sibo can be a cause for bloating, however there are a lot of things that can cause bloating.
"When IBS occurs, the colon does not contract normally. instead, it seems to contract in a disorganized, at times violent, manner. The contractions may be terribly exaggerated and sustained, lasting for prolonged periods of time. One area of the colon may contract with no regard to another. At other times, there may be little bowel activity at all. These abnormal contractions result in changing bowel patterns with constipation being most common.
A second major feature of IBS is abdominal discomfort or pain. This may move around the abdomen rather than remain localized in one area.
These disorganized, exaggerated and painful contractions lead to certain problems. The pattern of bowel movements is often altered. Diarrhea may occur, especially after meals, as the entire colon contracts and moves liquid stool quickly into the rectum. Or, localized areas of the colon may remain contracted for a prolonged time. When this occurs, which often happens in the section of colon just above the rectum, the stool may be retained for a prolonged period and be squeezed into small pellets. Excessive water is removed from the stool and it becomes hard.
Also, air may accumulate behind these localized contractions, causing the bowel to swell. So bloating and abdominal distress may occur."

There is other research on bloating and distension in IBS from abdominal muscles.
But in IBS pain or discomfort is a must for a diagnoses, its more the whole picture in IBS then say just the symptoms of bloating. Normal people can bloat but they don't get major disress from it, especially on a regular basis.
SIBO can cause alabsorbtion of nutrients, which IBS does not.
Impaired intestinal gas propulsion in manometrically proven dysmotility and in irritable bowel syndrome.
CONCLUSION & INFERENCES: Patients with manometric dysmotility have markedly impaired intestinal gas propulsion. In IBS patients, impaired gas propulsion is less pronounced but associated with concomitant sensory dysfunction and poor tolerance of gas retention.

So altered motility in IBS can cause altered gas transit through the colon and bloating and distension, that on top of viceral hypersensivity.
Not everything about bacteria in the colon in that vidoes was about sibo. Some was just on foods and bacteria themselves.
This was on something I was going over years ago when the sibo and IBS research just started coming out.
I am trying to understand somethings in relationship to SIBO.
I posted here so you both may see it. I am looking into but am not sure about somethings that you guys can possibly help with.
Okay altered motlity can cause bacteria to enter the small bowel where it should not be really, at least in high counts, because its a pretty sterile environment. For the moment I am just looking at the altered motility reason for SIBO.
What are small intestinal bacteria overgrowth symptoms?
The symptoms of SIBO include:
excess gas, abdominal bloating and distension, diarrhea, and abdominal pain.
"A small number of patients with SIBO have chronic constipation rather than diarrhea. "
How does small intestinal bacterial overgrowth cause symptoms?
When bacteria digest food in the intestine, they produce gas. The gas can accumulate in the abdomen giving rise to abdominal bloating or distension. Distension can cause abdominal pain. The increased amounts of gas are passed as flatus (flatulence or farts). The bacteria also probably convert food into substances that are irritating or toxic to the cells of the inner lining of the small intestine and colon. These irritating substances produce diarrhea (by causing secretion of water into the intestine). There is some evidence that the production of one gas by the bacteriaâ€"methaneâ€"causes constipation.

Any Idea what those irritating substances are?
This means these are just in the wrong place and not specific or multiple pathogens?
A "classic" bacterial infection or a reaction to "all" the bacteria there themselves?
wrote to Dr Drossman on this and here is the reply.
*Any Idea what those irritating substances are?*
sorry its in bold type that is how he worte it into the email so I would see it was his answers.
"IT IS AN OVERSTATEMENT TO SAY THEY ARE "IRRITATING" SUBSTANCES AT LEAST IN THE SENSE OF BEING SOME TYPE OF TOXIN. THEY ARE NATURAL BYPRODUCTS OF DEGRADATION OF FOOD SUBSTANCES BY BACTERIA WHICH DON'T NORMALLY OCCUR IN THE SMALL BOWEL. SO WITH INCREASED BACTERIA IN THE SMALL BOWEL, THE BACTERIA ARE ABLE TO DIGEST SUGARS FOR EXAMPLE PRODUCING H2 AND CO2 FROM THE SUGARS WHICH ARE GASEOUS BUT WHICH ALSO HAVE OSMOTIC PROPERTIES, I.E. INCREASED PARTICLES THAT CAUSE SECRETION OF FLUID INTO THE BOWEL THUS CAUSING DIARRHEA. IT'S THE SAME PRINCIPLE AS USING NON ABSORBABLE SUGARS LIKE LACTULOSE OR SORBITAL TO TREAT CONSIPATION BY INCREASING FLUID IN THE BOWEL. IT'S JUST THAT WITHOUT BACTERIA IN THE SMALL BOWEL, IT DOESN'T HAPPEN AND THE FOOD SUBSTANCES GET ABSORBED. WITH INCREASED BACTERIA IT COMPETES FOR THE FOOD SUBSTANCES AND PRODUCES THE GAS AND DIARRHEA."
*This means these are just in the wrong place and not specific or multiple pathogens?*
CORRECT. HOWEVER, THERE IS GROWING INTEREST NOT IN THE AMOUNT OF BACTERIA BUT THE TYPE OF BACTERIA. CERTAIN BACTERIA CAN CAUSE SOME MILD INFLAMMATION OF THE BOWEL AND OTHERS PROTECT THE BOWEL FROM THAT POSSIBILITY. SO THERE IS "GOOD" AND "BAD" BACTERIA. POSSIBLY WHEN PEOPLE ARE TREATING PRESUMED SIBO (WHICH MIGHT NOT ACTUALLY BE HAPPENNING, BECAUSE THE TEST MAY BE INACCURATE) ANTIBIOTICS MAY HELP TO GET RID OF THE BAD BACTERIA AND THAT MAY BE WHY THEY ARE GETTING BETTER. THIS IS WHY SOME PEOPLE GET BETTER AFTER ANTIBIOTIC TREATMENT. BUT IT CAN ALSO GO THE OTHER WAY, I.E., ANTIBIOTICS HAVE BEEN SHOWN TO MAKE IBS WORSE AS WELL. THE OTHER IDEA IS TO USE PROBIOTICS WHICH CONTAIN "GOOD" BACTERIA (E.G., LACTOBACILLUS OR BIFIDOBACTERIA) WHICH REPLACE THE BAD BACTERIA, POSSIBLY REDUCE THE INFLAMMATION AND IMPROVE SYMPTOMS. SO THE ISSUE OF BACTERIA IN THE BOWEL IS MUCH MORE COMPLICATED THAN SIMPLE SIBO, BUT SIBO CAN BE A PART OF THE WHOLE PICTURE (THOUGH NOT THE WHOLE PICTURE FOR IBS).
