Gastroenterology & Digestive Health Resource Center
Gastrointestinal bleeding and IBD scores, IBS and diarrhea tools, pancreatitis assessment, acid-suppression and H. pylori resources, endoscopy and colorectal-cancer content, microbiome updates, GI drug tables, and cross-links to GlobalRPh Hepatology resources.
Clinical background
GI symptoms often require both pattern recognition and disease-specific risk assessment
Gastroenterology spans disorders of motility and gut–brain interaction, mucosal inflammation, infection, bleeding, pancreatic and biliary disease, colorectal neoplasia, malabsorption, medication effects, and digestive manifestations of systemic disease. Similar symptoms can arise from very different mechanisms, making clinical context as important as any individual score or calculator.
This updated portal organizes GlobalRPh’s established GI calculators, gastrointestinal drug tables, newer 2025–2026 articles and selected guideline resources by bedside problem. Liver-related scores remain cross-linked here because they have historically lived in the Gastroenterology calculator collection, while the dedicated Hepatology portal remains the preferred location for broader liver disease content.

IBS Next-Generation Therapies
GlobalRPh’s newer IBS review brings the section beyond the older Rome and medication pages by examining low-FODMAP approaches, neuromodulators, digital cognitive behavioral therapy and microbiome-oriented interventions. It pairs naturally with the Rome IV criteria and the existing IBS treatment resources.
H. pylori: First-Line Failure & Salvage Therapy
The newer GlobalRPh H. pylori article addresses antibiotic resistance, treatment failure and salvage regimens, giving users a current clinical companion to the older H. pylori drug table.
Core GlobalRPh calculators
Gastroenterology & Hepatology scoring tools
The original portal contains a large calculator library. The revised page groups the tools by clinical question so users do not have to scan one long list.
IBS, IBD & diarrhea
GI bleeding & pancreatitis
Rome III remains available as a historical diagnostic framework
The current Gastroenterology portal links both Rome III and Rome IV. We are keeping the older Rome III tool available for historical and research-context use, while Rome IV is displayed first for the contemporary IBS diagnostic framework.
Looking primarily for liver-disease resources?
Cirrhosis, alcohol-associated liver disease, transplant scoring and MASLD overlap with Gastroenterology, but GlobalRPh also maintains a dedicated Hepatology section. We are keeping liver scores visible here until that section receives the same comprehensive portal update.
IBD, IBS & bowel disorders
Inflammatory bowel disease, disorders of gut-brain interaction and bowel symptoms
Irritable bowel syndrome
Crohn’s disease
Ulcerative colitis & bowel symptoms
Upper gastrointestinal bleeding
Pre-endoscopic risk, clinical outcomes and endoscopic stigmata
Initial risk assessment

Symptoms & supportive therapy
Endoscopy, colorectal cancer & surveillance
Colonoscopy quality, AI-assisted detection, surveillance and emerging endoscopy
GlobalRPh has developed a substantial recent endoscopy library that was not visible from the older Gastroenterology portal.

Hepatology crossover
MASLD, cirrhosis, alcohol-associated liver disease and transplant scoring
Liver scores historically account for a large portion of the GlobalRPh Gastroenterology calculator library. We are retaining those links here while making the separate Hepatology destination much more visible.
Cirrhosis & transplant-related scores
Alcohol-associated hepatitis
Gastrointestinal pharmacotherapy
GlobalRPh GI drug-table library
The original portal already contains a useful medication library. It is reorganized below by clinical purpose.
Upper GI & acid-related disease
Bowel symptoms & motility
Inflammatory bowel disease
Microbiome, recurrent C. difficile & metabolic GI research
One of the fastest-growing areas in the GlobalRPh GI library
GlobalRPh gastroenterology article library
Recent and established GI reading
The previous portal primarily surfaced 2024 material. This updated library brings forward the stronger 2025–2026 Gastroenterology content while preserving access to the complete archive.
GlobalRPh gastroenterology video
Existing digestive-health videos now surfaced on the portal
The old Gastroenterology portal had an empty video area even though GlobalRPh’s main video library already includes GI and microbiome content.

