I’m a 21 years old female, 3 years post gastric sleeve. I’ve been dealing with neurological problems for over a year and last may my doctor asked me to take a vit B complex because I’m malnutritioned, I took it for a week and I ended up with a x200% or the normal value of B6 levels, my drs asked me to ignore it and stop taking the complex because I reached B6 toxicity. 5 months later its still double the normal level. I have kyphosis, bilateral thyroid nodules and tremors. i’m also anemic with a ferritin level of 4. And I went into tetany 4-5 times this year after hyperventilating.
