Need advice - blood test results

*21(F), weight = 40kg, height = 5ft1*

I've been feeling quite awful the past two months and symptoms haven't been improving. I've been experiencing extreme fatigue (much worse than the way I felt before having been diagnosed with hypothyroidism), light headedness, weakness and daily nausea. I've been taking omeprazole to help with my reflux symptoms but it has done nothing for me. I've done lots of blood tests this month and don't seem to be getting any answers.

April 1st:

Serum folate = 2.0ug/l (normal range: 3.1 - 20.5) - I've been taking folic acid for three weeks now and feel no different.

Serum vitamin B12 = 499ng/l (normal range: 187 - 883) - normal

Serum ferritin = 37ug/l (normal range: 22 - 275) - normal

Renal profile, liver function, bone profile, ESR and full blood count were all normal.

April 22nd (hormones):

Serum TSH: 1.46 mlU/L (normal range: 0.27 - 4.20) - normal

Serum testosterone = 4.1nmol/L (normal range: 0.0 - 1.8) - abnormal

Serum LH = 15.1 IU/L (normal range: 2.4 - 12.6) - abnormal

Serum FSH = 7.7 IU/L (normal range: 3.5 - 12.5) - normal

Serum prolactin = 620 mlU/L (normal range: 102 - 496) - abnormal

I want to add, I did the second set of blood test on the 22nd early in the morning before taking my 25mg levothyroxine. I've also had a pelvic ultrasound which didn't show any cysts on my ovaries so it's definitely not PCOS. Also, I stopped taking the progesterone only birth control pill on the 1st of February, and waited two months and three weeks before getting my sex hormones checked (I've had two periods since coming off the pill, one in march and another one this month). My testosterone level was also abnormal in October 2020, but it wasn't as high as it is now.

I'm just really confused and would love some advice/insight into what could be going on. Sorry for rambling!

If you want the full picture on your thyroid you need to get your t4 and T3 tested (T3 rarely done by nhs). I'd get them done privately via eg Medichecks (25% off today I saw) but there are many others... then post your results along with the ranges. What was your tsh pre diagnosis?

I've seen many say 25mcg often just makes your body feel worse and that it's not the correct starter dose (see NICE guidelines). Others will comment.

Standard starter dose of levothyroxine is 50mcg

Levothyroxine doesn’t top up failing thyroid, it replaces it

Guidelines on dose by weight is approx 1.6mcg levothyroxine per kilo

As you are extremely petite, you’re likely to not need too many increases

40kilo is likely to need 64mcg levothyroxine per day....but initially starting on 50mcg

Some people find they need high dose of levothyroxine than guidelines

guidelines on dose levothyroxine by weight

Even if we frequently don’t start on full replacement dose, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or near full replacement dose

NICE guidelines on full replacement dose

nice.org.uk/guidance/ng145/...

1.3.6

Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.

Also here

cks.nice.org.uk/topics/hypo...

gp-update.co.uk/Latest-Upda...

Traditionally we have tended to start patients on a low dose of levothyroxine and titrate it up over a period of months. RCT evidence suggests that for the majority of patients this is not necessary and may waste resources.

For patients aged >60y or with ischaemic heart disease, start levothyroxine at 25–50μg daily and titrate up every 3 to 6 weeks as tolerated.

For ALL other patients start at full replacement dose. For most this will equate to 1.6 μg/kg/day (approximately 100μg for a 60kg woman and 125μg for a 75kg man).

If you are starting treatment for subclinical hypothyroidism, this article advises starting at a dose close to the full treatment dose on the basis that it is difficult to assess symptom response unless a therapeutic dose has been trialled.

BMJ also clear on dose required

Many thyroid patients have LOW stomach acid.

Omeprazole is for high stomach acid

Low stomach acid can be a very common hypothyroid issue

You also need vitamin D tested

Test twice yearly via NHS

vitamindtest.org.uk

Folate is obviously deficient

Once you finish prescribed folic acid

supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid

chriskresser.com/folate-vs-...

B vitamins best taken after breakfast

Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)

Or Thorne Basic B is another option that contain folate, but is large capsule

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

Low ferritin

Look at increasing iron rich foods in diet

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

Great in-depth article on low ferritin

oatext.com/iron-deficiency-...

drhedberg.com/ferritin-hypo...

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.

Thyroid disease is as much about optimising vitamins as thyroid hormones
