Hi - I'm afraid your blood test results dont mean much without the ranges -thats the figures in brackets after your results. Every lab seems to have its own ranges. My story is so similar to yours and weight loss was one of my main drivers. I too worked out until I became so exhausted I could only sit and yawn. Now on T4/T3 and beginning to feel a little better. As for the weight......I'm still finding that dropping the carbs is the most effective way. Hoping that the T3 can help prevent the return of weight lost.

I agree with Jezebel. Try the high fat low carb diet. Google it and make sure you follow it to a t. It's enjoyable and its a lifestyle rather than a diet. Hypos don't process carbs efficiently so it gets stored as fat. Cut your carbs and you'll soon lose it and yes you can still workout without carbs!

Don't know if this helps, but when I was on higher T3 and lowered T4 my appetite was entirely out of control. Even though only T4 didn't feel good, at least I wasn't turning into a dirigible. Much tweaking and I'm taking a small amount of T3 along with the T4 dose that gave me a good fT4 and appetite is no longer overly enthusiastic. Slowly losing weight but not gone on major reducing diet. Just eating like a normal human.

I know other people lose weight when they get T3 added. We are all different.

Graciewoo, you don't appear to be undermedicated. FT3 is certainly high in range and may even be slightly over range which you might want to check.

I couldn't lose weight until I dropped the T4 entirely. Don't ask me why! But I Don't diet, and I certainly Don't go to the gym! Exercising uses up your T3, and you're only taking a very small dose. Your FT3 looks high, but what are the ranges?

It could be that you have nutritional deficiencies, they can make you put on weight, magnesium for example. Have you have any tested? B12, vit D, iron, etc? If not, best to do so.

Hugs, Grey

Your bloods seem optimal. It might be elsewhere. How are your lipids, liver values and digestion? I have lost alot of weight since starting combo T3 and latterly NDT. My liver values and cholesterol were not in a good place so I dropped as many carbs as I could (anything sugary, bread, pasta/potatoes/rice) and increased protein & veg. I also supplemented with milk thistle for the liver and digestive enyzmes so everything gets digested. Maybe its a broader range of things to target, not just ft3 alone.

Thanks for all your replies. I have tried low carbs, didnt work. I am now trying gluten free. Im amazed that I started to put weight on from going to the gym while on t3combo. Last year is when I lost weight at the gym while only on thyroxine. It is so frustrating to work this hard and sew inch gain

I used the 5:2 to shed 24lbs but take only a high dose of T3.

Interestingly, when I had a duff batch of T3 I could not lose any weight but as soon as I took a different batch the weight came off again. I now do the odd 500 calorie day just to stay slimmer.

in reply topenny

My endo will not hear of me stopping t4and just taking t3, have you had a total thyroidectomy ?

penny in reply to

No. I went to see Dr. P. who advised that I cut back on the NDT and introduce a little T3. I only felt well when I had stopped all T4 and was on T3 only. It took quite a long time as there was a break of about 2 weeks between adjustments. (I actually stopped all medication for 2 weeks to take adrenal support - I was a bit ill for that time and put on more weight.) I kept the adrenal support for a couple of years.

Anyway, my GP suddenly decided that I was not hypo. and stopped my T3 so now I self-medicate. I would say that I became intolerant of T4 and was not converting to T3 so would build up T4 and become toxic.

I've not had any luck with an endo., they quote my blood tests which did not diagnose me first nor last. Do you have complete faith in your endo.? He/she may be an absolute gem but in my experience the medical profession are woefully ignorant of thyroid issues and I probably know more than the average GP and I've got a brain like a sieve! If you're not well at the moment maybe you need to quiz your endo.

in reply topenny

Well I insisted being referred back to an endo as I felt so ill andmy gp would not let me add t3. Apart from feeling awful my main problem is the weight gain for me. I saw my endo once, he added t3 and discharged me. He shrugged his shoulders as to why I cant lose weight. He was happy to take my thyroid away but has no answers now the job is done. How will the problem ever be sorted if the so called expert jas no idea what to do.....

I didn't loose weight until the t4 was gone, like Grey goose. It looks like you are not converting your t4 to t3, but we need ranges with your labs, please.

in reply tofaith63

When I was on t4 alone I lost 5lbs, which is nothing I know, but now on combination not only can I not lose an ounce but im gaining weight. Do you think the combination id not suitable for me maybe ?
