https://medicalxpress.com/gastroenterology-news/ en-us Latest medical news and research in Gastroenterology Researchers at the University of Cologne, University Hospital Cologne and the Max Planck Institute for Metabolism Research have developed a method that, for the first time, enables damage to individual cells to be precisely quantified. The method uses molecular markers—specifically gene expression—and enables detailed analysis of disease progression in individual tissue samples, such as a biopsy. https://medicalxpress.com/news/2026-08-gene-markers-quantify-individual-kidney.html Fri, 21 Aug 2026 14:40:03 EDT news706537561 Researchers from the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have identified a previously unknown mechanism by which a particularly aggressive form of colon cancer evades the immune system. https://medicalxpress.com/news/2026-08-highly-aggressive-colon-cancer-evades.html Thu, 20 Aug 2026 17:20:03 EDT news706455684 It's widely understood that the microbiome—especially microbes found in the mouth and the gut—can have a profound effect on health. In a study published in the journal Cell Host & Microbe on Aug. 20, researchers report that by analyzing the makeup of oral microbes, they may be able to detect signals associated with gastric (stomach) and colorectal cancer. These findings could lead to the development of new, less invasive screening tests for gastrointestinal cancers. https://medicalxpress.com/news/2026-08-simple-mouth-stomach-colorectal-cancer.html Thu, 20 Aug 2026 11:00:08 EDT news706281781 The liver is a jack-of-all-trades and a master of all. From removing harmful substances and secreting bile to metabolizing proteins, carbohydrates and fats and managing the immune system, the liver does it all. As we age, liver cells undergo major structural changes, making the body prone to metabolic liver diseases such as fatty liver and inflammation, which, over time, can increase the risk of liver cancer. https://medicalxpress.com/news/2026-08-citrus-compound-reverses-liver-aging.html Thu, 20 Aug 2026 10:40:03 EDT news706437945 Mayo Clinic researchers have estimated the risk that pancreatic cysts with worrisome or high-risk features will progress to pancreatic cancer or advanced precancerous changes within three years. The findings, published in Gastroenterology, could help physicians and patients better assess risk and make more informed decisions about whether to monitor a cyst or consider surgery. https://medicalxpress.com/news/2026-08-cancer-patients-pancreatic-cysts-advancing.html Thu, 20 Aug 2026 09:00:01 EDT news706352221 Why does inflammation persist in Crohn's disease and ulcerative colitis, even as the body is trying to bring it under control? Researchers in Kiel and the United States have identified a mechanism that offers a surprising answer: Inflammation itself disrupts a key metabolic pathway needed to supply the intestinal lining with energy. https://medicalxpress.com/news/2026-08-crohn-disease-ulcerative-colitis-inflammation.html Wed, 19 Aug 2026 14:40:01 EDT news706368002 Every RNA virus—from stomach bugs and influenza to measles and the common cold—has its own story to tell, with a unique combination of symptoms, transmission rates, duration and chemical blueprint. https://medicalxpress.com/news/2026-08-norovirus-vaccine-approach-strategies-rna.html Wed, 19 Aug 2026 13:00:06 EDT news706358581 Crohn's disease, a condition characterized by widespread inflammation in the gut, may arise from a weakened immune response, according to new research from the University of Toronto's Temerty Faculty of Medicine. https://medicalxpress.com/news/2026-08-immune-defect-crohn-disease-motion.html Tue, 18 Aug 2026 17:40:05 EDT news706287121 Approximately 65% of U.S. adults report consuming one or more sugar-sweetened beverages every day. Mass General Brigham Cancer Institute researchers found that consuming these drinks daily was associated with an increased risk of developing gastric cancer, while artificially sweetened beverages were not associated with an increased risk. Results are published in the journal Gastro Hep Advances. https://medicalxpress.com/news/2026-08-people-consume-sugar-sweetened-beverages.html Mon, 17 Aug 2026 12:40:11 EDT news706189144 A study published in JCI Insight and led by Northwestern Medicine scientists has uncovered new clues about why people with systemic sclerosis, also known as scleroderma, frequently develop debilitating esophageal complications. https://medicalxpress.com/news/2026-08-cellular-clues-complications-scleroderma.html Mon, 17 Aug 2026 07:20:07 EDT news706164301 Researchers at Baylor College of Medicine and Texas Children's Hospital have uncovered an intervention that could potentially improve outcomes for children with malnutrition, a condition that contributes to nearly half of all deaths among children younger than 5. The study appears in the Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2026-08-intervention-potentially-outcome-children-malnutrition.html Thu, 13 Aug 2026 18:00:07 EDT news705859921 A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could reduce Alzheimer's risk, according to a new study published in Nature Communications https://medicalxpress.com/news/2026-08-gut-alzheimer.html Thu, 13 Aug 2026 14:40:01 EDT news705843563 An international research team coordinated by the Berlin Institute of Health at Charité (BIH) has created the most comprehensive single-cell atlas of the human pancreas to date. As part of a Human Cell Atlas project led by Professor Roland Eils, the team analyzed more than 4 million cells and cell nuclei from pancreatic tissue samples donated by 57 individuals. https://medicalxpress.com/news/2026-08-cell-atlas-reveals-plasticity-human.html Thu, 13 Aug 2026 13:40:05 EDT news705843403 Calls to poison centers involving liver injuries caused by medications, supplements, alcohol and other substances jumped nearly 400% between 2000 and 2024, according to a new study from UVA Health published in Clinical Gastroenterology and Hepatology. https://medicalxpress.com/news/2026-08-poison-center-liver-injuries-acetaminophen.html Thu, 13 Aug 2026 06:00:02 EDT news705765282 Organs don't just grow in early life; they can change in response to physiological or environmental challenges in adulthood. Researchers have now identified an active role for the intestinal muscles in remodeling the gut after reproduction. https://medicalxpress.com/news/2026-08-female-gut-muscles-reshape-demands.html Wed, 12 Aug 2026 11:40:03 EDT news705753421 Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown signaling pathway, opening new possibilities for treating advanced fatty liver disease. https://medicalxpress.com/news/2026-08-appetite-suppressing-hormone-liver-inflammation.html Mon, 10 Aug 2026 16:20:08 EDT news705587701 Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of intestinal cells that have been lost and renew themselves. https://medicalxpress.com/news/2026-08-molecular-gut-colorectal-cancer-hijacks.html Wed, 05 Aug 2026 18:20:03 EDT news705165901
