Genetics. I got fed a lot of throw away rubbish from the gastro doctor telling me it's because we are brought up in too clean an environment. Considering I'm 49 and grew up on farms, playing in dirt with animals, I knew this was a weak excuse. My Grandmother apparently had it and she was born round 1910ish. I think that something triggers it -I lived hard when younger, drank and smoked like no tomorrow- it probably starting kicking in over ten years before diagnosis- the pains and bleeding I thought were just from over exertion as a labourer and from hitting the booze too much. And, like a typical bloke ignoring signs not all is well in camp until the ---- hits the fan. I started getting weird illnesses, became sensitive to pesticides, and then allergic to bees which I went through 3 years desensitisation- soon as those jabs finished , hey presto my guts went nuts. Always had strange illnesses as a kiddie that nobody could work out.
I believe smoking has a lot to do with it. I know some research states it makes it worse but doesn't cause it. I've smoked since I was very young and quit about 8 months ago. As soon as I quit. I started my first bad flair and was hospitalized shortly after.
I love this thread, but there are now 15 pages of responses, and most are attributing the cause to their own personal circumstances. For instance, some cite female hormonal changes...but I have Crohns and I am a male. Some cite bee stings...never been allergic to anything in my life. Some say antibiotics, but I was healthy as a horse until Crohns hit at 30. The only common theme I really see is stress, but of course we have all experienced periods of extreme stress, and being highly individualized people that argument doesnt seem right to me either. Same with environmental issues... we are mostly all exposed to the same things and yet most don't get Crohns.
although some of the geographical studies are interesting, we know of no known pathogen that, like a carcinogen, if exposed to increases the chances of Crohns (although that accutane lawsuit was intriguing). This leads me to believe that Crohns is not environmental.
I believe that we Crohnies are statistical losers. If you look at enough numbers, anomalies appear, and we are those anamolies. Roll the dice ten times and nearly impossible to roll 6's every time. Roll them a billion times and unlikely you wont. It doesnt mean that something "caused" the instance where it occurred. We were not made perfectly, and try as we might to understand what causes our bodies to fail, there may be no explanation at all.

In 2011 a group of Danish investigators reported on their examination of pharmacy records for ... children born between 1995 and 2003...
Compared to healthy children, those that developed IBD were 84 percent more likely to have received antibiotics. Furthermore, children who had taken antibiotics had more than triple the risk of developing Crohns disease than those who were antibiotic-free.
Martin J. Blaser, MD, "Missing Microbes: How the overuse of antibiotics is fueling our modern plagues"
Based on that, I would wager that many of the anecdotes in this thread might need to examine early exposure to antibiotics as a factor. It seems likely that the disposition to the disease from early exposure to antibiotics might be stronger even than genetics. Oh, and what looks like a genetic disposition to the disease might really be that your acquired microbiota (mostly from your mom, but also other family members) might have been less than fully robust. Then some other later event (another hit from antibiotics, accutane, whatever), simply pushed you over the edge.
There is another possibility. Due to a genetic fault (NOD2 mutation) we have difficulty clearing certain bacteria and therefore have needed to resort to antibiotics more frequently. In that case, use of antibiotics is not the cause of the problem but the result of another underlying issue.
That quote came from the MAP vaccine site, which pretty much says MAP is necessary but not sufficient for CD (but not UC).Crohn's is not a genetic disease. Whether someone gets Crohn’s Disease (CD) is not determined by a single gene as it is for, say, Cystic Fibrosis, but genes do play an important role. A new technology called Genome Wide Scanning (GWS) has enabled scientists to scan the whole length of a person’s DNA looking for small changes. This has been done for many different diseases and also comparing different human populations. It has provided hugely important new insights into the potential causes and mechanisms of disease. When GWS has been done in thousands of people with CD and compared with thousands of people without CD (either in themselves or their families), some small changes or ‘mutations’ within genes have been consistently found in people with CD. Although many genes are involved, some mutations appear more frequently and are more important than others. The three most important genes associated with CD (called NOD2, ATG16L1 and IRGM) all affect the capacity of immune cells to get rid of bugs which live inside cells… like MAP! These exact same genes are also found to be highly associated with susceptibility to Tuberculosis and Leprosy (other members of the ‘Mycobacteria’ family). The truth that GWS and related methods have enabled us to see is that very many infectious diseases may be more likely to happen in some individuals rather than others because of inherited susceptibilities. So whilst you don’t inherit Crohn’s Disease, you can inherit a susceptibility to the bug that is causing it.

