C Diff Infection: Why Antibiotics Can Make You Sick and How to Treat It

This guide addresses C. difficile (C. diff) colitis, a condition often triggered by recent antibiotic use. C. diff is a bacterium that commonly lives in the gut but can rapidly multiply when antibiotics wipe out the protective good bacteria ("gut garden analogy"). As C. diff grows, it releases toxins that inflame the colon, causing symptoms like persistent watery diarrhea, abdominal cramping, and fever. Risk factors include recent antibiotic use, being 65 or older, and recent hospitalization. Diagnosis is simple, requiring a stool sample test for the bacteria or its toxins. Treatment for the infection involves targeted antibiotics, such as vancomycin. For frustrating recurrent C. diff, the highly effective treatment is a Fecal Microbiotic Transplant (FMT), which has cure rates consistently over 80%. Surgery to remove the colon is a very rare, last-resort option for life-threatening damage. Prevention emphasizes handwashing with soap and water and carefully discussing future antibiotic use with a doctor.
