Susan asked...

I was diagnosed with pernicious anaemia.

I was diagnosed with pernicious anaemia about 30 years ago and have a B12 injection every 3 months and have suffered no side affects. More recently (approx. 4 years) I was diagnose with an underactive thyroid and am taking 100mcg Levothyroxine per day. In the last 3 years I have lost confidence particularly with driving and taking my normal solo holidays abroad. More recently I have become concerned about my memory - I would really appreciate any information regarding the side effects of these autoimmune diseases and whether there is any other medication I can take.

    Do you need to see a GP quickly?


    Would you like to speak with a doctor by video or phone at a time that suits you?

    Our Doctor@Hand service, delivered by Doctor Care Anywhere, offers a doctor appointment by video or phone at a time that suits you.

The answer

The pernicious anaemia and hypothyroidism have both been treated so you are not at risk of developing side effects from these autoimmune diseases. You would only get side effects if they had been left untreated, so do not worry about that. The only treatment for them is the replacement of the hormones or vitamins that you are lacking, which you are already taking anyway. It sounds like the loss of confidence and concerns about your memory are a separate issue.

I would like to suggest that you make an appointment with your doctor to discuss these things in more detail. You could have a routine blood test to check and make sure everything is in order, along with a memory test.