Moriati i'm really interested in that theory. I've never heard of birth control being linked to causing IBD.
Are there any study papers or reputable research you can point me in the direction of?
I'm not sure if it's a 100% thoroughly proven theory, but here's one paper I found: http://gut.bmj.com/content/46/1/140.1.full
We really can have no idea as to what caused our disease until they figure it out more.
I wonder if Rotovirus vaccine has an effect on the gut microbiome. I sort of doubt it, but wonder if it's been tested.My daughter was diagnosed at 3. In retrospect there were symptoms much earlier. The first foul BM with blood I noted within a few weeks after she received a Rotovirus vaccine. She was 2 months old and breastfed only.
So for her, it wasn't food, or environment, she's our 6th child of 7 and non of the others are sick.
I lean toward a combo of genetic predisposition, and perhaps a trigger from the Rotovirus vaccine.

Yours is a great case study. Your kids had no differences in antibiotics administered? No C-sections? All breast fed (that's super healthy for development of the microbiome). I would be interested in seeing PCR of all your kids' gut microbiome. Do you know about american gut project?
I do accept the current notion that the immune system is involved in the condition but I would contend that it is responding to a stimulous active in the body, hence the very high rate of spontaneous Crohn's remissions when the TB cure is administered. TB is not the only pathogen lurking in our bodies - the chicken pox virus that lives within many of us and manifests itself as shingles is an example of a known internalized stimulus, but could also prove to be the stimulus causing some folks Crohn's symptoms.
makes you wonder if some people with Crohns are actually misdiagnosed and have TB.
Keep in mind
Most individuals with crohns are tested for latent tb prior to starting any biologics
So this rules out tb for those folks
So please stop throwing unproven crap around that TB meds cure IBD or IBD is caused by TB. And in our wonderful inner city hopsital here we have a ton of TB patients- I do not recall one having CD. I just had my annual PPD for my hospital work, It was perfectly normal.
Enough of the TB talk. It's rubbish.
Before shooting from the hip you might do well to check the data.
Perhaps you've heard of Google well give it a try before unleashing your prejudices. You might also benefit from reading and understanding posts before commenting on them. Are you aware that Crohn's disease and IBD are not synonyms?
etc.
15 years of practicing medicine in one of largest US hospitals, 12 years of Crohn's disease myself, attending IBD conferences, contacts with some of the most respected researchers in the business whom I am in regular contact with. But yeah, I'm just "shooting from the hip."
But no, I guess you are right. You solved the nearly 100 year debate by reading google. Congrats on finding the cause and cure of IBD.
.
....hence the very high rate of spontaneous Crohn's remissions when the TB cure is administered.
Gee, you still didn't read and understand the posts or check the facts.
Instead, you chose to passive aggressively claim butter wouldn't melt in your mouth, then try to put me and my opinion down by telling me how great and more experienced you are than I could ever hope to be. Not nice and no way to refute a theory.
BTW, you don't need to use potty language to refute an theory and Crohn's disease and IBD are still not synonyms.
Don't take what I'm about to say personally, its based on my experience with classes of medical professionals not you in particular. I've been ill for a long time and in my Crohn's career I've encounter some really stellar individuals. Some who as it turned out actually saved my life and others who made it more liveable. And yet others, who, trading on the goodwill of the great, use that prestige to try to beat patients into submission to their prejudices, out dated methods and ideas.
I really do have hopes for you. I hope you take the time to read and understand my posts and if you still disagree take the time to marshal facts and ideas to produce a coherent theory of your own as to the causes and cures of Crohn's. I'd like to hear it.
FYI, I believe that the TB cure benefited me greatly even though it didn't cure my condition.
Maybe I didn't see it posted already, but where do you get this information?

And if you Google hard enough, you will find that there are many more studies showing the same thing.
You keep referring to "TB cure." Which medication or combination of medications are you specifically talking about? There is more than one.
"BTW, it was never my intention for folks to rush out and take the TB cure, just that it is something to consider as an option and should be discussed with your GI before proceeding."
This is a fair and reasonable statement...
In short, is it worth a question to a GI? sure, no harm in asking. But I would not run in the streets screaming we are on the cusp of curing CD based on a nice, but really not surprising incidental finding in a 7 year old study that hasn't been reproduced.
The question asked was "What's your theory on how you got Crohn's Disease?" not "Do you have a doctoral thesis on the genesis and cure of Crohn's disease".
And I stand by my theory!
At least as a working hypothesis.
Have you read any of the other posts?
I took issue with the statement "TB meds induce remission."
One reads this thread and is amazed. Many people are blaming it on perceived stress/a bug/the like, but we have not used a control. My guess is that if one picks 100 random healthy individuals, most will complain of stress/bug at some point in their life. In that sense, this group is not much different from controls. What is undeniable, though, is genetics. Since Crohn's is a rare condition, it is quite clear that genetics is the culprit. The most that can be said for stress is that it is a moderator.
