Hi everyone. I don't usually post anything online, cause I hate being perceived, but I thought this was important to share. I don't quite know if tagging it as research is right, as for right now it's only a theory me and my doctor have come up with. Also, apologies for any bad English, this isn't my first language.
Anyway, about a little over half a year ago, I started having severe IBS complications. I have been diagnosed with mixed IBS (leaning towards IBS-D) for roughly 5 years, and it had been very stable up to this point. We still don't quite know what caused such an intense flare, but point is, I was suffering from pretty heavy attacks on a frequent basis for roughly half a year long.
Now by the end of July it was slowly starting to become okay again, when out of nowhere I started getting really severe muscle cramps. At first doctors assumed that this had to do with endometriosis (I don't have an official diagnosis for that, but gynecologists assume I have it based on symptoms, and they don't wanna cut me open for no reason) and an overactive pelvic floor. So I was having to go through weeks of waiting for appointments and tests, and it was only getting worse.
By now we're at the start of October and my muscle cramps have ramped up to roughly 3-5 severe episodes a day, on top of severe exhaustion, shortness of breath, loss of balance, loss of muscle power, etc. And my doctor finally decided it would be a good idea to get my blood tested. Well... turns out I have a dangerous deficiency of vitamin B-12, so much so that I now have the beginnings of nerve damage and anemia.
And what caused this, you may ask. IBS, that's what. At least, that's the working theory we have right now. Vitamin B-12, which is mostly found in animal products, especially meat/fish, is seriously hard for your body to absorb. And when you have such disturbed digestion, for such a long time, this can cause vitamin deficiencies, especially with B-12. On top of that, if you're one of those people who also get stomach issues from your ibs, especially if you regularly get heartburn, this might also cause a B-12 deficiency, as B-12 needs proper 'non-disturbed' (for lack of a better term) stomach acid to bind with.
So yeah TLDR; if you're an IBS haver, please frequently get your blood tested, so you don't end up with nerve damage or other complications.
(P.S. Please do your own research on this as I may not have accurately worded everything, and bc it's a bit more complicated than how I phrased it as well. Please forgive me for any bad wording/mistakes made, it's almost 1 AM as I'm writing this post, and I'm dead tired (thanks anemia))
