Thyroid

Can anyone tell me how soy contributes to your thyroid problem.  I take soy in a lot of vitamins and other products.  I just wondered how does it affect your thyroid or is it the meds it interfers with.  I always take anything with soy 5 to 10 h rs after taking meds.  I just wondered if there was another reason for not taking anything with soy if you were hypothryoid.

Soy is a goitrogen, and interferes with thyroid function.  I've read that soy can also inhibit absorption of thyroid medication, but I'd have to find that again, in order to verify it.

It would be better to avoid it altogether, if possible.  I always look for products that do not have soy in them.

Nearly all the supplements I take contain some soy.  I called one of the companies and they said it was just in the coating and did not contain enough to contribute to thyroid function.  Most of commercially pkg foods say soy.  And what do you eat if you delete all the foods that are goitrogen?  It was suggested by my dr. I needed to eat some of these because I am constipated all the time.  When you have other symptoms besides Hashimoto's it sure does make it hard to choose what to eat or take.  I also have high cholo. so I am trying to eat products to control that and then some of them go against over things I have wrong with me.  It's almost like a no win situation.  Just don't eat or take anything.....

Sounds like you still have some hypo symptoms.  If you would please post your thyroid test results and their reference ranges, members can better assess the adequacy of your testing and treatment.  Also, what thyroid med and dosage?

There is a large variety of supplements on the market that do not contain soy.  Soy can also interfere with absorption of thyroid medication.

You don't have to eliminate all the goitrogens.  Things like broccoli, cauliflower, and other veggies, lose their goitrogenic properties when cooked.  Steaming is best to preserve the nutrients.  Yes, the fiber in these veggies is very good for helping with the constipation of being hypo.

Constipation is a major hypo symptom, so I agree with gimel.

No one has ever checked Free T3 or T4.  All they ever check is total TSH and the last time checked it was 1.45.  I take .75 mcg of Synthyroid.  Trying to find a dr. who will do a complete check.  I do have the Hashimoto's or at least that is what the endo said.

TSH is a pituitary hormone that is affected by so many variables that it is totally inadequate as the sole diagnostic for thyroid status.  At best it is an indicator, to be considered along with more important indicators such as symptoms and also levels of the biologically active thyroid hormones, Free t3 and Free T4 (not the same as Total T3 and T4).  Free T3 is the most important because it largely regulates metabolism and many other body functions.  Scientific studies have also shown that Free T3 correlated best with hypo symptoms, while Free T4 and TSH did not correlate at all.  

A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve hypo symptoms without being constrained by resultant TSH levels.  Symptom relief should be all important, not just test results.  Since you have Hashi's, it is even more important to find a good thyroid doctor because the gradual destruction of your thyroid gland will cause you to need continual increases in thyroid meds.  This cannot be managed by relying only on TSH.  You need to be treated clinically, with a close eye on your Free T3 and Free T4 levels.

Thanks for the advice.  I am going to make an appointment with an endo that someone recommended that does check all of that.  Going to take my list with me and if he doesn't I will move on to greener pastures hopefully.  Tried one endo who said you don't need anything checked but total TSH.  Marked him off of list and did not go back. My regular dr. recommended I go to one because he said he did not know how to do the free T3 or T4 that he was only trained in medical school about total TSH.

Where are you located?  I ask because I do have one doctor recommendation for the Auburn area.
