A risky but often lifesaving surgery that removes damaged parts of the small intestine can leave patients facing a new threat: serious liver damage with no available treatment. Now, scientists have ...
Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that ...
Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the gastrointestinal tract while also trapping and disabling ...
Researchers have created “Smart Underwear,” a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a ...
Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and ...
Researchers studying over 8,400 colonoscopies discovered that having both adenomas and serrated polyps in the bowel can raise the risk of serious precancerous changes by up to five times. These two polyp types may represent separate cancer pathways ...
Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic fingerprint.” Some of the enzymes gather around ...
A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate ...
Popular acid reflux drugs such as Prilosec, Nexium, and Protonix may carry hidden risks when taken long term. A new study found that extended use disrupted iron and calcium levels in rats, changes associated with anemia and osteoporosis risk. ...
Training harder may do more than build muscle—it could transform your gut. Researchers found that intense workouts change the balance of bacteria and important compounds in athletes’ digestive systems. When training loads dropped, diet quality ...
A newly discovered bacterial duo may be the hidden cause of chronic constipation. The two microbes break down the colon’s protective mucus layer, leaving stool dry and hard — a problem traditional laxatives don’t fix. Parkinson’s patients, ...
A global study has uncovered a mysterious group of gut bacteria that shows up again and again in healthy people. Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help ...

Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread ...

Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the ...

Researchers discovered that 168 common chemicals can disrupt the growth of beneficial gut bacteria, with some also promoting antibiotic resistance. Many of these substances—found in food, water, ...

Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to ...

Scientists found that kale’s prized nutrients are hard for the body to absorb unless they’re eaten with oil. Cooking doesn’t improve absorption, but adding oil-based dressings—or even more ...

Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations ...

UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn’s ...

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue ...

Scientists have uncovered a surprising new pathway behind life-threatening food allergies. Instead of histamine, a different chemical called leukotrienes drives severe reactions in the gut. These ...

For decades, scientists have puzzled over why smoking makes Crohn’s disease worse but seems to protect people from ulcerative colitis. Now, researchers at RIKEN have discovered that smoking creates ...

Researchers have created plant-based microbeads that trap fat in the gut, helping rats lose weight without side effects. Unlike current drugs, the beads are safe, tasteless, and easy to mix into ...

UBC researchers revealed that gut bacteria can digest cellulose-based food thickeners, once thought indigestible, by using enzymes activated by natural dietary fibers. This discovery suggests these ...

A new global study reveals a striking post-pandemic surge in gut-brain disorders like IBS and functional dyspepsia. Researchers compared data from 2017 and 2023 and discovered sharp increases IBS up ...

A mysterious gut hormone may be behind many cases of chronic diarrhea, especially in people with undiagnosed bile acid malabsorption, a condition often mistaken for irritable bowel syndrome. ...

ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and ...

Chronic inflammatory bowel disease is challenging to treat and carries a risk of complications, including the development of bowel cancer. Young people are particularly affected: when genetic ...

New research conducted by an international consortium shows that IBD and related conditions are now spreading through developing regions in Africa, Asia, and Latin ...

'Biomarkers' may help to improve detection and treatment of gastrointestinal diseases such as gastric cancer, colorectal cancer, and inflammatory bowel ...

Researchers find high-fat diets set off metabolic dysfunction in cells, leading to weight gain, but these effects can be reversed by treatment with an ...

Feeding the gut acetate, paired with the right Bacteroides bacteria, led mice to shed fat without losing muscle. The combo pushed their metabolism into fat-burning mode, similar to fasting or a keto ...
