B12 and ferritin levels

[Beaniemadbecky]

Hi everyone just come off the phone to GP who's asked me to put some information together regarding low vitamin levels and my continued hypothyroidism symptoms. I had low vitamin D,B13 and ferritin levels. I've managed to highten my vit D levels through self supplementing. However, my B12 and ferritin won't budge. Can ever one on here state why these vitamin levels are important to them and their personal experiences so I can print n send to my GP. Tia

Do you have the results and reference ranges for the nutrient testing you've had done?

It's very difficult to comment in a vacuum.

When hypothyroid many/most patients develop low stomach acid, this frequently results in low vitamin levels.

Food intolerances are common too

NHS England Liothyronine guidelines July 2019 clearly state on page 13 that TSH should be between 0.4-1.5 when treated with just Levothyroxine

Note that it says test should be in morning BEFORE taking Levo thyroxine

Also to test vitamin D, folate, B12 and ferritin

sps.nhs.uk/wp-content/uploa...

Guidelines on levothyroxine dose by weight.....Aim is to bring TSH to at least under 2.5

Vitamin D

ncbi.nlm.nih.gov/pubmed/286...

Vitamin D deficiency is frequent in Hashimoto's thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

endocrine-abstracts.org/ea/...

Evidence of a link between increased level of antithyroid antibodies in hypothyroid patients with HT and 25OHD3 deficiency may suggest that this group is particularly prone to the vitamin D deficiency and can benefit from its alignment.

ncbi.nlm.nih.gov/pubmed/300...

ncbi.nlm.nih.gov/pmc/articl...

Our results indicated that patients with hypothyroidism suffered from hypovitaminosis D with hypocalcaemia that is significantly associated with the degree and severity of the hypothyroidism. That encourages the advisability of vit D supplementation and recommends the screening for Vitamin D deficiency and serum calcium levels for all hypothyroid patients.

Low B12 - extremely common in hypothyroid patients

All patients who are hypothyroid should have B12 tested

ncbi.nlm.nih.gov/pubmed/186...

There is a high (approx 40%) prevalence of B12 deficiency in hypothyroid patients. Traditional symptoms are not a good guide to determining presence of B12 deficiency. Screening for vitamin B12 levels should be undertaken in all hypothyroid patients, irrespective of their thyroid antibody status. Replacement of B12 leads to improvement in symptoms,

ncbi.nlm.nih.gov/pubmed/169...

Patients with AITD have a high prevalence of B12 deficiency and particularly of pernicious anemia. The evaluation of B12 deficiency can be simplified by measuring fasting serum gastrin and, if elevated, referring the patient for gastroscopy.

Folate supplements can help lower homocysteine

ncbi.nlm.nih.gov/pmc/articl...

Levothyroxine can decrease serum homocysteine level partly; still its combination with folic acid empowers the effect. Combination therapy declines serum homocysteine level more successfully.

Low ferritin frequent in hypothyroidism

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Coeliac

ncbi.nlm.nih.gov/pmc/articl...

Among autoimmune disorders, increased prevalence of CD has been found in patients with autoimmune thyroid disease, ..........., 2% to 5% in autoimmune thyroid disorders ......in prospective studies. …..Screening high risk patients for CD, such as those with autoimmune diseases, is a reasonable strategy given the increased prevalence.

sciencedirect.com/science/a...

Screening for celiac disease in patients with hypothyroidism requiring elevated levothyroxine doses warrants further investigation.

Non Coeliac Gluten sensitivity (NCGS) and autoimmune disease

ncbi.nlm.nih.gov/pubmed/296...

The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported

ncbi.nlm.nih.gov/pubmed/300...

The obtained results suggest that the gluten-free diet may bring clinical benefits to women with autoimmune thyroid disease

nuclmed.gr/wp/wp-content/up...

In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned

restartmed.com/hashimotos-g...

Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.

88% benefit from strictly gluten free diet

thyroidpharmacist.com/artic...

Going gluten free is a strategy that everyone with Hashimoto’s should try. In some cases, we see a complete remission of the condition; in other cases (88% of the time), the person feels significantly better in terms of bloating, diarrhea, energy, weight, constipation, stomach pain, reflux, hair regrowth, and anxiety.

todaysdietitian.com/newarch...

Many clinicians report that eating a gluten-free diet may help improve thyroid function in nonceliac gluten intolerance. “Getting gluten out is primary for patients with Hashimoto’s, even without celiac disease,”

Lactose intolerance

Lactose intolerance is also very common with Hashimoto's

ncbi.nlm.nih.gov/pubmed/240...

Lactose intolerance was diagnosed in 75.9 % of the patients with HT

These findings show that lactose intolerance significantly increased the need for oral T4 in hypothyroid patients.
