i dont think i quite understand this, so if someone could give me a idea of what causes the bleeding in crohns?
(this may sound dumb ...)
i know the ulcers. do they bleed because they are ulcers or , like randy said, eat into vessels or veins? when there is bleeding, are they getting bigger?
in my H's endoscope, his ulcers were white, cone shaped things. not the craters i was thinking. his colon had the red craters, tho.
something bleeds, perhaps when it gets so irritated or inflamed?
trying to understand where the blood comes from or why...
tyia* for any answers. :)

The way I understand it, the ulcers themselves can bleed. When the inflammation gets irritated you can experience bleeding. Sever bleeding can be caused when an ulcer gets very deep at hits vessels. That happened to me.

They described some of his ulcers as coned shape? I wonder if that was scar tissue. They didn't say they were polyps by chance? I always picture "crater" too when I think of the ulcers.

Diagnosed with mild Crohn's Disease 2/06 after sever GI bleed. Has been suffering since 1998. History of rectal fistula and gallbladder removal. Currently taking Asacol and Questran.

hey jodyisme, a cone shaped ulcer would be like a zit. inflamed around the edge and have a whitish tip. or all red as i have seen is some of my pictures from scopes. like any wound they can bleed. depending on the size they can eat through the inner lining of the intestine causing a bleed. the intestine has very many blood supply vessels. the main function of which is to transport nutrients throughout the body and take waste to the kidneys and liver to be filtered and removed. once an ulcer gets through the lining , just figure that the digestive enzymes in the intestines no longer are held back by the mucous lining and are free to "digest" the outer layers of intestine. the result may be a bleed, or the beginnings of a fistula. once the hole is made, your body will try to wall off the area and may form an abcess, a fistula, or both. believe it or not these are protecting you from further infection. an abcess will contain the infection giving you time to seek medical help. a fistula will form to let the abcess or perferation drain away the fluid also alerting you to seek help. i hope this explanation helps with your understanding of the process.

BTW i see you are fairly new here, have you visited my crohns website? its somewhat informative.

thanks randy, i will go look at it. :) its my husband who has crohns, just so everyone knows. i like your explanation...thanks:)
jen, hi. the cone shaped are in his stomach, or were when his endo was done. his esophagus was also narrowed, and it was stretched.  i cant read the pics real well, i only know the dr called em "ulcers". the colonoscopy now, it was full of red dots, spots, white spots, and areas plain red as fire. (we got pics of the tests) blank areas, then areas all dotted. (healthy colon is pink, i learned) quite interesting, actually. his small intestine, at the time and maybe still, was not affected. colon and stomach were. im always afraid his stomach ones will bleed, this blood is from the colon tho...its too red to be farther up.
i will have a weird scrapbook--lol--from my granddaughters colon and my H's...LOL. not everyone has colon pics! we are all special!
well, i can see, considering the blood and amount my H has, its obvious they are working themselves very inflamed and such, perhaps bigger?  
no, not polyps. as randy said, they actually look like a weird zit. ICK. (hadnt thought of it that way before) but they were ALL over his stomach, i mean looked like a field of them blooming or something.
thanks, yall, appreciate the help! he has done this before, but it still scares me. i always wonder is this the time it hits something big?
unless he is in pain , he has no intent of having it checked  out any more.
talk about needing a mule to kick ya!
