I've been treated for hypothyroidism for a quarter of a century - mostly using a mix of Armour and Eltroxin - and have never felt really 'right'. Many here will know exactly what I mean. A few months ago I decided to come off all artificial sweeteners - purely as an experiment to see if it was causing my IBS and food sensitivities. It was. My digestion slowed from 9 hours down to 30 hours - still short of the normal 40-ish but I suppose some things aren't completely reversible.
Then something really strange happened. I started to go from hypo to hyper.
It was difficult to tell at first as many symptoms are the same for both. But, with confirmatory blood tests I found I had to come off all medication as my thyroid had returned to normal levels. I still don't feel fantastic - but at least I no longer need meds. Researching the net it seems many rat and human studies now show nearly two-thirds of hypo patients who eliminate artificial sweeteners from their diet return to normal within a few months.
Thyroid antibodies dropped and returned to normal, TSH fell, and most of the patients were able to stop taking thyroid hormone replacement medication. This has been covered at the International Thyroid Congress since 2015. Has anyone else tries eliminating aspartame and other artificial sweeteners? It seems to have worked for me.
bynote: I've since found my testosterone levels are very low so I'm going to try medication to see if that helps with my fatigue and weakness - which I always used to associate with my thyroid.
