Postpartum thyroidities

Hi,

I was admitted In emergency department with high high rate of 150 - 200 in jan 2015 and later diagnosed as hyper thyroid also called postpartum thyroidities ( my baby was born on oct 22nd 2014). So I was put on proponolol (beta blockers) to lower the heart rate and symptoms.

After 2 months I became hypo thyroid and was put on levothyroxine 50 mcg, since August 2015 I had symptoms of fatigue, dizziness, lightheadness, tremors, shaky hands and my heart rate was 110 with fluctuations in BP. I went to see a doctor but he said these symptoms are more related to Depression but I didn't believe him and later I went to another doctor he asked me to stop the levothyroxine for 3 days and asked me to go for blood test.

The blood results were given below.

Tsh - 3.78 (.30-5.60)
Vitamin b12 - 167  should be > 133
Ferritin 21 should be 11 -145

So, doctor suggested me to stop the levothyroxine as my tsh is in normal range and said because of 50 mcg I had developed the symptoms of high rate, fluctuations in BP, dizziness, fatigue.

It's been a week now since I stopped the levothyroxine 50 mcg but I still feel heart palpitations, fluctuation in BP and sometime dizziness. Please suggest me
how many days will it take go away the symptoms ?
Is it on stop the levothyroxine with above blood works.

Your doctor should be testing more than just TSH.  TSH is a pituitary hormone and an indirect measure of thyroid status.  He should also test FREE T3 and FREE T4, which are the actual thyroid hormones.  

It takes levo 4-6 weeks to be totally out of your system.  It's very important to follow up after about 4 weeks with another blood test to include FT3 and FT4.

B-12 is dismal.  You have to ask your doctor about supplementing that.  Be sure to follow up on this, too, as oral supplements will not work if you have pernicious anemia (the inability to absorb B-12 through the gut.  For proper thyroid health, ferritin should also be considerably higher in the range.

Medline Plus - Factitious hyperthyroidism...

"Definition
Factitious hyperthyroidism is higher than normal thyroid hormone levels that occur from taking too much thyroid hormone medication.

Treatment
You must stop taking thyroid hormone. If it is medically necessary, the dose must be reduced.

You should be re-evaluated in 2 - 4 weeks to be sure that the signs and symptoms of hyperthyroidism are gone. This also helps to confirm the diagnosis."

Medline Plus - Ferritin blood test...

"Normal value range is:

Male: 12-300 ng/mL (nanograms per millilter)
Female: 12-150 ng/mL

The lower the ferritin level, even within the "normal" range, the more likely it is that the patient does not have enough iron."

Peace with Endo - Could it be Vitamin B12 Deficiency?...

It is pretty simple to test for B12 through a serum blood test, however the authors pointed out different factors that can skew the results, making this test alone less reliable.

These factors include the presence of high levels of folate (or folic acid), which can make the complete blood count (CBC) test appear normal even though a B12 deficiency exists.

B12 serum testing can also show falsely elevated results for patients with underlying liver disease, alcoholism, lymphoma or intestinal bacteria overgrowth. And as mentioned above, pseudo vitamin B12 in spirulina, temph and nori can throw off blood tests results.

According to the authors, the range of “normal” B12 levels is traditionally set too low. They suggest raising the minimum from 200 pg/ml to at least 450 pg/ml, since deficiencies start to appear below 550 pg/ml.

Since the threshold of “normal” is set too low by doctors, the authors suggest implementing a couple of more tests to make sure there is in fact a deficiency. These include a urinary Methylmalonic Acid test (MMA) and testing for homocysteine (Hcy) levels. When you are low in B12 the three lab results should agree with one another:

Serum B12 is low
MMA is elevated
Hcy is elevated

The authors recommend supplementing with B12 if your serum B12 levels are under 450 pg/ml, regardless of what MMA or Hcy results are. Also, treat normal B12 serum but elevated MMA or Hcy results. The book gives further breakdown on what the ranges should be for each test."
