Wow, I'm so glad to hear that the L1 may have helped that in some way.
I agree that the iron is certainly the culprit, but I'm also wondering if anyone else has this "redundant colon" that they found that I have. I also agree that these doctors give the label of "IBS" and other generic names when they don't know what the problem is. I hate when they do that. I don't know for sure if I have IBS, but I know that I have the abnormally long colon, which makes it harder for stool to pass through, because by the time it gets to the end, all the water is removed from it. The large intestine removes excess water from it's contents, so if the colon is too long, it will definitely make things harder to pass when the contents have no water in them, so they end up getting stuck in there.
I think this just may be something that runs in my family, but I'm also wondering if the ones that have it, are the ones that have Thal minor also. I think this Thalassemia trait does more than doctors know about, because even people with Thal minor/trait sometimes have symptoms that range from minor to severe.
If you can find out the name of that medicine you mentioned, I'd appreciate it. Thanks, Poirot.
Oh, and you didn't vote!
