Can't say I've come across any of the high street quacks referred to above yet, but then I'm only very early on in my journey, so who knows where it will lead me 🙂
I have come across a lot of stories of people that have been misdiagnosed due to some doctors following the letter of the law when it comes to blood test results, rather than taking those results alongside the symptoms, because they don't understand much about nutrition and how badly it can affect your body. Now to be fair, these stories are from a bunch of strangers on the Internet, who may well be making it all up 🙂
My own results show a very low B12, vitamin D and ferritin, and a high TSH result. But the doctors have only actually treated the vitamin D as that is below the range. Yet B12 and vitamin D deficiencies, low ferritin and hyperthyroidism can all cause my symptoms - mainly fatigue that's kept me off my full time job for the last 4 months, brain fog, joint/muscle pains, sleep problems and low mood swings, so to my mind it seems somewhat ridiculous not to even look at these as potential causes. I was very clearly dismissed by one doctor that I raised these specifics with, who basically told me to go home as there was nothing he could do! So I totally get the fobbed off feeling. I'm next booked in to see the GP that specialises in nutrition and CFS, so I'm hopeful that I can at least have an adult conversation instead of being treated like a naughty child, who doesn't know what she's talking about. Fine, I'm not a doctor but I'm a grown woman who knows her body and what is normal for me.
Just to be absolutely clear, I am NOT saying that you have been misdiagnosed. My point is that if you are unsure/unhappy with your diagnosis then to do your own research based on your actual results, not on an anecdotal 'your results are fine'. The unknown is always what's normal for you, rather what's in a normal range based on who knows how many thousands of people. From your own research you can then decide what action you want to take, whether that's going back to your GP for further information on your diagnosis, more tests, or a referral elsewhere.
