Do you suspect you have an underactive thyroid (hypothyroidism) or Hashimoto’s? Or do you have one that you’ve been told is ‘optimally treated’, yet still have symptoms?

The following symptoms have been reported by patients on a large scale.

I myself have had most of these.

If you are on thyroid medication and still having these, you are likely not optimally treated, or have other things you need to address.

A properly treated thyroid condition should have no or very few symptoms. Of course, other illness, conditions and deficiencies can cause the below too. So explore them all where possible.

As well as optimising my thyroid medication, I also had to work on some other things to resolve all my symptoms.

(Not every thyroid patient will have all of these, but please let me know if I’ve missed any. Some of these reported patient symptoms listed below can be reflective of other conditions. An adequately treated underactive thyroid/hypothyroidism usually shows no or very little symptoms. These symptoms typically reflect an inadequately treated thyroid condition).

Many people find that they have their own combination of this long list of symptoms or even experience something not shown here. In fact, this list is by no means exhaustive; I’m always hearing about new symptoms. As thyroid hormone is required for every cell and every function in the body, when we don’t have enough of them, the effects are far reaching.

    Sue, what kind of vision problems do you have. I cant stand bright light, or reflective light. I cant go out on a sunny day because it makes my dizziness worse.

    I get something that I call brain zaps. They were really bad back in 2019 but are better now. They usually occur during the night and can range from barely noticeable to really intense and it changes from day to day. I did start to get these just after I quit citalopram but that was back in 2019 and I had been on citalopram before and not experienced them when I quit that first time. Not really sure if its actually inside my brain or if it’s just very fleeting muscle spasms, because sometimes i get a body jerk along with them, and at the same time I get a wooshing noise in my right ear, which is not tinnitus, because I also have that ( since I was 30 and I am now 60). When they were really bad my eyes would be involved and feel like they moved very tiny bit. Also the worse they are I would then have a really bad headache when I woke up in the morning. I also have problems with my vision. I cant stand bright reflective light and going outside on a sunny day is really bad. I have dizziness also and the light sensitivity makes it worse. My dizziness is hard to describe I sort of feel like I just got off a boat. the room is not spinning, but I feel like I am wobbling back and forth. I am much better now than I was back in 2019. I did just get diagnosed back in March of this year, so still getting used to medication. Also for several years until about 6 months ago, I think I had tensor tympani syndrome or something like it. I would have tapping in my right ear sort of like someone typing. It usually happened when I was lying down trying to fall asleep or if I was talking to someone on the phone. that has gone away.

    I tick around 97% off that little list you’ve come up with & have done since I was finally diagnosed back in circa 2003/04. All I have the energy for is, just to say, it’s just ridiculous beyond words & yet they call themselves educated!

    Where else in the world does it take just 1 singular blood test to find a serious health problem…?
    Where else in the world does it take just 1 singular medication to solve/manage that health problem…?
