I find this interesting as I, along with many people, can suffer from IBS- even my osteopath when examining my stomach and back felt there was a problem with my stomach.I was diagnosed with an H Pylori infection back in May/June time when I started getting unexplained abdominal pain. At the time, the antibiotics were going to cost me £250 which I didn't have so I used indigestion remedies and altered my diet to include very alkaline foods to ease the acid my stomach was making, and after a month the pain subsided.Recently my stomach has started playing up again, and I knew it wasn't a passing bug after the nausea and vomiting wouldn't go away...so I decided to start the antibiotics to rid me of the infection [I know about 40% of the world has the H Pylori infection, but some people are more susceptible to the adverse effects of it than others]As part of the my taking the course of antibios I have read that this infection can cause a Vitamin 12 deficiency [hence some people with the infection develops pernicious anaemia] Although I do not have pernicious anaemia and when my twitching first started my blood work didn't show a vitamin 12 deficiency, I would be intrigued to see if my twitching improves by the end of the course of antibiotics and I get my probiotics back into me along with a vitamin 12 supplement.If anyone else suffers with regular indigestion, abdominal pain [not always but occassionally] or nausea [again not always but sometimes unexplained] weight loss or belching then it might be worth doing an H Pylori breath test.If my twitching improves after this course of antibios and going on an intensive replenishment of probios etc after I will let everyone know.Here is also a link to the connection between H pylori and vit 12 deficiency:
