Not dairy at least for the beginning. It's all about treating small intestinal bacterial overgrowth. The dietician is thinking that with the combo of colonoscopy preps and antibiotics wiping out both good and bad gut flora, plus slow transit due to painkillers (allowing bad bacteria to flourish in the small intestine) I may have an overgrowth of unwanted gas producing bacteria in the small intestine. This could also explain the stomach pain and loose stools.
The diet starves the bad bacteria of all sugar compounds - that means all carbohydrates including fruits and many vegetables, and sugars like lactose in dairy (so anything with an -ose ending, galactose, glucose, fructose,) as well as sugar alcohols like artificial sweeteners (end in -ol, malitol, sorbitol, xylitol, etc). The bacteria begin to die off quickly when they have no sugar to consume.
Then in the next few weeks the diet is a little more lenient - and you take an antimicrobial to kill off the rest of the bacteria. Because you have already starved them, the die off (and therefore discomfort) is minimal from the antimicrobials. The diet at this stage is continued for three months.
When the antimicrobials are done, probiotics (GOOD bacteria) and a prokinetic agent (like senna, to keep the intestines moving) are added to keep the bad bacteria away.

I've suspected that SIBO may be a problem for me as I seem to have stomach cramps about an hour after eating and getting worse onwards, and then difficulty having a bm until the next morning when my system dumps everything - it seems as though my food moves slowly through the small intestines and then too rapidly through the large intestine.
SIBO is often related to fat malabsorption (causing loose stool), B12, D and iron deficiency (all of which I'm at the bottom of the range for - below the recommended level for B12). I have all these problems so it seems like a good fit. The breath test diagnoses it - you fast then the byproduct of the bacteria is measured in your breath. You then drink a sugar liquid, and measure your breath in intervals afterwards, to see if the byproduct has increased significantly compared to baseline levels. If so, SIBO is a possible culprit.
It may or may not work but my diet is very high in carbs now, and if anything it will be very healthy so not too much downside.
I could point you towards some good scientific literature I've found on the subject if you're interested.
