These may be some dumb questions, but I don't know what these things are and/or the differences between them.  From recent posts, I can see that they are both painful and dangerous, but that is almost all I know about them.
Stricture, I *think* this would be like scar-tissue around a portion of bowel, making the diameter for waste to pass through smaller than usual.  Can strictures be flexible, or are they a solid/set opening, similar to a pulled thread in fabric making an opening in a garment of clothing smaller?  ...and if you force a limb through a garment with a pulled thread, it will tear/rip the thread.  Same thing happen inside us, too?  *bites fingernails*
The various Obstructions...I haven't got a clue.  Are they caused by the bowel closing down?, scar tissue?, diseased tissue?, waste being stuck?, and what *is* a mechanical obstruction and how does it differ from other obstructions?
Thanks for any/all help in understanding terminology.  blush

I have the ability of single-minded determination and accurate project focu....Hey, look, a cat!
Crohn's and UC are pretty darn crappy, but if you can't laugh at yourself, you'll cry......I'd much rather laugh.
2001 Dx'd with UC.  (asacol, hi-doses pred, colazol, 6MP=jaundice, remicade)  No remission. 
5/2008 surgery, removal of 6" of left side colon.  Dx changed to Crohn's. 
Changed maintenance med to Methotrexate (MTX) and am remaining manageable with 2tabs Immodium and a probiotic capsule every 12hrs.

yes you have it correct ,,,
eg. internal hemmorhoid as an obstruction or waste backup due to stricture as obstruction.
Mechanical category:
1. Intraluminal (eg, foreign bodies, bezoars, food bolus)
2. Obstruction resulting from lesions in the bowel wall (eg, tumors, Crohn disease)
3. Extrinsic (eg, adhesions, hernias, volvulus)

easy google for that

Another category should be surface tension (or something like it)... we need to evacuate gas and with an inflammed bowel this is difficult especially with water stool that doesnt let the gas pass easily, leading to more inflammation. This is complicated by lipid digestion problems. Supposedly a medicine such as asacol provides some lubricating effect.
