Anxiety Can Be Dangerous to the Digestive System

A diet packed with processed foods isn’t the only thing that can have a negative impact on the digestive system.

Researchers from Brigham Young University (BYU) found that stress could be just as harmful to the human being body as a nutritional poor diet.

The experts found out that when feminine mice were exposed to stress, their gut microbiota — the microorganisms essential to intestinal and metabolic health — morphed to look like the rodents had been eating a high-fat diet.

“Stress can be harmful in a lot of ways but this research is fresh in that it ties stress to female-specific changes in the gut microbiota, “ BYU professor of microbiology and molecular biology Laura Bridgewater said in a statement. “We sometimes think of stress as a purely psychological phenomenon but it causes distinct physical changes. “

The team performed an experiment on a big group of eight-week old mice and exposed half of the men and half of the females to a high-fat diet. After 16 several weeks, all of the mice were exposed to slight stress over the course of 18 days.

Microbial DNA from the mice’s fecal pellets were removed before and after the stress to test how a gut microbiota was afflicted. They also measured mouse anxiety based about how much and where the rats traveled in an open field arena.

After analyzing the results, the researchers discovered males over a high-fat diet exhibited more anxiety than females on the high-fat diet. Males on the high-fat diet also demonstrated decreased activity in response to stress.

However, stress only caused the belly microbiota composition to shift in female mice as if they were on a high-fat diet.

“In world, women generally have higher rates of depression digestive system and panic, which are linked to stress, “ Bridgewater said. “This study suggests that any source of the gender discrepancy may be different ways gut microbiota responds to stress in males compared to. females. “
