Microbiome Disruption:

• Bacterial Die-off: Radiation kills beneficial gut bacteria
• Pathogen Overgrowth: Harmful bacteria proliferate in damaged gut
• Metabolite Changes: Altered production of beneficial compounds
• Immune Suppression: Reduced gut immune function

Clinical Presentation

Acute Radiation Enteritis (During/Shortly After Treatment):

• Diarrhea: Watery, frequent stools
• Nausea and Vomiting: Common side effects
• Abdominal Pain: Cramping and discomfort
