Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is an ongoing or chronic health problem that causes inflammation and swelling in the digestive tract. The irritation causes bleeding sores called ulcers to form along the digestive tract. This in turn can cause crampy, abdominal pain and severe bloody diarrhea.

What is Ulcerative Colitis?

Ulcerative colitis is a chronic condition that affects the large intestines, particularly the colon. It is classified as one of the two inflammatory bowel diseases along with Crohn’s disease.

Inflammatory bowel disease linked to elevated risk of psychiatric disorders

Patients with inflammatory bowel disease (IBD) face a significantly higher risk of psychiatric disorders starting two to three years before diagnosis and lasting up to a decade after, according to a nationwide study to be published in Clinical Gastroenterology and Hepatology.

New genomic approach links rare immune cells to autoimmune disease risk

Much of how genetic risk leads to disease has remained hidden. In many cases, genetic variants linked to disease do not act on nearby genes along the chromosome.

Two microscopic parasites cause widespread diarrheal illness across America

You've seen the alarming headlines about parasites causing "explosive diarrhea" across the U.S. Two microscopic parasites – cyclospora cayetanensis and cryptosporidium – can both cause prolonged gastrointestinal illness, including watery diarrhea, stomach cramps, and dehydration.

Global childhood IBD trends reveal unequal progress in diagnosis and survival

An analysis of GBD 2021 estimates across 204 countries and territories found that global deaths from early-onset IBD fell by approximately 71% among children younger than 10 between 1990 and 2021. However, estimated incident and prevalent case numbers rose while the age-standardized incidence rate remained broadly stable, with persistent socioeconomic and regional inequalities.

Early PFAS exposure linked to childhood intestinal inflammation

Researchers at the Icahn School of Medicine at Mount Sinai have found that exposure to per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," during pregnancy and early life is associated with increased intestinal inflammation during childhood.

Dysregulation of immune regulator NF-κB drives major human diseases

NF‑κB controls genes involved in inflammation, immunity, cell survival, and proliferation. Triggered by cytokines (TNF‑α, IL‑1β), microbial products, or cellular stress, it translocates to the nucleus and induces pro‑inflammatory mediators.
