Can hpylori make your metabolism faster? since i've had it (9months now) my weight won't go back to what it used to be i'm too skinny now bmi 17

No: It won't make your metabolism faster, but it certainly could alter your food intake. If you've had hpylori for 9 mos, why haven't you had it treated and cured?

Not unless...: Not unless you are suffering from a yet to be diagnosed h. Pylori peptic ulcer. More common things cause weight loss which must be discussed with one's family doctor or internist. Psychiatric factors are also considered.
