Can thyroxine make you gain weight?

47 Replies

Hi all,

I've been battling hypo issues for more than 20 years. So much so that my doc (and a specialist) thought i didn't need medication and was off meds for more than a year.

I started back on thyroxine on February after a health test at work revealed a resting heart rate of 95bpm. My GP suggested I start back on thyroxine and i've slowly climbed up to 75mcg.

Although brain fog is lifting a little, I keep gaining weight, which I can't control. It's all in my stomach and it's pretty unsightly and extremely uncomfortable. It can also be pretty sore and pressurised/gassy most afternoons, which isn't ideal when it's noisy in meetings. No matter what I do I can't shift the weight. Lack of appetite, hair loss and extremely itchy inner ears continue to be a problem.

Although I know if I came off/reduced meds, I'd probably drop a few pounds. I usually feel better after a few days of coming off them but I'm trying hard not to mess about with my meds.

Does anyone else have this problem? I should say I'm on Vitamin D and B12, too.

Most recent blood tests when on 75mcg:

TSH 2.34 (0.55-4.78)

FT4 18 (10-25)

FT3 4.7 (4.0-7.0)

Tests from 3 months ago when on 25mcg:

TSH 4.41 (0.55-4.78)

Ft4 14 (10-25)

As always, thanks for listening,

Tired x

cant tell you anything im afraid. but im increasingly concerned by the number of people coming on here saying their dr decided they didnt need meds (wtf!!!)

Tiredofthis77 in reply toWetsuiter

Yup. I even went to a private specialist and he told me I was just unfortunate and depressed lol. That advice was costly money-wise and health-wise which left me untreated for a year and a half

You are still undermedicated. Your symptoms are more likely to be due to low thyroid hormones rather than levo. When on levo your tsh should be 1 or lower. This is where we generally feel at our best. You Ft3 is low and an increase in levo should raise this. It is low ft3 that causes the symptoms.

Thank you. I have been tempted to stop but I'll soldier on. Thank you

There are a few of us on here who have done that.... And made themselves quite ill. It is a strange thing that we can't explain but when you stop levo you feel quite good......... For a while. Then hypo hits. I was undermedicated for years and put my symptoms down to levo so I reduced and reduced. By the time the symptoms really hit tsh was 32,ft4 10 and Ft3 3.

Being inadequately treated is responsible for weight gain

Your results show you are under medicated and poor converter

Getting all four vitamins OPTIMAL helps conversion

Selenium supplements can help improve conversion of FT4 to FT3

Vitamin levels need retesting regularly. Folate, ferritin, B12 and vitamin D

You need 25mcg dose increase in Levothyroxine and bloods retested 6-8 weeks later

FT4 only 53% through range

FT3 only 23% through range

Presumably you have Hashimoto's diagnosed by high thyroid antibodies?

If you have ever had high thyroid antibodies at any test this confirms Hashimoto's

Strictly gluten free diet helps thousands of patients with Hashimoto's to improve poor gut issues

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

While still eating high gluten diet ask GP for coeliac blood test first or buy test online for under £20, just to rule it out first

Assuming test is negative you can immediately go on strictly gluten free diet

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially)

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

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

Thank you. I’m just puzzled as to why I’ve lost weight when I’ve stopped meds in the past. I’m particularly puzzled as to why I’ve gained a stone since going back on meds in February and just wondered if anyone else had the same issue. It’s so soul destroying

SlowDragonAdministrator in reply toTiredofthis77

Many hypothyroid patients struggle to maintain weight when not treated or very under treated (like coeliac patients)

Gut function can be badly affected by being hypothyroid

Vitamin levels drop as direct result

As a person who drastically gains weight, suffers terrible bloating, and generally feels terrible the higher my levo dose goes, I would suggest reading posts on here about T3/T4-combined and T3-only treatment. For me, slowwwwly reducing my levo back and sloooowly increasing my T3, plus all the advice about vitamins, as directed here, has helped a great deal. I am convinced that while some people - millions - do fine on levo only, for some of us levo is somehow just not a good medicine, and taking more makes it worse, not better. Just my opinion, for my own self!

jgelliss in reply toThyroQueen

Many do Great with T4 only because they are good converters. But some of us that are not good converters need to add some T3/NDT to our T4 dose . Journaling ones symptoms and getting copies of the lab results with the dose written on the lab results are very helpful to find our *Optimal*.

