this all due to coming off the tablets or something else or thyroid going back up?

Can you post your test results and ranges

Thyroid tests plus - TSH, FT4, FT3 plus thyroid antibodies, TPO and TG antibodies, plus if you have them, vitamin D, folate, ferritin and B12

Yes the heartburn is likely due to stopping the ranitidine. But it may be you actually had low stomach acid not high stomach acid

Many of us with thyroid issues have LOW stomach acid. Same or virtually identical symptoms, very different treatments



Lots of posts on here about how to improve with Apple cider vinegar or Betaine HCL

hi, thanks for responding. I dont have any of that information sorry. I'm not really given any information other than blood test forms to have done at 6 week intervals. Back at the hospital in 3 months.

You are entitled to copies of your own blood test results.

Really good idea to keep good records of how you felt when on which medication and what blood test results were

You can ring reception at GP's and ask for copies. It takes a day or two to organise and they may make nominal charge for printing out


It's probably stopping the Ranitidine which has caused the heartburn and nausea. Try taking Ranitidine as and when required to see whether it improves.

Touch wood ive taken one today, and I'm not feeling so queasy.

Nausea usually happens because of overactive thyroid.carbimazole adjusting will give comfort.its always good to check the thyroid levels when ever you feel bad.
