New to the forum and apologies if this is the wrong forum to be posting in!
Just a quick history:
When I was 11, 2005, I had an episode of violent vomiting for less than 24 hours and felt great the next day. Within a week I was experiencing constant nauseous waves lasting a couple of minutes-hours followed by intense heartburn, particularly at night. My doctor thought I was having what she called stomach migraines and I was prescribed ranitidine which did help and I was taking them for around 3 years. I was symptom free until I turned 16 when the stress of starting college seemed to kick off IBS, after a year of useless antispasmodics I was told to take Imodium whenever needed, ended up taking roughly 2 a day for a year. Decided enough was enough and when I turned 19 decided to go Paleo which largely brought my symptoms under control. However, over the years, I had begun to experience more and more brain fog, depression, irritability etc. Mostly this was okay and was manageable but not preferable.
Fast forward to 6 weeks ago I decided to try taking zinc for some eczema on my hands, which actually worked great and cleared up completely. 2 weeks ago I figured it was possible that I wasn't absorbing B12 properly so I took 1000mcg cyanocobalamin 3 days in a row then swapped to methylcobalamin same dose, actually felt pretty good for the first few days but on the fourth day I experienced extreme nausea and had to go home from work. I stopped the zinc and B12 immediately but the last two weeks have been hell. My brain fog, confusion and depression have spiked dramatically. It's hard to explain but I feel like a different person, I'm easily startled by sudden noises, find it harder to focus on things and my brain seems overwhelmed by too much visual stimuli. On top of that I find it harder to look people in the eyes when I'm talking to them. This is scaring me a lot and isn't my usual behavior. I have also been experiencing nausea after almost every meal and my body feels a little bit fluey.
So, I think when I was 11 I got H. Pylori. This settled down after a couple of years. I'm wondering if I may have had chronic mild asymptomatic gastritis causing B12 malabsorption. Is it possible that taking zinc, which supposedly kills h. pylori and then flooding my system with B12 has caused a flair up of gastritis causing the nausea after eating? I don't have pain but do have frequent heartburn. As for the neurological symptoms can B12 cause that? Can it get significantly worse before it gets better?
I'm having blood tests tomorrow and have been referred to the gastro so I'll update on results soon.
Sorry for the long, rambling post! If anyone has any advice or wisdom it would be hugely appreciated.
