Daughter's Blood Results advice


My daughter has just received her blood results. She has Hypothyroidism, Pernicious Anaemia, and has just had a test result back saying she has Inflammatory bowel disease, namely Crohn's or non specific ileitis. She will be seeing a Gastro consultant very soon for more investigations. Apart from her acid/bloated stomach symptoms, her other symptoms are: fatigue, weight gain, brain fog, breathless, painful swollen eyes, cold, feeling down. She is taking 150 thyroxine daily and B12 injection 3 months.

TSH 2.38 (0.27-4.2)

Free Thyroixine 21.8 (0.27-4.2)

Active B12 - 78 (25.1-165)

Folate 5.9 (4.6-18.7)

Iron 23.2 (6.6 - 26.0)

Vit D 49 (50-200)

What is the best Vit D supplement I should buy and how much a day would you recommend to raise her levels.

I have asked her Dr to give her a B12 injection every 2 months instead of 3, they will not allow. Should she take a B12 by mouth in between injections?

She has tried taking 175 of thyroxine, however this make her hyper?

She has very high Thyroid antibodies - 1000

I am presuming as she has just been diagnosed with IBD her Pernicious Anaemia has something to do with it?

I look forward to hearing from you ...... your advice is so much appreciated. :)

Deb59, you've repeated the TSH range for your daughter's FT4 range. Did she feel hyper on 175mcg or did blood results say she was overmedicated?

TSH 2.38 is rather high for someone on Levothyroxine. Most people feel euthyroid when TSH is just under 1.0. FT4 21.8 is usually top of the range but can be slightly over range to reduce TSH which can be helpful in reducing Hashi flares and antibodies. Read Treatment Options in Email if you would like a copy of the Pulse article to show your daughter's GP.

The best way to reduce Hashi flares and antibodies is to adopt 100% gluten free diet and your daughter may find this helpful in managing her IBD too.

Active B12 >35 means there is unlikely to be B12 deficiency but if your daughter feels run down in between B12 injections she can supplement methylcobalamin sublingual lozenges, spray or patches. 5000mcg is available on Amazon.

Folate is low in range so supplementing a B Complex vitamin will boost it a little and helps keep the other B vits balanced while she is having injections and supplementing.

I prefer D3 softgel capsules to tablets but spray and drops are also available. I suggest 5,000iu daily for 8 weeks and then reduce to 5,000iu alternate days. Again, Amazon is a good source.

Thank You Clutter.... Will follow your advice. I love this site! Who needs a doctor! 😀


Consider having a test to exclude celiac disease before going gluten free.


Yes I will, thank you.
