Frequently Asked Questions
How long does infectious colitis last?
Mild cases often improve in 3-7 days with proper hydration and rest. More severe infections may take 2-3 weeks to fully resolve, depending on the pathogen and treatment response.
Is infectious colitis contagious?
Yes. Many of the bacteria, viruses, and parasites that cause colitis can spread from person to person. Rigorous hand-washing and proper food safety help prevent transmission.
What is the ICD-10 code for infectious colitis?
The most common codes are A04.9 for bacterial colitis and K52.9 for unspecified noninfective colitis. Dr. Scott uses the correct code to guide treatment and billing.
How is infectious colitis treated?
Treatment includes rest, fluid and electrolyte replacement, dietary adjustments (BRAT diet), and-when indicated-antibiotics or antiparasitic medications under Dr. Scott's guidance.
When should I see Dr. Scott for colitis?
Schedule an appointment if diarrhea lasts more than 2 days, you notice blood in your stool, you have a high fever, or you show signs of dehydration (dizziness, reduced urine output).
Can I go back to work after having colitis?
Yes. You can usually return to work once you've been symptom-free (no diarrhea, vomiting, or fever) for at least 24 hours and are well-hydrated.
How do I avoid infectious colitis in Houston summers?
Avoid undercooked or street-vendor foods, drink bottled or properly treated water, and wash your hands thoroughly after using public facilities or before eating.
