Low muscle mass

Elisabetho profile image
30 Replies

Hi,

I have been on a set dose that is as optimal as can be expected - for approx 2 years.

Levaxin 150 mcg

Liotyronin 5 mcg (+an extra 5 mcg once in a while, when my pulse goes down to mid-50s).

My question is if anyone else has low muscle mass, and difficulty increasing muscle mass? Does anyone know anything about if the effect of natural thyroid hormone (that healthy thyroids produce) on the mitochondria is different from the effect of synthetic thyroid hormone?

Thanks 😊

See from your profile you are in Norway

Do you have actual results and ranges you can add

T3 dose really should be constant...not adding in extra now and then

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

If/when also on T3, make sure to take last dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test

Thank you for the reply SlowDragon, and all the good tips.

I don’t have any recent results, but my TSH is always less than 0.01, and T4 and T3 high end of range. Vitamins and minerals optimal. TPO between 300-400.

I take both T4 and T3 at 10 pm and normally blood tests the following morning, so this could have an effect. If I don’t take my meds before bed I can’t sleep, and blood tests must be done before 10:30 am.

I know that I should be taking a steady dose of T3, however if I take 10 mcg I am over medicated (heart pounding, sweating, high pulse), if I take a steady 5 mcg on average once a week I feel very low, my pulse drops (sometimes under 50) and I feel awful. Taking an extra 5 mcg of T3 helps almost within half an hour.

Are you saying that an optimal dose of T3 should help build muscle? Do you know of any scientific papers on the subject?

I have recently changes my doctor. Will have new tests done soon.

Thanks 🌺

Do you ever try a split dose T3

5mcg at bedtime and 5mcg 12 hours later

Elisabetho in reply to SlowDragon

Yes, I have tried that. It works the first couple of days, but then too much seems to build up in my system.

No, T3 does not build muscle, it increases the rate at which all tissue is "burned up" (ie it is catabolic) and if you do not do anything to replace it, you will have muscle and fat loss. In case anyone is wondering why bodybuilders take T3, it is NOT to build muscle as it does not do that, it is to reduce body fat %ages to single figures before a show, and, as it can cause muscle loss, it is usually stacked with an anabolic steroid, lots of protein and heavy training to counteract that (but bodybuilders aren't hypo to start with). Having said that, I haven't noticed any more muscle loss than I'd expect from aging. I really should take up some resistance training again, but - life ...

My son is into body building and drinks this high protein drink that he buys online to build up his muscles.

Thanks for the tip!

I will probably try to incorporate more protein in the form of chicken and fish.

I guess my body was out to lunch...my t3 hadn't help my fat loss at all...lol

Since my thyroid has started working I have lost about 1 1/2 stones without dieting. It just shows how our metabolism affects the whole body because my hair is now growing back and not dropping out like it was. I just hope this lasts longer than 4 years this time because it is all so unpredictable.

Your lucky me not so much.

Lora7again in reply to Batty1

I don't feel that lucky to be honest because I am frightened I will have another thyroid storm. I did think I was going to have one on Monday when I was sent to A & E because of this nasty flu bug but I seem to be better now and I am not coughing as much as I was.

I mean lucky that you have a thyroid ...Im thyroidless.

Lora7again in reply to Batty1

I don't know what the future holds I might end up the same as you but hopefully one day the NHS will start to treat thyroid patients better than they have been doing so far. I actually think the treatment has gone backwards because of the TSH. Years ago Doctors treated patients by symptoms not blood tests and that worked well for them.

Very interesting - when you say working again, is that due to meds?

Lora7again profile image
Lora7again in reply to Elisabetho

No meds at the moment but I did take Thyroid S a couple of years ago. The only thing I am taking is vitamin D spray and selenium tablets. I am waiting for a blood test so I will post it on here to see what other members think.

Well, you're just trying normalise your T3 to what an ordinary healthy person would have, but a bodybuilder is training hard 6 days a week and eating very few calories (for a short time) as well as taking T3.

Batty1 profile image
Batty1 in reply to Angel_of_the_North

What exactly is a normal persons T3 level? I'm not sure the lab ranges we are forced to live within are not created with all healthy individuals.

Lora7again profile image
Lora7again in reply to Batty1

I think it is somewhere between 4 and 5 because their thyroid is healthy. I saw my son in-laws results and his TSH was 1.05.

See the study by Pilo or the critique by Tania Smith. It's very variable and individual, as is level of T4, but it follows a daily cycle

I hope you get an answer to the muscle mass question.

My muscles wasted because I was lying in bed for over 2 years because I was hypo. I have been in remission now for over 6 months and I can see that they are starting to build up again because I am more active. This probably won't help but are you quite active? I do know as we age we lose muscle mass because I have now I am 60 and I think a lot of older people do pilates or some kind of light exercise. My daughter tells me I should do yoga and I might do once the weather improves.

Thanks for sharing Lora7again. I also was inactive for several years until I got my dose right, but I have been relatively active for a few years. Walking the dog every day, doing a lot around the house, playing with my grandson (I live with my daughter and family). But my muscle mass is the same and I can not do strenuous work or exercise. Tried beginners yoga, but it was too hard and I had to settle for yin yoga.

Going up 2 flights of stairs makes me pant.

I am 56 😀

I get palpitations if I over do it so I can't really run after my little grandson which is frustrating because I used to be quite fit. I played badminton and tennis and was also a horse rider but I cannot do any of that now.

Elisabetho in reply to Lora7again

I used to go for long walks, and mountains were never a problem.

The article you posted was very interesting. I probably don’t get enough dietary protein and vitamin D, though I do take vit D supplement. Maybe most importantly I don’t have enough testosterone. I used to take some DHEA. Maybe I will try these again.

Thanks 🙏

You can test cortisol and DHEa via Regenerus saliva testing

Recommend testing vitamin D, folate, B12 and ferritin at least annually ...ideally twice yearly

The condition of losing muscle mass as we age is called sarcopenia. I'm not sure if losing muscle mass can be avoided completely, but I suspect it could be delayed with the right diet and exercise.

There are ways of slowing down the development of sarcopenia by avoiding things like malnutrition, eating a nutrient-dense diet, eating enough, doing regular weight bearing exercise, avoiding immobility, eating enough protein...

It would be worth your while to look up sarcopenia.

Based on many posts I've read on this forum I think not eating enough in women with hypothyroidism would be a common problem. Malnutrition would follow. It is possible to be obese and yet be malnourished.

Oh, I understand you. All my life I had very skin body. When i have started to go to the gym, of course I wanted to increase the level of muscles in my body. Exercises helped, but it was very slowly. I tried to ask all my friends who like sport, what I should do to expedite the process. All of them recommended use SARM's.I didn't know anything about it and even didn't know where to buy it. Thanks that I have found thblack.com/where-to-buy-sa... , there is a big article on this thread. Hope that I have helped you
