my bm have changed, i went every day but 7 months ago that changed now i go 3,4,5, days without a bm. i throw up about once every 3 weeks, sometimes feel sick in my stomach, black stool one out of every 4 time i go, some times only do small amounts, or feel i can do more but can not get it out, last monday i threw up blood chunks or clots. i do smoke, and have a family history of cancer. i also have some light headiness. what else can it be? thanks send comments to [email protected]
