Bacterial, viral, and parasitic infections in the gastrointestinal tract often cause sudden symptoms like diarrhea, vomiting, dehydration, abdominal cramps, or fever. Not all GI infections resolve on their own, and persistent or severe cases require expert care. Dr. Vibhu Mittal, an expert in digestive infections, evaluates patients through stool analysis, blood tests, and endoscopic studies when necessary. His treatment focuses on targeted medications, hydration management, and preventive diet strategies to restore gut health. Dr. Vibhu Mittal also emphasizes identifying the source of infection—such as contaminated food, water exposure, or travel-related pathogens—to reduce recurrence. With proper guidance, patients recover faster and maintain a healthier digestive system.
