Gastrointestinal Infections
What Are Gastrointestinal Infections?
Gastrointestinal infections occur when bacteria, viruses, or parasites affect the stomach and intestines. Common causes include contaminated food or water, travel exposure, antibiotic use, or contact with infected individuals.
Common symptoms include
Abdominal pain or cramping
Fever or chills
Drainage from a wound or surgical site
Nausea, vomiting, or diarrhea
Early Treatment
Why Early Treatment Matters
Most GI infections resolve quickly, but some can become serious—especially in children, older adults, and patients with weakened immune systems. Without proper care, they may lead to:
- Severe dehydration
- Persistent diarrhea or malnutrition
- Spread of infection to others
- Long-term gut health issues (including microbiome imbalance)
Prompt evaluation by a board-certified Colorado Infectious Disease specialist can ensure you receive the right treatment and prevent complications.
How we treat
How We Treat Gastrointestinal Infections
Dr. Coulter provides individualized care using:

- Supportive care to restore hydration and electrolytes
- Guidance on safe foods and prevention of reinfection
- Collaboration with gastroenterologists if specialized care is needed

FAQs
Frequently Asked Questions
Do all GI infections require antibiotics?
Not always. Many viral and mild bacterial infections resolve on their own. Dr. Coulter determines whether targeted treatment is necessary.
When should I see a Colorado Infectious Disease doctor instead of my primary care physician?
If symptoms are severe, prolonged, or recurrent—or if stool tests show unusual bacteria, parasites, or resistant infections—it’s time to see a specialist.
Can GI infections cause long-term gut problems?
Yes. Some infections disrupt the microbiome, leading to conditions like post-infectious IBS or dysbiosis. Infinity ID provides microbiome support as part of recovery.