It's very possible that your adrenals picked up the slack . That can cause adrenal fatigue . Thyroid and adrenals work in unison. Being optimally dosed with thyroid meds will help you with over all well being.

Cup-cake7 profile image
Cup-cake7 in reply tojgelliss

I agree to check adrenals, as I couldn't even get to levo 50 until I'd worked on adrenals, now I'm stuck on 75 Tsh 4.5

But I feel as though I still have a piece of jigsaw missing. I've worked on gut. I am gf Yes important and the vits helped a lot. But am very stressed unfortunately

I rang for an iodine test at Medichecks but they have stopped it now, I'm grasping at straws but 🤷‍♀️ I'd like to know

May I ask what was your t3 when you were on 25mg?

Just wondered ? My weight is stuck too

I lost some for a wedding but mum adrenaline was pumping sorting things out and I put it back in a flash afterwards

To loose weight initially did slimming world and lost half a pound so adapted good fat diet, coconut oil, advocados, few nuts, ate clean ,eats, chicken and veg, only treat was ocassional popcorn, I was a very good girl lol which took me down a stone and half in nine months

I'm so sorry your not feeling yourself well yet . I had TT many years ago . Prior to my TT I was dosed with 112mcg T4 . At that time I still had some thyroid function so my dose was lower. After my TT I was dosed with 150mcg went up to 175mcg . My Dr wanted me to be suppressed . I was having all kinds of symptoms including palpitations , insomnia, fatigue, high blood pressure , head aches/pressure , digestive issue , anxiety, sweating, etc.

Years later I switch to a new Endo who lowered my T4 dose and added NDT for my T3 mix. It's made a huge improvements for me . I am not a good T4 converter to T3 . Being on nutrients vitamin "D"/K2 , B-Complex, B12/folate, magnesium, minerals, Iron if you test low, Celtic Sea Salt for adrenals/electrolytes.

Keep an eye out for your liver/gallbladder issues . Support it if you feel any problems rising .First and most importantly test your liver enzymes when you run thyroid markers.

Liver function tests are blood tests that check to see how well your liver is working. ... Enzymes that are found in the liver, including alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (GGT) Bilirubin, a yellow substance that is part of bile.

Cup-cake7 in reply tojgelliss

Please after reading,

How do you support liver?

Where do you get your sea salt?, Dr Myhill does them I was just considering

Il look up electrolytes

So glad you found your way

jgelliss profile image
jgelliss in reply toCup-cake7

First I would find out if you need to support your liver . I was on T4 only for many years and developed jaundice and fatty liver . I started to have pain on my upper right side abdomen . I omitted gluten sugar dairy coffee chocolate soy . In addition I take digestive enzymes Betaine HCl . Milk Thistle for my liver. In particular I use Liver Health by Herb Pharms. I exercise eat very small amounts of red beets carrots greens . Adding some small dose NDT for my T3 mix with my T4 made a huge difference for me too .

I use Celtic Sea Salt .

Best Wishes.

Re weight loss

The Only time I lost weight easily I now analyse as a hypo swing mixed with menopausal sex hormone stuff

My mood was all over the place

An interesting read is if you go on

Professor Studd Wimpole St

He shows how women's reproduction depressions, menopause etc influence and there is a patterning - yes, quite relieved to be reassured I hadn't caught a disease called bipolar. Lololol.

Could you be having hypo swing, havenyou Hashi.

Yes we re a complicated mix 🙃😘

Plenty coeliac blood test kits online

Even on amazon

Just google

Coeliac blood test

Quest2019 in reply toSlowDragon

Ok. Will go to GP if I get no help than I will look. Are they reliable . Sorry so Many queries!

