There is a force acting on your bowels that may be causing some people serious irritation.

Brennan Spiegel is a gastroenterologist at Cedars-Sinai hospital in Los Angeles and he has outlined a new hypothesis about the causes ofIBS.

According to a paper published in the American Journal of Gastroenterology, the body's inability to manage gravity is the cause of Irritable Bowel Syndrome.

Our bowels are like a sack of potatoes that we have to carry for the rest of our lives.

If our body's usual management of gravity doesn't work out, our diaphragm can slip down and cause issues with our GI tract.

"Our nervous system evolved in a world of gravity, and that may explain why many people feel butterflies when anxious," says Spiegel.

It's curious that these 'gut feelings' also happen when falling towards Earth, like when dropping on a roller coaster or in a turbulent airplane. When we experience a dangerous fall, the nerves in the gut warn us. It's just a hypothesis, but people withIBS might be prone to over-predicting G-force threats.

Spiegel's hypothesis is easy to test and doesn't exclude other theories of the disease.

There is no definitive test forIBS and its symptoms are very variable. The syndrome is often made a diagnosis of exclusion.

When other disorders that can cause gut symptoms have been ruled out, patients are told they have Irritable Bowel Syndrome.

About 10 percent of the world's population suffer from the syndrome, and many scientists are trying to figure out why.

He thinks that gravity might be the cause of all these symptoms.

There is a possibility that a gut-to-brain interaction disorder could be triggered by a disorderly response to gravity. The impact of squashing the intestines could be worse.

There are so many different explanations that I wondered if they could all be true at the same time.

All of the theories point to gravity as a unifying factor. It was strange at first, but as I ran it by my colleagues, it made sense.

If the body struggles to grapple with gravity, it could explain why physical therapy and exercise work so well to relieve symptoms of Irritable Bowel Syndrome.

Serotonin tends to be elevated in people with Irritable Bowel Syndrome.

Serotonin is a neurotransmitter that is primarily produced in the gut to regulate our bowel movements and also our mood, but too much of it can cause a lot of problems. Our blood pressure is regulated in response to gravity.

Your body might not be able to function if you don't have serotonin.

It is argued that a form of gravity failure is dopaminergic Serotonin.

People can suffer from depression, anxiety, and chronic fatigue when the serotonin biology is not normal. It is possible that these are forms of gravity insensitivity.

Chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ ME) is a chronic and disabling sickness without a cause or cure and it often crosses over with Irritable Disk Syndrome. A sudden drop in blood pressure, fatigue, dizziness, and a racing heart can be caused by standing up.

Lower back pain, headaches, dizziness, and POTS, which is when blood pressure plummets after a person rises, are some of the symptoms that cross over with Irritable Bowel Syndrome.

The body can't properly manage the force of gravity.

Siegel doesn't think the gravity hypothesis is a real thing. He hopes it will encourage more research and treatment of the disease.

Siegel says the relationship of gravity and fish to water is similar.

Our existence is shaped by it, yet we don't notice its influence on the nature of our existence.

Maybe it's been a while since we considered it.

The study was published in a medical journal.
