Medical Details

Transmission

Colitis itself is a symptom/condition. Infectious causes like Whipworms or Giardia are transmissible, but "Stress Colitis" or dietary intolerance is not.

Progression & Stages

Acute colitis appears suddenly, often after a stressful event or dietary indiscretion. Chronic colitis persists for weeks and requires diagnostic workup to find the underlying immune or physical cause.

Diagnosis

Diagnosis involves fecal exams for parasites, rectal exam, and history taking. Chronic cases may require colonoscopy and biopsy to differentiate from Inflammatory Bowel Disease (IBD).

Treatment Protocols

Acute cases often respond to a bland diet, fiber supplementation (psyllium), deworming, and sometimes anti-inflammatory antibiotics like metronidazole or tylosin.

Prevention

Feeding a consistent high-quality diet, regular parasite control, and minimizing stress can prevent many episodes.

Prognosis

Excellent for acute cases. Chronic cases (like Histiocytic Ulcerative Colitis) require lifelong management but generally have a fair to good prognosis.