SlowDragon profile image
SlowDragonAdministrator in reply toQuest2019

Yes .....well as reliable as any coeliac blood test.....i.e. Not very reliable. They only pick up coeliac not gluten intolerance

healthcheckshop.co.uk/store...

coeliac.org.uk/information-...

But if you test positive for coeliac Medics take far more notice (even nowadays) of positive coeliac results over "only" gluten intolerance .....even though they cause similar symptoms and problems

Assuming test is negative you can immediately go on strictly gluten free diet

(If test is positive you will need to see GP and remain on high gluten diet until endoscopy, maximum 6 weeks wait officially. In practice can be very much longer)

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Hi SlowDragon, thank you again. Where in the range for FT4/FT3 should I be aiming for? My FT4 increased a good bit after increasing to 75mcg. I so wish I had the FT3 test when I was on the lower dose - I dread to think what the results would have been. You mentioned it looked like I was a poor converter. And in hindsight, I wonder if this is what my problem has always been, which is so frustrating as I've wasted so many years feeling terrible and yo-yo-ing on thyroxine. Do you think I should mention T3 to doc or go down the vitamin route first?

SlowDragon profile image
SlowDragonAdministrator in reply toTiredofthis77

FT4 only 53% through range

FT3 only 23% through range

Useful calculator for working out % through range

chorobytarczycy.eu/kalkulator

Getting vitamins optimal can help improve conversion

The aim of Levothyroxine is to increase the dose slowly in 25mcg steps upwards until TSH is under 2 (many need TSH significantly under one) and

most important is that FT4 in top third of range and FT3 at least half way in range

NHS guidelines on Levothyroxine including that

most patients eventually need somewhere between 100mcg and 200mcg Levothyroxine.

nhs.uk/medicines/levothyrox...

Also what foods to avoid (eg recommended to avoid calcium rich foods at least four hours from taking Levo)

All four vitamins need to be regularly tested and frequently need supplementing to maintain optimal levels

Getting dose increase in Levothyroxine and vitamin levels optimal are first steps

Absolutely, strictly gluten free diet helps thousands

.....what I'd done for years to loose weight didn't work any more, and was in effect wrong and un healthy. It was very low fat , I've wondered how much this type of diet contributed, and of course it was brain washing about fats that lead the way, spreads not butter etc

SlowDragon profile image
SlowDragonAdministrator in reply toCup-cake7

Yes

I now have full fat milk, butter and full fat yogurt

Grass fed beef etc

Good fats, good protein and limited carbs

Cutting out virtually all beige carbs

Cup-cake7 profile image
Cup-cake7 in reply toSlowDragon

....fab. It makes us feel so much better does t it, and cravings go, far easier to stick to as you feel better

I instantly feel better after oats, I've read there is a calming thing 🤷‍♀️ With oats. Maybe placeoba lol

Whatever works for us, but I wonder if I'd not been constantly trying to loose weight, cut out good fats etc for years when young and vain, of I'd have not developed this way, who knows

Keep going. What I struggle with is being disciplined as I've been a free spirit most of my life

Why has most choc got soya in it then?

It's cheap way of getting it smooth

Expensive chocolate doesn't tend to use it

Cup-cake7 profile image
Cup-cake7 in reply toSlowDragon

Sorry I'm not understanding

What is a cheap way to get it smooth? Taking soya out?

(I thought we were meant to avoid soya?)

SlowDragon profile image
SlowDragonAdministrator in reply toCup-cake7

Yes we need to avoid all soya including soya lecithin

Soya lecithin is in most chocolate. It's a cheap emulsifier.

Most expensive chocolate doesn't use any soya

Cadbury's seem to recently realised that soya is an issue for many ......a lot of Cadbury chocolate now seems to be soya free

Others that seem to be soya free......(always read the Gp label)

Divine chocolate

Some dark Green and Black

Montezeumas

Waitrose new range

A resting heart rate of 95 is perhaps a little high So why did your GP reintroduce Levothyroxine, as we’d expect it to increase your resting heart rate further.
