There isn’t any official trigger for irritable bowel syndrome (IBS), however for one gastroenterologist, the reply has been proper below our noses. A evaluate revealed right this moment in The American Journal of Gastroenterology posits that the all-too-common ailment is attributable to the forces of gravity. The unconventional speculation suggests the human physique has advanced to dwell with this common power, and when our capacity to handle gravity falters, it will possibly have dire ramifications on our well being.
“Our relationship to gravity is somewhat bit like a fish’s relationship to water,” says Brennan Spiegel, a gastroenterologist at Cedars-Sinai Medical Middle in Los Angeles and writer of the brand new paper. “The fish advanced to have a physique that survives and thrives in water, even when it could not realize it’s in water to start with.” Equally, Spiegel explains that whereas we aren’t at all times aware of gravity, it’s a relentless affect on our lives. For instance, our early human ancestors advanced to develop into bipedal organisms, spending two-thirds of their lives in an upright place. However standing erect would trigger gravity to continuously pull our physique system down towards the bottom, which means organs and different bodily methods will need to have a plan in place to handle and resist gravitational forces. (For instance, mammalian brains have advanced methods to sense altered gravity situations.)

Spiegel says he thought concerning the gravity speculation in relation to IBS when visiting a sick member of the family at an assisted residing middle. Mendacity in mattress for a lot of the day, he seen a rise in GI issues throughout her keep, together with constipation, bloating, and belly ache, making him consider whether or not mendacity down all day modifications an individual’s relationship to the power of gravity. “Why is it that she’s not in a position to transfer her intestines in addition to she might earlier than,” he first questioned.
Consider the GI tract as a sack of potatoes. People internally lug round this sack their entire lives, although Spiegel argues that some individuals’s physique compositions are higher suited to hold that sack round higher than others. However in response to Newton’s Third Regulation (for each power in nature there may be an equal and reverse response), as a result of gravity is pulling our physique down, our physique’s will need to have “antigravity” mechanisms in place to stabilize organs. This assist comes from musculoskeletal buildings just like the backbone and mesentery that works as an inside suspension system to carry the intestines in place. What’s extra, the rib cage together with the backbone helps to safe the place of the diaphragm, which acts as a ceiling mount to droop organs within the upright belly cavity. All collectively, these buildings work as a crane to stabilize and preserve the organs in place.
However what occurs when the antigravity mechanisms in our physique fail? You’ll see signs similar to those that have IBS, in response to the analysis paper. When the musculoskeletal system will not be aligned with gravity, it’s not able to fully resisting this power of attraction. The mismatched pressure between engaging and repulsive forces would theoretically trigger stress within the physique, leading to muscle cramping and ache from being unable to correctly assist the contents within the stomach. Moreover, extra strain on the backbone from attempting to stabilize sagging buildings would trigger intense again ache. Lastly, if the belly crane begins to sag and loosens its maintain, the pull of gravity would trigger the organ to maneuver misplaced, pushing the GI tract ahead and giving little area for meals to maneuver out and in of the tract. All of those modifications could compound in IBS signs.
One level Spiegel emphasizes is that the gravity speculation will not be meant to disprove different concepts—two widespread ones being that IBS is attributable to modifications within the intestine microbiome or from elevated serotonin ranges—however relatively, a approach to tie in all them right into a concise clarification.
“Intestines fall below the power of gravity, and so they can develop an issue the place they kink up nearly like a twisted backyard hose that makes it exhausting for water to get by way of,” Spiegel says. “Because of this, they get bacterial overgrowth, and so they get belly ache and gassiness.”

Julie Khlevner, a gastroenterologist on the NewYork-Presbyterian Morgan Stanley Kids’s Hospital who was not affiliated with the analysis, says that whereas the gravity speculation is much less typical than different prevailing theories for IBS, it has been beforehand used to elucidate different ailments like amyotrophic lateral sclerosis. “Though [it’s] thought frightening and theoretically suitable with the scientific manifestations of IBS, it stays in its hypothetical stage and requires additional analysis,” she cautions. “For now, the at the moment accepted ideas in pathophysiology of IBS [alterations in the bidirectional brain-gut-microbiome interaction] will stay the pillars for improvement of focused therapies.”
If Spigel is true about his rationale, he could possibly be onto one thing greater. Understanding how gravity alters our bodily capabilities might assist discover solutions on why sure workout routines, resembling yoga and tai chi, can relieve GI signs by strengthening musculoskeletal muscular tissues and the anterior belly wall. Or why individuals expertise extra abdomen issues at excessive altitudes like when climbing up mountains, or extra typically, why ladies are disproportionately affected by IBS. Spiegel already has an evidence for the final problem (he says ladies have extra elastic inside buildings than males, together with floppier and longer colons which might be extra inclined to the pull of gravity), however he’s hoping others will pursue the identical line of labor and assist carry reduction to the hundreds of thousands of individuals residing with IBS on a regular basis.
