Hi Kerrie, sorry to here your in distress and thanks for your kind comments. On learning all this just go slow its very complex and take a while sometimmes reading the abstracts again and again, but in time it becomes easier and it is very benefical in the long run.
First HT has been shown to normalize bowel movemnts in IBS, how that works exactly is not understood yet, even though they do know some reasons, it seems to go deeper then they have been able to figure out yet.
Next, all kinds of things here though, one they don't totally understand bloating in IBS and are studying it more, not all of it is from gas however. Some of it might have to do with muscles and perrhaps a big part with diet, but there is much more to it then that even. Also like gas it a hard symptom to treat in IBS, however HT has been shown to reduce it and I will point you in the direction to read that and see a graph.
Here is some info and studies on it.

Review article: bloating in functional bowel disorders.

Bloating is a frequently reported symptom in functional bowel disorders. It usually occurs in combination with other symptoms, but may also occur in isolation. The severity of bloating tends to worsen during the course of the day and improves overnight. Although frequently considered to be a subjective phenomenon, recent studies have shown that bloating is associated with a measurable increase in abdominal girth. The pathophysiology of bloating remains elusive, but the evidence supports a sensorimotor dysfunction of the bowel. The possible mechanisms include abnormal gas trapping, fluid retention, food intolerance and altered gut microbial flora. Further studies are needed to define the sensorimotor abnormalities associated with bloating, which might be segmental and transient rather than generalized and persistent. The lack of understanding of this symptom is paralleled by a limited availability of therapeutic options. Conventional medications used in functional bowel disorders are not helpful and may indeed worsen the symptoms. In future, new drugs with activity against serotonin and kappa receptors, or novel approaches such as the use of exclusion diets, probiotics and hypnotherapy, may prove to be useful.

Sensation of bloating and visible abdominal distension in patients with irritable bowel syndrome.

OBJECTIVES: Abdominal bloating and distension are common symptoms of irritable bowel syndrome (IBS). The postulated pathophysiological mechanisms underlying these symptoms include increased production, retention, or perception of gas or luminal contents. The aims of this study were to prospectively compare the prevalence of, and clinical factors related to, bloating and distension in an IBS patient population. METHODS: A total of 714 consecutive patients who met Rome I criteria for IBS were prospectively surveyed, and were classified as having bloating alone (B) or bloating and distension (B+D) based on a comprehensive bowel symptom questionnaire. GI, extraintestinal, and psychological symptoms, as well as health-related quality of life measures were also assessed using validated survey instruments. RESULTS: A total of 542 IBS patients (76%) who reported abdominal bloating were studied. Of these, 132 patients fulfilled criteria for the B group, whereas 410 patients fulfilled criteria for the B+D group. There was a significantly different gender distribution in the B and B+D groups (female:male ratios, 1.4:1 and 2.8:1, respectively p < 0.02). There was also a significantly different bowel habit subgroup distribution, with a greater predominance of constipation in B+D group and of diarrhea in the B group (p < 0.03). Both groups were similar in other clinical parameters, including progressive worsening of symptoms during the day, and relief by passing stool or gas. Both bloating and distension worsened when other abdominal symptoms worsened. Abdominal distension was associated with greater symptom severity and less diurnal variation in symptoms, and was less often perceived as associated with food intake. CONCLUSIONS: Bloating and visible abdominal distension may arise from two distinct but interrelated physiological processes. Although the sensation of bloating may be related to enhanced sensitivity to visceral afferent stimulation, abdominal distension in more severely affected patients may be related to triggering of a visceromotor reflex affecting the tone of abdominal wall muscles.

one more on bloating mechanisms. This is a good resource in general and worth looking over.
Gas and Bloating

On this page is a graph on bloating and HT. I personally still get bloated, but noot half as much as I use to and sometimes I do because I don't always eat perfectly in regards to my IBS, so sometimes yes I can trace it to foods, one other way also maybe from lack of eating right not just foods, but eating schedules and keeping the gut working and food in it.
Here is a graph of abdominal distension in IBS pre HT and after HT. This is also a public site from an expert worrth reading on HT for IBS.

Hope this helps some and feel free to ask any question you want no question to me are dumb when it comes to IBS so know worries on that end. 
A probiotic may help this also.
because in IBS also there can be alter gut transit, it may trap gas in the colon and cause pain and bloating, by gaining better transit, it may cause you to fart, but it may also at the same time release gas pressure on the colon by expelling it, so this maybe one way HT helps this problem, although relaxing muscles and muscle tension probably helps as well and altering gut perception a part too.
The yoga may also help this and excersise as well also for better gut function and transit time.
