OK class, let’s settle down…
At first, the subject may seem a bit frivolous, but it is important enough that NASA studied it, and it truly can be a source of tremendous anxiety and vulnerability for some of us. Everybody does it, but the rules vary widely.
“Gas” can be a source of social or physical discomfort. It can vary from person-to-person, or change in amount or character with conditions. The history of the subject goes back as far as there have been adolescent males and females on first dates (ok, I made that up, but it’s probably true). Geoffrey Chaucer, known as the “Father of English literature,” wrote about it in the “Canterbury Tales,” and Ben Franklin wrote a treatise called “Fart Proudly” long before “South Park.” The original whoopee cushion is an ancient device.
Luckily, for many of us, opportunity exists to use this problem as part of our journey to learn more about our bodies, as well as our lifestyles. Patients often find the hardest step is just acknowledging the issue and discussing it with supporters, family members, peers or colleagues. We also have to admit that there will always be some gas, no matter how well we may follow our body’s rules!
Many patients note some change in their amount, timing and character of their flatus after surgery. Usually, this is a temporary issue, but it can be quite concerning. Severe malabsorptive procedures such as duodenal switch or distal gastric bypass are more frequently associated with complaints.
Changing dietary intake is certainly one of the major causes of altered flatus or flatulence (which comes out of your bottom), as opposed to borborygmus (burping/belching). Certain foods result in more sulphur compounds in the gas and create a worse smell. Carbonation is usually absorbed into the bloodstream, and the body will expel a fair amount of it via your exhaled breath. The altered bowel motility and absorption as a result of weight-loss surgery also can result in more or smellier gas.
Noise associated with gas can be from the abdomen (bowel sounds) or with the passage of gas through the anus (or an ostomy). While the buttock can make some noise, most is from the internal sphincter.
Strategies to Reduce Amount, Odor or Control Timing of Farts Include:
Remember, part of what makes us laugh about this is the social discomfort we all have with gas. Again, the most important message is to give your body and gut time to adapt. The first year after weight-loss surgery is often very different from later years, and some real change occurs in the ability of the gut to absorb at various locations.
This article is just an overview, and there is some useful medical literature, but not much. The Wikipedia entry is a worthwhile starting point for further information. Thanks also to Michelle Henderson, RN, for input on this subject. She is experienced in wound and ostomy care and has helped many patients with complex intestinal problems.
