Your mesentery can also produce a protein called C-reactive protein CRP , which is a sign of inflammation. This new understanding of the mesentery and how it functions could be a game changer for how doctors understand and treat certain conditions.
This inflammation can lead to pain, diarrhea, and trouble absorbing nutrients from food. Fat cells in the mesentery can produce proteins that are associated with inflammation, including CRP. The mesentery is a newly classified organ in your abdomen. Mesenteric panniculitis is an inflammation of fatty tissue in your abdomen. Learn about symptoms, causes, risk factors, and treatments. The peritoneal space is between the abdominal wall and the organs it houses. This area is usually empty, but a buildup of fluid can result in….
At-home microbiome testing kits can be a first step. We look at these and give our recommendations for your overall gut health questions. Cholangitis is inflammation swelling in the bile duct. Treatment depends on your symptoms and whether you have chronic or acute cholangitis. Gastroparesis is a condition in which your stomach empties into your small intestine too slowly.
Learn about the best diet for gastroparesis and what…. Pancreatitis is inflammation of the pancreas and causes abdominal tenderness and pain. Learn more. What does a gastroenterologist do, and when should you see one?

Abstract In Crohn's disease bacteria could be detected in the adjacent mesenteric fat characterized by hypertrophy of unknown function.
Introduction In Crohn's disease a hypertrophy of the mesenteric fat adjacent to the inflamed intestinal segments represents a pathognomonic finding. Results Translocation of peptides and bacteria To evaluate small peptide translocation from the gut and their presentation particularly in the mesenteric fat tissue, fluorescent ovalbumin peptide FOva was administered orally to wild-type WT mice.

Consistent with these findings, the mRNA expression of proinflammatory cytokines and lipid anabolism genes was increased in the livers of inflamed MAT-removal mice.
MAT removal also injured the intestinal barrier and promoted intestinal inflammation.