Planned GlobalRPh updates
Areas we’re continuing to improve in the Gastroenterology library
GlobalRPh has maintained many of these GI calculators and drug tables for years while diagnostic criteria, endoscopic practice, IBD therapy, transplant scoring, H. pylori resistance patterns and liver-disease treatment have evolved. As we work through this section, we plan to preserve the practical tools while updating the clinical logic, reference base and safety context around them.
Pages we plan to refresh
- MELD / MELD-Na: this is one of our highest-priority updates. The current transplant-allocation MELD formula changed in July 2023. We plan to rebuild the GlobalRPh calculator around the current variables and clearly identify older MELD and MELD-Na formulas as historical.
- Rome III / Rome IV: we plan to make Rome IV the primary IBS diagnostic page, retain Rome III as a historical/research reference, and improve the explanation of disorders of gut-brain interaction and red-flag features that require evaluation outside a symptom-based framework.
- IBS Treatment Options: the existing page contains useful material but an older reference base. We plan to incorporate current dietary therapy, soluble fiber, secretagogues, rifaximin, neuromodulators, digital CBT, pelvic-floor considerations and evidence around microbiome-directed approaches.
- IBD Drug Table / TNF Inhibitors: we plan to expand this beyond older TNF-centered treatment pathways to reflect current biologics, small molecules, treatment sequencing, treat-to-target concepts, preventive care, infection screening and the 2025 Crohn’s and ulcerative-colitis guidelines.
- Crohn’s and ulcerative-colitis scores: we plan to preserve CDAI, Harvey-Bradshaw and Mayo scoring while making it clearer how symptom scores relate to biomarkers, endoscopy, imaging and modern treatment targets.
- H. pylori Drug Table: we plan to rebuild the regimen table around the 2024 ACG guideline, antibiotic resistance, optimized bismuth quadruple therapy, susceptibility-guided therapy, rifabutin/vonoprazan options where appropriate and confirmation of eradication.
- PPI / H2 / antacid tables: we plan to update currently marketed products, comparative acid suppression, indications, interaction concerns, long-term-use considerations and the evolving role of potassium-competitive acid blockers.
- Upper GI bleeding scores: we plan to retain Glasgow-Blatchford, Rockall and Forrest classification while updating their clinical context, pre-endoscopic triage, transfusion strategy, PPI use, timing of endoscopy and anticoagulant-management links.
- Ranson’s Criteria: we plan to preserve this historically important pancreatitis score while adding contemporary acute-pancreatitis context, including risk assessment, fluid strategy, early feeding, biliary disease evaluation and when higher-acuity monitoring is warranted.
- Laxatives / constipation therapy: we plan to update the older drug table around current chronic idiopathic constipation pharmacotherapy, secretagogues, prokinetic therapy, opioid-induced constipation and appropriate evaluation of secondary causes.
- Antidiarrheals / antispasmodics / anticholinergics / antiemetics: we plan to re-check current product availability, contraindications, geriatric considerations, QT risk, drug interactions and syndrome-specific use.
- Alcohol-associated hepatitis scores: we plan to retain ABIC, AHHS, GAHS, Lille and Maddrey while updating terminology, treatment context, current guideline links and the distinction between prognostic scoring and treatment eligibility.
- MASLD / MASH tools: we plan to add a stronger noninvasive fibrosis-assessment pathway and connect future tools with current AASLD guidance, metabolic-risk assessment and newer pharmacotherapy.
- Endoscopy content: we plan to continue expanding the portal around modern surveillance intervals, bowel-preparation quality, advanced endoscopic resection, AI-assisted detection and post-polypectomy follow-up.

Historical GI content remains accessible while we work through the section
We are keeping established scores and older drug tables accessible when they still have clinical, educational or historical value. The planned-update section identifies where we intend to refresh terminology, evidence, product availability, scoring logic or guideline context without breaking longstanding GlobalRPh links.
