hypo, not eating, just started Tyroxine and I cant lose the few kg i gained.

Suffering from an eating disorder I know I am not intaking many kal. However, prior to Thyroxine and being diagnosed with hypo I gained over one size. I am eating less than a bird, I am scared that if thyroxin won't fix the problem I will fall deep in my eating disorder. If i eat less than my banana or a small salad a day I wont function anymore. My doctor told me the size gained would disappear in a few months, once the med work as it should, and to keep on working with my therapist to make sure I eat.....should i believe him? I don't have any appetite, i am scared and confused.

The thyroid controls metabolism and hypothyroidism causes metabolism to slow way down.  The doctor is correct that the medication should help your metabolism return to normal, once the medication has a chance to start working.  

I'm very sorry you're going through the eating disorder, as well as hypothyroidism.  Yes, you should believe your doctor that you should continue to work with your therapist to make sure you eat enough food.  Not eating enough can make it harder to lose weight than eating a healthy, balanced diet.  Moderate exercise is also good for you.

It's very important to make sure you have the right dosage of Thyroxine so that your metabolism gets back to what's normal for you, so it would be helpful if you tell us what dosage of Thyroxine you're on.  If you can, also, post your actual thyroid hormone levels and their corresponding reference ranges, it will be easier for us to help you.  We can remove a lot of the confusion for you if we know what your levels and their ranges are.  Hopefully, once you understand what's happening to you, some of the fear you feel might go away as well.

hello and thanks! The doctor wanted to start only from 50gm!
my lab 17.12.2018 Tyreotropiini, TSH 5.28
Is TSH the only test that was done?  Your doctor should have ordered the actual thyroid hormones.  Those are call Free T4 (Free Thyroxine) and Free T3 (Free Triiodothyronine).  TSH is pituitary hormone not a thyroid hormone and doesn't always correlate well with actual thyroid hormones.

Thyroxine is dosed in mcg vs gram.  50 mcg is a typical starting dosage for many of us.  When will you be retesting again?  Since it takes the medication 4-6 weeks to reach full potential, it's typical to retest approximately 6-8 weeks after starting medication.  You should ask your doctor to test for the actual thyroid hormones (Free T4 and Free T3) along with TSH, when you have your next tests since TSH is even more unreliable once we're taking replacement hormones.

You should also ask your doctor to test your thyroid antibodies to determine the cause of your hypothyroidism in case you have Hashimoto's, which is an autoimmune thyroid condition.  Hashimoto's is the most common cause of hypothyroidism and ultimately destroys the thyroid so it no longer produces any hormones on its own.  If you have Hashimoto's, you will eventually be completely dependent on your replacement thyroid medication.  As thyroid production decreases, it will be necessary to increase your dosage of medication.

The antibody tests you'll need to get done are Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TgAb).  

Your therapist should also be able to help explain some of this to you; however, if not, we'll be happy to explain how the thyroid works, testing that should be done to make sure you get the best treatment and what to expect as you proceed through this process.
I have no idea how to thank you for taking the time to answer in such a complete way and in details!
Last year Hashimoto was my diagnosis, they checked T4 and T3, for some reason in my latest tests i cannot find the values. I will get all the tests next week, but before I will definitely call the doctor and make sure, everything you suggested me is included. Thanks again for your kindness. I will update you!
As I noted, Hashimoto's is progressive and will eventually, completely destroy your thyroid.  You'll need increasing dosages of medication as your thyroid produces less of the hormones your body needs.

We'll look forward to seeing the results of all your tests and will be here to help you make sure you understand what you need in order to feel the best you can feel.

Hypo makes your metabolism crawl. I recently gained weight while eating relatively little too. Hypo sucks, but think about it this way, it's not your fault. You're doing nothing wrong. You have a medical condition that's causing this.  

As far as I know people usually lose all the weight they gained once their thyroid levels go back to normal. Thyroxine should help your body get the hormones it needs to control your metabolism and weight. It would be helpful if you could post your test results and tell us what dose your on.
